Handling Spam

Spam is the common term for Unsolicited Bulk (marketing) E-mail (UBE) that comes from various sources to your inbox. Your e-mail address can be obtained from a variety of sources, including online orders, contests, surveys and warranty registrations.

While spam is usually regarded as an annoyance, spam can be a risk to security and system integrity. Spam is often delivered with an attachment containing a virus, worm, or malware or spambot software.

IT filters spam for @unm.edu and @salud.unm.edu email accounts, meanwhile, spammers become more sophisticated every day. To protect UNM accounts and optimize mail server performance, IT filters messages based on many criteria. Only five percent of nearly five-million daily e-mails arriving at UNM pass through filters to inboxes, so it should not be surprising that spam gets delivered.

E-mail Best Practices

When in doubt, delete. If you don't recognize the sender's address or the content looks suspicious, then delete the e-mail. Do not even open the e-mail if you are not sure of its authenticity.

Never open attachments from suspicious emails.

Create a spam filter. See FastInfo Answer 414.

Forward any non-tagged suspicious e-mails to spamdrop@unm.edu. Non-tagged e-mail contains no rating percentage in the Subject line, e.g., [SPAM?? 61%].The forwarded email will be reviewed by IT and the spam filter vendor in order to refine the filter rules.

Spam and Filtering

Fine tuning spam filter rules requires information and access to e-mail content that is normally inaccessible because of privacy concerns. No filtering schemes are perfect and false positives (legitimate e-mail identified as spam) are filtered, while false negatives (spam not identified as spam) are delivered to your inbox.

If you have an @unm.edu or @salud.unm.edu email address, the information provided in your e-mail headers can help IT fine tune spam filtering rules.
