Removing an account from Mail removes all local copies of messages for that account.
- Is there any way to retrieve all my emails? (Do I still have the old email's folder somewhere?)
If the account was for an e-mail service that uses IMAP or Exchange Web Services
In Mail, simply recreate the account. With IMAP, all messages:
- are (primarily) stored on the server
- may be (secondarily) cached by e-mail clients such as Mail in OS X
– and so recreation of the account should regain access to everything that is on the server.
If the account was for an e-mail service that uses POP
It's normal for Post Office Protocol (POP) to not leave a copy of a message on the server after that message has been delivered. (Metaphorically: your postman or postwoman does not keep copies of your mail.) However, e-mail client software may be configured to stray from that default, to leave some things on a POP server.
If you used POP for your account configuration:
If the deleted messages were on the iMac alone, and if you had no backup on a separate disk
The likelihood of recovering data from JHFS+ may be low.
OS X tends to quickly reuse space after that space is marked as free, especially if that space is an an area of hard disk that is preferred for performance.
Mobile Time Machine local snapshots provide handy backups, but this feature of Time Machine is laptop-oriented (probably not enabled on your iMac).
I don't think anyone is messing with you.
- Have you checked spam folders?
- Check your email's trash can.
There is always the chance that the email failed to send from apple's side or failed to reach you in transit. But if you tried again and everything is working fine like before, then I don't think someone is messing with you.

This happened to me too. I spoke with Apple support on the phone and because my email was an iCloud email, they said there is most likely no way I would receive the emails I missed while my storage was full. The people sending the emails most likely received a bounce message indicating the mail was not delivered.
