Zdravim,
pokud Vam prijma postfix spamy, je to tim, ze nemate filtery, cili spam a virovy filtr. Mohu tedy doporucit amavis, spamassassin a clamav. Pokud tohle budete tedy resit, jen pripominam, ze v debianu si pridejte repozitare volatile, coz jsou repozitare, kde jsou aktualni verze softwaru jako je antivir apod, pokud by jste toto neudelal, tak clam vam bude delat potize, je to chybou, ktera je spravena ve verzi prave v volatile repozitarich.
Nyni jste v situaci ze Vam postfix prijme vse az na drobnosti, jako je spatny HELO command apod.Je nutne tedy nastavit omezeni jak na strane postfixu, coz by melo byt v poradku ve Vasich konfiguracich, tak take doplnit o vyse uvedene reseni. Pak by uz spam mel prestat.

Pokud tam tedy neni nic viditelne spatneho. Pokud by vadily moc velke logy, staci postelovat logrotate, pokud pouzivas. U me na Fedore je standard 'weekly', neboli rotace jednou tydne, a nekomprimovane logy. Viz /etc/logrotate*
smtpd_helo_restrictions = permit_mynetworks,
reject_rbl_client sbl-xbl.spamhaus.org,
reject_rbl_client list.dsbl.org,
reject_non_fqdn_hostname,
reject_invalid_hostname,
permit
To spolehlivě odfiltruje značnou část spamu už na vstupu, v LOGu pak bude SERVICE UNVAILABLE.
Toto používám a spamassasin má o 90% méně práce
