When you need one, postfix is probably the best choice. However, I'm doing without one. I let the MUAs (Kmail and K-9 on Android in my case) directly access the SMPT account at my mail/web provider, for sending mail.

This would be the private mail server in question. I strongly recommend dovecot.

I've had used fetchmail as well. But I've switched to getmail, because fetchmail didn't work so well... Getmail is unproblematic, and it can integrate a spam filter (as well as other filters).

Hmm..  I'm doing without one.
