Hi, thx for the people who showed me the good documentation ;-)
Ok. I have now tracked the problem a little bit. root@gutmann:/usr/lib# imtest -m login -a cyrus localhost S: * OK gutmann Cyrus IMAP4 v2.1.11 server ready C: C01 CAPABILITY S: * CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ MAILBOX-REFERRALS NAMESPACE UIDPLUS ID NO_ATOMIC_RENAME UNSELECT CHILDREN MULTIAPPEND SORT THREAD=ORDEREDSUBJECT THREAD=REFERENCES IDLE STARTTLS AUTH=CRAM-MD5 AUTH=DIGEST-MD5 AUTH=OTP S: C01 OK Completed Please enter your password: C: L01 LOGIN cyrus {8} S: + go ahead C: <omitted> S: L01 NO Login failed: generic failure Authentication failed. generic failure Security strength factor: 0 . logout * BYE LOGOUT received . OK Completed Connection closed. Looks like for some reason cyrus cannot authenticate my users. I use sasl 2.1.10. Here is my /etc/imapd.conf: configdirectory: /var/imap partition-default: /var/spool/imap admins: cyrus sasl_pwcheck_method: saslauthd Regards, Michael Obster
