And it doesn't take any messages any more _at_ _all_? Or does the log
just show some connection being rejected?

Are you aware of the exiwhat utility?

Looks like some delivery processes get stuck doing things, eventually
tripping a connection or a load limit. exiwhat will probably help in
finding out what happens.

You might also try locally delivering a message by piping it into
"/usr/sbin/exim4 -d recipient at domain.example" and judging from the
debug output where the process gets stuck.
