Today we have officially released the new SpamFilter ISP v3.5.3.704. It 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 major changes with this build involve the further enhanced ability to stop the new wave of spam emails containing PDF attachments.

Following is the full list of additions/fixes since the previous official release 3.5.3.692:

// New to VersionNumber = '3.5.4.704';
{TODO -cNew : Added the capability to stop blank HTML emails, in addition to blank plain text emails, with specified attachments}
{TODO -cNew : The "Exceeded Max spaces in Subject" filter now has its own separate RejectID in the tblMsgs table (ID=25) }
{TODO -cNew : Added new parameter in SpamFilter.ini to specify the threshold that defines what a blank email is : MaxLettersToConsiderEmailBlank}

// New to VersionNumber = '3.5.4.702';
{TODO -cNew : Due to memory leak issues and Access Violations in the PDF library used, by default SpamFilter will not scan for images within PDF files by setting the value SpamPDFMaxPagesToScan=0 in the SpamFilter.ini file. If this setting was enabled in a previous version however, it will remain enabled after upgrading to this version}
{TODO -cFix : Due to memory leak issues and Access Violations in the PDF library used, we have been forced to remove the ability to scan keywords within PDF files. We may re-add this functionality at a later time when a more stable PDF library is available}
{TODO -cNew : Added new option ForceDisconnectOnNonAuthorizedTO in SpamFilter.ini file to change the default behavior that forces a disconnect when a recipient is specified that is not in the AuthorizedTO list}
{TODO -cNew : Added new option DoNotDeleteExpiredEmailsFromQuarantine in SpamFilter.ini to prevent SpamFilter to perform the routine cleanup of the quarantine database by deleting old archived emails. Useful if admins want to perform their own cleanup}

// New to VersionNumber = '3.5.4.701';
{TODO -cNew : Replaced the option "BlockBlankEmailsWithPDFAttachments" added to build 3.5.4.700 with the more generic "BlockBlankEmailsWithAttachments". This allows admins to block blank emails containing any one of a list of unwanted attachments}

// New to VersionNumber = '3.5.4.700';
{TODO -cNew : PDF image filter now scans, in addition to previous content types, also "application/octet-stream"}
{TODO -cNew : SpamFilter will now block emails that contain an empty, blank body and also a PDF attachment, the new setting in the .ini file is on by default: BlockBlankEmailsWithPDFAttachments=true}
{TODO -cFix : If an email session was whitelisted due to a whitelist keyword match, if further emails were sent during the same SMTP session, they could be blacklisted due to a falase keyword match}
{TODO -cFix : 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 : In SFE, when importing the file-based settings to a domain, or when copying the settings from one domain to another, the SPF settings pass/fail were being inverted}
{TODO -cNew : If SpamFilter was installed over an evaluation version, sometimes the "Received" header in the retail version could still contain the words "Unlicensed Evaluation Copy" leftover from the eval version in the SpamFilter.ini file}
{TODO -cNew : If SpamPDFMaxPagesToScan is zero, PDF attachments are now skipped without even attempting to open them. This allows to completely disable the PDF filtering functionality}
{TODO -cFix : In SFE, sometimes new entries were not being added to the autowhitelist table}

// New to VersionNumber = '3.5.4.697';
{TODO -cNew : PDF image filter now scans, in addition to content type "application/pdf", also "application/x-pdf"}
{TODO -cNew : The keywords filter now also scans for text contained within PDF attachments}
{TODO -cNew : In SFE, a new table "tbl_logindomains" is added and a new field is added to the tbl_logins to prepare for the new ASP-based web interface for SFE}
{TODO -cFix : Exception occurred during DumpLog: Cannot open file "nnnnnnn.log". The process cannot access the file because it is being used by another process}
{TODO -cFix : Spam emails with multiple recipients, where one of them caused a match in the AutoWhiteListedForceDelivery, were not split correctly and were delivered to every recipient instead of just the whitelisted one}
{TODO -cFix : Warning: error (1) scanning PDF for spam - Access violation at address 005BEEED in module 'SpamFilterSvc.exe'}
{TODO -cFix : Exception occurred during TTerminateIdleThreads.Execute: Invalid floating point operation}
{TODO -cFix : Exception occurred during TTerminateIdleThreads.Execute: Access violation at address 0040A753 in module 'SpamFilterSvc.exe'}
