What is the best email ANTI-SPAM GATEWAY solution i can get for multiple domain at a reasonable price ?<br />
Is there something good in open source ?<br />
<br />
GRBLADES ANSWERED ME THIS:<br />
Spamassassin is the standard open source anti spam software. Even products like barracuda use it but with their own front end and management application (which allows them to charge for it).<br />
You then interface spamassassin with whichever mail server you want running. Personally I prefer Postfix and Mailscanner and I have documented my setup at <a href="http://www.gbnetwork.co.uk/mailscanner" rel="ugc">http://www.gbnetwork.co.uk/mailscanner</a><br />
<br />
MY QUESTION IS:<br />
Do i have to install both spamassasim and mailscanner?<br />
If yes, Which on to install first ?<br />
<br />
Thanks,

MailScanner and Spamassasin

An email client, email reader or more formally mail user agent (MUA) is a computer program used to access and manage a user's email. A web application that provides message management, composition, and reception functions is sometimes also considered an email client, but more commonly referred to as webmail.

Internet / Email Software

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.

AntiSpam

An email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. A web application that provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Email clients can also have other systems, like calendars, notes and contact managers.
