outgoing mail
In the "from" field in an outgoing Mail message, I don't see all of my accounts, and am unable to choose a Gmail account. Do I have a setting that's incorrect?
The from field is selected based on a list of reply addresses for the particular mail server you've selected. You're probably missing a few entries for whatever mail server you're currently using.
Mail.app > Mail > Preferences > Accounts > select the account > Account Information > Email Address (should be a comma-separated list of addresses)
