Re: Comcast decides to block port 25 IN and OUT with no notice.

I received this email about it, is it what you're talking about?

Dear Valued XFINITY® Internet Customer,

We care about your email security when using our network. On August 1, Comcast announced that for security reasons we will no longer support the use of port 25 for sending email from programs like Outlook or Apple Mail. It appears that one or more computers connected to your Internet account are using port 25 to send email. A port is a connection through which information flows from a program on your computer, from another computer in a network, or to your computer from the Internet, Port 25 is an unsecured port, and it is increasingly used to send spam emails through malicious computer programs called malware. These spam emails are usually sent by computers that have been infected by viruses, and as a result, most users are unaware that their computers are sending spam. By no longer supporting port 25 to send e-mail, this will help prevent your computer from sending spam without your knowledge.

What You Need To Do:

We are asking you and other impacted customers to change your email program settings to port 465, which provides more security. You will be unable to send email over port 25 once it is disabled, and you will need to update your settings to port 465 in order to continue to send email. Please click the link below for your current email software and follow the step-by-step instructions to change your settings.
