Hi list.
My incoming messages are getting R_SPF_DNSFAIL and an error on the Authentication-Results header:
spf=temperror (mail01.r3pek.org: error in processing during lookup of no-reply@cttexpresso.pt: DNS error)
I see the DNS request on my DNS server and a "working" reply going out. What can cause this error and/or how can I debug it?
How (which program) is the SPF check being done?
Dovecot doesn't do that (AFAIK anyway), so maybe you want to check which program (e.g. a postfix milter, such as rspamd) is doing that and check the logs of that program to see what went wrong.
But I'm 99.9% sure this has nothing to do with dovecot :)
