Ok… this is driving me kinda mad… 🙂 I’ve been working at getting a POP3 mailbox to authenticate for a while now, making every possible configuration change possible except for a few things.
Scenario:
-We recently migrated to Exchange 2007 from 2003, in fact the final part of the migration (removing the old 2004 Exchange server) won’t be complete until I can get this POP problem fixed.
-Sending and receiving of all Domain mail seems to be working fine, even configuring Outlook to access POP3 email works, but not the SMTP aspect of sending of email.
-We have ticket logging software (on our Web Server) that has a POP3 mailbox configured that is still pointing to the old Exchange 2003 server.
-A certificate was never obtained from a 3rd party vendor. The default install certificate was used.
So we have two problems which could be related… the first is configuring SMTP to allow to send email through the POP3 account and the other problem is that when I try to change the mail server from the old Exchange server to the new Exchange server through the ticket logging system using secured and
unsecured ports I get the following errors:
Secured (port 995): Could not log into the mail server: Session aborted
Unsecured (port 110): Could not log into the mail server: A error occured in the protocol
I’m thinking that I’m having a certificate problem… anyone have any suggestions that might either support the need for a proper certificate, or is there any further configuration that I can make on the Exchange server that might allow for this to work?
In addition, when I configure the Outlook client to use SSL over port 25 or 587, I get the following pop message:
‘The server that you are connected to is using a security certificate that could not be verified. A certificate chain processed, but terminated in a root certificate which is
not trusted by the trust provider.
Do you wish to continue using this server?’
When I opt to continue, I get an SMTP error: ‘550.5.7.1 unable to relay’,
Port: 25, Secure(SSL): Yes, Server Error:550, Error number: 0x800CCC79′
Is this because the port 25 by default with only work with other Exchange servers? I guess this would mean that using port 587 is the only option… I still get the same error with port 587, so I’m still thinking I’m having certificate problems.
Any help would be greatly appreciated!
Thanks,
James
