Microsoft and other internet companies will announce lawsuits against spammers under the US Can-Spam Act, and will detail a technical initiative aimed at stopping the onslaught of unsolicited e-mail.
The lawsuits announced under Can-Spam (Controlling the Assault of Non-Solicited Pornography and Marketing) will be among the first since the law took effect on 1 January, and will target "serial spammers".
Microsoft will also discuss plans for its Caller ID e-mail specification, the sender authentication technology which aims to thwart the spoofing of e-mail addresses.
The technical initiative is presumably meant to supplement the antispam efforts being made under Can-Spam.
Microsoft called the news a "exciting initiative being undertaken by leading companies in the mobile, internet, and IT industries".
Leading internet players such as Yahoo and America Online will be taking part in the announcement.
The internet industry has welcomed the Can-Spam Act as a good first step at fighting spam, but many have said that it does not go far enough to solve the problem.
The law requires commercial e-mail to have an opt-out message, allowing recipients to choose not to receive further communications from the sender, bans techniques such as e-mail harvesting and sets out other guidelines on sending commercial e-mail.
