Hi,

Something seems off, and I would not suspect RC as the first culprit:

• PEBKAC: if the receiver has set up rules to move certain emails to a

folder that (s)he didn't check

• PEBKAC: if the email is in a junkmail folder that wasn't checked
• Qmail bug? Maybe increase log level?
• Other bug? At my wife's office, we hit an Evolution bug last year that

was known for many years, but apparently nobody cared enough to fix it until we were hit - the client reported that sending had succeeded, but exim never actually sent the email...

In general, I don't believe Gmail would reject email and not warn either the sender or the recipient. Did you try the Gmail support form? https://support.google.com/mail/troubleshooter/2920052?hl=en

If you want, I can give you my gmail.com address (off-list) so you can send a few testmails to me. I have 0 mail rules set up and know how to check a junkmail folder, so if that can help you solve the issue, I'd be more than happy to report to you what I did and did not receive.

People,

This is my setup:

Fedora 28 x86_64 workstation + Firefox <=> Fedora 26 x86_64 Server + RCM + QMail + multiple domains <=> Internet

I have multiple email addresses for the multiple domains I run web sites and mailing lists for - last night when I mailed to someone from phr AT philiprhoades DOT org to a their GMail address - the mail was not delivered. I went through a bit of debugging with the recipient today and what I know so far is:

• If I use RCM and the phr email address to send mail - even though

the QMail logs say that the mail was successfully delivered - it never actually arrives - BUT no bounce message is ever received either.

• If I use swaks on the server to send a test email from the phr

address to the same person, it is delivered OK.

• If I use qmail-inject on the server to send the original email that

failed from its Maildir Sent dir to the same person, it is delivered OK.

So it looks like something that RCM is adding to the headers is being objected to by the GMail servers or something - of course since nothing is ever actually delivered or bounced, I can't compare the header lines of the failed emails to the successful emails so I can't make any more progress trying to work out what the problem is.

I have occasionally had rDNS issues but my diagnostics don't seem to fit that non-delivery issue . . anyone got any ideas? Is it possible that GMail servers can successfully accept emails but then silently fail to deliver them to recipients?

Thanks,

Phil.

This is simply not true.  Gmail absolutely drops mail after accepting it from my server.  Worse, it appears to be completely random so most of the time e-mail that Gmail accepts is delivered. My hunch is that different servers in their mail pool are configured slightly differently or their internal routing after delivery is wonky.  I have RC installed but only one client of mine actually uses it, so I don't think this is a RC problem either.

Good luck with getting any support from Gmail.  You get what you pay for with a gmail account.
