Topic: Force iRedMail to use a specific IP

==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====

I have two Public IP's. I want to force iRedMail to use only one IP. The other I am going to use for the webserver. I have put the IP I want to use into main.cf and restarted postfix. but when I log into iRedMail it shows me both IPs. How do I force it to just use one?

Re: Force iRedMail to use a specific IP

Did you update parameter "inet_interfaces" in Postfix main.cf?

You may want to check smtp_bind_address and smtp_bind_address6 also:
http://www.postfix.org/postconf.5.html# … nd_address
http://www.postfix.org/postconf.5.html# … d_address6

Re: Force iRedMail to use a specific IP

But since SMTP/IMAP/POP3 doesn't use port 80/443 (http/https), there's no need to do such separation i guess.
