Hi,
Should Sender Rewriting Scheme be enabled for a server acting as backup MX. Just to be specific I want one of my servers to solely act as a backup MX for the domain. My understanding is SRS is needed if the mail server acts as forwarder. But in the case of a backup MX it is not a forwarder. (or is it ?) Postfix documentation regarding Backup MX doesn't mention anything about this http://www.postfix.org/STANDARD_CONFIGURATION_README.html#backup and the address rewriting documentation also doesn't mention such a thing http://www.postfix.org/ADDRESS_REWRITING_README.html or am I not seeing it? Thanks
