Out of the blue I am unable to email an invoice to my customers. I have att.net mail and the SMTP setting has always been outbound.att.net
My email account and password are correctly entered.
I have also tried adding the port and putting in outbound.att.net:465
I thought perhaps ATT changed something, so I also tried using a gmail account, and same problem. I am saving the invoice as a .pdf and then manually attaching it to email, but that is a workaround that is more time-consuming. Anyone know a solution?
