[MlMt] installing on 2nd computer

I've found that it's a bad idea to have multiple machines running 
simultaneously with rules that sort and categorize incoming messages.  
What I do is have all of the rules on one machine; ditto SpamSieve.  For 
me, what works best is SpamSieve on my always-on desktop, but sorting 
rules on my laptop.  Why the split?  Spam I never want to see, so I 
always want to get rid of it quickly.  But important mail I want to see 
immediately on my phone, so when I'm not using my laptop I'll be alerted 
to inbound mail.  (I also use server-side rules for less-important 
mailboxes that I'd never want to look at on the phone, but that's a 
separate story.)
