Timo,

Yes, it does set HOME and removing the -d option worked. Thank you! I 
was wondering if you could help me with the other part of my deliver 
setup. I'm trying to deliver mail to arbitrary files as specified by 
pathnames in .forward files. I'm using -m to specify the mailbox. It 
seems that deliver only accepts mailbox names relative to $HOME/mail, 
but a .forward file can contain any full path.

With "/home/sam/mail/dovecot-forward-test" in the .forward file, deliver 
rejects the mail by sending this in a bounce message:

     Your message was automatically rejected by Sieve, a mail
     filtering language.

     The following reason was given:
     Invalid mailbox name

     Reporting-UA: vps.uofr.net; Dovecot LDA 1.0.beta3
     Final-Recipient: rfc822; sam
     Original-Message-ID: <E1HBKjs-0004dz-PF at vps.uofr.net>
     Disposition: automatic-action/MDN-sent-automatically; deleted

Is there any way to convince deliver to arbitrary paths? I tried 
enabling mail_full_filesystem_access, but that didn't help.
