#449076 Wer verschickt Spam in unserem Namen? (pc.security)

verfaßt von DomiAleman zur Homepage von DomiAleman, Holdorf, 13.10.2021, 08:45:41

Moin..
wir bekommen seit ein paar Tagen Mails als "unzustellbar" zurück, die wir eigentlich nicht verschickt haben.

Kann man anhand des zurückgesendeten Quelltextes sagen, von wo aus die ursprünglichen Mails versendet werden?

(In den Logfiles unseres Exchange Servers tauchen keine solchen Mails auf.)
Server.PMHOLDORF.local ist unser lokaler Mailserver.
die Domain "cebora.de" ist unsere.
Der Mailversand aus unserem Exchange Server heraus findet NICHT über smtp.strato.de statt, sondern über ein ewe mailrelais.
Danke für Tipps..
DoMi
