X-CM Header

Attachment Manager and Content Manager

Attachment Manager and Content Manager add headers when they quarantine an email message.

Note that if you set Attachment Manager or Content Manager to block or blackhole a message, there are no message headers.

Attachment Manager Headers

If Attachment Manager quarantines a message, the message will not have normal spam headers. Instead, there will be only one header:

X-pstn-disposition: quarantine

If the sender appears on the organization-based Approved Senders list, the message containing the attachment will be passed on to the recipient inbox. The header will look like this:

X-pstn-attach-addresses: from sender@address.com (approved)

Attachment Manager does not evaluate the user's Approved Senders list.

X-CM Header

If a Content Manager filter is triggered, the following line appears in the headers:

X-CM: (name of triggered Content Manager filter)

For example:

X-CM: ConfidentialBilling

You can set filter names when you create or edit Content Manager filters.
