Mail App can't work with my IMAP provider
There is no way in the Mail App to explicitly specify a username for an email account - I guess it just assumes it's whatever is in front of the @ sign in the email address. However, my ISP uses the entire email address as the username for accessing the account, so I can't use the Mail App for this account. I was able to in 10130. Anyway, if anyone can think of a workaround, I'd be most grateful. I sure can't think of anything...
