bin jetzt per abuse meldung kontaktiert worden dass einer meiner server spam verschickt. soweit auch korrekt laut logs. hab mir das genauer angesehen und finde einfach das Problem nicht. Auth geht über SASL2 "plain login", alle Relaychecker im Web bestätigen mir dass es kein Openrelay ist. In den Logs find ich auch keine einzige SASL zeile, weshalb die irgendwie anders sich authen müssen dass postfix den spam verschickt.
Bin langsam ziemlich ratlos. habt ihr irgendwelche ideen?
Hier auszüge aus ein paar configs
