Cox the High Speed Internet provider of cable modems. Beginning Wednesday, June 25 2003 has filter access to all 3rd party outgoing (SMTP) mail servers. What they did was to block port 25 that SMTP uses to send emails Since I am on a cable modem at home I can no longer use my own SMTP server I have on a T-1 at anther location and must use COX SMTP server. Big disadvantages (1) no SPAM or Anti-Virus checking (2) 5Meg email attachment size limit. To get around this on my email server on the T-1 I added the built-in SMTP server that come with IIS and Windows 2000 but changed the default port number from 25 to 26. Now I have two SMTP servers on the same server Imail ver 8.0 and Declude Junkmail and Virus using the standard ports so not to effect all my other emails and domains and the second SMTP using port 26 so I can send emails to my server from home over the COX cable modem. This allows me to still have SPAM and virus checking for my cable modem customers and over come the COX imposed 5Meg limit. COX sent out the below email message Dear Customer, With the increasing popularity of always-on High Speed Internet connections, the potential for unsolicited e-mail, or SPAM, has also increased. This is not only considered a nuisance by our valued customers, but also potentially degrades customers e-mail service by consuming network and mail server resources. SPAM also increases the potential for computer related virus attacks. In an effort to protect our customers, as well as other members of the Internet community receiving e-mail from Cox customers, Cox is currently engaged in an initiative to reduce the amount of SPAM originating from our Cox High Speed Internet network. Beginning Wednesday, June 25 we will filter access to all 3rd party outgoing (SMTP) mail servers. You may be connecting to a 3rd party mail server because of one of the following reasons: - Your e-mail software, such as Outlook Express, is configured to use a 3rd party outgoing mail server to send e-mail, with or without your knowledge. - Your computer may be allowing other users from the Internet to connect to it. These outside users may be using your machine to 'relay' their e-mail. We recommend that you review the security of your PC. - Your computer is infected with a virus that is attempting to spread itself via e-mail. We recommend that you update your anti-virus software and scan your machine for viruses. We believe that by putting this filter in place, we will stop 9 out of 10 spam e-mails coming from the Cox network. This will not only improve the experience for all Internet users, it will help insure that other Internet Service providers do not take action to block legitimate e-mail from our users. Following the implementation of this filter, any e-mail software configured to use an SMTP server other than smtp.east.cox.net to send e-mail from your computer will no longer work. Although you will still be able to read any e-mail sent to you, an error message such as the one shown below will appear when you attempt to send e-mail to others: A time-out occurred while communicating with the server. Account: 'otheraccount.otherisp.com', Server: 'othersmtp.otherisp.com', Protocol: SMTP, Port 25, Secure(SSL): No, Error Number: 0x800CCC19 Customers using 3rd party email services must re-configure their email clients to use smtp.east.cox.net to send outbound e-mail. You will find detailed instructions for configuring your mail client to use Cox servers for outbound SMTP e-mail traffic on our support site at the following URL: http://support.cox.net/custsup/email/settingup.shtml If you have a personal vanity domain you may still be able to use it in your e-mail address, as long as you use Cox e-mail servers when sending outgoing messages.

Thank you for choosing Cox as your High Speed Internet provider. Regards, Cox High Speed Internet Team Sincerely, William J.
