One particular domain is getting a rejection message when sending email to my exchange server.
There was a SMTP communication problem with the recipient's email server. Please contact your system administrator.
<#5.5.0 smtp;554 rejecting banned content>
The incoming email is a law firm that has a lengthy email disclosure in their signature. They are sporadically able to send email. We are only having problems with this domain. I'm assuming if the domain gets rid of their email signature and send the email in plain text it should pass through. Are there settings I can adjust on the Exchange server to allow this type of email through? I do have a Barracuda SPAM appliance in place, but I don't think this rejection is what is banning the email.
