A client can send us an e-mail just fine, but when they add an attachment

There was a SMTP communication problem with the recipient's

<exchange2003.THEIR_MAIL_SERVER.com #5.5.0 smtp;553 sorry, that
domain isn't in my list of allowed rcpthosts (#5.5.3 - chkuser)>

So, is this an issue on their server or ours?

I would suggest that is a problem on theirs unless you have any kind
of software in front of Exchange that checks for attachments or does
any kind of pre-processing.
