Hi all!
Exim 4.94
I have trouble with autoreply transport (and any email from Exim-self)
in check DMARK when Exim send bounce/autoreply messages to google.
I want to configure vacation-router. SPF, DKIM, PTR is configured for my
server. When I send email from myself google receives it and pass DKIM,
SPF, DMARK.
When exim send autoreply message to google, google answer:
user@??? R=dnslookup T=remote_smtp H=gmail-smtp-in.l.google.com
[108.177.126.26]
X=TLS1.3:ECDHE_X25519__ECDSA_SECP256R1_SHA256__AES_256_GCM:256 CV=yes:
SMTP error from remote mail server after pipelined end of data:
550-5.7.26 Unauthenticated email from domain.com is not accepted due to
550-5.7.26 domain's DMARC policy. Please contact the administrator of
550-5.7.26 domain.com domain if this was a legitimate mail. Please visit
550-5.7.26
https://support.google.com/mail/answer/2451690 to learn about
the 550 5.7.26 DMARC initiative.
I run exim in debug mode and saw next:

I've read several articles about it. And I understood that empty field
mail-from is normal for bounce-messages. But how resolve problem with
google and other?
Thanks in advance!
