Heh, I blame this on too much work (and not playing with Exim for a while)
;P That did it - can't believe I didn't think of that.
deny message = No such account <${local_part}@${domain}>
domains = +treat_as_local
!condition = ${lookup {${local_part}@${domain}} dbmnz
{/etc/exim.acct.db} {${if eq {$value}{1} {yes}{no}}}}
delay = ${eval:$rcpt_fail_count * 5}s
accept domains = +treat_as_local
Still, it's too bad I can't trigger delay on a false - using endpass was a
prettier piece of code and it made me feel a bit better at night knowing
that if for whatever reason a lookup failed, Exim would instead just not
accept the recipient - now with the quite naked accept after this deny,
should the deny suffer any baddies, the accept will take the recipient when
I'd rather not :(
If I were to make a patch for Exim that could allow delays on a failure of
conditions as well, what sort of syntax would people feel most comfortable
with? I personally would like this ability and have no problems making a
patch to do it, I just need to know how it should look in the config file.
Philip, what's your feeling towards this?
Eli.
