The easiest way would be to allow recipients to have access to a web page and
add sender addresses themselves. The developer (Emmanuel) has a system in
place which does this already I believe, but it's based on custom scripts.

I do hope at some stage this year to build a web interface to milter-greylist,
the issue isn't getting it done (relatively easy) just finding the time I can
sit down and do it.

I've been thinking along these lines for some time now, to allow the web
interface to add/remove whitelist/blacklist entries by people with accounts,
but for this to work I'd need to have milter-greylist support "include"
statements in the main greylist.conf file so I could use something like:

include greylist.whitelist.conf
include greylist.blacklist.conf
include greylist.spf.conf
include greylist.rbl.conf
include greylist.country.conf
include greylist.greylist.conf

etc in it while allowing easy manipulation of the respective files. I think I
raised an "include" file system some time back when I started to think about
the web interface side of things, but without actually sitting down and
working on it there's no reason yet to ask for it.

I use the spf facility to reject messages at the MTA. Before using it so much
SPF:Fail trash would come through, after using it, rejects at the MTA meant no
more came through with Fails, and I've never had even one complaint about
rejecting that SPF:Fail'ed mail.

Michael.
