[CentOS] Mail server - MailScanner/Baruwa/postfix/...

Hi All ;)

Currently I am gathering info about possible components for a mailserver. I
think that MailScanner/Baruwa/postfix will be a good choice. I set up a
similar system (with MailWatch instead of Baruwa) about 3 years ago and had
very good experience ;) What do you think about MailScanner/Baruwa now? Do
you maybe use any good alternatives and can recommend them?

Thanks for all help ;)

Best regards,
Rafal.
