Dear DA forum,

The auto-responder feature appears not to use DKIM signing, preventing emails from an auto-responder to be delivered to Gmail addresses:
Code: 
/var/log/mail.info:Feb 20 08:43:38 pmg01 relay2/smtp[2385966]: 096B61C26DB: to=<****@gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.23.26]:25, delay=3.7, delays=0.04/0/2.4/1.3, dsn=5.7.26, status=bounced (host gmail-smtp-in.l.google.com[74.125.23.26] said: 550-5.7.26 This mail has been blocked because the sender is unauthenticated. 550-5.7.26 Gmail requires all senders to authenticate with either SPF or DKIM. 550-5.7.26  550-5.7.26  Authentication results: 550-5.7.26  DKIM = did not pass 550-5.7.26  SPF [] with ip: [****] = did not pass 550-5.7.26  550-5.7.26  For instructions on setting up authentication, go to 550 5.7.26  https://support.google.com/mail/answer/81126#authentication p16-20020a17090adf9000b00297131a7502si5865761pjv.164 - gsmtp (in reply to end of DATA command))

I've already stumbled upon these 2 threads, but couldn't fix the issue with the information provided in them:
https://forum.directadmin.com/threads/no-dkim-alignment-vacation-message.58438/
https://forum.directadmin.com/threads/dkim-not-signing-emails-via-auto-responder.66092/

Does anyone know how to configure Exim so that an auto-responder gets DKIM signed?

Thanks in advance & kind regards
 
The solution is here, in case you have a seperate DNS zone for your hostname:

No DKIM alignment vacation message

Good afternoon, I new to this forum. Looking forward for some help. I have this question and I cannot find the answer in the forum. DirectAdmin is up to date. When I create a vacation auto reply the mails are send without any DKIM alignment. So, due to our DMARC policy mails are rejected at...

it's in that thread you linked to.

If you have it other ways or it doesn't work, there was a link in your second link, which provides exactly what you're asking for.

Solved - Mail generated from sieve filters are not DKIM signed

When adding a sieve filter for out-of-office, the automatic email is sent without being DKIM signed. Example: Sieve filter: require ["date","relational","vacation"]; # rule:[Out of Office] if allof (currentdate :zone "+0200" :value "ge" "iso8601" "2021-07-01T16:30:00+02:00", currentdate :zone...

Setup a (SPF) record like this:

server.domain.com. <-- this has to be your full hostname e.g. srv1.domain.com.
3600
TXT
"v=spf1 ip4:YOURIPV4HERE ip6:YOURIPV6HERE ~all"
 
Normally yes. I hope it will be enough because here both SPF and DKIM are checked as you can see in the log line, so there is a chance that the SPF then passes by but it's still blocked because DKIM is false. ;)
