Bill hoy do you pass the mails from the MX servers to the mailstore server? you mount the unit with nfs, or you do it with smtproutes?
note that you can configure in vpopmail a mysql read server and a mysql write server, so it would be pretty easy so set up replication servers in mysql and use that. with round robin dns you could scale out more replication servers if in need. how many users/domains are you handling?

Right now I have several inbound MX boxes that do spam/virus filtering and accept mail from the outside world. They all deliver to one beefy server with a big RAID that stores the mail (we call it the mailstore server), and handles POP3/IMAP connections from users. There is a seperate webmail server running squirrelmail, and another server with a fast RAID 10 that does all the outbound SMTP and takes messages in from users and bounces from the other servers. The whole thing is qmail/vpopmail based, with spamassassin and clamav on the inbound MXes. Right now we're planning on splitting out the MySQL stuff (right now that runs on the mailstore server) onto 2 or more MySQL-only servers since they handle a lot of queries for vpopmail (MySQL backend), squirrelmail (user prefs), and spamassassin (user prefs). We'd like to be able to scale the system with minimal use of hardware load balancers due to cost. Most of the examples I see out there use a big server running NFS and several smaller servers that handle user queries for POP/IMAP/etc., but it seems like that would have some issues keeping sessions with authentication, and most of the examples are out of date. Our inbound works great -- we can just add more MX servers, but I'm concerned about the POP3 and IMAP connections, and possibly the outbound SMTP if we need more than one server. Does anyone have some expierience to share or maybe a link to some newer example info? -Bill ***************************** Waveform Technology Systems Engineer
