ISP filtering port 25

[Bob Jonkman]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I left Rogers for two reasons: Filtering port 25, and changing my IP
erratically even though I was supposed to have a static IP (they still
had those in 2001).

I switched to Teksavvy in 2005 (maybe earlier). Teksavvy understands
that static IPs are the ones that don't change, and they don't filter
any ports.  Static IP is an extra service for which I pay an
additional $4/month, which also gets me newsgroup access and an MLPPP
connection. Even with an extra $4/month I'm still paying half of what
I did with Rogers.  Admittedly, Rogers speeds exceed anything Teksavvy
is able to offer in my area, but I'm comfortable blaming that on Bell.
