Re: Sending with Multiple Domain Suffixes from Single Apache Server Box

Umm forget what i said about transport. check this out http://www.postfix.org/ADDRESS_REWRITING_README.html This sounds like your idea : Replace an internal address by an external address. For example, replace "username@localdomain.local" by "isp-account@isp.example" when sending mail

OpenDKIM on backup MX

Hello friends, On Debian Jessie I would like to enable OpenDKIM on my two Postfix servers. My question is how to behave with the secondary backup server. Enable it as on the first and then I copy the key from first to secondary? And how I will write DNS txt record that must take the two
