[exim] Out of office solutions

Hi list,

can anyone advise me on ways to implement an out of office solution on exim,
where exim is being used as a POP3/SMTP mail system?
I imagine I need a web front end to allow users to select if they are in or out of
office and a simple rule in the exim config, are there any existing opensource
web front ends for this type of requirement kicking around? Or in general what
would those experienced with exim recommend me?

thanks for any info! cheers Andy.From hs@??? Wed Mar 05 12:40:39 2008

Hello,

probably I'm too stupid....

There's an part in the acl (check_smtp_mail) checking the sender ip
against some dns blacklists. Unfortunely "dynablock.njabl.org" doesn't
seem to respond.

If I understood well (from searching the archives) exim just uses the
resolvers timeout:

    <~  250-AUTH PLAIN LOGIN
    <~  250 HELP
     ~> MAIL FROM:<>
    === response in 52.183s
    <~  250 OK
     ~> RCPT TO:<heiko@???>
    === response in 0.090s
    <~  250 Accepted
     ~> DATA

I'd like to cut down this timeout and specify a default action
(here: accept).

But I do not see any possibility.

Any ideas or hints?

    Best regards from Dresden
