DKIM/SPF Disposition: fail
by mfoley from LinuxQuestions.org on (#6EBHD)
My mail server (static, business IP) has a DKIM record:
Code:$ dig +short TXT novatec._domainkey.novatec-inc.com
"v=DKIM1; k=rsa; p=MIGfMA0GCSqGSIb3DQE ...and SPF record:
Code:$ dig +short novatec-inc.com txt
"v=spf1 mx a ip4:24.142.169.12/32 ip6:2603:6011:2d02:ee82:f66d:4ff:fe5f:ffd1 ~all"
"google-site-verification=8pUMKzGWw5oxZSgjy1VO3yXb2-z5lDfREHje8YNlCr0"
"spectrum-siteverification=f1b3d94c-a619-42d6-98bc-f7ccc33d2c4c"When I send emails from this server to e.g. gmail, it works fine; my DMARC notices show DKIM Results: pass and SPF Results: pass. However, when I send email from my home computer using Thunderbird and the novatec-inc.com server as the relay, I get the following:

I think the messages are getting delivered, but with gmail, that may change.
I send quite a lot of email from my home computer connecting with POP via the mail server at novatec-inc.com. I'm sure many people send email from home computers or cell phones connecting to their work computers to so so.
Am I doing something wrong to get the "fail" dispositions? How can I fix this?
