ATT email account indicates email sent but he messages are not received
Starting 4/14/2023 when I send email from my ATT email (using desktop), my sent folder shows the message as sent and there are no failure messages in my inbox saying could not send.
I have waited 15 minutes and the messages are not received. I even tried to send a message from me to me, never received.
I sent messages from a gmail account to my ATT account and it is received, so receiving work as expected.
I have looked for filters under "settings" but don't see anything obvious.
Not sure where to go from here.
