503 Valid RCPT command must precede data
I cannot send emails.
All outgoing emails that i send return with an undeliverable error. I can receive emails ,but i cannot reply to them nor forward them.
New emails that i send are not being delivered also.
As soon as i send an email, i get an error. The error is as follows:
Undeliverable – 503 Valid RCPT command must precede data. When i send emails using another account they are being delivered but when i send emails from one specific account that is configured in Outlook i get this error. Others on the same network using the same domain do not have this problem. I am the only one.
Error message is below. Please do not mind. I blocked the email address and domain for privacy reasons.
