SPF Check not working on UTM 9

NewCom23 over 3 years ago

Sophos UTM 9 Version 9.705-3

We had yesterday an Phishing Mail attack with pishing mails, that were sent from a fake address with our own domain.

They were sent from random hosting servers and were not blocked by the SPF check. Even though this servers aren't permitted over the SPF entry.

This thread was automatically locked due to age.

There is no exception for our domain and synchronization@ is also an invalid address.
