I need to configure a mail server to be able to send more than 60.000 email by hour.
On my dedicate server i installed freebsd and i need to use this OS because this server are also a firewall and web proxy for one big site.
Postfix are already installed.
Just need to optimize and create some mail address.
Each mail box need to have a dedicate IP address.
If are not possible, i need to be able to change the IP and hostname each time i want to or the ip are in black list.
The mail server don't send spam, it send newsletter from a a big forum that use smtp server to send mail.
Please i need someone good.
