Jemand versucht mir eine Mail zu senden (debian 6, standard postfix/dovecote configs, keine configs verändert), und sagte mir, dass diese mit einem Error an ihm zurück kammen.
Darauf hin habe ich die Logs geprüft und folgendes gefunden:
Code

Die Frage die sich mir stellt, wieso wird die Mail geblockt?
Ist doch weder in NOT_IN_SBL_XBL_SPAMHAUS=-1.5 NOT_IN_SPAMCOP=-1.5 NOT_IN_BL_NJABL=-1.5
