Jeff,
If the dial-up accounts are going to use Outlook, you can set Outlook up to
authenticate to the SMTP service.
That way you don't have to add all of those cardiac depleting IP addresses.

Just enable the "My server requires authentication" option in Outlook in the
Account Properties|Server tab.

Subject: [IMail Forum] smtp relay and ip addresses


Presently, i have my system setup for relay for a few specific
ip's relating to my internal machines.

I am beginning to offer dialup service through a wholesale
arrangement.  I want to be able to let my dialup users access
email from a standard email client like outlook express.

I have a list of the ip addresses used in the modem pool for
dialup accounts.  From my understanding, i need to add these to
the list of acceptable machines.

Is there anything further that can be done to help prevent smtp
abuse from non-customers.

I am concerned because as a rebiller of UUNET services, a zillion
people will be using those same IP's.  This does not give me much
comfort.

Looking for any advices at all. Specific questions:

(1) Is anyone doing this?

(2) Is imail going to have a heart attack if i enter a hundred ip
ranges.

(3) Are there other steps I can take to help prevent abuse by non-
customers using the same generic UUNET ip pool?

Any and all comments appreciated.

Jeff
