And you just made my point about generalizing DUL accounts of any kind,
highspeed or not. All ISP's should block port 25 traffic unless you are
paying for a business class service, in which, you should not be on a
dynamic type of IP, but have some statics, that can be properly mapped
through DNS. Even if you are just hosting your churces (or any other
non/not-for-profit organization) you are breaking the user agreement for
every home based/non business class users agreement I have read.
and, no I do not take this or your other email personally, I just believe
that there is an easy solution to fixing the majority of SPAM and email
born virus activity, block port 25 access outbound to home users, and force
them to use the proper ISP smarthost, that is why they have it for you.
IMO that is :)
Cheers!
