[naimmisrap]

Hi Guys,
I'm super newbie here and wanted to learn more about cPanel. I have 1 Bounce email error received by our staff but i couldn't figure out what is the issue that triggering it. I didn't understand the error code. Can some help me to see what's the issue?

Code: This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error.

Hey there! It looks like the destination you were trying to send that message to has filtering setup to block the attachment type you were using. If you try sending the email without the attachment you may get better results, and that would also be a good way to let them know about the issue. From what I'm seeing, there isn't anything you're doing wrong on your end.

I see~ Now I understand a little bit about the error. Thanks to your explanation. So that's what it is.
I got a gist of it but since I don't know much about cPanel, I need some guidance >.<. Thank you for the heads up! You're awesome~

In this particular situation, I don't think there is anything you can do on your side besides sending the message without the attachment. You could possibly link to the file in a Google Drive or in a folder on your webserver, but it is something the recipient would need to resolve on their end.
