Since yesterday (10-21-2021) i've noticed that a lot of emails, that used to pass, are being rejcted based on the evaluation that the senders ip has been blacklisted. Has anyone else have the same experience?

I recently set up our Sophos XG Firewall, and everything is working beautifully! However, today we've run into an issue with the "Mail Logs" within Protect > Email. Previously we used to be able to go into that tab, and it'd tell us every email…
In UTM, I was able to remove certain SMTP headers from outbound emails, but I can't find the same setting in XG. Can anybody point me in the right direction?
Many thanks
Hey,
what is bothering me a lot is that Greylisting is not working. That feature does help with Spam but it is not helpful when the mails arrive sometimes half-a-day or even 4 days later. Also when any mail goes through exactly that constellation of…

Hi all,
Does anyone have a decent walk-through explaining how to get a server cert onto an XG? I'm in MTA mode but using the appliance CA. I have a GoDaddy cert for my 2016 exchange server and I'm assuming that can be imported somehow, maybe. I see…
Due to new behavior, v17 clients in MTA mode may have trouble receiving and sending emails to servers that don't support a higher TLS protocol than TLS 1.0.
If this affects you, follow our KB Article: Advisory: Sophos XG Firewall email fails to send…
