Re: [courier-users] Synchronisation of IMAP-Mailboxes between multiple servers
I imagine that others have the same problem. How do you synchronize (live) IMAP mailboxes between servers ? How about running a distributed filesystem like Coda between the boxes, and setting it up to replicate, so that each box would have the same data on it. The replication would be automatic, so wouldn't have to do any manual work. I have the same project in mind. I am getting information about DRBD that is a module that replicate the data to a network block device in another server. Do you are using CODA in production? Sam, would be great if courier-imap already have this possibility. That will make courier-imap a reference for High-Availability Imap server. Augusto Pizarro. ** ___ Have big pipes?

[courier-users] Synchronisation of IMAP-Mailboxes between multiple servers
Hi! At the place I work for, we are using Courier-IMAP/POP3 with SSL for several hundred usrs (University-environment) and are very satisfied with it's performance and memory footprint. Currently we only have one mailserver for IMAP but we'd like to make this setup redundant. For incoming mail, that's easy. The MTA just needs to pass another copy to the second box before local delivery. But in an IMAP context, we'd also need to replicate the mailboxes to a second machine so it can take over in case the main server becomes unavailable. I imagine that others have the same problem. How do you synchronize (live) IMAP mailboxes between servers ? Would just rsynching the Maildirs be sufficent ? Is there any way to tell Courier to lock a specific Mailbox so it can't be changed while rsync copies a specific user's mailboxes ? Or is there any better way to achive high availability ? Any tips or experiences would be greatly appreciated. -- Oliver M.
