Problems sending replies through "MobileMe" alias accounts

Several users have experienced an issue with MobileMe email accounts where all mail is sent through the primary email address. This means that for accounts which are set up with email alias names, Mail.app will not send email with a "reply to" address as the alias, but instead use the main account name as the reply email address. As described by one Apple Discussion member:

As one Apple Discussions poster, 24Golfer, writes: "If you use Alias email names and receive emails as you normally would - and reply to an email from your Alias - it still sends it out from the proper account instead."

Mail.app fix: Add alias accounts to Mail's "Email Address" account settings field

1. Open Mail.app and go to the preferences
2. Select "Accounts" and click the "MobileMe" account.
3. Under "Account Information" add all the desired alias email accounts (including "@me.com") to the "Email Address" field, separated by commas.
4. Save the preferences and upon sending mail, select the desired alias account name in the "From" drop-down menu above the message content.
