Pkg exim4 users - Sep 2008 - Bounces, errors and how to configure it

Hi,

I have a problem with my exim configuration and I really don''t know how
to
solve it. I have a little network at home with a old box acting as a mail 
server. This box is running a etch.

My mail server, use another box (from a friend) as a smtp, because my ISP 
doesn''t have a good smtp server and in many places doesn''t
accept mails from
dynamic IPs.

The mail server recollect the mail from me and my wife using fetchmail and 
delivers it to exim who pass it to spanassassin. My configuration works in 
general, but some times I got some troubles and I don''t know how to
solve it.

For example, if spamassassin is too busy, then, fetchmail couldn''t
delivery
the mail, so, generate a bounce that is sent to the smtp of my friend, and I 
don''t want it. I would like that the bounce or the errors goes to my 
postmaster at localhost.

Also, some times I have a problem with the smtp and it rejects to resend a 
mail and I got an error. However, I don''t know how to send this error
to the
user that try to send a message. Neither to postmaster.

I have modified the   /etc/exim4/conf.d/main/02_exim4-config_options  file, 
adding:


errors_reply_to = postmaster at localhost


MAIN_FREEZE_TELL = postmaster at localhost
.endif
freeze_tell = MAIN_FREEZE_TELL


However, this options doesn''t do the job, and I really have no idea how
to
solve it. Also, I''m very comfortable with the debian way of do the
things.
But, with exim, I doesn''t understand how they work.

The idea is to modify the update-exim4.conf.conf and after run 
update-exim4.conf, no? And how can I incorporate options not in the dc_XXX 
vars?

Regards,

Thank''s in advance.

Leo

I assume you are running spamassassin at SMTP time (using the spam
=... ACLs)? This looks like the wrong thing to do in your use case
since you *never* want to reject mail at SMTP time because this would
only upset fetchmail.

Running spamassassin when delivering or as a transport filter should
work better, in that case fetchmail does not need to wait (timeout)
for spamassassin to run.

The bounce is always sent to the (envelope sender).

The idea is to
a) edit /etc/exim4/exim4.conf.localmacros
for stuff whith predifined hooks, e.g. to override trusted_users uucp by defing
MAIN_TRUSTED_USERS.

b) directly edit the dpkg-conffile /etc/exim4/exim4.conf.template (or
the split up version) otherwise.

Of course there is a point where it is better and simpler to ignore
the Debian configuration and simply manually build a
/etc/exim4/exim4.conf.

I''m running spamassassin in the transport part (I guess ..) I have a:
/etc/exim4/conf.d/transport/30_exim4-config_spamcheck file with:

spamcheck:
  debug_print = "T: spamassassin_pipe for $local_part@$domain"
  driver = pipe
  command = /usr/sbin/exim4 -oMr spam-scanned -bS -d+transport
  use_bsmtp
  transport_filter = /usr/bin/spamc #-u ${local_part}
  home_directory = "/tmp"
  current_directory = "/tmp"
  user = Debian-exim
  group = Debian-exim
  return_fail_output
  message_prefix   message_suffix   temp_errors = *

and a:
/etc/exim4/conf.d/router/850_exim4-config_spamcheck_router

with:
spamcheck_router:
  no_verify
  check_local_user
  # When to scan a message :
  #   -   it isn''t already flagged as spam
  #   -   it isn''t already scanned
  condition = "${if and { {!def:h_X-Spam-Flag:} {!eq {$received_protocol}
{spam-scanned}}} {1}{0}}"
  driver = accept
  transport = spamcheck

Not sure, or I don''t know what''s happen. The sender is
fetchmail.

I don''t have this file /etc/exim4/exim4.conf.localmacros ... ?

Ok,

Thanks,

I will try to monitorize some days to try to find something about it.
