Under 'Configuring Sender-Dependent SASL authentication', it says: Likewise, the Postfix trivial-rewrite(8) daemon will search the per-sender relayhost file, and use the default relayhost setting only as a final resort.
Would it be clearer to say "per-sender sender_dependent_relayhost_maps file" maybe? Or at the very least refer to / mention the correct configuration parameter, sender_dependent_relayhost_maps (maybe in brackets after "per-sender relayhost file"), so that it's clearer. -jf -- He who settles on the idea of the intelligent man as a static entity only shows himself to be a fool.
