Beginning December, 2004, computers using the CSB network will no longer be permitted to send outgoing email, unless they use Yale or CSB email servers. (Why? Exceptions What does this mean?)
SPAM!
From time to time, CSB members allow their computers to become infected with viruses, or connect their already-infected laptops to the CSB network. These viruses replicate themselve and/or act as spam-sending robots by sending as many as 10 emails every second to rendom or semi-random internet addresses.
This ties up network bandwidth, allows the virus to spread, and provokes the listing of our network as a known source of spam. As a result, legitimate email coming from our network will be rejected by many recipients.
The smail-sending viruses do not use the CSB or Yale email relays -- rather, they attempt to send email directly to the target addresses. By blocking all outgoing email that goes not go through CSB or Yale or other approved relays, we stop these viruses from functioning.
If you are using Yale's webmail (or any other webmail) to send email, you don't have to worry about setting your outgoing SMTP server.
If you are using an email client (like eudora or netscpae or mozilla or thunderbird or even the insecure and dangerous outlook express), you must configure an outgoing SMTP server. This is a computer to which your email client program will send email, which will relay the email to its final destination.
In most cases, you will use mail.yale.edu, as poorly described in the Yale Email web pages.
Members of the CSB who use the same portable computer at home, on the road, and in the CSB, may find it most convenient to configure the email client always to use their non-Yale ISP for outgoing email.
The CSB maintains a list of outside SMTP servers which we allow as destinations for outgoing mail. If your non-Yale ISP or email provider is not on the list, you will be unable to send mail from the CSB network.
You may request that your ISP be added to list of acceptable SMTP servers. Requests will be granted at the CSB staff's discretion.
CSB staff may find useful implementation information at http://www.csb.core/sysadm/security/spamout.html.
