Hello,

I would like to be able to configure my instance of postfix so that
messages to domains I have trouble reaching from my DSL line, would be
relayed through my ISP's mail server.

How can I configure postifx to be an smtp client for these domains? I
have these domains in a flat file where each domain is on a new line.

I have read
http://www.postfix.org/postconf.5.html#smtp_fallback_relay
but I am not sure how to implement it or if it is the function I need for this.

Many thanks for your help!
