    Posted: 13 June 2014 at 2:57pm
We have officially released the new SpamFilter ISP and SpamFilter Enterprise v4.6.0.113. 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.

There are two major changes in the 4.6 version of SpamFilter compared to the previous v4.5: 

1. SpamFilter v4.6 includes support for the 64bit versions of Windows. Separate binaries are included for x86 and the x64 platforms.

2. The optional Norman antivirus plugin has been replaced with an AV engine from CYRUS (also known for their F-PROT antivirus solution). This plugin is available for both the 32bit and 64bit versions of SpamFilter.

The full list of changes since the latest official release (4.5.1.98) is as follows:

// New to VersionNumber = '4.6.0.113';

{TODO -cFix : If a domain has multiple destination SMTP servers (for failover), and the first destination server is online but rejects the email with a 400 or 500 error, SpamFilter would not be able to forward the email to the failover server and would log an event "EMail from: user1@.... to: user2@.... --  was returned to sender - server error - Already connected.". This issue does not happen if the primary destination SMTP server is completely offline and not accepting SMTP connections}


// New to VersionNumber = '4.6.0.112';

{TODO -cNew : Added support for x64 bit operating systems}

{TODO -cNew : Replaced the Norman antivirus plugin with one developed in partnership with F-Prot and CYREN}

{TODO -cNew : Added new parameter to customize location of queue directory in SpamFilter.ini - QueuePath}

{TODO -cNew : To more easily identify compromised accounts used in AUTH LOGIN, SpamFilter will add an info warning when the AUTH LOGIN account does not match the MAIL FROM account, ex:  User authenticated with AUTH LOGIN - info - MAILFROM <> AUTHLOGIN - johnZ@logsat.com }

{TODO -cNew : Added parameters AUTHLOGINEmailsInIntervalMax and AUTHLOGINEmailsInIntervalMinutes in .ini file to limit number of emails during a time interval that can be sent by AUTH LOGIN authenticated users during the same SMTP session}

{TODO -cFix : When adding a prefix in the Subject line for tagged emails, SpamFilter was corrupting subjects that had UTF encodings for foreign charsets}

{TODO -cFix : improperly formatted passwd file for Unix authentication would cause: Exception occurred during AuthUserInPasswd: List index out of bounds (0)}

{TODO -cFix : If TLS is disabled via EnableTLSSupport option in .ini file, but a buggy remote SMTP server like MIcrosoft's hotmail and live.com mailservers will attempt to use the STARTTLS command anyways (violating RFC...), there could be an access violation in the OpenSSL SSLEAY32.DLL which will prevent the email to be delivered.}


// New to VersionNumber = '4.5.1.99';

{TODO -cNew : Added parameter MaxSPFAllowedLoops in SpamFilter.ini file. This parameter used to be hardcoded to "10" in SpamFilter and it is not customizable. It is used to limit the number of nested include directives allowed in an SPF query. Used to limit the risk of DoS attacks using malicious SPF DNS records}
