Dear all
I am having quite a strange behaviour with my UTM 9 (fully up-to-date Formare 9.509-3). It started a few weeks ago (can pinpoint the exact time) that certain messages were being quarantined even though they seemed to be ok (Having a 100kB unencrypted PDF attached). I just realised that the link between those was that the messages have a .dat Attachement that contains a pgp signature. I can reproduce the problem on my system by attaching the dat file to an email and send it to me. The message gets moved to quarantine. Does anybody have the same problem or know a workaround (other than disabling the quarantine for unscannable mails / attachements)?
Typical log entry:
2018:05:03-10:50:33 mailgateway smtpd[13870]: SCANNER[13870]: id="1001" severity="info" sys="SecureMail" sub="smtp" name="email quarantined" srcip="xxxx.xxx.xxxx.xxxx" from="redacted@domain.com" to="redacted@domain.com" subject="test" queueid="1fE9wf-0003bi-5h" size="1776" reason="unscannable" extra="Encrypted archive"
