AAPT Anti-Spamming Page

Unsolicited Bulk Email or Usenet News Abuse, sometimes called "spam", is a major problem for ISPs and users alike. If ISPs do not take action against their customers who spam then they may be indirectly supporting:

address forgery and breach of acceptable use policies
large-scale aggravation and expense to other Internet target-sites
denial-of-service attacks on target-sites, intermediate sites and sites used as counterfeit source addresses

ISPs who do not prevent spamming from their systems will probably have to deal with:

large quantities of email complaining about the spam or retribution by disaffected users, such as "ping floods".
possible law-suits from affected Internet sites and users
the probability that the ISP's site will end up being "black-holed", which will prevent delivery of email for *all* of the ISP's customers (see http://maps.vix.com/).

In the case of newsgroup spamming, sites that leave their News-servers open to posting from the world may also incur very large traffic costs.

It is in the interests of every ISP to block spam in whatever ways are possible -- not only technically, but by educating their users and by taking action against those who repeat their spamming offences.

ISP customers and users of AAPT services are reminded that they are bound by an Acceptable Use Policy (see http://info.connect.com.au/docs/legalese/acceptuse.html) which includes specific guidelines on spam. AAPT actively ensures that this Policy is adhered to and will take appropriate action on any breaches.

The site http://spam.abuse.net/ has an excellent collection of information on what to do to prevent spam. All AAPT customers are encouraged to make use of this site.
