I am using windows mobile 5.0 on a cingular 8125.
I want to accomplish the following:

Receive email notifications for only CERTAIN emails.

Another words, reveive an audible alert for an email that is important to me but not for junk email/personal email.

It's a real pain for the device audible alarm going off for every email that comes in day or night. I need to know when I get certian email messages but I couldnt care less about junk/non important emails.

If I could customize the alert (say by subject ot by sender) to only trigger an audible alert for those emails.
