and I think maybe I've overloaded the machine.
I'm new to this list. I suppose you've talk about what combination is better
for medium traffic of emails before. Can you tell me when? (aprox... I'll try
to search the mailing-list archives).
Anyway, if anyone has any suggestions I'd be grateful. Here is some info about
the machine hosting this mail server.
Thank you very much.
