Nevim jestli to s tim souvisi - v master.cf jsem prepnul smtp aby nebyl
chroot - aby videl na /etc/passwd a mel prehled o uzivatelich. Potom :

local_recipient_maps = $alias_maps unix:passwd.byname

a dale :

smtpd_sender_restrictions = permit_mynetworks, reject_unknown_sender_domain,
                            check_sender_access hash:/etc/postfix/access-global-sender_access

smtpd_recipient_restrictions = permit_mynetworks,
                               check_recipient_access hash:/etc/postfix/access-global-user_divide-DB,
                               check_relay_domains

smtpd_restriction_classes = spamhater,spamfriend

spamhater = check_sender_access hash:/etc/postfix/access-global-sender_access,
            check_client_access hash:/etc/postfix/access-spamhater-client_machines-and-sender_domains,
            check_sender_access hash:/etc/postfix/access-spamhater-client_machines-and-sender_domains,
            reject_unknown_client,
            permit

spamfriend = check_sender_access hash:/etc/postfix/access-global-sender_access,
             check_client_access hash:/etc/postfix/access-spamfriend-client_machines-and-sender_domains,
             check_sender_access hash:/etc/postfix/access-spamfriend-client_machines-and-sender_domains,
             permit

kde soubor /etc/postfix/access-global-user_divide-DB obsahuje trideni
uzivatelu a domen do trid spamhater spamfriend (a nebo nikam) :

bf.jcu.cz              spamhater
rum.bf.jcu.cz          spamhater
tix.bf.jcu.cz          spamhater
petrsi@              spamhater
simek@               spamhater

soubor access-global-sender_access obsahuje nadrazenou databazi odesilatelu

muni.cz                         OK
linux.cz                        OK
gin.cz                          OK

soubor access-spamhater-client_machines-and-sender_domains je vlastni
spamlist obsahujici domeny a IP site  :

sprint-hsd.net               550 Frankly, my dear, I don't give it a spam.
209.26.240                   550 Frankly, my dear, I don't give it a spam.

uvedene priklady jsou samozrejme jen castecny vyrez ze spousty radku :-)
A posila SPAMery do p....e hned v ramci SMTP hlavicky ...
