[imp] IMP logging (plus strange problem on a two-server system)

[Giuseppe Sollazzo]

Hi there,

I would like to know if there's a way to log all IMP attempt to send 
mail via smtp server.


I have the following problem: I have 2 servers A and B.
I installed the HORDE/IMP framework on A, configured (but not tested) 
it, then I made a tar.gz of the whole installation and copied it to 
server B (including the configuration file).

I have all in /var/www/html/horde, same httpd.conf, same rights on 
files. On both systems, the smtp server is on localhost.

Well, the simple problem is that on server B it works properly, on 
server A it doesn't. No error messages at all, but e-mail are not 
delivered to any domain when I use IMP on server A. [It sounds weird: I 
simply copied the configuration FROM server A TO server B and the latter 
is the only working?]

Furthermore: squirrelmail, my old system, keeps working on both servers; 
also smtp via telnet works fine.

What could be the mistake?

This is why I'm looking for IMP logs... can you help me this or another way?

Regards,
Beppe
