Hi,

I'm running exim 1.92 on my linux box. I connect to my ISP with PPP
3-4 times a day to check my mailbox which is on another server (ie
I don't use fetchmail).

Here's what I would like to happen:

1) Any mail that is sent from my computer while it's offline should wait
in the queue until a connection is established.

2) Only local users who are listed in a file should be able to send mail
to the outside world.

3) I want to use the same file above to lookup the real email addresses
of local users to rewrite From: lines of outgoing messages.

....

1) used to work, but then I introduced 2) and 3), and now I have a
problem. I'll try to explain what my problem is and how I implemented
2) and 3). I would be really glad if you could make suggestions on all
3 points. For full reference, I'm also including my exim.conf at the
end of this message.

exim -qf is run automatically to flush the queue whenever the PPP link
is up. Like I said, this used to work. But now, sometimes when I send a
message while I'm offline, exim freezes the message saying that there
was a domain look-up failure.

My smarthost router includes the line

route_list = "* smtp.freeserve.net bydns_a"

And my retry configuration is

   # Domain               Error       Retries
   # ------               -----       -------
   *                      *           F,2h,15m; G,16h,2h,1.5; F,4d,8h


If I change this to

   *                       *          F,30d,1d;


I no longer get domain look-up failures, but this time, when I send
a message while I'm online, the message just sits in the queue and I
have to flush the queue manually.

The file is /etc/email-addresses, and it looks like this

local_username1: real_email_address1@???
local_username2: real_email_address2@???

The smarthost router includes a condition:

condition = "${lookup{${local_part:$sender_address}}lsearch{/etc/email-addresses} {yes} {no}}"

This, again, works only sometimes (ie, sometimes a user who is not listed
in the email-addresses file can send an email to the outside world. There
must be something wrong with my condition, but what?

*@@    ${lookup{$1}lsearch{/etc/email-addresses}\
                                        {$value}fail} frF


  At least this one works reliably. But any suggestions welcome.                    


Thanks a lot for reading,

Berkan
