Bug#331716: exim4: handling of various system users

[Ross Boylan]

Package: exim4
Version: 4.52-2
Severity: wishlist


[2nd attempt to submit this bug]

Thanks to recent local chaos, the system attempted to deliver some
undeliverable messages to the original sender, logcheck.

/etc/aliases on my system needed
logcheck: root

as an entry.  When I checked, I discovered a signficant, though old,
bunch of mail delivered to /var/spool/mail/logcheck.

There's similar story for cyrus.

I don't know if either matter is properly an exim issue, but this
seemed the best place to report it.

This suggests a more general idea: maybe there should be a router that
sends all messages for users < 1000 to root?  I recall there's some
Debian policy that would allow identification of account type from
uid.

Though I've filed a lot of trivial bugs today, and this one is only
wishlist, I'd say it's a bit important.  Otherwise, people may not
ever see some messages.
