Hello.
I have one server with qmail, daemontools, ucspi-tcp, qmailanalog.
Server have 10 ip address.
Server OS is RedHat EL 3.0.
My problem - ever 10 minutes and after send 10000 mails change ip address what appear in mail headers (outgoing ip address).

I will run a crond script who will do it every 10 minutes, and another script - for calculate current number of send e-mails.

The main question - how make changing of outgoing ip address.

Thanks.
