Samuel Heinrich

we are currently seeing high amounts of false positive blacklist hits, although none of the IPs is actually blacklisted.

SFOS 18.0.4 MR-4

here are a few examples, of IPs which not blacklisted but got rejected.

194.56.219.38

194.56.219.33

94.100.136.174

83.144.254.184

2021-10-14 11:53:51.020 [31787] H=smtp2.iwb.ch (iwb10.iwb.ch) [194.56.219.38]:36248 I=[x.x.x.x]:25 X=TLS1.2:ECDHE-RSA-AES256-GCM-SHA384:256 CV=no F=<xxxx@xxx> rejected RCPT <jonathan.kunz@xxxxxx Sophos Anti Spam Engine has blocked this Email because the sender IP Address is blacklisted.

    Hello

    With which command and did you display the log?

    I have the same problem, but my customer wants me to send him a printout so he can see what he missed.

    And via the log view each e-mail has been delivered. Which is totally inconsistent, because under email logs many emails have been rejected because of anti-spam.

    Greetings
