fastmail seems to be rejecting "AUTHENTICATE OTP". When I run mutt with "-d 9", I get a full report of the communication:
< * OK IMAP4 ready > a0000 CAPABILITY < * CAPABILITY IMAP4 ... IDLE AUTH=OTP SASL-IR > a0001 AUTHENTICATE OTP ******************* < a0001 BAD invalid command (My dovecot system uses AUTH=PLAIN since it's already over SSL.) Under Dapper, it seems that mutt falls back to "LOGIN": > a0001 AUTHENTICATE OTP < a0001 BAD invalid command imap_auth_sasl: IMAP4 I... AUTH=OTP SASL-IR failed > a0002 LOGIN "[EMAIL PROTECTED]" "*****" < a0002 OK User logged in This seems to say you can specify "LOGIN" as the auth method, but it doesn't work for me: http://www.mutt.org/doc/devel/manual.html#imap-authenticators -- edgy beta - mutt sasl authentication broken https://launchpad.net/bugs/65821 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
