I seems to occur once per each message which is delivered to remote --
when only local deliveries happen, no errors appear.
For messages with remote targets this is repeateble.

Bullshit!!! Someone made these files root-owned. Who, I wonder.
When I killed them, new ones appeared:

And errors are gone!

But where have they appeared from?...
Maybe it helps: at about November 8 the distribution (most likely) was
Debian popato, so exim version was about 3.12.

It seems that there was some bug with uid/gid changing...
Perhaps this is the same thing people get with "-qff".
