A new pre-release of SpamFilter (v3.5.4.716) is available in the registered user area. The changes since the latest official release (.704) are as follows:

// New to VersionNumber = '3.5.4.716';
{TODO -cNew : Added SPAMTagHeader option in SpamFilter.ini file to allow customization of the X-SF-SPAM:Y header that is optionally added to spam emails}
{TODO -cFix : Scenario: (1) a valid email with multiple recipients, (2) where a recipient-sender combination is in the AutoWhiteListForceDelivery whitelist. Results - (1) email would be delivered to whitelisted recipient only, and (2) SpamFilter would not prefix the SMTP error with a 5xx error code, thus causing the remote server to send several retries}

// New to VersionNumber = '3.5.4.714';
{TODO -cFix : "Exception occurred during TCleanupIPCachesThread.Execute: '39337.7094639699' is not a valid floating point value" and "Exception occurred during AddIPToIPCacheLimbo: '39342,4181879861' is not a valid floating point value"}

// New to VersionNumber = '3.5.4.713';
{TODO -cFix : If DoNotSendNDROnQuarantine=0, and a spam email with multiple recipients arrives, and a recipient is whitelisted, SpamFilter would not prefix the SMTP error with a 5xx error code, thus causing the remote server to send several retries}
{TODO -cFix : Errors: Blacklist cache - starting cleanup --  Exception occurred during TCleanupIPCachesThread.Execute: '39332.5030980671' is not a valid floating point value}

// New to VersionNumber = '3.5.4.711';
{TODO -cFix : Another issue with the ìtagî option that prevents the ìsplittingî of an email so that it is only delivered to the tagged recipient, and instead causes the email to be tagged for some of the other users}
{TODO -cNew : Added to logfile entries for the MAIL FROM and RCPT TO commands as soon as they are received via SMTP}

// New to VersionNumber = '3.5.4.710';
{TODO -cFix : When a recipient was whitelisted, in some cases SpamFilter would also whitelist additional, separate emails that could have been sent during the same SMTP session}
{TODO -cFix : If a recipient was whitelisted, additional "regular" recipients would be correctly rejected, but an incorrect logfile entry was added stating that they were being also whitelisted (which in fact they were not) }

// New to VersionNumber = '3.5.4.709';
{TODO -cFix : Reduced the number of memory leaks in PDF scans if documents use Cross-reference-Streams}
{TODO -cFix : When forwarding emails to the destination SMTP server, if such server rejected the emails due to a mailbox full error, SpamFilter would instead send an NDR with the incorrect bounce message "The following recipients are unknown"}
{TODO -cFix : Introduced bug in build 700 - If any filter is configured to "tag spam and deliver", SpamFilter was not processing spam with the following filters: keywords, Bayesian, images/PDF, SURBL. All other filters were applied correctly}
{TODO -cFix : Exception occurred during TestForReject: Access violation at address 0063F52E}

// New to VersionNumber = '3.5.4.707';
{TODO -cNew : Added option in SpamFilter.ini file: HideXSFWhiteListedReasonHeader}
{TODO -cNew : In SFE, SpamFilter is able to now startup even if the database server is unavailable}
{TODO -cFix : If a spam email is split so that it is delivered for whitelisted recipients but blocked for the rest, it was still being stored in the quarantine database for all receipients, including the whitelisted ones}
{TODO -cFix : The HTML parser used to detect blank html emails was expecting legitimate opening and closing html tags to define text, and was ignoring any text outside these tags. This could cause very short html emails to appear blank if they were not following correct html syntax. We are now auto-fixing the invalid html code to be less restrictive}

// New to VersionNumber = '3.5.4.705';
{TODO -cNew : "Exception occurred during FindMatchInStringList: Invalid pointer operation" errors could cause problems with the reloading of some black / white lists}
{TODO -cNew : Added the logging of the filesize when reloading the black / white list files}
{TODO -cNew : The SURBL blacklist is not being automatically sorted to allow user-defined order}
{TODO -cNew : Added options in [authentication settings] of SpamFilter.ini: ActiveDirectoryAuthAppendDefaultDomain, ActiveDirectoryAuthPrefixDefaultDomain to automatically append or prefix the default domain when authenticating users via SMTP AUTH}
