Infomaniak IMAP and SMTP settings

How it works

1. Enter your email address — or just your domain. No password is asked for: this page connects to nothing.
2. We identify your provider — first from the domain if it is a known one (gmail.com, orange.fr, free.fr…), otherwise by querying your domain's DNS records to recognise the host behind it.
3. Copy the settings into your software — incoming IMAP server and outgoing SMTP server, with the port and encryption type, plus whether an app password is mandatory.

Use cases

• Setting up a mailbox in Thunderbird, Apple Mail or Outlook — when the client's automatic detection fails and it asks for the servers by hand.
• Preparing a transfer or a backup — our transfer, backup and analysis tools ask for exactly these IMAP settings.
• Understanding why a connection is refused — nine times out of ten it is a port that does not match the chosen encryption, or a missing app password.
• Configuring sending for a website or an application — the SMTP settings listed here are what a contact form or an invoicing tool expects.
• Finding a domain's servers on shared hosting — DNS detection often surfaces the real server name behind your domain.

What this tool doesn't do

• The tool does not test the connection: it gives you settings, it does not check that they work with your credentials. The mailbox tester does that job in seconds.
• It never asks for a password, and does not need one. Be wary of any site that demands your credentials in order to give you a port number.
• For an unknown domain, the suggested servers are hypotheses deduced from DNS and from naming conventions, not the truth: only your host can confirm.
• POP3 settings are not listed: all our tools, and nearly all modern usage, go through IMAP.
• Proton Mail exposes no direct IMAP: you have to go through the Proton Mail Bridge application installed on your computer, as the provider page explains.
