In December, I converted a mail system with about 30,000 users and six gigabytes of mail from sendmail/qpopper with the mail spool mounted on Unix clients via NFS, to a sendmail/cyrus/SASL system with all mail access via IMAP and POP3. I've been very pleased with the performance and reliability of Cyrus since that time. There were essentially no problems with it. In fact, most of our problems had to do with Unix mail clients, and with web pages needed to access Cyrus sieve scripts.
Now, I have a second somewhat smaller mail system to upgrade. This one is running sendmail-8.9.0 and cyrus-imapd-v1.5.19. I'd like to upgrade it to sendmail-8.12.x and cyrus-imapd-2.1.x. This version of Cyrus requires cyrus-sasl-2.1.x. However, I understand that sendmail will not work with that version of SASL. I'd like to use sasldb for secure passwords, as well as PAM via saslauthd for plain text passwords. In fact, I'd even like to keep the secure passwords in a network database, rather than in a local file-based database. How can I make this all play together? -- -Gary Mills- -Unix Support- -U of M Academic Computing and Networking-
