I do not have a printer like this, but it is possible that a multifunction device will send scanned documents as an e-mail in this form. In this case, the links, which I simulated above using a blue underlined font, both lead to a now defunct URL: http://freebooksdfl (dot) info/main.php . The domain is marked as suspended for spam or abuse in whois. One of our handlers reports seeing similar e-mail but not being able to capture any of the content on related links so far.

Observing never ending port scans against my systems was one reason I started DShield.org back in 2000. Still today, DShield shows that these scans continue to happen today. It is the goal of a port scan to find vulnerable services. Later, the attacker will use this recognizance to exploit these services.
In order to protect yourself, two basic measures need to be taken:
1 - limit listening services.
As part of your standard configuration, you should turn off all unneeded services. A service that is not running can not be attacked. Of course, you will also need to monitor any changes to this standard configuration. The control of listening services should not stop at controlling services commonly installed on the particular host, but the control should include rogue services as well.
Here are a few ideas to review listening services on hosts:

review the output of netstat regularly. Netstat will show any listening services. Of course, in the case of rogue services, an attacker may use root kits to mask these services from tools like netstat.
review ephemeral port usage. If a port is used by a listening service, it can not be used as an ephemeral portal for outbound connections. You will see a gap if you plot all used ephemeral ports on a system.
regular port scans. Periodically scan your systems for listening ports. However, be aware that an attack may have masked the use of the port and will only respond to requests from a particular source
Network monitoring: Tools like pads are able to detect new services on a network passively. This may enable you to detect hidden services as soon as the attacker connects to them.

2 - applying firewall rules.
Back in 2000, firewalls were a lot less common then they are today. Today, systems arrive with host based firewalls. Many times, the firewall is already enabled to block all inbound traffic by default. In addition to host based firewalls, a well designed network should include network firewalls and take advantage of capabilities in devices like switches to further limit network traffic.
