Hi,
There is a mail sending issue in our email server. We can't send emails to outside domains only from one email account(user3@domain.test). But we can send from other email accounts. all incoming emails are working. This issue is only for one email user. I have attached the delivery error report. Can anyone help me to resolve this issue pls..

Re: Can't send emails to public domains
Hello,
you must verify and clean your public mail server IP.
You must check that your public server IP has a reverse DNS and your public server hostname resoved with same IP.
Also check your EHLO hostname.
And use DKIM and SPF to get better score at SPAM detection.
