Hello, We are designing a scalable and redundancy IMAP/POP3 arquitecture. Users maildirs are in a SAN. There are N IMAP/POP3 servers, each one with its own SAN partition mounted. IMAP/POP3 sessions are balancing by a F5 balancer. Using mailhost LDAP attribute and PROXY_HOSTNAME in the imapd file is possible that a session was sent to right server where user maildir is. The problem is when a server is down. We would like to mount its partitition is any of active servers. The issue is that session always is sent to the inactive server. This could be solving allowing multiples values in the PROXY_HOSTNAME attribute (p.e imap1.domain.com, imap2.domain.com). In this case, when imap2.domain.com server is down, it would be possible mount its partition in any active server, p.e imap1.domain.com. Modifying the attribute (PROXY_HOSTNAME= imap1.domain.com, imap2.domain.com ) and restart the imap server, a session for the inactive server should be accepted by imap1 server, besides its own sessions.
This solution is similar to QMAIL cluster and let a redundancy arquitecture, although in a manual way but very effective. Is there any patch that allow multiples entries or several values to PROXY_HOSTNAME attribute. Has anyone make something similar?. Thanks. -- ___________________________________________ Antonio M.
