Go to Address Book > Create Group > Drag 5 email addresses > Save Go to Apple Mail > Group does not show in the Address Panel, but if I type the Group's name in the To: field the group shows up. Fine till there, but if I try to send the message I get a warning that pop-up saying that it does not seem to be a proper email address in the To: field. If I send the message anyway I'm not allow by the chosen outgoing server (no matter which one I choose from many I have available. If I open Address Book the group is there and if I right-click on it I can select send email to group...which takes me to Apple Mail, but from there the same thing happens > my mail goes nowhere. I have other groups that I have created a long time ago and they all work fine. Maybe something got screwed during a system upgrade or the likes? I'm running 10.6.8 and Mail 4.5. MAybe I can delete Mail's .plist but I'm not sure if I'll lose any of my settings, rules, contacts, etc. Thanks in advance for your help.
