pop email issue

[Andy Shellam (Mailing Lists)]

Hi Steve,

Many thanks for your reply, I think you're getting close to figuring out 
what's been going on!  It does sound quite confusing.
Yep as your Exchange 2000 machine has a public IP as well 
(204.87.111.232) that's why you're phone can connect to it, but since 
the mailbox was moved off it, evidently it cannot route to the correct 
box (you can cluster Exchange so it will route a request from one server 
to the correct one, but this is way out of my expertise; Exchange is not 
one of my favourite products!!)

telnet 204.87.111.232 110
+OK Microsoft Exchange 2000 POP3 server version 6.0.6249.0 
(MXI.occa.state.ok.us
) ready.

What might help to know, is your Exchange 2000 machine's DNS address 
resolves to "mymail.okcca.net," which might explain what the phone used 
to connect to, as "mail.okcca.net" is a different machine and doesn't 
have any POP3 or IMAP mail services running on it, unless the DNS 
changed around the time the mailbox was moved.

I'd suggest you set up a public IP for your Exchange 2003 machine (not 
sure if you can backwards-migrate mailboxes on Exchange?)  and then 
create another DNS entry "mymail2.okcca.net" which points to the 
Exchange 2003 server's public address.  Then you can tell your phone to 
connect to "mymail2.okcca.net."  JOOI, are there other accounts on the 
Exchange 2003?  Are you planning on migrating your 2000 boxes to 2003?  
As it might make more sense to simply re-direct mymail.okcca.net to the 
2003 box, and move all 2000 boxes on to it?  Depends what your future 
expansion plans are!

Hope you get there!

Kind Regards,

Andy.
