Subject: Question about root/virtual/canonical

Hello all.
After some testing I have just completely installed Postfix in all
our mail machines. It works very well. Now I have a question: in some
of our machines, I have a .forward for root that redirects mail to
rootothermachine. That othermachine collects mail for root's of several
machines and saves them in per-machine folders for some automated processing.
If I put 'root rootlocalhost' in virtual, as advised in the documentation,
Postfix adds the header 'Delivered-To: rootlocalhost.$mydomain'
When the mail is forwarded to othermachine, it tries to deliver
locally but then sees that header, thinks it is a mail forwarding loop
and bounces it.

One solution is to put in virtual: root rootothermachine
but I have the same virtual maps in several machines and I'd prefer not
to make local changes.

Other solution is to put in canonical: root rootthismachine
This works well, and has the advantage that all mails go with
addresses 'rootmachine', and I think this is convenient in the case
of root.

So, is there any drawback with this approach? If not, why the documentation
advises to use virtual instead for root?

Regards.
