Is there a way do something like that with deliver?
why not do it on MTA level? those already have the hooks for it normally. no need to reinvent the wheel imho.
Sometimes it's virtual users using dovecot userdb or something like. MTA isn't aware of it (all it uses for virtual user is mailbox presence). But each virtual user have own wordlist for bogofilter. deliver would set some environment variables like $HOME to desirable values for such virtual user and then we have good place to call filter pointing it to virtual user home directory.
Indeed, that would be more straight-forward than what's currently needed (from an administrator's point of view, at least).
We have postfix configured to pipe to-be-delivered mails into a shell script that takes ${recipient} (the recipient's e-mail address) as first argument (here is the relevant part from master.cf):
spamcheck unix - n n - - pipe flags=DRhu user=maildeliver:maildeliver argv=/usr/local/libexec/spamcheck_and_deliver ${recipient}
The script then pipes the mail through /usr/bin/spamc -u 'left part of e-mail address' (which lets spamassassin's spamd do the checking and
insertion of headers, and thanks to the -u parameter for each user a
separate bayes_journal, bayes_seen and bayes_toks file is being used).
That output then gets finally piped into deliver -d 'e-mail address',
which files the mails into the inbox/spam/unsure mailbox, according to a
global sieve script that checks the headers previously inserted by spamd.
My private bogofilter setup is simpler, since it's just for me, but you could do it similarly, by specifying the user's bogofilter wordlist directory (-d ...) in the shell script (I think).
