I have established rules; some work, some don't.  Most are being applied to more than one email sender, although your
Tech Support people say there can only be one email address associated with a given rule.  That's nuts because why bother to have Rules.  It's also not true since some of mine are operating with multiple senders associated with the same rule.

I understand that Rules are supposed to get applied automatically PRIOR to receiving the message in the Inbox.  I understand that I may apply a given Rule to received messages after the fact.  My experience is that it is completely serendipitous.

CAN YOU HELP ME, puleeeeeeeeeeeeze??????
