Hallo Peter,
danke für deine überaus schnelle Antwort und deinen Tipp.
Hier ein Mail, das ich zurückbekommen habe: (habe meine Mail unkenntlich gemacht)
nach meiner Einschätzung sendet irgend ein Bot nicht via meinem Mailserver oder Nas, sondern einfach in meinem Namen, bzw. meiner Domain.
Wie kann ich denn das unterbinden?
Ich kann ja schlecht mit einem Filter einfach alle Mails mit dem Titel: "Mail Delivery System" in den Spamordner kicken. Dann würde ich ja nicht mehr sehen wenn meine eigenen Mails nicht mehr ankommen...
A message from <joel@xxxxxxxx.ch>
(meine Mailadresse)
to:
xxxxxx@vscht.cz
to:
yyyyy@vscht.cz
to:
zzzzz@vscht.cz
was considered unsolicited bulk e-mail (UBE).
Our internal reference code for your message is 05240-11/M72p1HuclNDW
The message carried your return address, so it was either a genuine mail
from you, or a sender address was faked and your e-mail address abused
by third party, in which case we apologize for undesired notification.
We do try to minimize backscatter for more prominent cases of UBE and
for infected mail, but for less obvious cases some balance between
losing genuine mail and sending undesired backscatter is sought,
and there can be some collateral damage on either side.
First upstream SMTP client IP address: [147.yy.xx.z]
(nicht meine IP) ns.vscht.cz
According to a 'Received:' trace, the message apparently originated at:
[147.yy.xx.z],

From: "aaaaaa@vscht.cz" <joel@xxxxxxxx.ch>
