Hi Thanks for the info, running command xxx gives me v2.10-20120422, would I be correct I cant use "sender_dependent_relayhost_maps" as this needs v2.3 or later?
However I see the date is 20120422 and wiki says the release is v2.10 so how do I read these versions?

(as relayhost has no entry in the main.cf) Your question is answered (really) by the sender_dependent_relayhost_maps documentation. http://www.postfix.org/postconf.5.html#sender_dependent_relayhost_maps > How do I get the version number of the postfix service (under Ubuntu 10). postconf | grep version > I am using Zimbra, it seems they load there own version of postfix as > its not in the default location. They change a lot more. You may want to check that yor modifications won't break their support. Wietse
