Applications :: Multiple Email Sender Addresses In Apple Mail?

I have one IMAP email account and setup various email aliases. I used for each alias also a sender name. I tried to setup different sender email addresses and names in Apple Mail but did not succeed.

I was only able to add a comma separate list o email addresses to one account but not different sender names for each email address.

BTW, I also can't setup different accounts for each email address because they share the same IMAP Mail Server with the same account username and password.
