ok, let me explain the issue and if you gals and guys come up with some
solution that isn't hackish, I won't oppose it :-)

mbox is easy, no parameters need to be exposed to config, we can easily
provide a syntaxic sugar:

action foobar mbox = action foobar mda "/usr/libexec/mail.local ..."


maildir is easy, no parameters needs to be exposed to config ... except
for a single path that can be expressed as a STRING, we can easily give
syntax sugar too.

action foobar maildir = action foobar mda "/usr/libexec/mail.maildir ..."
action foobar maildir path = action foobar mda "/usr/libexec/mail.maildir path ..."


lmtp is not easy, it requires multiple parameters and people have a lot
of different use-cases with it. I can't easily provide a syntaxic sugar
and we must expose -d, -f, rcpt-to, etc... this isn't acceptable for me
so if you manage to make all options fit in one STRING I will be ok but
if I have to add keywords specific I won't.

Something like:

> > > action "lmtp-local" lmtp "/var/dovecot/lmtp"

would be fine by me, but people are using other parameters than just the
lmtp socket, or maybe we can provide a syntaxic sugar for this case, and
people using any other option must use the longer option ?
