As a user of the EMWAC IMS mail server, I have written a couple of little
pieces of software that improve the usability of the IMS server software.
You should definitely check out Paul Sica's web page, which is kind of the
central connection point for the IMS support community. You can find it
The first utility I have written is called SpamEye, which is designed to aid
users of both IMS and SCSMFilter (see the link above) quickly sift through their
trash bin and delete mail that's not wanted, and forward mail which is. You
can find SpamEye here: SpamEye subfolder. Make sure
you browse the short readme on installation instructions.
The second utility is SMTPRCV, which is a service designed to replace the aging
SMTPRS which lacks some fundamental MTA features. SMTPRCV adds the functionality
of antirelay at the SMTP interface, implements reverse DNS lookup on the incoming
IP to replace the "unverified" section in the Received: header line with a
correct rDNS lookup (provided a reverse entry exists), and allows refusal of e-mail
from blacklist-type DNS list mail servers
(see http://www.orbs.org and
MAPS RBL realtime blacklist) at the SMTP
interface level. Note that this service is based on an open source code codebase,
and like SpamEye, is distributed as freeware with no warranties whatsoever, so use
at your own risk. Find SMTPRCV here in the SMTPRCV subfolder. The
source code for this project is also here, although sometimes it's not 100%
current. If you need the latest version or have questions regarding this source code,
feel free to contact me (competent software developers only please).
UPDATE:I am no longer supporting this project. I have released all source
code and the latest revision at this point. There are two versions which are present
in the subfolder, v0.45, which has been running in the field for over 2 years by
several dozen people that I know of (and countless many more I'm sure) and is
sufficient for almost everyone. Then there's v0.48, which I ran internally for over
a year, and includes a couple bug fixes that don't matter to 99% of the people using
it and a new feature that traps small amounts of spam. If you are downloading SMTPRCV
for the first time, I suggest you download SMTPRCV.ZIP, which is version 0.45.
If you have problems that cannot be explained (such as the delivery agent crashing
once in a while since installing SMTPRCV, go ahead and download v0.48 and try it.
Please read the config.txt file for a short description of the new feature.
Lastly, I am no longer actively supporting this project. What you see is what you
get. I have released the source to both versions, and you are free to download and
modify if you so choose. I checked the Nevrona website, and v7.037B which the server
is based on is still available (Feb 5, 2003). If you need support for SMTPRCV,
I highly recommend you seek out the IMS user list, as a large number of people there
run SMTPRCV, and have lots of experience with bringing it up and maintaining it. You
can find the list at email@example.com. You may try to e-mail me, but
since this account is for the company I used to work for, I cannot guarantee it will
stay active, and my new job has me very busy, so it may sometimes take me a couple
days to get back to you.
