Well, I can now report that I am able to actually see the email inbox for my Virgin Media email account for the first time in nearly a fortnight, both via the web and through an email client (Windows Live Mail in this case).
Sadly, this is not the end of my problems. While I can now send emails from my account, a few test messages that I sent to myself from other accounts to make sure everything is OK have not been delivered.
One of these was returned some time later with an error report stating "451 Temporary local problem - please try later (state 14)". I will report back if I get to the bottom of this.
For those who are in the same position as me, and currently enduring having their personal email account migrated to a new system in a somewhat cack-handed and haphazard manner, I should point out that you will need to change the settings in your email client in order to access your emails.
With the move to a system based on Google Mail, email accounts are now using SSL encryption to send and receive messages. This must be enabled in the account settings for your email client, and also uses different TCP/IP port numbers for POP3, Imap and SMTP than before.

UPDATE: Virgin Media has been experiencing further email issues in March 2011. See V3.co.uk readers up in arms over Virgin Media email outage and Virgin Media email issues drag on for two weeks.
