Cannot Send E-Mails to Multiple Addresses
 

Can anyone help? All of a sudden, I cannot send e-mails using Yahoo Web Mail to my contact list of 60 people. My e-mails to Yahoo customer service have been answered as follows: "the system is working as designed". Their documentation states that I can send to up to 100 addresses at a time. When I point that out in my e-mails to them, I get the same canned reply that the system is working fine. Then why can't I send e-mails? It is very frustrating and they obviously don't care. If anyone can help me, I truly appreciate it!
