Hello. I am a little bit confused, and dunne where to dig
I have some users and they (not always) complains that mails they had sent bounced back
First I have this log on Proxmox v8.0.1
and immediately after that a user receives mail from postmaster thet is pointed in my SPF record
I have the rule Rule: Block outgoing Spam and Spam level was 3 before I raised to 5.
I immediately sending mails from the OWA and mails are delivered to recipient. I take remote control of a computer - mail not sent from offline client.
Strange. But after some time, User can send and receive mails using offline client...
Have u ever faced with this kind of behavior....
