This guide explains how to display and forward the headers of an email.
Preamble
- An email is composed of a header (
header) and the actual content of the message (body, body of the text). - Most email software/clients do not directly display the headers, but displaying or forwarding them allows Infomaniak support to identify the issues encountered.
- The headers of an email provide various information such as:
- the sender
- the recipient
- the date
- the subject
- The servers involved in the transmission between the sender and the recipient
Display the headers...
... on Mail Infomaniak
To display the headers of an email from the Mail Infomaniak interface:
- Click here to access the Web app Mail Infomaniak (online service ksuite.infomaniak.com/mail).
- Open the concerned message and click on the action menu â‹® on the right.
- From the menu that appears, select View headers:

To display the headers if you are using an external mail application, refer to this other guide.
Forward email headers
To forward the headers of an email, in response to a support request or to the recipient of your choice, either...
- ... copy-paste the headers displayed according to the method above.
- ... forward the email message.
However, for the headers to be present, it is essential to forward the message not in the body of the message but as an attachment only. The email as an attachment will be in the .eml format and this file contains all the necessary headers.
A third method for complete email forwarding is explained in this other guide.
This guide explains how to add or modify a sender name that will be used when sending your emails from the Infomaniak Web app Mail (online service ksuite.infomaniak.com/mail).
Preamble
- This full name (usually a first and last name) is linked to your email address.
- It appears in place of or next to your email address for the recipient of your email.
- Note that if they have already added you to their address book with a name/first name, it is probably this one that will be displayed for them.
Default behavior
By default, without any specific configuration or signature, no name/first name will be displayed when you use the messaging service. You are writing a new message:
The message is received in this form:
Add / modify the sender name
To access the full name for your Infomaniak messaging service:

This guide explains how to disable two-factor authentication, also known as two-factor authentication (2FA) or two-step verification for logging into Infomaniak Manager (manager.infomaniak.com) or Infomaniak Mail (ksuite.infomaniak.com/mail).
For security reasons, Infomaniak support will never disable an enabled login validation method on an account following a simple request. You must follow the procedures below.
Disable 2FA
If two-step verification is enabled and you want to disable it:
- Click here to access 2FA management on Infomaniak Manager.
- Click the Remove button to remove security:

- If the red button is inactive / grayed out…

- … you will need to contact your administrator because there is probably an upstream security option that prevents you from disabling 2FA:

- If the red button is inactive / grayed out…
- Enter the password to log in to your account.
Note: if you were using the SMS authentication method, once disabled, you will only be able to re-enable this method if you are resident in CH / FR / BE / DE. Outside these countries, you will need to use kAuth or any OTP application.
In case of a problem
Obviously, the procedure above requires logging in one last time with two-factor authentication in order to then be able to disable it.
If you do not have access to the kAuth application or the device that receives the validation SMS, there is no point in calling Infomaniak; in this case, no choice, you will have to provide a number of security elements manually or via the Infomaniak Check (kCheck) app to regain access to your account:
- Click here to access the Infomaniak Manager login page.
- Enter the username and correct password.
- When prompted for additional authentication, click on alternative methods:

- Choose to enter one of your recovery codes if you had downloaded the sheet when activating 2FA:

- Otherwise select the last option to request help to access the form allowing you to submit your identity documents and recognition selfie:

- Follow the procedure to the end and be patient:

Manually add the email address to the application
Prerequisites
- Create the address within my kSuite or on a Mail Service (Mail Service only, or existing within a kSuite).
- Test the email address password (do not confuse it with the one used to log in to the Infomaniak interface).
- Check on the Mail Service that the automatic diagnosis is correct.
- Have added the email address in question to Mail Infomaniak to use the synchronization assistant and for the Apple profile to work on your devices.
To configure the messaging application:

- Incoming IMAP server = mail.infomaniak.com
- IMAP port = 993 (with SSL)
- Outgoing SMTP server = mail.infomaniak.com
- SMTP port & encryption protocol and command/method to activate this protocol:
- Prioritize port
587+ STARTTLS: this is the official technical standard and the most compatible method with the majority of modern systems for authenticated submission. - Tolerate port
465+ SSL/TLS only as a compatibility option or alternative, specifying that it is implicit encryption, but that 587 remains the recommended choice.
- Prioritize port
- Username = full & complete email address ( ? )
- Password = the one assigned to the email address you want to access ( ? )
- Authentication required to send emails:
- It is activated in the SMTP settings of your application.
- Check "use the same parameters as the incoming server" or according to the software/email clients, enter a username (= full & complete email address) and its password.
Refer to this other guide if you are looking for information about other compatible email ports and protocols.
In case of problem
There is no need to contact Infomaniak Support if your email address works well outside the application. The most common error concerns the use of an incorrect password. The troubleshooting guides help you resolve any potential issues:
- Refer to the solutions given in this other guide regarding email in general.
- Delete any Apple configuration profiles linked to your Infomaniak email before starting the configuration again.
And if your Apple Mail no longer works since a change of email password, refer to this other guide.
This guide details what can be searched for on the Web app Mail Infomaniak (online service mail.infomaniak.com) or other kSuite services. To search on kDrive, refer to this other guide.
Search for an email
You can perform a global search (among all the directories of the Web app Mail Infomaniak) either in the body of the message, or in its subject, or among its senders/recipients, large attachments, etc. If you want to find a message in a specific directory, select it first.
Advanced search is accessible from the dropdown arrow ‍ to the right of the search field at the top of your Mail:
To search for the trace of an email or know its activity, you can also search in the logs of an email address.
Email search with a mail software/client
To find out how your specific email application performs searches, consult its documentation. For example, desktop apps (desktop applications) Thunderbird and Outlook can synchronize messages locally and perform local searches, while other applications may prefer to search on the IMAP server. In this case, the email client sends a search command to the server, which then searches all messages stored on the server and returns the results to the email client.
Search for a contact
You can search for an address book, a group, or a person among your contacts using the search field at the top of your Infomaniak address book:
Search for an event
You can search for calendars, events, rooms, including among their descriptions and the people associated with them:
This guide explains how to export the contents of an email address hosted by Infomaniak.
Preamble
- Infomaniak does not offer an export (e.g.
PST) but keeps your emails without limit* for the entire duration of your contract with integrated backups. - The manual export offered works on Windows: you can thus save your emails in a single archive that is easily restorable.
- For additional help, contact the support of the software/email client used, or a partner.
Manual export
To export all the messages contained in your email address hosted by Infomaniak:
- Install the free application Thunderbird.
- Configure the email address in question using IMAP (to include subfolders).
- Make sure all desired content is present (synchronize the box from the beginning - not just the last 30 days for example).
Then…
- … or you install the free application BackupThunderbird which allows the creation of an archive (encrypted if necessary) and later restoration…
- … or you can simply display the hidden files in Windows, then find and save this folder profile
C:\Users{USER}\AppData\Roaming\Thunderbird\Profiles{PROFIL_USER}\
as it contains all your emails.
Download emails locally
Another solution (not recommended) could be to configure a software/email client by choosing to receive emails via the POP3 protocol, which will download the messages locally. Only the inbox is affected.
* within the framework of normal use of a shared service, in accordance with Article 1 of the particular conditions of the Mail Service

This guide presents the operation of RBLs, the questionable policy of some of them and the means to resolve a possible email block.
Preamble
- RBLs (Realtime Blackhole Lists) or DNSBLs (DNS Black Lists) are lists containing addresses / IPs / provider names / servers, known as major spammers.
- These are often large, generalized blacklists that help identify unwanted messages and their senders, maintained by certain providers (smtpcheck, uceprotect: non-exhaustive list)…
Adding the email address to the RBL
When an email address is identified as belonging to an unwanted sender, it is blocked to prevent the receipt of unsolicited mail. A block in the RBL does not expire. Addresses will be listed indefinitely.
If you receive a message indicating that your email address is blocked by RBL, this means that Infomaniak's security system has detected suspicious or unwanted activities associated with this email address. This can include mass sending of unsolicited mail, participation in phishing campaigns or other malicious behaviors.
Resolving an email block (RBL)...
… if the error mentions your address and RBL
If you encounter errors of the type
anna.a@domain.xyz is rbl blacklisted - http://chk.me/rbl
when sending an email and you think it's a false positive, contact Infomaniak support.
To prevent your email address from being blocked by the RBL blocking system in the future, follow best practices for email use:
- Do not send unsolicited mail or mass messages to unknown recipients.
- Regularly sort the list of recipients used.
- Do not engage in phishing or cybercriminal activities.
- Ensure the highest level of security where your emails are used:
- strong password
- software up to date
- operating system (iOS, Android, Windows, macOS, etc.) up to date
- associated domain configuration up to date
… if the error mentions an organization like Sorbs or Barracuda
If you encounter errors of this type
554 5.7.1 Client host blocked using sorbs
or similar:
- Follow the procedure of the mentioned organization (e.g. http://www.barracudacentral.org) to get your address removed from the list.
- Temporarily switch your Internet service provider or connection method - WIFI vs 4G/5G - to send your messages.
- Inform your contact and their email provider to take the necessary steps and/or to stop using an unreliable RBL.
- Wait a few hours and try again.
Fewer and fewer professionals (ISP, hosts, etc.) use providers like Backscatterer / UCEPROTECT which are primarily profit-driven. There are many other highly effective lists, such as ABUSIX or SPAMCOP, which are well-maintained and genuinely aimed at fighting spam, one of the priorities of Infomaniak.
This guide explains how to set up and customize the global display of the Web app Mail Infomaniak (online service ksuite.infomaniak.com/mail).
Preamble
- The general settings affect all email addresses currently attached to your account on Mail.

This guide covers Infomaniak products that integrate the use of artificial intelligence (AI), including kSuite, kChat, kDrive, Mail, Site Creator and notably through Euria.
Preamble
- The use of AI at Infomaniak is based on a transparent and ethical approach.
- Each service integrating AI follows strict principles to ensure reliable and respectful use:
- the protection of information is guaranteed by complete data processing within infrastructures located exclusively in Switzerland, thus ensuring full control over digital sovereignty,
- the results generated are never used to train models or for advertising purposes,
- and AI is not intended to replace humans, but to assist them.
kChat
The AI integrated into kChat helps save time in exchanges: it can rephrase sentences, generate quick responses, correct spelling, or adjust the tone of a message. The user retains full control over the suggestions, which are local to each session only.
Mail Infomaniak
In the Mail application, Euria assists in writing emails. It can generate content from a few keywords, rephrase or structure a message, adapting to different registers. Nothing is sent automatically, and the user can modify the texts at any time.
Site Creator
An AI-based writing assistant allows Site Creator to quickly generate content tailored to different types of web pages. This service is useful for people launching a site and looking to produce clear, optimized, and relevant texts.
kDrive
On kDrive, artificial intelligence is used at two complementary levels to simplify document management.
Euria allows interaction with text files stored in the drive. This module can answer questions about the content of a document, summarize, translate, or extract useful information. It is particularly effective for reading reports, understanding complex texts, or quickly generating an overview of a file.
AI on demand with AI Tools
Infomaniak provides a platform that allows easy integration of open-source models into custom projects. It is possible to leverage text analysis, content generation, translation, or other AI uses via on-demand calls. These services enable developers to benefit from high-performance AI without relying on closed or proprietary solutions.
Responsibilities of the parties
Data provided to the AI
- The AI of Infomaniak is currently based by default on these models.
- Among them, Mistral, Whisper, DeepSeek, Llama, granite…
- By using a writing assistant, the messages and requests addressed to the AI are exclusively processed in Switzerland by Infomaniak's infrastructure.
- No data is processed or shared with a third party.
Data provided by the AI
- The language model generates text based on the data it has assimilated during its training, devoid of consciousness, intentions, or moral responsibilities.
- It is crucial that the user is aware that the information generated by the model is not always accurate and should not be considered an infallible source of information.
- They must exercise their critical judgment and verify the information provided by the assistant from reliable sources when necessary.
- For example, if a person uses the model for crucial tasks such as medical, legal, or financial advice, they must take additional precautions to confirm the information coming from the model.
- In case of inappropriate or dangerous use of this assistant, the responsibility lies with the user who takes these actions.
