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.
