[exim] SMTP timeouts and retry database

Hi all.

I have a problem regarding TCP timeouts on outgoing SMTP connections
and the retry database. Looking around revealed this message from
this list back in 2004 which describes the exact problem I am seeing:

The exim version is the default RHEL4 version, so it's a little oldish
(based on 4.43).

Has this bug been fixed in a more recent version? Looking through the
changelogs showed nothing definite.

Thanks.
