I know this is not the best list to ask this, but does anyone know a good
tut,or has tried to setup the following:


MySQL   - Holds virtual domains and users database
Postfix - MTA (supports virtual domains)
Dovecot - POP3/IMAP server (auths by vpopmail)
Vpopmail- Virtual auth system (looks info on MySQL db)
