Sure, I understand the drawbacks.  And that's why I haven't even 
considered it until now. But here's the thing:  I have tried everything 
I can to diminish the spam intake ( SpamAssassin with all the "latest" 
rulesets, RBLS, DNS checks, Bayes filtering ) and still, enough gets 
through that it annoys my users (and me too, I still get 100+ per day 
).  The problem is that it's really not the type of spam we used to 
get, where it was easy to detect it.  Most of these are well-composed 
solicitations, just completely unwanted.

When my users see their friends using C-R systems and getting ZERO 
spam, how can I expect them to listen to my lecture about good 'net 
behavior and accept that I refuse to offer it?  They simply don't care 
about anyone else's inbox other than their own.  And, I can sympathize 
with that.  As a facilitator, I feel it is my duty to at least give 
them the OPTION of using it ( with my lecture about why they will anger 
some innocent people ) rather than to flat out refuse to implement it.  
Sysadmins care about netiquette and fixing the problem as a whole but 
*users* only care about the sysadmin "fixing their Inbox".  And, 
frankly, that's my job... so that's why I am asking...

Also, I'm still looking for help on how to implement "dot files" for 
virtual users that have no home directory..  Isn't there some way to 
offer features like Vacation responders for virtual users?  I feel 
embarrassed that when asked to set up an auto-responder that I have to 
tell them I can't do it, especially when I hear "MS Exchange can do 
that, why don't we use Exchange?"
