This guide details the security measures implemented as part of the Infomaniak email offers to detect abusive and abnormal uses of an email address. These measures protect you from malicious use of your computer or account.

Number of recipients per email

Regardless of the chosen email offer, whether free or paid, the total number of recipients per message is limited to 100.

This restriction applies regardless of the field used to insert the recipients' email addresses (To, CC, or BCC).

For sending emails to a large number of recipients, it is strongly recommended to use a newsletter tool like the one offered by Infomaniak.

Other email limitations

• Limits on outgoing emails per 24 hours
• Size limitations at the email level

• If you want to make adjustments for different reasons, sometimes linguistic, then read the guide below to modify these special folders:
  • drafts
  • messages sent
  • Trash
  • archives
• This allows you to customize the synchronization of these folders with IMAP clients such as Outlook, iOS Mail, Thunderbird, Spark, etc.
• Be careful this does not change the shelf-life limit e-mails placed in some of these special folders.

Access from the Mail Infomaniak Web app

In case of trouble

There is no need to contact Infomaniak Support if your email address works well outside of the application.

The most common error involves using an incorrect password.

The troubleshooting guides help you resolve any issues:

• Check out the solutions provided in this other guide regarding email in general
• … and if your application no longer works for sending (e.g., SMTP server disconnected or absent) or since a password change, refer to this other guide.

This guide helps you solve various issues related to the implementation and use of a DMARC policy with your email.

Refer to this other guide if you encounter a DMARC issue specifically when using Google services.

DMARC error or rejection...

...during a redirection even though the initial destination address was able to receive the email (SPF error)

Email redirection without SRS causing an SPF error

Let's say you have set up an email redirection from your email address "user@example2.com" to your new address "user@yourdomain3.com", without using SRS. When someone sends an email to "user@example2.com", it is automatically redirected to "user@yourdomain3.com". Example:

• sender: john.doe@gmahoo1.com
• initial recipient: user@example2.com
• final destination: user@yourdomain3.com (SPF error)

In schematic termsWhen John sends an email to "user@example2.com", the email is redirected to "user@yourdomain3.com". However, the mail server of "yourdomain3.com" still sees the email as coming from "john.doe@gmahoo1.com".

In detailWhen John sends an email to "user@example2.com", the email is redirected to user@yourdomain3.com" that is to say that the envelope sender address will remain john.doe@gmahoo1.com but the envelope recipient address will be changed to user@yourdomain3.com.

This will generate an SPF error, because the SPF of the gmahoo1.com domain does not authorize the IP addresses of the example2.com SMTP servers to send emails for its domain.

This SPF error will cause the DMARC rejection.

If you want the redirection to work without error, it is necessary for the provider of the email address that is redirecting to perform the redirections with SRS.

How does email redirection work at Infomaniak?

When you receive an email on an Infomaniak address and it is redirected to another email address, the sender's email address is rewritten to reflect the redirection. Thus, the recipient's mail server sees the email as coming from your own domain.

In summary, the use of SRS in email redirection helps maintain the integrity and security of emails while ensuring that authentication mechanisms such as SPF and DKIM remain valid.

...related to an incorrect DNS entry

Malformed DMARC Record: if the DMARC record is not correctly formatted, this can cause errors. Make sure that the tags and values are correctly specified.

Invalid DMARC Policy: errors may occur if the specified DMARC policy is not correct. The possible values for the policy are "none", "quarantine" and "reject". An incorrect value can cause issues.

Multiple DMARC entries: having more than one DMARC entry in the DNS zone is considered an error.

If you have multiple DMARC records, mail servers may interpret this differently, which can lead to unpredictable behavior. Fix this by consolidating your DMARC settings into a single entry.

Check your current DMARC entry using dedicated tools like those below:

• https://dmarcadvisor.com/dmarc-check
• https://mxtoolbox.com/dmarc.aspx

...related to a send that does not comply with SPF and/or DKIM

A DMARC error or rejection related to SPF or DKIM can occur if the SPF or DKIM authentication mechanisms are not correctly configured or if they are not aligned with the domain's DMARC policy.

This can for example happen if you send an email from your Infomaniak email address using another provider's SMTP server. To resolve this issue:

• Check the overall security of the Mail Service.

I send an email from my Infomaniak address and I receive an error email of type "Reject DMARC

To resolve this issue:

• Check the overall security of the Mail Service.
• Perform a send test from the Webmail mail.infomaniak.com and/or check the server settings of the email software/client.

I send an email from an external email address (Microsoft, Google, Yahoo, Orange, …) and Infomaniak rejects my email with a DMARC error

To resolve this issue:

• Check with the sender's email provider to ensure that emails are sent according to their configuration recommendations and, if necessary, contact the sender's email provider for more information.

I want to receive an email at my Infomaniak address but the sender informs me that they receive a DMARC error when sending to my address

To resolve this issue:

• In this case, the email was blocked due to a violation of the DMARC policy that the sender has implemented on their domain; it is necessary for the sender to contact their email provider or the administrator of their service to inform them of the situation.

This guide provides the most common IMAP server addresses. These can be used to copy the content of your old email addresses to your Infomaniak email address.

IMAP Server Addresses

This guide details the priority actions to take if you do not see any difference between your website after a change you made to it, and its version before the change. These tips are also valid if you encounter issues while using the Infomaniak product interface.

Preamble

• While browsing, a web browser saves the data viewed in a reserved space, this to avoid asking the server again for the data already viewed, to save time and resources.
• Your cache can contain a lot of data and sometimes the browser gets confused. Websites may then display incorrectly or show an outdated version.
• Clearing the cache ensures that you have the very latest version of the page or folder consulted.

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:

1. Do not send unsolicited mail or mass messages to unknown recipients.
2. Regularly sort the list of recipients used.
3. Do not engage in phishing or cybercriminal activities.
4. Ensure the highest level of security where your emails are used:
   1. strong password
   2. software up to date
   3. operating system (iOS, Android, Windows, macOS, etc.) up to date
   4. 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:

1. Follow the procedure of the mentioned organization (e.g. http://www.barracudacentral.org) to get your address removed from the list.
2. Temporarily switch your Internet service provider or connection method - WIFI vs 4G/5G - to send your messages.
3. Inform your contact and their email provider to take the necessary steps and/or to stop using an unreliable RBL.
4. 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.
