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.
2021-10-14 11:53:51.020  H=smtp2.iwb.ch (iwb10.iwb.ch) [126.96.36.199]: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.
any one else ?
Update: it seems that the issue is resolved since around 1'o clock
I looks like it was the same issue as with the UTM plattform.
