Hello -- I have email with the subject line like
fax from <phone-number>
where phone-number contains 11 digits -- How can fine the email that contain part of the phone number, ie just the area code?
It seems if I specify 1xxx where xxx is an area code, I get nothing back since the subject line contains a complete phone number
Is there a way to search the subject line with regular expressions?
