This is sadly true and possibly the result of spamming
traditionally coming from compromised home PCs. Some
providers offer you to use their MX, so if you're using
sendmail as MTA, let it hand its messages to your ISP's
MX as a realy which will then identify by a "good IP".

This can be configured in your sendmail's mc as follows:

	define(`SMART_HOST', `mx.your.isp.blah')

Note that most relays will only accept messages coming
from the respective ISP's net, so when you try to use
it from a different ISP, it will deny your access.
