i am sending some mail in gmail yahoo but i dont really understand how dkim is failing?
What a coincidence, I don’t either. Maybe follow the instructions an provide some some clues as to what you are doing/seeing/using ??
Read the how to ask for help link above.
pass (domain of matt.xyz.com designates 174.63.31.12 as permitted sender)
Authentication-Results: atlas-production.v2-mail-prod1-bf1.omega.yahoo.com;
dkim=perm_fail header.i=@matt.xyz.com header.s=default arc_overridden_status=NOT_OVERRIDDEN;
spf=pass smtp.mailfrom=matt.xyz.com arc_overridden_status=NOT_OVERRIDDEN;
dmarc=pass(p=NONE) header.from=matt.xyz.com arc_overridden_status=NOT_OVERRIDDEN;
When you say Yahoo always fails you mean that everywhere else works?
yes mike gmail , proton mail i can see dkim spf dmarc pass
Show all headers of a failed Yahoo message. Also did you inject SMTP or HTTP?
this is logs
i will share you my yahoo header
Your DNS record for DKIM is broken, you have spaces in the key string. Other MBPs may have been forgiving and removed the spaces, but Yahoo did not. You need to fix your DKIM DNS record.
Go to Network Tools: DNS,IP,Email and do a DKIM Lookup, it tells you that’s the problem. KumoMTA is not causing this issue.
Thank you mike got dkim issue fixed
