i am installing qmail on linux and creating on centrilized mysql server and one qmail server where user mailbox will reside.
I have two mail-relay servers where i have running pop3/imp,smtp and i want on relayserver users authenticate himself through centralized mysql database. But how ? mean how pop3/imap will communicate with remote database server for authentication.
Use Matt Simerson's tcpserver patch. This patch enables tcpserver to use a relays table in MySQL.
You can implement a POP-before-SMTP scheme where vpopmail puts an entry in the relays table and tcpserver can read the table for allowing those users to relay.
