Why not get the server to send out the messages with an appropriate
envelope sender (return path) in the first place?

Replies go to addresses in the headers, not the envelope. So you can
have them different.

That won't work at all. With respect, you seem to be very confused about
the way bounce messages and system filters work.

1. In a system filter $local_part is never set (because a message may
have many recipients).

2. When $local_part is set (e.g. in routers) it is never empty - after
all, the message has to be addressed to some recipient!

3. A bounce message has an empty SENDER address.

Yes after posting i realised I should be using $sender_address_local_part.

the reason I cannot use a different address to send mail out from the server
is that its an application thing that I have no control over. A different
department.

They send mails out to the internet as info@domain

Any bounce messages generated from this mail needs to be captured and mailed
to a certain person.
The messages which are delivered successfully may reply in which case I have
aliases for info@domain to forward to some real address somewhere.

I know replies go to header address and not envelopes but software such as
outlook sends its from address you set in the options as the envelope
address I think anyway ( please correct if wrong ).

So Is there an easier way to capture actually bounce messages as opposed to
just catching mail sent to or from certain addresses.

I have tried below now, but still no joy.

if $sender_address_local_part contains "<>"
then
deliver xxxx@domain2.com
endif

What you want to do is set the following on the outgoing SMTP router :

errors_to = ${if eq {$sender_address_local_part}{info} {the_bounce_receiver@your_domain.example} {$sender_address}}

this will change the envelope so that bounces go to the desired address.

You can change the envelope (see above). It doesn't matter that
outlook (or whatever) sets the envelope undesirably. It also doesn't
matter that they are in a different department.
