Question

Email message rejected for possible spam/virus content

When I do a Reply All on an email that includes my own Mail email address in the recipient list, the reply is delivered to everyone but me. I get a Postmaster@mac.com email with a Diagnostic code: "smtp;553 5.3.0 17.158.232.236 Your message was rejected for possible spam/virus content.Please ask your email provider to visithttp://emailadmin.registeredsite.com for resolution."

This never happened before. The only thing that has changed on my system is that I have recently installed Webroot SecureAnywhere antivirus. Any ideas?

MacBook Pro, OS X Mountain Lion (10.8.5)

Uninstall the anti-virus using the developer's uninstall instructions.

Similar issues happening on several of my clients as well as myself when sending mail from mac.com or me.com accounts to other email accounts NOT on apple servers.

Same error message:

Reason: Server rejected MAIL FROM address.

Diagnostic code: smtp;553 5.3.0 17.158.232.236 Your message was rejected for possible spam/virus content.Please ask your email provider to visit http://emailadmin.registeredsite.com for resolution.

One email may go thru, yet the next new email will not and be bounced back to sender. No antivirus apps exist on receiver or sender systems. Many of the emails are empty test emails with no attachments and no body.

This issue has been going on since early April 2015, often refusing emails for days, then allowing them to come thru, only to bounce them again days later.

Thank you Ian. I too have noticed that the problem will randomly occur whether AV is installed or not. I have reported this to Apple.
