However that might not play out quite as well as just letting them
shoot themselves in the foot - if you put a "stealth" MS box in front
of Exchange, then management would just think that the Microsoft stuff
did just as well as the old Linux software. It might be better to
explain it should be tested with and without the Mailscanner solution
as a comparison. However if Nigel is leaving, why not just let them
fight their own war!<br>
<br>
Nigel, I presumed you pointed out that in addition to the £16k for
exchange they would need something to stem the spam-flow, and given
their need for "a throat to squeeze" (the usual reason) it would
probably be commercial?<br>
<br>
Using SPF, Greylisting and MS I think I'd guess we're blocking
99.5-ish% of all spam and the of the remaining .5%, a good
three-quarters is getting 6 SA points or more. I'm almost getting
confident enough to drop the "high-scoring SPAM" level down and also
the marking threshold. Does anyone have any figures (rough or
otherwise) or experiences about such adjustments (I was thinking to
take high-score to 8 and marking as possible spam down to 5 or even 4).<br>
<br>
BTW, after deploying SPF checks I was shocked to find at least one
major UK and international finance house has a badly configured SPF
record (ie not all outbound sources in the record, and a "-all" rule
ending.) As a hint their "old" (sensible) name suggests they hail from
somewhere east of Peterborough.<br>

so keep MS infront of the scary M$-Exchange stuff so keep all the bad
stuff off the email servers. be interesting to see how much spam/cost a
commercial version does. (hey if the want commercials there's always
FSL;-)<br>

I may be going off list too. Not that I want to, but our company was
bought out and the new owners find Linux 'scary stuff' and so they have
decided to take our 3 main Linux mail platforms and move them to their
comfort zone (MS Exchange) - I estimate that's £16K in client licences
for Exchange alone! Don't ask - I have briefed them, drawn up a cost
benefit analysis and encouraged them to do a SWOT analysis on our
whole, extensive, Linux infrastructure but they cannot get the Board
out of the 'Microsoft or bust' mentality.<br>
<br>
It's a great shame as MailScanner is a great app and the List is full
of great, helpful people. The only saving grace is that I am moving to
a hi-tech electronics/comms company as IT Manager and they are already
heavily into Linux for in-house apps and as the core of one of their
products and one of my first tasks is evaluate their creaking IT
infrastructure so their Exchange server is up for a fitness review!<br>
<br>
Two weeks to go as I watch the empire around me crumble!<br>
<br>
Keep up the good work and I'll see you all somewhere else.<br>
