Allow/Block Email Lists

This is my two cents....Our email system was set-up over 10 years ago and was working quite well with blocking and allowing emails.  Now, I have two late fees on my bills due to the fact it was blocked originally with Sophos, unbeknownst to anyone.  Now, I have to constantly scan the blocked emails, just in case I missed one that is important to me personally or business wise.  I cannot explain to you that this is a PIA.  One more time, I will not sit idly by and be charged for late fees and let it go.  By the way, even my own internet/phone bill was held in the blocked emails.  Don't fix what was not broken.  Technology is advancing quickly I understand but damn what a pain to surf through all the BS to find anything.
