POP is not a mail routing protocol. It is a single client to single mailbox protocol. Perhaps you might want to read the relevant Internet RFC to better understand how it works and why it won't do what you want.
The reason this works for MAPI is because the protocol supports the redirection. That is, the client connects to the old server, and it notifies the client, through supported protocol elements, that the location has changed. Then the client updates itself and contacts the correct server. Exchange is not designed, and has never been designed, to act as a proxy for other servers until the notion of a front-end server came along. This is what it is specifically supposed to do. If you want that function, then buy the box. If you can live without it, then it's your choice. Or quit using such a limitied protocol. POP is about as basic (stupid) as a protocol can be. Of course, if you had read the RFC, you'd have known that. Whining about what Exchange "ought to do" won't get your problem resolved. Arguing with those telling you how it is won't change the architecture of the product. I think it's time for you to move on and troll a different list now.

Everything works flawlessly with<br>the exception of<br>users getting access to POP3 mail once they are on the<br>new Exchange 2003<br>server. The outside world sees our internal pop3 as<br>mail.domain.com and<br>that is setup on 300 different locations that rely on<br>pop3 access.<br><br>I do have POP3 enabled on both servers. SP1 is in place.<br><br> This is under<br>one e-mail orginization and one domain, one forest.<br>Every other<br>function of e-mail between groups in this orginization works<br>great. All<br>POP3 and SMTP is being routed to the original 2000 exchange<br>server and<br>then distributed<br>from there. When I try to access e-mail<br>via pop3 with a user on the<br>new<br>server I get an error message that the<br>user is unknown...I find this<br>interesting because as one e-mail<br>orginization, it should see every user<br>as long as POP3 is<br>enabled.<br><br>The goal is to move all users to the new Exchange server and<br>then remove<br>the old exchange server from the environment. Until then, I<br>need POP3<br>to come into a single point and see both servers or correctly<br>route<br>throughout the e-mail orginization.<br><br>Thank<br>you,<br><br>Terry<b r><br><br><br>_________________________________________ __<br>______________________<br>List<br>posting FAQ: http://www.swinc.com/resource/exch_faq.htm<br>Web<br>Interface: http://intm-dl.sparklist.com/read/?forum=exchange<br>To<br>subscribe: http://e-newsletters.internet.com/discussionlists.html/<br>To<br>unsub scribe send a blank email<br>to<br>[EMAIL PROTECTED]<br>E xchange List admin:<br> [EMAIL PROTECTED]<br>To unsubscribe via postal mail, please contact<br>us at:<br>Jupitermedia Corp.<br>Attn: Discussion List Management<br>475 Park<br>Avenue South<br>New York, NY 10016<br><br>Please include the email address<br>which you have been contacted<br>with.<br><br><br><br><br>________ ___________________________________________<br>______________<br>List< br>posting FAQ: http://www.swinc.com/resource/exch_faq.htm<br>Web<br>Interface: http://intm-dl.sparklist.com/read/?forum=exchange<br>To<br>subscribe: http://e-newsletters.internet.com/discussionlists.html/<br>To<br>unsub scribe send a blank email to<br>[EMAIL PROTECTED]<br>Exchange List admin:<br>[EMAIL PROTECTED]<br>To unsubscribe via postal mail, please contact us<br>at:<br>Jupitermedia Corp.<br>Attn: Discussion List Management<br>475 Park<br>Avenue South<br>New York, NY 10016<br><br>Please include the email address<br>which you have been contacted with.<br><br></font></BLOCKQUOTE><br><br><br><br>___ ______________________________________________________________<br>List posting FAQ: http://www.swinc.com/resource/exch_faq.htm<br>Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange<br>To subscribe: http://e-newsletters.internet.com/discussionlists.html/<br>To unsubscribe send a blank email to<br>[EMAIL PROTECTED]<br>Exchange List admin: [EMAIL PROTECTED]<br>To unsubscribe via postal mail, please contact us at:<br>Jupitermedia Corp.<br>Attn: Discussion List Management<br>475 Park Avenue South<br>New York, NY 10016<br><br>Please include the email address which you have been contacted with.<br><br><br><br>_______________________________________________________ __________<br>List posting FAQ: http://www.swinc.com/resource/exch_faq.htm<br>Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange<br>To subscribe: http://e-newsletters.internet.com/discussionlists.html/<br>To unsubscribe send a blank email to [EMAIL PROTECTED]<br>Exchange List admin: [EMAIL PROTECTED]<br>To unsubscribe via postal mail, please contact us at:<br>Jupitermedia Corp.<br>Attn: Discussion List Management<br>475 Park Avenue South<br>New York, NY 10016<br><br>Please include the email address which you have been contacted with.<br><br></font></BLOCKQUOTE> _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
