Spam Policy

The company policy is that does not send spam.

Posting of spam using the e-mail address of an INRO employee is fraud. Any misuse of addresses is considered fraud, and will be addressed accordingly.

What is UCE / spam?

Unsolicited Commercial E-mail, also known as spam, is the mass electronic distribution of unsolicited e-mail to individual e-mail accounts, aliases, or mailing lists and archives. These messages are considered to be a nuisance and their contents can be offensive, illegal, or simply misdirected advertising.

Why adopt a UCE / spam policy?

The problem of spam costs money and wastes resources. With conventional junk mail the sender must pay for delivery to recipients. Enormous amounts of unsolicited e-mail and spam are paid for by the recipients in the form of wasted bandwidth and system resources!

Fighting UCE / spam

At INRO, we use multiple methods to fight spam to protect INRO's computer network and INRO employees:

  • server-side spam filtering software
  • a compiled list of known spammers/abusers
  • client-side spam filtering software
