I am having a difficult time adding a second account to the Lion mail app. I believe the problem is that I have two accounts that are the exact same in terms of spelling (one is my school email, the other is a gmail). So they both have the same name and incoming mail server(imap.gmail.com). I already forward the mail to my gmail account, but occasionally I need to send mail from my school email. Mail seems to think Im trying to add the same account twice. Is there a solution to this? I am really enjoying the new mail layout.
