Can't send to some email addresses

There are several email addresses that can't receive emails from me.

I have my own domain email address, I'm not using gmail or yahoo, my email address uses my websites domain.

At first I figured they mistakenly blocked me, but one of the addresses that can't receive from me is my mum and she has had me go through every setting within her email client to attempt to fix the issue.

I get the error at the bottom of this message.

Any thoughts?

I EDITED the email addresses with XXXXX

    Hi and welcome !

    AUP#1160 is an Acceptable Use Policy error indicating that the email being sent goes against the security policies. This is usually associated with items such as attachments or emails that fall under the definition of spam.

    Yes, thank you. I got that from the Spectrum site, but since I am not sending spam and I am not send her an attachment, the error code doesn't apply.

    My domain has a legitimate website with an SSL certificate.

    I am emailing my mother who has a address. The thing is, if she's not receiving emails from my legitimate email address, there is a good chance she's not receiving emails from clients.

    I even moved my site and email to a new host and Spectrum is still giving me that error. My email server is secure and encrypted like all email servers should be. Only Spectrum is a problem. I can send emails to everyone else without an issue. So what is the problem with Spectrum?

    Thanks. Attachments and spam are just possible examples. There can be other reasons. It sounds like the issue may be with her email. Are you able to successfully send her email to the domain from a different email address?

    Wanted to hop in here. When you login directly to her email (not 3rd party client) do you see anything forwarded or blocked?

    She doesn't have anything forwarded or blocked.

    Yesterday I figured out a way to get around Spectrum and she was able to receive an email from me. This really shouldn't be this hard.
