Mbsync and imap login problem

Written by Solène, on 17 May 2016.

I have not found any answer about this so I share my fixed. I wanted to use mbsync with one IMAP server and encountered the following error.

IMAP command 'AUTHENTICATE DIGEST-MD5' returned an error: NO Authentication failed

A fix is to add the following to your ~/.mbsyncrc IMAPAccount declaration.

AuthMechs LOGIN

Using LOGIN instead of DIGEST-MD5 is still secure if you have an encrypted connection (IMAPS or STARTTLS). The login will be given plaintext inside the connection.
