Hi, Wouldn't DKIM signing the OOF messages help? That way the authentication at gmail's side would not fail.

No. If you use MAIL FROM: <>, the SPF doesn't work for MAIL FROM. It will use the SPF (TXT) record for the domain name of the sending SMTP server. If that mail gets out by mail.example.org, mail.example.org will be used for SPF, so TXT record for mail.example.org will be checked. Make sure all outgoing SMTP servers have SPF TXT records for their domains. -- Gruß Marco Send unsolicited bulk mail to 1723725335mu...@cartoonies.org _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
