We appreciate you have sent us the detailed message you have received from the server.

Apparently your emails are getting blocked by this protection server for the reason that your email address is generating unsolicited emails which are called Spam. This could be due to some virus in your system which can be rectified if you get a good system scan with an anti virus software.

To unblock the access please ring ABL on their WA number  08 8300 0464.

If you have any further queries please feel free to email us.

my question is how common is it that a mac is producing spam (or used as a bot)
