Hi

Thanks, I did see this info, however am hoping to find someone who has used
this before, its not clear what happens when the FROM address isn't listed
in the " sender_dependent_relayhost_maps" does it then try to send END to
END? (as relayhost has no entry in the main.cf)

How do I get the version number of the postfix service (under Ubuntu 10).

I am using Zimbra, it seems they load there own version of postfix as its
not in the default location.

Many Thanks
Ashley

based on FROM address (possible?)

Acording to this :
       smtp_sasl_password_maps (empty)
              Optional Postfix SMTP client lookup tables with one
              username:password  entry  per  remote  hostname  or
              domain, or  sender  address  when  sender-dependent
              authentication is enabled.

http://www.postfix.org/postconf.5.html#smtp_sender_dependent_authentication

smtp_sender_dependent_authentication (default: no) Enable sender-dependent
authentication in the Postfix SMTP client; this is available only with SASL
authentication, and disables SMTP connection caching to ensure that mail
from different senders will use the appropriate credentials.
