The exact question from the company that is supplying the information is below:
>Please talk with the spamcop guy and find out how to unblock .mlk files from >authorize[at]treasurecoastsoftware.com.
I am no expert, but the email is a special protection that allows restriction and tracking data of emails sent.
What we are seeing is SpamCop blocking emails with .mlk files, but not reporting this in the held mail, or in sending the sender a report on why they are being blocked. We by hard work have traced it back to spamcop.
I would like to have a service email address for SpamCop to ask for specific technical help, and or for them to contact me directly as I need these email fuctions ASAP.
Thanks for your assistance.
