[RCU] RCM appears to be the culprit for non-delivery of some emails to GMail addresses

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?
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.
