Deliver msg to multiple hosts

I'm trying to migrate a rather large mail system. As the migration will take some time, I'd like to set up a relaying postfix server to deliver messages to the old system and to the new one at the same time (2 copies of the same msg to 2 different hosts), so I wouldn't loose messages in between.

I've googled around and couldn't find a solution for that. Does anyone know if this is doable.

I've found a note to try to do a local delivery and have procmail do multiple deliveries, but apart from being more inefficient, I'm not sure if that's the way..

I'd really appreciate any pointers if someone knows anything about that.

Thanks
Jure

I am also having problems doing this. My company has it set up to serve 3 separate domains and one domain is migrating away from lotus notes. We need to keep mail flowing to the current notes server which is done by using transports of something like

mylotusdomain.com relay:[10.x.x.x]

The other domains are also using transports, some use domain lookup the other uses fragile which appears to use smtp w/o any additional parameters.

Relay uses: smtp -o fallback_relay=

as a command...

I've caught the commands that gets sent to this and it doesn't appear to do much...

/usr/libexec/postfix/smtp -n relay -t unix -u -o fallback_relay=

I am starting to think I need to make changes to smtp and recompile it to accomplish what I want.... can anyone offer other suggestions?
