When receiving emails from Elkarte it fails on the SPF check and ends up in the Spam folder for me.
Looking up the SPF record it has the following;
I think it needs to be updated to have the other domain/IP in it's configuration so that's also allowed. As the IP resolves to s2.eurich.de not s3.eurich.de
Well, interesting! Thanks for the report.
The existing SPF record simply had MX and A records as allowed to send. I'm guessing when
@TE setup the new server he chose to use the old servers mail so he did not have to enjoy the fun associated with a new IP address and mail reputation. I just went through this and it took weeks to get a the new IP address clear even though it was all SPF/DMARC/DKIM/RDNS/Virus scan valid mail.
So I've added s2.eurich.de as a designated sender (in addition to the current mx / a which point at s3.) I could probably just point the mx record to s2.eurich.de ip address, but this should work fine.
v=spf1 a mx a:s2.eurich.de ~all
I just gave it a quick test and it seems to give an spf:pass result now
