Cant see address from field

What mail page? Some webmail page? Or something in Mail.app? If you're talking Mail.app, are you talking about the Account pulldown menu when you are composing a new, or replying or forwarding an existing, message? Or are you talking about the message viewer window, that lists all your messages received, draft, sent, junk, trash, etc.?

If the former, if you only have the one email account set up in Mail > Preferences > Accounts, single click on that account name to highlight/select it, and doublecheck your (Mail > Preferences > Accounts >) Account Information's Email Address field, to see if you still have more than one email address listed there. Multiple addresses should be separated by a comma and blank space.

If the latter, go in the menubar Mail > View > Columns > and make sure that From is checked.

Okay, so you are talking about when composing a message in Mail.app, that you don't get the pull-down "Account" menu to choose from which account to (or email address alias to apparently) send from.

Have you yet tried looking at Mail > Preferences > Accounts, single click on your email account name to highlight/select it, and doublecheck your (Mail > Preferences > Accounts >) Account Information's Email Address field, to see if you still have more than one email address (each address separated from one another by a comma followed by a blank space) listed in that field?

Graham,

Is this a .mac, or another type of account?

So all email address names and aliases show up in Mail > Preferences > Accounts > Account Information > Email Address field. They show up as
user1@domain1, user2@domain2, user3@domain3, ...
with comma+space delimiter between addresses/aliases?

If so,......hmmmmm........then I must defer to others on this forum....
