SPAM in outgoing email:

Our policy on the sending of unsolicited bulk email is simple:

You may not use the service to send "SPAM" mail (unsolicited advertisements sent by email or cross-posted to multiple newsgroups). 
You may not use a his.com mailbox as a contact point for SPAM mail sent on this or any other system.
You may not use SPAM to advertise a web site that uses a HIS-hosted domain.
Host computers connected to the HIS network may not be configured so as to allow relaying of mail from unaffiliated systems to the internet (i.e., you may not operate an open SPAM relay).

SPAM in incoming email:

UBE (Unsolicited Bulk Email, also known as "SPAM") has become a tremendous problem on the internet. Most people who've been on the net for any period of time (sometimes only a day or two) have received email advertisements for golf balls, investment scams, sex web sites, or causes of various kinds.

SPAM isn't just annoying - it uses a large percentage of the internet resources (backbone bandwidth, server resources, support staff time) that providers and their customers pay for. The quantity of spam has increased dramatically - on an average day, more than 99% of the incoming mail to our email servers is spam.  On a bad day, the ratio of spam to real mail has exceeded 400:1.

We employ a number of methods to combat incoming spam, and despite the amazing volume of spam we're able to block about 99% of the junk.  Since it isn't possible to eliminate all spam without risking blocking of non-spam mail, some spam will still get through.  

If you receive a questionable solicitation that you would like to forward to the Federal Trade Commission, please forward it to uce@ftc.gov.
