Just to put a slightly different consideration on this, to look wider than 
MS.  You may well other cluster-like services at your site where you wish 
similar "mostly common but with individual minor variant" configuration. 
If so, then you might wish to investigate things such as "cfengine" which 
allow you both to hold configurations together across machines, but also 
to do some controlled variant-tailoring.

So the MS bit of our cfengine config has some clauses that apply to all 
hosts, and some that apply to particular sub-classes of our MS machines. 
Those sub-classes might be conceptual (inbound MX gateway; outbound 
smarthost; internal SMTP submission) or particular tweaks (on our random 
variety of hardware different "Max Children" settings).

Obviously that is a bigger and wider and longer-term thing than a quick 
fix to just MS, but it might be a service-wide question worth asking (even 
if the eventual outcome ends up "not applicable".)
