CONTROLLING e-mail SPAM
 


Operation Secure Your Server

Incoming spam may be clogging your e-mail box. But did you know that the settings on your servers may make it easier for spammers to send more spam mails? This website shows individuals and organisations how their mail servers or proxy servers can be abused by spammers. The website is a combined effort of the international community.

Making Use of Realtime BlackList - Paul Vixie

The Mail Abuse Prevention System's Realtime Blackhole List can be used by anyone who wants to configure their own network or mail relay, with a view of blocking spammers from stealing their server resources.

Filtering spam using heuristic with SpamAssassin

SpamAssassin is an open source mail filter that uses a range of heuristic tests on e-mail headers and body text to identify spam. Once identified, the mail can be tagged as spam for later filtering.

Filtering spam using Distributed Checksum ClearingHouses

The DCC or Distributed Checksum Clearinghouse is a system comprising thousands of clients and more than 175 servers that collect and count checksums related to several tens of million mail messages per day. The counts can be used by SMTP servers and mail user agents to detect and reject or filter spam. DCC servers exchange or "flood" common checksums. The checksums include values that are constant across common variations in bulk messages, including "personalisations”.

Configuring your Mail Server with Sender Policy Framework (SPF)

Standard SMTP e-mail is anonymous and can be forged. Using a “Sender Policy Framework” can help to close the loophole. The framework works by giving spammers a taste of their own medicine - when the framework is activated, you will be able to tell where the spammers are coming from, and block that domain.

 

ELECTRONIC MARKETING TIPS
 


1. Requirements for Compliance with Spam Control Regime

Singapore ’s Spam Control regime provides a framework in which spammers – be it through e-mails or the mobile phone – must follow. Some of these guidelines include the use of labels <ADV> to mark a message as spam, and to offer an unsubscribe option. Non-compliance with these requirements could result in civil penalties for the spammer.
The use of dictionary attacks or address harvesting software to spam is strictly prohibited under the regime. Persons who authorise the sending of these non-compliant spam will also be subject to the same civil penalties.

2. Unsubscribe Facility

To comply with the regime, each spam must have:

a)Contact information - That can be in the form of an e-mail address, an Internet location address, a telephone number, a facsimile number or a postal address that a recipient can use to submit an unsubscribe request. It is strongly suggested that this contact takes the same form as the spam message itself – an e-mail spam should offer an unsubscribe facility through e-mail, while a mobile SMS spam should offer a reply via the recipient’s cellphone.

c)Clear statement – This will state explicitly for the recipient that he or she could use the above contact to submit an unsubscribe request. This statement should be in English. But if the statement is presented in two or more languages, the English language shall be one of the languages.

The above contact should be a valid contact for at least 30 days, that could receive unsubscribe requests from recipients of spam. The use of this contact should not cost the sender of unsubscribe request more than the usual cost of using such a contact.

Once an unsubscribe request is submitted, the spammer should remove the recipient’s electronic mail address or mobile phone number from the mailing list within 10 business days.

Anyone who receives the unsubscribe request should not disclose the information to others, except with permission from the sender of the unsubscribe request.

3. Labelling and Other Requirements

Responsible marketing includes the simple courtesy of correctly informing the recipients about the content of the message. So, each spam should include

a) Correct and not misleading title in the subject field of the message, if the message has a subject field.

b) <ADV> before the title of the message, or in the case where there is no subject field, before the actual content of the message.

c) Correct and non-misleading header information where applicable.

d) An accurate and functional e-mail address or telephone number by which the spammer could readily be contacted.

4. Civil Recourse Against Non-compliant Spammers

If you have suffered loss or damages as a result of the transmission of non-compliant spam, you could also seek legal recourse against the spammer. This takes the form of a civil action against the spammer in court. You could also seek civil action for those who authorise the sending of non-compliant spam.

If successful, the court could grant injunction, damages, and statutory damages. Statutory damages that could be awarded would be up to S$25 per non-compliant spam, up to a maximum of S$1million. If you wish to claim damages beyond S$1million, you could opt for grant of actual damages instead. In addition, the court can order the spammer to pay for the costs and expenses of the legal proceedings.
