I received the following error message: "ERROR:550: E-mail message contained a virus.''

In an effort to control the spread of computer viruses, our email system rejects the transmission of infected emails.

If you attempt to send an email containing a virus, you receive the following error message:

"ERROR:550: E-mail message contained a virus."

Viruses continue to become more sophisticated. Little or no action is required to pass along an infected file. Typically, you are not aware your computer is infected. Unfortunately, spammers often take advantage of virus-infected computers to send spam. To help put an end to the spread of email viruses, any attempt to send a message infected with a virus through one of our email system's outbound residential SMTP servers results in the message being rejected by the company's server. This policy has been designed as an additional measure to protect you from spam and email viruses.

If you are unaware why your computer is sending out infected email, there might be a virus or Trojan program running on your computer. It is possible for an infected or compromised computer to send out email messages without your knowledge or consent.

Recommendations to Help Secure Your Computer

To help secure your home computer, you should scan it for existing Trojans, viruses, and security vulnerabilities, and take some of the following precautions:

  • Always use anti-virus software, and make sure that your anti-virus definitions are up to date.
  • Consider the use of a firewall.
  • Turn off all unnecessary services on your machine.
  • Make sure that you are up to date on all relevant security patches for your machine's operating system. Check Microsoft Update and Apple security updates for more information.
  • Turn off file- and print-sharing services on your machine.
    • Home networks, if in place, should be considered before taking this step.
  • Be aware of where and when you enter passwords, logins, and other sensitive information on the Web. Do not give out personal information, logins, or passwords.
