Carbon Copy question

[Nilo Menezes]

I figured out a strange behavior with my little 
server, specially that with an 64K channel.

A user need to send a domn XLS file to 10 other 
people in the other factory unit, so
he puts9 of them in the cc line and one in 
the to line. My question is: qmail is
sending that message 10 times to the same host. I 
can see 10 qmail-remote instances,
running together, delivery the same message 10 
times. It's a 3MB message x 10 = 30 MB
to pass in a 64K channel. It's simply shutdown any 
other connections due to traffic.

Why my mail server don't sent the message only 
once, to ten users in the same domains
at one time ?

I use qmail-1.03 + vpopmail in a Linux small 
server.

This behaviour is intentional.

 A user need to send a domn XLS file to 10 other people in the other factory unit,

One solution is to create an expansion alias at the other end of the line 
and address to that alias. Another one is to use serialmail with some sort 
of duplicates recognition (Russell Nelson has a script that does that for 
one user).

The simplest solution in your case may be to use Postfix instead. Qmail is 
not perfect in every infrastructure.
