there are tons of howto and comments for dovecot + postfix
and very little for dovecot + sendmail ... therefore, it'd be
great if we/i can get this dovecot.m4 problem resolved

status of what works and what does NOT work while testing dovecot's LDA ...

is the virtual domain a local name?

Take note of the remark "reject unknown users early".

your mailer is named "dovecot", therefore the mailertable entry in the
Wiki:

virtualdomain.example.com vmail:vmail
should spell, IMHO:
virtualdomain.example.com dovecot:dovecot
(2nd dovecot has no meaning, but there must be present something)

Post a sensable output:

echo '3,0 dovecotuser@dovecot.domain' | sendmail -bt -d21.4

there had been a post about trying to improve virtual user support in
sendmail incl. some ongoing talk. Maybe you find it and get some info back
into this list.
