I have been having one heck of a postfix with imap and ssl to work on SLES 8 for AMD64. This is our only server at the current time, so it is fireall, app server and email server. It has plenty of power, so that is not an issue. So, looking through the README's I found /usr/share/doc/howto/en/html/Postfix-Cyrus-Web-cyradm-HOWTO which seemed to suggest that postfix with cyrus was the best approach. Being as we only has a small number of email users, going to a MySQL database seemed like overkill. Plus these instructions build most everything from source. With SLES 8 for AMD64 binary RPMs is it possible to get postfix and cyrus working with TLS/SSL for imap and pop? If so where could I find better HOWTO's. I have spent a lot of time reading mailing lists but so far no success. Otherwise, would it make sense to obtain the SuSE 9.0 for AMD64 source RPM's for postfix, cyrus-imap and cyrus-sasl2 and compile those on SLES for AMD64? I have read that postfix 1.x will not work with saslauthd. Thank you - Richard BTW, here is the error I am currently getting using the SLES rpms: rnmixon@kingfish:~> imtest -m shadow -a rnmixon kingfish S: * OK kingfish.FromLtoJSoftware.com Cyrus IMAP4 v2.1.16 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=GSSAPI AUTH=CRAM-MD5 AUTH=DIGEST-MD5 X-NETSCAPE S: C01 OK Completed Authentication failed. no mechanism available Security strength factor: 0 When I try and connect from a Windoze machine with Outlook here is what I get: Mar 19 07:30:28 kingfish master[32466]: about to exec /usr/lib/cyrus/bin/imapd Mar 19 07:30:28 kingfish imaps[32466]: executed Mar 19 07:30:28 kingfish imapd[32466]: accepted connection Mar 19 07:30:29 kingfish imapd[32466]: starttls: TLSv1 with cipher RC4-MD5 (128/128 bits reused) no authentication Mar 19 07:30:29 kingfish imapd[32466]: OTP unavailable because can't read/write key database /etc/opiekeys: No such file or directory Mar 19 07:30:29 kingfish saslauthd[31370]: AUTHFAIL: user=rnmixon service=imap realm= Mar 19 07:30:29 kingfish imapd[32466]: badlogin: vdsl-130-13-89-148.phnx.uswest.net[130.13.89.148] plaintext rnmixon SASL(-13): authentication failure: checkpass failed Mar 19 07:30:45 kingfish master[31525]: process 32439 exited, status 0
