HOMESTEAD - HELP

E-mail Messages are NOT SENDING!!!!

This is a really hassle with customers on the business side of things.

We reply but our customers get NOTHING!!!

NOT GOOD!!

PLEASE, PLEASE, PLEASE GET THIS FIXED!!!!

Can't send to customers, can't send in the same network, sometimes things go through and sometimes they don't but you don't know because there is no error message coming back.
WE PAY FOR SERVICES! GET THIS FIXED!!!!

This has been going on for my E-mail now for nearly 2 months on and off messages with messages NOT sending.

No way to run a business.
