To configure it with sendmail, modify
sendmail.cf like this:

To feed it a MIME mail directly at the command line:
% bbsmail < message.txt
This script relays e-mails sent to "*.bbs@domain" as mails to BBS user
mailboxes; it is designed to be a drop-in replacement for the MAPLE BBS
utility of the same name.
This program could be used serve multiple BBS sites, each distinguished by its
domain name. MIME encodings, multipart messages, quoted words are all handled
correctly.
If supplied with a web directory, attachments could be saved for later download.
You could restrict the max. allowed size of each attachments.
If the optional "HTML::Parse" and "HTML::FromText" modules
were installed, HTML-only mails and simple HTML attachments could be rendered
as plain text.
Currently this script does not check proper permissions; you could use the
"OurNet" backend to achieve restricted permission. See bbscomd for
how to run an OurNet node.
However, authentication is currently not implemented; while sending password via
e-mail is easy, the author finds it distasteful. A proper way to parse
PGP-signed mail might be the only viable route, and any contributions on that
front will be most welcomed.
OurNet::BBS, bbsboard.
