Ok, so I'm trying to provide a good email server solution.
The things I need/want are virtual domain hosting, spamfiltering, and the ability to redirect spam to a "found spam" folder of sorts.
Everything I've found so far solves some of the problems but sucks in other regards.
Sendmail, easy setup, easy to maintain, pure crap for virtual domain hosting, I really would like email@example.com and firstname.lastname@example.org to both be able to use their username as a login, otherwise the more virtual domains I get, the more stupid my accounts are going to look.
Qmail solved that problem nicely with vpopmail. Problem being though that with qmail I lost the support for that lovely program MailScanner that worked so well with sendmail. yes I know there's qmail-scanners but so far it reall really does seem weaker and harder to configure and just royally a pain to setup up, let alone for user-specific spam filtering settings.
So I'm hoping that some people that actually run ISPs and the such will read this and tell me what works best for them, because I really don't know what to do from here.
I know this is noobish but I've backed myself into a corner on this one promising more than I could deliver, I'm tempted just to use sendmail, mailscanner, and usernames like email@example.com firstname.lastname@example.org but I really don't want to have to.
