Ok. This won't work. My test system had all the variables set in the shell, which is why it worked. :( The reason it won't work is that qmail-local is the parent process of both vdelivermail AND deliver. If vdelivermail sets HOME, it does not apply to deliver's environment. :(

On the up side, with vdelivermail sending the mail to STDOUT, if you do

|/usr/local/vpopmail/bin/vdelivermailstdout | /usr/local/libexec/dovecot/deliver -d $...@$host

It should deliver.. I'll try and test this tonite - on my test system I received an error 'email' in my INBOX when $EXT and $HOST didn't exist on my commandline. The caveat being you need to run the dovecot Auth on each machine that does delivery. :/

The other option would be for vdelivermail to call Dovecot's deliver after setting the environment.

Programming question - if I write to fd0 (STDOUT), and then exec() a process, will that child process see the data I put in fd0 from the parent? Maybe I'll just try that as well.

I attached a patch, but I think testing this is going to be a pita
unless someone has some sort of shell 'vdelivermail' tester ?

:O Holy crap it worked.  Not only did it compile without error, but it
actually worked as expected.

The command:

cat /home/vpopmail/domains/havokmon.com/rick/Maildir/cur/1236799820.50282.mx.vfemail.net,S=3365:2,S | env -v EXT=rick HOST=havokmon.com HOME=/home/vpopmail/domains/havokmon.com/rick /usr/local/vpopmail/bin/vdelivermailstdout '' r...@havokmon.com

Causes the ./vdelivermail (which is compiled to send to STDOUT) to
display the email in the terminal

If I run:

´╗┐cat /home/vpopmail/domains/havokmon.com/rick/Maildir/cur/1236799820.50282.mx.vfemail.net,S=3365:2,S | env -v EXT=rick HOST=havokmon.com HOME=/home/vpopmail/domains/havokmon.com/rick /usr/local/vpopmail/bin/vdelivermail '' r...@havokmon.com

The email will be delivered to my mailbox. So I've got a decent test

Now appending deliver to that first command line:

cat /home/vpopmail/domains/havokmon.com/rick/Maildir/cur/1236751658.43485.mx.vfemail.net,S=3436:2,S | env EXT=rick HOST=havokmon.com HOME=/home/vpopmail/domains/havokmon.com/rick /usr/local/vpopmail/bin/vdelivermailstdout '' r...@havokmon.com | /usr/local/libexec/dovecot/deliver

And it worked too!  Wow.  I'm blown away.  I need a glass of champagne.
Not that I didn't think it would work, but that it worked 'pefectly'
without throwing an error on the first try. :)  I think it took me
longer to figure out how to test it in a shell.

The only problem I see is the new message starts with a (null).
(null)Delivered-To: r...@havokmon.com

Now the null occurs whether I use deliver, the original vdelivermail, or
the new vdelivermailstdout, so I think its part of the cat.  I'll work
on it a little more tomorrow, so I can go to bed happy tonite :)
