Internet Newsletter for Lawyers
Various Anti-Spam organisations exist to try to curb unsolicited mail. When specific servers are reported to these organisations, they ultimately become "blacklisted" and ISPs can then use the lists to block mail from offenders to their customers. If Spam is properly reported and the lists are responsibly used, this is very effective and can stop the problem at its root. ISPs who become listed due to the activity of their customers must take responsibility to find and suspend the offending user accounts very quickly.
"Spammers" can, however, avoid becoming "blacklisted" themselves by using other people ' servers & Internet connections to relay mail on their behalf. By sending a few short commands over the Internet, improperly configured servers belonging to unsuspecting Internet users can be made to distribute junk mail. Such misconfigured servers are disturbingly common, in fact until quite recently the default setting for MS was to act as an "Open Mail Relay". This effectively allows anyone with sufficient knowledge to send their Spam at little or no cost, or risk of being identified. Many IT companies despite impressive looking certification by software manufacturers, are guilty of failing to secure servers by not changing default software settings, and/or not keeping them up to date on security service packs & patches.
ISPs with customers running "Open Mail Relays" face the very real prospect of being blacklisted, whilst the real offenders remain unhindered, other than having to find new servers to do their dirty work. In reality organisations responsible for spamming, compile lists of servers they can use in much the same way that they harvest email addresses. If this ability to hide their identity were curtailed, sources of spam would be relatively easy to detect and thus filter. To this end responsible parties, Lawyers Online included, have systems to scan for "Open Mail relays" among those attempting to send mail across their networks. The owners of such servers can be told get them properly configured or even reported directly to "blacklists".
