What is SPAM?
Verzija na srpskom

Spam is flooding the Internet users with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services. Spam costs the sender very little to send -- most of the costs are paid for by the recipient or the carriers rather than by the sender.

What are spamers doing?

One of the methods used by spamers is to pour messages to News conferences that are not meant for advertising or by persistent repetition of messages. A message is usually sent simultaneously to great number of conferences. Those more experienced Internet users have already learned how to recognize SPAM - if a message is sent to a great number of conferences they realize that it has no real value for them. News SPAM prevents efficient conference usage by showering them with ads and irrelevant messages.

The other way is sending email messages to individual users. Spamers create lists with email addresses by scanning News conferences, stealing email lists or by searching websites containing email addresses. SPAM incurs expense for all Internet users who receive unwanted messages, in two ways:
- in case of dial up service, more time is required to download messages
- if you pay your Internet time based on the real traffic, your bill will be higher because of greater number of messages.

The latest research has shown that 80% of total number of messages today is SPAM. The reason for such an increase is that new and small-scale companies have found an inexpensive and easily accessible way of advertising and offering new services in order to attract new clients.

What do we do about it

InfoSky has strict anti-SPAM policy, so in order to withold SPAM and protection of our users we use world black lists of domains used to SPAM. Also, we are maintaining our own black list based on reports of our users.
Practically, it means that any email sent form domain which is either on world black list either on ours will not be delivered to any InfoSky user.

How to check if a domain is on black list?

If you wish to check if domain is on black list of ISPs and other organizations which are fighting SPAM visit http://openrbl.org/ and enter IP address of server that delivered you SPAM email.
If you receive message which looks similar to this:

(127.0.0.7) 66.216.66.216 is DNSbl listed. by blackholes.ordb.org

added 2002-09-05; SPAM support - dns server for http://www.extrarape.com on 64.49.220.20
added 2002-05-20; SPAM support - hosting sky08.com
added 2002-04-08; SPAM support - abuse@rackspace allows listwashing

it means that server from which mail was sent is on someone's black list.
