Hello!
Just wanted to ask what setup you use or recommend for large scale sites (~10k users, some hundreds of imap(s), smtp, webmail connections, about 5-10 mails incoming and outgoing per second):
- what smtpd? why? - what mail retrieval solution for which protocol? - if you offer webmail, what do you use? - it should be *nix software, preferable FOSS (free and open source software) - Which Antispam / Antivirus "protection" do you use? And what is the success rate?
I'm personally deep into qmail+patches+patches+patches of patches plus courier and dovecot.
The problem with qmail is that you need either a big patchset or a once patched setup and reuse that. Plus qmail really has some not-so-nice bugs.
On the other hand, there seems to be no MTA out there, that can be configured so easy like qmail (ever created a mail addr with "cp .qmail-template .qmail-domain-user" with another MTA?).
Oh, btw, "froehliche Weihnachten"
