We have officially released the new SpamFilter ISP and SpamFilter Enterprise v4.7.3.217. This release is available for download in the registered user area of our website. A free Evaluation copy is also available for all other users. 

As always, this upgrade is free for all users with a current software maintenance.

The full list of changes since the latest official release ( is as follows:

// New to VersionNumber = '';
{TODO -cNew : Added an option to include the email address in the "From:" header, in addition to the real envelope email address specified in the MAIL FROM command, when checking the sender's email agains the "FROM Emails" blacklist, the "Domains" blacklist, the "Excluded FROM Emails" whitelist, and the "Excluded Domains / IPs" whitelist}

{TODO -cNew : Replaced the internal RegEx library to improve speed and stability for keyword searches. RegEx search speed has dramatically increased by 16x. Sites using tens of thousands of RegEx expressions or more can see a tenfold reduction in CPU usage}

{TODO -cNew : Simiarly to how it's done for the "Subject:" header, added support for keyword blacklist/whitelist searches targeted specifically to the "From:" and the "To" headers by prefixing the keywords with "EmailFrom:" or "EmailTo", as well as to search thru ALL the headers by prefixing the keyword with "Headers:". For ex a RegEx keyword of EmailFrom:(test[1,2].com) will search for the RegEx expression "test[1,2]" in the email's "From:" hedaer}

{TODO -cFix : Some RegEx expressions with greedy serch options could cause stack overflows in SpamFilter if searching thru email content that casues the RegEX to peform a huge number of recursions to find the text.}

{TODO -cFix : A bug was introduced in build that prevented SpamFilter from starting up unless a database connection had been established}

// New to VersionNumber = '';
{TODO -cFix : In the 64bit version of SpamFilter, under high traffic scenarios (> 750,000 emails/day) SpamFilter could had times identify the wrong country when performing the IP-to-country database lookups}

{TODO -cNew : The "FROM Emails" blacklist now supports the syntax:| Wildcards are supported for both the sender and the recipient. This will cause the sender ( to be blacklisted only if one of the recipient in the email is}
