This guide explains the protocols and ports that can be used with Infomaniak email services (Mail Service in particular).
Prerequisites
It is imperative to use only the server name mail.infomaniak.com
when prompted during the configuration of email software or applications, and this applies to both incoming and outgoing mail settings.
If you specify another server name, mail errors may occur.
Recommended Ports
It is recommended to use only the following protocols and port numbers when prompted during the configuration of email software or applications:
- port
993
(secure port for receiving messages via IMAPs - incoming mail) - port
465
(secure port for sending messages via SMTPs - outgoing mail)
It is imperative to enable SSL / TLS authentication
when prompted during the configuration of email software or applications, and this applies to both incoming and outgoing mail settings.
Without enabled authentication, mail errors may occur.
Other Supported Protocols
- port
143
(standard port for receiving messages via IMAP) - port
110
(standard port for receiving messages via POP3) - port
995
(secure port for receiving messages via POP3s) - port
587
(alternative port not recommended for sending messages via SMTP)
- TLS authentication on SMTP ports 587 and 25 (not recommended)
- STARTTLS authentication for IMAP, POP3, and SMTP
- SMTP authentication (either LOGIN or PLAIN)
The Infomaniak API does not provide any connection to email because IMAP and SMTP are the "APIs"; for this purpose, use a Python library like https://docs.python.org/3/library/email.examples.html and https://docs.python.org/3/library/imaplib.html or any library using IMAP and SMTP.
To display emails using php:imap_open("{mail.infomaniak.com:993/imap/ssl}", $email, $password);
This guide explains how to switch, in an email software, from a POP configuration to an IMAP configuration for the same mailbox. Indeed, for various reasons, it is highly recommended to use the IMAP protocol instead of POP.
Switching from POP Protocol to IMAP Protocol
If your email address is already configured with the POP protocol in your email software (Mozilla Thunderbird, Microsoft Outlook, etc.), it is not possible to switch directly to the IMAP protocol on the same account. Most common email software does not allow you to modify an existing POP3 account and set it to IMAP instead.
The solution is to add the same email account but with the IMAP protocol to your email software and then move your messages and folders from the POP account (on your computer) to the IMAP account (on the mail server).
With Microsoft Outlook
Some versions of Outlook, such as 2016, prevent the simple addition of a second account with the same name (identical email address).
To work around this, you need to add the account from the Profiles section:
From there, you can add the additional account in IMAP:
- Configure the new email account with the IMAP protocol (the same account as configured in POP but this time in IMAP)
- Move one folder at a time by dragging them to the inbox of the new account configured in IMAP
- Wait while the elements are transferred (this may take a long time depending on the volume to be transferred to the server); the activity is indicated at the bottom of the window
With Apple Mail
Deleting the email account configured with POP also deletes the messages it contains. Therefore, it is recommended to disable the POP account instead of deleting it!
Once the POP account is disabled, follow our guide to configure your email address in Apple Mail using IMAP.
When you are done, all you need to do is drag the messages from your POP account's folder structure to the folder structure of the new IMAP account.
Thank you for managing your emails with Infomaniak!
You now have access to one or more email addresses hosted with Infomaniak that you can use and synchronize across multiple devices, as well as for contacts and calendars.
Recommendations
- follow the wizard to configure synchronization for your devices (macOS, Windows, Linux, iOS, Android) and common email client software (Outlook, Microsoft 365, Thunderbird, Apple Mail, eM Client, etc.)
- use directly email, contacts, and calendars/schedules in a web browser thanks to Mail Infomaniak (mail.infomaniak.com)
- download Infomaniak Mail app for iOS / Android devices

Password Change for Email
You can change an email password:
- from the Manager under Mail Service
- from Mail Infomaniak directly
Apply the New Email Password
You must then update your applications & devices on which the email address (whose password has been changed) was installed and connected. Read the guides:
- Apple Mail (macOS / iOS)
- Android Mail / Gmail (different versions)
- Microsoft Outlook (different versions)
- Windows Mail / Courrier
- Mozilla Thunderbird
In Case of Problem

You don't yet manage your emails at Infomaniak?
kSync is a free application offered by Infomaniak for smartphones with the Android operating system (Samsung, Huawei, Google Pixel, etc.). It allows you to easily synchronize contacts, calendars/agendas, and tasks between your mobile devices and the tools offered within Infomaniak Mail:
- calendar.infomaniak.com for managing calendars/agendas
- contacts.infomaniak.com for managing contacts/address books
Why Install kSync?
Firstly, configuring synchronization at the email level does not mean that contacts & calendars will also be synchronized. Email syncs via the IMAP protocol, while your contacts & calendars can be synchronized using the cardDAV and calDAV protocols. To facilitate this synchronization on Android, it is recommended to install kSync. On iOS (iPhone, iPad, etc.), it is recommended to use an Apple profile, which can be downloaded from our configuration assistant.
Microsoft (which includes Outlook) has its own format that is not compatible with cardDAV and calDAV. Therefore, it is not possible to synchronize contacts & calendars with Infomaniak on Outlook mobile (smartphone).
Prerequisites
- Have an Infomaniak Mail account
- Download and install kSync on an Android device
What would you like to do?
- Configure kSync
- Add a new address book or calendar from kSync
- Synchronize tasks between Infomaniak Mail and your Android devices
- Force synchronization with kSync
- Generate a specific password in case of two-factor authentication
This guide helps you identify and correct errors encountered when trying to use your email software like Microsoft Outlook, Mozilla Thunderbird, Apple Mail, etc.
Check this guide if you receive a "mailer daemon" or "delivery failure" message after sending an email.
Always use...
- the unique server name:
mail.infomaniak.com
(for IMAP receiving servers and SMTP sending servers) - the correct incoming/outgoing port numbers
- authentication in the settings when prompted, and enter the username (your full email address) and password in the fields for mandatory authentication if necessary
- the correct email address password, which is usually different from the username used to log in to Infomaniak (click here to check if you are using the correct password and, if necessary, change your email address password)
- an existing email address that must have been actually created (or defined as an alias)
- only one protocol at a time (never check an email with devices configured in POP3 for some and IMAP for others as these two protocols do not work well together)
Always try to...
- compare recommended settings for the software used, especially if you have just changed the password on the Infomaniak side
- retrieve your emails using a different network (WiFi, tethering from 4G/5G, or any other internet connection)
- temporarily disable your security software (antivirus, firewall, VPN...); if you can then retrieve emails normally, contact the publisher of the security software you are using
- type your password in plain text in a text editor; depending on your keyboard configuration, the A key may refer to the letter Z and the Q key may refer to the letter A...
- restart and try again to send/receive: some applications require validating the configuration settings window several times or require them to be restarted to take into account their new settings
- compose a new message after modifying your settings: a message being drafted that would be saved in the Drafts folder may not take into account any configuration changes

but also:
- "573 Antispam: Connexion authentifiee pas possible. Veuillez utiliser le port 587 a la place du port 25."
or "An operation on the server timed out. The server may be down, overloaded, or there may be too much net traffic."
or "le délai imparti est dépassé" with an error number following it (421, or 573 for example).
Most ISPs (Internet Service Providers) blocked SMTP port 25 many years ago. Therefore, you should never specify port 25 as the SMTP port. To be able to send emails nevertheless, use the recommended ports.
This guide explains how to view folders in your Infomaniak mailbox using email software with the IMAP protocol.
Default Folders
The various generic folders are created by Mail (Infomaniak webmail) during the very first connection to the interface. Therefore, some IMAP software may not display folders if no connection has been made to Mail previously.
Even if they are present in Mail, some folders may not appear in your email software configured with IMAP.
Force IMAP Folder Synchronization
In your usual email software, look for the term "IMAP folders" and/or "subscribe," "subscription," etc. Otherwise, check in a possible TOOLS menu...
Configuration in Microsoft Outlook
In some cases, after configuring an Infomaniak address in the Outlook email software, certain folders may not appear. In this case, it is necessary to check the synchronization with the subscribed folders in Outlook:
- Start the Outlook software on your computer.
- Right-click the Inbox folder from your Infomaniak email address.
- Select: IMAP Folders
- Uncheck the option: When displaying the hierarchy in Outlook, only show subscribed folders
- Click Apply.
More information: search engines
Configuration in Thunderbird
In some cases, after configuring an Infomaniak address in the Thunderbird email software, certain folders may not appear. In this case, it is necessary to manually select these folders from the Thunderbird subscription menu:
- Start the Thunderbird software on your computer.
- Right-click the relevant Infomaniak address and select the Subscribe menu.
- Check the missing folders.
- Click OK to confirm your selection.
