Dan,
Using your own SMTP from a dynamic IP (cable, DSL and modem access, for
example) fails because of (the brain-dead) black-listing of dynamic IP blocks to
prevent spam -- see
http://dynablock.easynet.nl and
http://www.pan-am.ca/pdl/
Also, as seems to be the norm now, most viruses come with a primitive
SMTP engine built into them -- which, again, taints dynamic IPs (since
many home machines are inflected).
Cheers,
Ed Gerck
