I support a small SBS 2008 network who use Demon to host their domain and Demon has just changed its servers.
We changed the MXrecord with the new name servers/IPs and everything is working fine except one mailbox is refusing to download the emails through the POP3 connector (they don't want to change to SMTP and it's only 5 mailboxes).
The mailbox details in the POP3 connector are the same as the others i.e.
POP3 Server - mail.demon.co.uk
Ports - 110
Logon type - BASIC
Username - email@example.com
Password - XXXXXXX
I've been staring at it for ages for syntax errors.
No email comes through to this mailbox, but if I use the same details in Outlook 2010, it works fine and downloads everything, so the details must be ok at the Demon end.
