RCN does selective blocking of port 25.  They allow port 25 traffic 
inbound to your computers, but all outgoing port 25 traffic must be 
routed RCN's mail gateway.  Its not a bad price to pay, but it was 
inconvenient when they started it.

I'm pretty sure you can get around all of this is you upgrade to a 
"business" account.  You may have to pay for it though.

Not entirely true, they offered a 6MB service to my daughter in 
Attleborough for $60 a month plus installation (her apartment building 
has a choice between Comcast or the owner's satellite package).  Much 
more expensive than the Verizon DSL plan at half that price.
