Iti sugerezi totusi sa mai studiezi alternativa postfix. Uite o configuratie
pe care eu o folosesc in productie (si deja e echipat cu antivirus, in
combinatie cu clamsmtpd, masina fiind P3/866MHz cu 128M RAM - e o masina
dedicata care primeste/trimite cam 1000 de mesaje pe zi - serviciul e critic,
facand legatura intre cateva banci si un cabinet de avocatura care opereaza
in Arhiva Electronica de Garantii Reale Mobiliare):
</etc/postfix/main.cf>
myhostname = mail.myhost.ro
mydomain = myhost.ro
inet_interfaces = all
mydestination = $myhostname, localhost.$mydomain $mydomain
mynetworks = 192.168.1.0/24, 127.0.0.0/8
home_mailbox = .maildir/
local_destination_concurrency_limit = 2
default_destination_concurrency_limit = 10
content_filter = scan:[127.0.0.1]:10025
virtual_alias_maps = hash:/etc/postfix/virtual
smtpd_client_restrictions =
check_sender_access hash:/etc/postfix/access,
permit_mynetworks,

Acum cativa ani am facut un test stress, un care combinatia
postfix/amavisd-new/spamassassin/clamav/cyrus-imapd a reusit sa inghita
cateva mii de mesaje in cateva minute (mailbombing-ul a fost initiat de pe
mai multe masini simultan, fiecare din ele trimitand 500 de mesaje).
