Yes, get the email addresses right.

Exim HAS to reject the invalid address. Then your mail client is faced with 
the problem of communicating to you what is going wrong, and guessing 
whether you want to fix the problem before or after sending the mail to the 
other recipients.

The easiest thing for the mail client to do is hang on to the email until 
you've either:

RE: forward an deliver to mailbox at the same time

Hi.

In this case Exim's intrinsic loop detection and avoidance will just
skip the router that produced loop. The adrress `foo' does make loop, so
the userforward router will be skipped, probably giving `Unroutable
address' response.

Sure it's possible at Exim level. The `unseen' generic router option is
your choice. Make two adjacent routers, one `driver = redirect' and one

max amount of parallel deliveries

Hello,

i want to know if there is any possibility (which maybe i didnt found in 
the specs) to limit the amount of parallel deliveries via a pipe transport.
The problem is that under some circumstances the OS cant deal with such a 
high process count very well, without affecting the load of the system 
itself.
For example File Descriptors or a not fast enough handling of all 
deliveries which will end in constand increasing processcount and a memory 
problem...

'421 lost input connection' error.

In the archives there's a message from Jirí Smejkal
(http://www.exim.org/mailman/htdig/exim-users/Week-of-Mon-20040823/msg00090.
html) that seems to describe exactly the problem I am experiencing. Has
anyone discovered the cause or had any further thoughts on the problem?

I'm using Exim 4.43 with the Exiscan patch and PostgreSQL 7.4.6, all
compiled from sources on FreeBSD 5.1. On connecting to Exim on TCP port 25
(or even on stdin using the -bh option) Exim emits the welcome banner and
then immediately closes the connection with the message '421 <hostname> lost
input connection'.

Example output from 'exim -d -bh 127.0.0.1':

host in host_reject_connection? no (option unset)
host in sender_unqualified_hosts? no (option unset)
host in recipient_unqualified_hosts? no (option unset)

How can I force non-local delivery for one user?

Hello,

I've been reading the exim docs trying to find a solution for this 
problem. Perhaps someone can help me.

We're running exim with local delivery to unix-style mailboxes with all 
other mail being sent to a smarthost. We run fetchmail every 20 minutes 
to download from the same smarthost, and qpopper to interface with 
users' mail clients. It's all fairly standard stuff.

However, we also have one user that is out of the office fairly 
regularly (call him Bob), and he needs to be able to access his email no 
matter where he is. The solution we've been using so far is quite simple:

  * never run fetchmail for bob (all mail stored on smarthost)

  * bob's mail client receives from both servers, but
    sends via smarthost

  * when bob is out of the office, everyone changes their smtp mail
    config to talk directly to the smarthost

I'd like to get away from the situation where everyone has to keep 
changing their mail configurations. What I want to do with exim is set 
it up so that whenever there's mail for bob, it gets sent directly to 
the smarthost instead of being delivered locally.

My exim version is 3.36 running on a Debian box.

Thanks,

More embedded Perl functionality


  Hi.  I've got a few items for the WishList.

  First off, I'd like to be able to process the whole message inside the
 embedded Perl functions.  I'm happy with it being some read-only
 variable or file handle (or even an intrinsic Exim variable that can
 be passed along as a parameter), just so that I can actually do spam
 filtering and return a string fit for headers_add or something.

  Secondly, I'd like to have a "perl" transport.  No, really, I'm being
 serious.  :)  Often, I find myself ending up writing custom MDAs, as I
 need to update some quota counter in a database or whatever, which
 rarely is possible to do properly within Exim itself.  But it could
 easily be done within Exim's embedded Perl, which would make all of my
 home-made external MDAs superfluous.  For example:

    localstore:
      driver = perl
      return_path_add = true
      perlsub = deliver_localstore $local_part $message_size

  and the deliver_localstore() function got $local_part and
 $message_size as $_[0] and $_[1] and was then responsible for updating
 the quota counter, saving the message (found in <MESSAGE> or wherever,
 according to wish #1) to disk somewhere, fsync'ing, and return 0 if
 everything went fine.

  I wonder how hard it would be to implement something like this?  :)

Kind regards,

Massive eBay Dupe Flood

Hi All,

I'm trying to figure out why folks at our site are getting massive
amounts of duplicate mail from eBay.  The mail seems to be isolated
that which is generated by an automated process, for example,
end-of-auction e-mails and customer service automated responses.  We
are getting the same messages delivered every five or ten minutes or
so.  The logs show nothing unusual except duplicate Message IDs:

(recipient e-mail address changed to protect the innocent)

about the issue.  Five hundred messages later, I wish I never
complained in the first place. :)

Not directly. See the discussion of the remote_max_parallel option about
using queue_only and queue_run_max.

Exiscan + Spamassassin. SpamAssassin is a Perl solution with plug-in
capabilities:

http://www.spamassassin.org
http://duncanthrax.net/exiscan-acl

You'll find everything about spam/headers/etc there.
