Postfix: send mails on Virtual IP

« on: May 09, 2018, 11:13:14 am »

Hi There,

How can we get postfix to work with Virtual IPs?
We have added the VIP as "Listening IP" in the postfix config.
Postfix is receiving mail on this IP but when sending it takes the real interface IP nonetheless.
We use OpnSense 18.1.7_1.

Best Regards

This would mean we need 4 new fields, smtp_bind_address and smtpd_bind_address and also for v6.
Should be fairly easy ...
