Hi All,<br />
I am working with email gateway to send our marketing emails. Often I have seen many refusals due to bad content formatting. My emails are categorized as SPAM by ISP.<br />
<br />
We have drupal content management system and an add on to send mass emails , I am rying to use SPAM check sites as below. Somehow it's not working for me, these sites return same spam score for any of email. <br />
<br />
Does anyone know a good freeware email spam checking gateway.<br />
<br />

Drupal is an open-source content-management framework written in PHP used as a back-end framework for websites and is also used for knowledge management and business collaboration. The standard release of Drupal contains basic features common to content management systems, including user account registration and maintenance, menu management, RSS feeds, taxonomy, page layout customization, and system administration. Drupal runs on any computing platform that supports both a Web server capable of running PHP and a database to store content and configuration.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.
