I've noticed that ISPs are starting to block outgoing port 25 connections except to their own mail servers. They are doing that for the same reason not leaving your mail server open relaying is a good idea, which is: spam prevention. In this case it is to prevent the other ISP customers, not your colleague necessarily, from connecting to any of the thousands of known open relays on the net or to make 'direct to MX' connections. They figure the main reason one would want to do that is to spam. My home ISP does this and I have not found it inconvenient. Your colleague's ISP should be providing mail relaying service and I should not think it would be difficult for him to use it?
Some ISPs do refuse to relay even for customers if they change the return address to one that is not "@" that ISP, though. My ISP does not do this, thank goodness. If you have to relay for him, I think the best advice is to use an authentication system as discussed. But not relaying is to me a better plan, much easier to support! Just my quick 2 cents.

I like your comments. I wish I knew the answers to your ISP question. However, all I know is my boss wants me to figure out a way to achieve this. I am really not in a position to question him, unless I find reason that this is a bad idea. I would like to provide him a solution as well as pit falls to the solution. Thanks Ben -----Original Message----- From: Benjamin Winzenz [mailto:[EMAIL PROTECTED]] Sent: Monday, November 19, 2001 10:53 AM To: Exchange Discussions Subject: RE: Email Forwarder If I read this right, he is asking you to allow him to send mail using your server, while he is dialed up to his ISP. Did I get that right? Confirm or correct me, and I and others can comment. If I am correct, he is asking you to allow him to relay. BAD Idea. What kind of ISP restricts individuals from sending mail out? Has he done something to earn that restriction?

I have a colleague that wishes to send out mail. His ISP however, is restricting him from sending mail out. He wants to know if he can send mail out from our email server, I guess sort of be a forwarder for him. Is this at all possible? If it is how can I actually do that? Or do I have to create an account for him and have him use pop3 settings etc.? Thank you all in advance for you much appreciated knowledge and feed back. BTW I have an exchange 5.5 sp4 server on NT 4.0 sp6a.
