A. Terms of service.

B. Filters of two kinds (the first of which has two sub-kinds):

1.  List operator's ISP (a) blocks port 25 except to its own servers or (b)
diverts the traffic to its own servers

2.  Recipient's ISP does not accept incoming port 25 connections from the
list operator's IP block.

If list operator has static IP AND suitable reverse lookup for his domain,
and his ISP doesn't do static IP out of the same subnets that it does
dynamic, then #2 is much less likely--and so is the TOS problem.
