BCC quit working today 5/17/19

Apple Mail BCC quit working suddenly today on Mail V. 11.5. It causes a server error on ATT/Yahoo mail.

I reset server, reinstalled mail account, and still get the message

"Cannot send message using the server selected ----) I can send list mail in CC and To lists but not to BCC lists.


I use BCC for list mailings to keep recipients mail addresses private.

Any ideas?? ATT support was totally useless.

I would change due to several reasons the least fo which is their new so called privacy policy.. but since ATT is my ISP and they use OATH (formerly Yahoo) for all mail service I am kinda stuck. In the last month the amount of spam has increased dramatically which confirms your statement. In my area I have very limited ISP options.. ATT or COMCAST..This am (5/18) all is back to normal so it had to be a ATT or OATH server issue.
