NAME

       bincimapd - IMAP4rev1 server

SYNOPSIS

       bincimap-up [options] -- <authenticator> bincimapd <maildepot>

       bincimap-up -- /var/qmail/bin/qmail-authuser bincimapd Maildir

DESCRIPTION

       bincimapd implements the IMAP interface to the user's <maildepot> by
       name which could be Maildir++ or IMAPdir structured.  Upon invocation
       bincimapd switches to the home directory available by the user
       environment and performs the commanded IMAP operations on the given
       <maildepot>.

CONFIGURATION

       bincimapd shares the same environment variables with bincimap-up, thus
       there is no specific configuration required and therefore [...] is
       usually avoided, except for its first unqualified argument containing
       the name of the mailbox depository in which bincimapd should search for
       folders. If unset, some authenticators like qmail-authuser and vmailmgr
       will fail. However, bincimapd runs in the environment of the user and
       honors the a specific setting of environment variables to cope local
       preferences.
