Email News Bulletin

Changes to SMTP
Posted: Tuesday, December 22nd, 2009

OIT continues to battle the problem of blacklisting. Attackers are abusing a service offered through the UT VPN, access.utk.edu, to send spam through OIT servers. Starting on Tuesday, December 22nd around 4pm, OIT will limit the rate at which a user may send emails through the VPN to discourage the spammers from abusing this service. We have gathered a list of mail servers that send email and these servers will be whitelisted for rate control.

Users connecting to the centrally-managed email service using an Exchange-friendly client (such as Outlook, Entourage, or Tmail) will not be affected. This change will only impact users connecting to the VPN and sending email using an IMAP or POP client. If you have questions about this change, please contact the HelpDesk at 974-9900 or http://help.utk.edu/.

New Wireless Networks are Available, Nomad to be Retired!
Posted: Thursday, December 17th, 2009

Start using the new wireless networks now to avoid a disruption in your wireless service! On February 3rd, OIT will retire the legacy wireless network, nomad. In order to continue to access the Internet through UT’s wireless network, you will need to move to one of the new wireless networks, ut-open or ut-wpa2. Starting Tuesday, January 5th, if you are still using the nomad network, you will need to open a web browser in order to get connected. At that time, you will be directed to an information page about the wireless changes before continuing to your browser’s homepage. For more information about these networks and assistance connecting to them, please check out the HelpDesk Knowledge Base, http://oit.utk.edu/helpdesk/kb or contact the HelpDesk at (865) 974-9900.
