I upgraded to Mountain Lion recently. My email changed as well. I used to have my 40K emails in different mailboxes and now I realize that the new way to do so is with 'smart mailboxes' (I actually like it).
At home, with an iMac: the transition to ML was OK until today when I had a problem with my outgoing emails. I decided to take the approach of 'delete the account and rewrite the settings':
- that caused all my emails (except 200 that are 'live' on my server) to disappear from the iMac.
Elsewhere: at my office, everything is on a Mac Pro, which also runs Mountain Lion.
Is there any way to retrieve all my emails? (Do I still have the old email's folder somewhere?)
If not, then with the data on the Mac Pro at the office: how can I export/import back home?
