/etc/postfix/ispcp/transport overwritten when new user added

[ckalley]

Got a problem, which is probably fairly trivial, but I couldn't find an answer in the FAQ or searching the forums.

We've started using a IspCP server at work, and we need to set certains domains (such as AOL) to relay though another server on our network. So I add the relay into /etc/ispcp/transport

aol.com relay: mx.somedomain.com

postmap hash:/etc/postfix/ispcp/transport
postfix reload

and that works fine, until a new user is added via the control panel, then the transport file is set back to blank. I'm assuming it's pulling the details for the file from somewhere in the mysql database, but I can't find where. Anyone have any bright ideas how to set the transport entries to not get overwritten every time we add a user ?

Thanks alot.
