Yes, however, the HOME environment variable is not set to this value,
nor is it in the output of getpwuid().  Given that all email is
delivered as user = "vmail" and group = "vmail", all email accounts have
the same home directory: it's the home directory associated with user
"vmail", which is /var/vmail on my system.

Yes, I can do that.

OK.  And then, I can put each user's ~/.tmda directory in
/var/vmail/virtdomain.com/user/.tmda

I'm just now setting up postfix, and therefore, I haven't set up any
special LDA.  Later on, I'll see if the standard LDA indeed runs the
.forward file from that directory.  If so, I can put something like this
into this file (one long line):

  | /path/to/tmda-filter --environ=VHOME=/var/vmail/virtdomain.com/user \
                         --vhome-script=/path/to/some-script

where where "user" and "virtdomain.com" are different for each email
account, and where "some-script" simply does an "echo $VHOME".

... or some such thing.

Does that seem right?

However, if it turns out that the postfix LDA uses the HOME environment
variable or getpwuid() to locate the .forward file, then I'm out of
luck.  If that turns out to be the case, what other options do I have?

Thank you very much for all your help.
