How to spam filter keyword in the attachment,such microsoft office file,TXT file,html/htm file,PDF file.

Some spammer may just send attachment (such as randon_name.docx) to avoid key word filter of mail body. As far as know,there is function to look at the concent of the attachment,but not how to filter keyword in it. 

Tommy,

The current content filters in Xeams do not look inside the attached files. We can certainly add this in the a future version of Xeams.

Pls add it,i think it is a good function to filter spams,only filter documents,only those without password protected documents.

Some spammer may send email with random title,body,attachment name,but same content in the attachments.

This function you can consinder soon,as some spammers using thousands of outlook.com to spams,only send microsoft word attachments with only few random words in content.
