We highly discourage email autoforwarding because it may fail due to SPF/DKIM/DMARC issues and because our mailserver gets blamed for any forwarded spam and may be blacklisted. Also to be honest, these issues have become more complicated than I can afford to study and understand, but I know there are often problems with list servers unless the reply addresses and header rewriting are carefully configured. The problem being that mail is now coming from a different mailserver than the one authorized to send mail for the originator's domain.
Is it possible you are running into this kind of problem? Are all emails disappearing on the way to Gmail, or does it depend on the sender? -----Original Message----- From: Blueonyx <blueonyx-boun...@mail.blueonyx.it> On Behalf Of Michael Stauber Sent: Saturday, March 16, 2019 2:42 AM To: blueonyx@mail.blueonyx.it Subject: [BlueOnyx:22776] Re: Email Forwarding not working Hi Felix, > How can I troubleshoot this issue of disappearing emails?

It should show you if that the vacation messages were sent and what the response from Google was. Additionally for testing edit /usr/local/sbin/vacation.pl and find this line: # Debugging switch: $DEBUG = "0"; Change the value to "1" instead: $DEBUG = "1"; Then run "tail -f /var/log/maillog" and send an email to the user in question. The maillog will then also contain debugging info from the vacation message script. -- With best regards Michael Stauber _______________________________________________ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx _______________________________________________ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx
