We have several incoming gateways.

Gateway 1 (mx1.domain.com) is 192.168.1.10

Smartermail server 192.168.1.20

In smartermail we have under antispam/IP bypass 192.168.1.10 with bypass spam check and bypass greylisting checked.

The spam log says this:

[2020.07.29] 17:12:09.379 [01046] Running SPF check [2020.07.29] 17:12:09.379 [01047] SPF SoftFail. IP: 192.168.1.10, Sender: heimire@gmail.com, FailReason: [2020.07.29]     SPF Record: v=spf1 redirect=_spf.google.com [2020.07.29] 17:12:09.379 [01047] Finished SPF check; result = SoftFail [2020.07.29] 17:12:09.379 [01047] [DKIM] Performing DKIM check...

So its still checking the gateway it seems.

IP addresses are just made up.

Any idea what Im doing wrong here?
