Hi! I am administering server running courier 0.41 connected to the Internet via "thin" line. This line is overloaded all the time due to the heavy traffic generated by multirecipient mails. People in organization, owning the server, are sending _really_big_ mails (with fotos, included docs etc.) to many clients, i.e. they are adding several "to" lines to the header. I've tried to resolve the problem by adding line ":some.host.on.very.wide.channel" to the esmtproutes, but it didn't help. Courier is still sending the copy of message per every recipient to that server instead of sending one message with multiple "to" lines. I can't just change "outgoing SMTP" setting in user's mail clients because in that case all local traffic (even heavier, than external) will be redirected to the external server. So, the question is: how to force courier to forward multirecipient mails to external server as one mail with multiple "to" (bcc, cc) lines ? Thanks for help.
