Sarah, I think I found the answer for you. (And myself, as it turns out. I
had the same problem!)
1. Open a New E-mail message.
2. Now click "View"
3. Select the "From Field" (From now on an extra header blank line will
appear for every e-mail you send. The "From" line.)
4. **IMPORTANT - Read all the way through this step.** This will work
because it reminds you (us) to select which account to use to send the
e-mail. For it to work, though, we must match the "From" line with the
"Accounts" button on the toolbar above. Now, when you send an e-mail, just
do these two things:
a. Click the "From" button and choose which account to send from.
b. Click the "Accounts" button on the toolbar above and select the SAME
account. Now there is one more grayed line on the header of your e-mail that
says "This message will be sent via...(your chosen from account)"
If you do not match the two accounts the recipient will get an e-mail that
says "From: (Your default account) on behalf of (Your "From" account.)"
I hope this doesn't sound too complicated. I have found it quite simple; and
reassuring to know that my customers and friends etc will see the appropriate
sender.
