postfix-users: Source code change for verp always

Source code change for verp always

On one of my servers (postfix 2.7) I need to do verp in such a way that
I need to add recipient-id to envelope sender

so if sender is ram@senderdomain.tld -->ram-1111@senderdomain.tld
1111 is the numeric id of the recipient.

Also I need to do VERP always , irrespective of whether the client sends
an XVERP command or not.

Wietse had suggested that I do a source change to do always VERP which I
can easily do by making a change to src/smtpd/smtpd.c

I guess the src/global/verp_sender.c -- verp_sender() function is
where the encoding happens. But somehow any change I do does not seem to
Is this the right file to check.
