Unable to download emails
When I go to Get Mail on the G5, the Activity Viewer indicates that it is "Fetching New Mail" and that it is "Preparing to Retrieve Messages", but never gets further than that. Connection Doctor indicates green buttons on all the Accounts.
Account info shows 188 messages (all Sender unknown) and all with blue dot (unread).
I have tried Disk Uitility/Repair permissions. I have tried removing and re-instating the malevolent Account in Mail, dumping the Mail Preferences, clearing out unwanted old emails, even dumping the complete ~/Library/Mail folder.
I have checked System Preferences/Network/Network Port configurations/ (all in correct order), Mail/Accounts/Advanced/ (all boxes checked).
Any ideas?
