[courier-users] Alias stop working from one day to another...

[Michelle Konzack]

Helloo *,

I do not understand WHY it does not more work, because before it WAS
working.

I have for my "ITSystems" account an alias file of

***@itsystems.tamay-dxxxn.net: catchall-tdnet.itsystems-abuse
***@itsystems.tamay-dxxxn.net: catchall-tdnet.itsystems-support
dhl-***@itsystems.tamay-dxxxn.net: catchall-tdnet.itsystems-dhl-services

where the first two are still working (since many years).

The third alias has compleately unexpected stoped working since January
2017 after my Server was rebooted.

I run a check and dump with makealiases but there is no error at all.
Also a "courier show all" does not give any output

<19>1 2017-04-13T12:38:19.743227+02:00 mail courieresmtpd - - error,relay=2a00:1450:4010:c07::230,from=<***@gmail.com>,to=<dhl-***@itsystems.tamay-dxxxn.net>: 550 User <dhl-services> unknown

Any hints?

What happens when you send mail directly to <catchall-tdnet.itsystems-dhl-
services@<your local domain>>.

I loged into <mail.tamay-dogan.net> as <michelle.konzack> and send to
test messages with the local part to <localhost> and the mailserver and
both came in without any problems.

Now I am back in GMail and now it start working again.

I do not understand this problem.

The courier aliases config is untouched since beginning of January 2017
and it was working until 2017-01-28 for this particular address. I do
not find any notices in the logs what can happen the "address not found"

Can it be, that sometimes courier get a hickup and lost infos from the
alias table?

Thanks and nice Weekend

Changes to the alias file do not require a server restart. Courier checks
the timestamp on the compiles the alias file, and rereads it when it
changes. The only thing I can think of would be a situation involving
network-mounted file storage, and a temporary, transient problem.
