I saw the description of the variable nonetheless I was asking if is it only
useful in case of a backup mail exchange.
If your question is really
"I'm not a backup MX. Will anything bad happen if I don't set
proxy_interfaces?"
then the answer is "probably not".
But go ahead and set it anyway. Postfix expects to know the
external IP address and there isn't any reason to keep it
secret from postfix.
One other thing this setting does is enable mail to
[EMAIL PROTECTED] which is a required but seldom used
support address.
