It means you were trying to send from a connection other than Cox.
Were you on a laptop away from home?
As a general rule, the provider of the SMTP server must match the
provider of the Internet connection.
The available workarounds when sending away from home are:
1. Use webmail for sending (via your browser).
2. Ask your home ISP if they have a port other than '25' for SMTP. I don't think
Cox does. Cable companies are very bad about accommodating travelers.
3. Substitute the SMTP server belonging to your away-from-home connection.
4. If you frequently send from multiple locations, get a free Gmail account,
configure it for POP access, and use it for your sending chores.
Gmail uses port 465 for SMTP, which is not blocked like port 25 is.
