You're right, what I wrote is not very clear.

Exim logs are perfect if I want to extract details about senders, IPs,
receivers, rejects, etc. But if I want to see what is exactly going on
in the real SMTP protocol, I could miss something or I see too much.
E.g. something which is written to logs via "logwrite" doesn't appear on
the "SMTP line".

There are some (rare) circumstances, where I would like to see the
"real" SMTP protocol, e.g. something like this (taken from my old MTA
running under Windows NT):

Wed, 10 Nov 2004 00:26:11 +0100
*** SMTP-User foreign-IP connect

<-- 220 my.mta Exim x.x Wed, 10 Nov 2004 00:26:10 +0100
--> EHLO foreign.mta
<-- 250-my.mta Hello foreign-IP
<-- 250-EXPN
<-- 250-SIZE
<-- 250-ETRN
<-- 250-AUTH CRAM-MD5 LOGIN PLAIN
<-- 250 HELP
--> MAIL FROM:<xyz@???> SIZE=1707
<-- 250 <xyz@???>, sender ok
--> RCPT TO:<mylocalpart@???>
<-- 250 1stname name <mylocalpart@???>
--> DATA
<-- 354 Start mail input, terminate with '<CRLF>.<CRLF>'
<-- 250 1712 bytes received in 0,431 seconds
--> QUIT
<-- 221 foreign.mta closing connection

Thank You, I know about "log_selector" and has customized my exim-logs
already.

Yep, I know ... and I really like the style of Exim. But yes, there are
some situations, where I would prefer to see the exact SMTP
communication. May be there's another tool in the Linux-Toolbox which
could log whats going on on port 25 (no, I don't mean a full network
sniffer).

Anyway, thanks for the advice.
