With Leopard now out in the wild, a few more notable Mail features have emerged.
The new account setup in Mail lets users of popular e-mail services get started just by typing in their e-mail address.
Simple Account Setup One problem that many users have when starting off with an e-mail application is getting their accounts setup. Knowing all of the SMTP, POP, and IMAP servers can be daunting, especially if you have several accounts.
Apples new account setup will allow many users to start using Mail by simply typing in their e-mail address. Mail already knows the settings for 30 of the most popular e-mail services including Yahoo, AOL, Gmail, Verizon, AT&T, and Comcast. After you type in your e-mail address, Mail takes care of everything else for you. If you dont have one of the services that Mail automatically recognizes, you will have to set up the accounts manually, just as you would with the previous version.
actually, this won't work if you've enabled imap gmail. you have to enter in the settings manually.I thought that it was updated in Leopard so all you have to do is put in your email address and the Mail app does the rest.
I hope this helps.
