Gmail bouncing mails sent from my web mail

Gmail is bouncing all email sent from my webmail, but this is not the case for yahoo mail and other mail service providers.

There isn’t enough information there to give you much advice.

What’s failing on gmail? Are you getting an SMTP error or is it going to spam? Have you made sure your SPF/DKIM/DMARC records are correct?

each time i send message from webmail to a gmail it returns this error message

this is a qmail-send program at cpanel I’m afraid i wasn’t able to deliver your messages to the following address. this is a permanent error; i ve given up. sorry it didn’t work.
