Filemaker version 12??
You are using Mail as the default email client on your Mac or another (Outlook or Entourage)?
You have one email account setup - your gmail account?
You can have the organization's Gmail account setup on your computer and disable it until sending.
Changing the "From:" address in a new message in Mail can be a very handy tool for people looking to keep e-mail accounts for separate uses.
How to Change the Reply-To Header of an Email in Mac OS X Mail
Have you considered an online email service? (I use Madmimi, Mailchimp, and iContact)
Yes - I'm using FileMaker Pro 12; and yes, Mail is the default Email client on my Mac. I have the one (personal) Email account when I check "preferences" in "Mail".
The organization is "International Organization of Lace, Inc.". All board members have "permanent" generic Email (on Gmail) addresses; the name associated with the addresses changes as the board members change. When I want to send out Emails from within FileMaker, the first choice I have is to use the "E-mail client" or "SMTP Server". I tried to use "SMTP Server", but that failed. (I obviously don't know how to manipulate the information.) The "E-mail client" works easily - and that uses my personal address. So. it sounds like I need to set up a second account within "Mail"; and then enable only that address when I'm using Filemaker?
Thanks for the information.
