blocking port 25 on TAMULink wireless – May 15

> On May 15, 2010, Networking and Information Security (NIS) will
> begin blocking outbound connections to port 25 (SMTP) from
> devices connected to the TAMULink wireless network.
>
> All wireless users should verify their mail clients are
> configured to use the mail submission port 587. Help Desk Central
> has step-by-step instructions for many email clients at:
> http://url.tamu.edu/email. Web mail users are not affected by
> this change.
>
> Blocking port 25 helps to reduce unwanted email (e.g., viruses,
> spam, etc.) sent from Texas A&M University networks. The central
> campus mail system provides protection, however security threats
> can be mailed to other mail servers without going through the
> central campus email servers. Blocking port 25 helps to control
> these security threats.
