Change Exim Sending IP

If you want everyone on the server to send out on the same IP, just add the following to


# nano /etc/mailips:
*: xxx.xxx.xxx.xxx

Then add the IP and it’s matching PTR to /etc/mail_reverse_dns:

# nano /etc/mail_reverse_dns
# xxx.xxx.xxx.xxx hostname.tld

This will tell Exim to use that IP for any sender on the server.

Restart exim

# service exim restart
