port filtering list

[chrisb () kippona com]

Does anyone keep track of packet filtering based on destination
port, of the form:

 provider         ports            action
------------------------------------------------
  uu.net         25               drops all outbound
  <another>.net  25,465,587       drops all outbound
  aol.com        ??               ??
  msn.net        ??               ??
  earthlink.net  ??               ??
  demon.co.uk    ??               ??
   ...           ...              ...

More and more users want to roam and knowing this info ahead of
time helps.
