Thankyou,
I will send you the mailer 'kit' and the optional information
regarding the extern dependancies, and a referrer incase you need to
know more info.
The files are complete and intact (the kit was found before the people
had a chance to rm a thing).
Notes for others (security minded) while this kit is examined more ::
It was not well installed, a better trained Unix user would have made
this thing extremely well hidden (the installation was the main reason
the machine was even seen,i suspect this would be running nice and
safe on many other mail apps, and even now i have started to see a
qmail.* ebay-spoof,so perhaps they hve even patched)
This was a 'good' coder/s, but they obviously have some trouble with
facets of running/maintaining a fBsd machine using Qmail.
The webdownload info (3 sites it somehow uses),and 5 irc servers on
Undernet.org seem to be the actual source of the controlling.
As mentioned,its unfound and the closest I could get to examining it
was after many many hours and alot of help and use of rKhunter.
The only reason i have not forwarded this to an A/V company is my lack
of faith in them,and simply no time, my apoogies.
For the A/v who are keen to improve theyre apps;
The FreeBSD Port of F-Prot was running nice and happily alongside it:(.
(The app that actually spotted the malfunction after running tests
seem to be rKhunter,but that only displays some 'possibles' , as
mentioned,it will run happily with F-prot,hence i assume it has been
encrypted well). Also, strangely, It shows up as an 'infected' file
using a heuristics test with AVG (www.grisoft.com) on Windows,using
theyre "free" version.
Regards,
Drew B.
PS: Excellent job with rKhunter,I look forward to any help i can give
and get from rKhunter :-)  , regarding 'spare time' i would help
gladly.
Expect the complete kit in 20mins max Michael,again thankyou.
