You basically write a script that processes incoming lines on stdin, and
writes back to stdout. The protocol is described in smtpd-filters(7).
This basic idea in lua would be something like:
for line in io.lines() do
if line == 'in' then
io.write('out')
end
end
Now handle the lines you want to handle, and respond to them how it's
described in smtpd-filters(7).

I'm simply unable to start.
I have to know where to get the mail from, format of text, which
process to give the return to, in what format, i.e. are there any
standard return values for accept or reject mail.
Thanking you

Post your script that you got so far, explain where you get stuck/confused, and
someone will probably be happy to help.

Can you please help me with a sample script for accepting or rejecting mail in
lua.
Say there is myfilter.lua within /etc/smtpd/
Can one please help with a sample whose pseudocode goes like
fetch(mail)if mailbody contains foo, reject,
else if mailbody contains bar, accept.
Such a sample script would help very much to support users write their own custom filters. Thanking you
