Blocking E-mail Spam

Network Engineering uses several tools to help keep spam from reaching your mailbox. Read on for more information about what we are doing to prevent spam, what you can do, and how to keep your address off of spammers' lists.

What is Spam?

Spam is defined as unsolicited, bulk e-mail.  Typically spam comes from strangers - people who have obtained your e-mail address without your permission.  If you signed up for the mailing (intentionally or accidentally), it may be undesirable e-mail, but it is not technically spam.  Likewise, if you have some sort of business relationship with the sender, it is not spam.  So, an e-mail sent to you from your bank, an online service you signed up for, or your department at OSU would not be considered spam. 

Note: Using OSU's e-mail system to send unauthorized bulk mailings is against the Acceptable Use Policy.  For information about how to do a bulk mailing at OSU correctly, please see the Guidelines for Release of E-mail Addresses.

Blocking Spam

Step 1 - Using Filtering On Your Account

Step 2 - Reporting Spam

If Step 1 doesn't stop the spam from coming through, you can report the spam to OSU Network Engineering:

Phish Detection

For more information about phishing, please see the Phishing helpdoc page.

OSU blocks e-mail messages that contain a reply-to address that goes to a known phisher.  If practical, we will also "poison DNS" for links included in phishing e-mails, so that clicking the link will redirect you to a safe page instead. 

If you respond in any way to a phishing e-mail that asks for your username and password, we will disable your account and ask you to reset your password.  OSU has had a significant number of accounts become hacked in the past and these hacked accounts have been used to send hundreds of thousands of spam e-mails to OSU and to the world, causing serious e-mail disruption.

NEVER respond to phishing e-mails!

Where does spam come from?

In the past, most spam came from misconfigured mail servers or proxy servers. But today most spam comes from virus-infected personal computers, hacked e-mail accounts and free e-mail providers.  See the Wikipedia article on Spam for more information about how spammers operate.

One very important thing that you can do in the fight against spam is to keep your computer up-to-date on software patches and anti-virus software. It's also a good idea to run a personal firewall. Use caution when opening e-mails from addresses you don't recognize, and always scan email attachments for viruses. If your computer has become noticeably slower, it's a good idea to run virus-detection software.

Finally: NEVER share your password!
