I'm planning a large mail system with the postfix / lmtp / cyrus in murder / mysql (users table) configuration.
The system will be used in ISP-pattern: huge number of users (500k), high traffic of emails arriving by lmtp (15 emails per second), but low imap/pop3 demand (peaks of 2000 simultaneous users, more pop3 than imap). All configurations that I saw with cyrus was talking about imap/pop3 use, I never saw any published benchmarks|comparitions of cyrus with MTAs doing local delivery by lmtp|smtp. I have some questions: - Using storage with fiber in my ia32 backend servers, how much users can I squeeze in one box? (ie, how much emails/s in lmtp can I get AND how much concurrent pop3|imap users can one box cope with?) (P4's 2G RAM with fiber to an EMC); - I'm toying with the idea of create a mutant postfix mpudate-enabled that will deliver the email directly to the right backend, using the murders servers only to pop3 and imap. feasible or I'm getting nuts? -- Sergio Devojno Bruder <[EMAIL PROTECTED]> Haxent Consultoria http://www.haxent.com.br 55 41 9127-6620
