4.11.2. Authentication

Mutt supports three authentication methods with IMAP servers: GSSAPI, CRAM-MD5, and LOGIN (there is a patch by Grant Edwards to add NTLM authentication for you poor exchange users out there, but it has yet to be integrated into the main tree). Mutt will try whichever methods are available on the server, in order from most secure to least. That is, mutt will first try GSSAPI authentication (ie Kerberos V), then CRAM-MD5, and finally LOGIN (the worst possible choice - your password travels across the net in the clear).

There are a few variables which control authentication:

Note: The IMAP support has had very limited testing due to a lack of developers using it. It should work with the reference servers mentioned above, but if you need a more stable way to access your IMAP folder, consider using a specialized program, such as fetchmail.
