imho. (!) idk. what the fuzz is all about: yes, running a mail-server is a complex task - but nothing to write home about!! personally i prefer exim over postfix - because of its configuration: exim has a really flexible configuration-language which enabled me for example to operate qmail-ldap and exim-ldap from the same LDAP-tree - for migration purposes a few years ago -, using the qmail-ldap.schema vs postfix which insists heavily on the posix.schema ... additionally i prefer courier-imap over dovecot, for no apparent reason, just because i use it since ... ever. and i don't care about peoples performance who keep something like 10 k emails in their inbox/IMAP-folder ... yes, for this use-case dovecot is significantly faster / because of caching ;)) just my 0.02€ ps. i used qmail-ldap and qmail for over 20 years, and it was a really great piece of software - kudos to djb, but even brilliant code ages over the decades - for example, i didn't want to implement IPv6 support for outgoing mails myself / the available patch didn't cooperate well with the ldap-patch itself if i remember this correctly etc. pps. i would recommend: use an LDAP-directory for email ... openldap is an extremely lightweight and easy to operate piece of software. and its easy to replicate the db around - if you have multiple nodes in your mail-system - etc. ;)
