I am looking for something very basic and nothing too fancy.
I have Postfix and Interspire installed. I just need to change my IP address and out-going email address whenever I send out campaigns.
Secondly, I know its possible to shift IP addresses per x amount of emails sent.
These are my two options.
If you can show me show I can make the changes to Postfix to select different IP and email addresses that would be great. If you can install a script to do it, this will be even better.
Please advise cost
