Dear Support,
Our VM server has two network interfaces installed, ens160 and ens192.
Postfix randomly chooses the interface to send outgoing emails.
We would like to send outgoing emails only from ens160, can you please advise how to do it?

Thank you

Re: Multiple IP addresses, send emails only from one

Update Postfix main.cf, bind the IP to one of them.
FYI: http://www.postfix.org/postconf.5.html# … nd_address
