smtp		25/tcp		mail
ssmtp		465/tcp		smtps		# SMTP over SSL

ak mam smtp tls enable, tak kryptovana komunikacia stale bezi na porte
25, pokial servery navzajom zistia z EHLO, ze maju 250-STARTTLS -
vychadzam z pouzivanej konfiguracie postfixu

- This is an SSL/TLS enhancement package for postfix.
  It realizes (well, or at least should, once it is finished) the
  STARTTLS extension to SMTP as described in RFC2487 and used
  by Netscape 4.5x.

# only used by postfix-tls
smtps .... smtpd -o smtpd_tls_wrappermode=yes
587   .... smtpd -o smtpd_enforce_tls=yes

netvrdim, ze to odporuje vasmu tvrdeniu - nechcem sa hadat ;-)))
