Cox also filters your e-mail on their SMTP server such that if it contains both words "root" and "password" it will get silently dropped. This is why I'm using an alternate port to bypass their SMTP server (or you wouldn't get this e-mail). Grisha On Wed, 9 Jun 2004, W. Mark Herrick, Jr. wrote:

Does anybody else know of other cable/DSL providers that simply block outbound port 25? thanks armanW.
