We have officially released the new SpamFilter ISP v3.0.2.578, it is available for download in the registered user area of our website.

There have been a number of fixes and performance improvements since the last official build. This new version also features the possibility of using SSL over SMTP. This is a prelude of a new feature that will be available within the next few weeks, which will allow SpamFilter to authenticate (and whitelist) users via several methods (RADIUS, Active Directory / LDAP, Unix passwd files and usernames/passwords stored in databases).

Following is a list of additions since the last official release 3.0.1.558:

// New to VersionNumber = '3.0.2.578';
{TODO -cFix : Once more, tried to improve reliability for disconnecting servers after idle timeout expires}
{TODO -cFix : Improve reliability for TSyncSendResult2 exceptions sometimes logged in the activity log}

// New to VersionNumber = '3.0.2.577';
{TODO -cFix : SPF "redirect" modifier was not being recognized properly, causing the SPF filter to pass emails that could otherwise be blocked}
{TODO -cNew : Added support to use SSL with SMTP}

// New to VersionNumber = '3.0.1.575';
{TODO -cFix : Builds 572 and 573 could cause SpamFilter to freeze after a few minutes.}

// New to VersionNumber = '3.0.1.573';
{TODO -cFix : Again improved reliability for disconnecting servers after idle timeout expires}

// New to VersionNumber = '3.0.1.572';
{TODO -cFix : Memory leak of about 400 bytes for every email that was forwarded}

// New to VersionNumber = '3.0.1.571';
{TODO -cFix : Redesigned how emails are added to quarantine DB - now this is handled by a separate thread, eliminating issues where MySQL database locks caused connections to queue up}
{TODO -cNew : logging for quarantined events has changed as follows:}
{ the entry "EMail from a@a.com to b@b.com was received and quarantined" has a different threadID than the thread that processes the connection }
{ added log entry "Created thread (nnnnn) to add email to quarantine" to track which quarantine thread was created in the connection thread}
{TODO -cFix : To attempt avoiding "Read Timeout" server errors when forwarding emails, we attempt to transfer emails in memory to the delivery thread, in addition to using queue spool files as a backup method}
{ -NOTE- this will prevent antiviruses that scan the FileSystem to detect and stop emails}
{TODO -cNew : Added SpoolQueueFilesToMemory SpamFilter.ini option to force emails to be spooled to disk}
{TODO -cNew : Added SpamFilter.ini option to scan multiple images for spam}
{TODO -cNew : The whitelist keyword filter now scans thru all the email's headers}

// New to VersionNumber = '3.0.1.567';
{TODO -cNew : Improved reliability for disconnecting servers after idle timeout expires}
{TODO -cFix : If database is busy deleting expired quarantined email, we are temporarily suspending the archiving of new spam emails to avoid table locks and bad SQL performance}

// New to VersionNumber = '3.0.1.565';
{TODO -cFix : Whitelisted IPs where still limited by the MAXRCPT TO when sending emails with large number of recipients}
{TODO -cNew : Optimized some filter tests by eliminating redundant checks when emails with multiple recipients are received}
{TODO -cNew : Increased the logging limit from 256 to 65535 chars per line when logging "Sending email from" and "EMail from nnn to nnn was forwarded to" events}
{TODO -cNew : Changed the SQL queries that delete expired quarantined emails to better reduce the number of orphaned records}

// New to VersionNumber = '3.0.1.561';
{TODO -cFix : Quarantined emails with multiple recipients where deleted from database if one of them was force-delivered by a user}
{TODO -cNew : Support for %EMAILFROM% and %EMAILTO% tags has been added to practically all customized responses}

// New to VersionNumber = '3.0.1.560';
{TODO -cFix : Antivirus plugin is now also updating ncl.dll to handle newer compression formats}
{TODO -cNew : Added Do Not Quarantine option for the SFDB filter}

// New to VersionNumber = '3.0.1.559';
{TODO -cFix : Customer specific error when starting service from terminal services connection: "Exception occurred during FormShow: Cannot create shell notification icon" prevented A/V plugin from initializing}

I noticed that the version number under About in the Spamfilter is 3.0.2.578, yet in the release notes its listed as 3.0.1.578...

{TODO -cNew : logging for quarantined events has changed as follows:}
{ the entry "EMail from a@a.com to b@b.com was received and quarantined" has a different threadID than the thread that processes the connection }
{ added log entry "Created thread (nnnnn) to add email to quarantine" to track which quarantine thread was created in the connection thread}

Does this mean log analysis programs like Sawmill will need updating?
