Spam Filter ISP

// New to VersionNumber = '4.5.0.1-beta';

{TODO -cNew beta version for the new SpamFilter 5.0. Features a completely redesigned internal SMTP engine that uses fibers instead of threads to improve performance. Features support for more features, as TLS and IPv6 (not complete yet). Support for a separate GUI to better manage SpamFilter's service under Windows 2008 and RDP will be available in SpamFilter 5.0}

// New to VersionNumber = '4.2.4.851';

{TODO -cFix : When setting the MaxMsgSizeForKeywordScan (indicated in KB) parameter in the SpamFilter.ini file, the Bayesian filter was reading it as bytes rather than KB, thus often causing the Bayesian filter to skip checking the incoming email if larger that a smaller size than intended}

// New to VersionNumber = '4.2.4.850';

{TODO -cFix : When sending NDR emails, the FQDN used in the HELO command when forwarding emails is not set to the same one used in the FQDN Welcome banner}

// New to VersionNumber = '4.2.4.849';

{TODO -cFix If the GreyListAllowed.txt is manually modified and wildcarded subnets are added, if a wildcard entry is added and one or more IPs within that subnet already existed in the file, the wildcard entry may be ignored}

// New to VersionNumber = '4.2.4.848';

{TODO -cFix If a sender in the same SMTP session (1) authenticates against SpamFilter using SMTP AUTH, then (2) sends emails to some users not being unfiltered, and then (3) sends another email which triggered one of the filters to a whitelisted user who was configured with a "tag and deliver" option - when all of the above scenarios occurred, SpamFilter "forgot" the user was authenticated and tagged the email as spam}

{TODO -cFix Updated the Setup.exe installer and default SpamFilter.ini file in Win32 directory by removing the now defunct dnsrbl.net MAPS server }

// New to VersionNumber = '4.2.4.846';

{TODO -cFix If not using the new default VerifyRCPTTOForCleanEmails=1, SpamFilter could in some cases return a 250 OK successful reply to the remote sender server even if the destination SMTP server returned a 5xx or a 4xx message when forwarding an email to it}

// New to VersionNumber = '4.2.4.845';

{TODO -cFix An out-of-memory error prevented the processing of emails over about 300MB in size}

{TODO -cNew With SpamFilter Enterprise, even if the database is offline/unavailable, we are now able to save all the settings that are stored in the SpamFilter.ini file }

// New to VersionNumber = '4.2.4.844';

{TODO -cFix Changed the internal process to insert quarantined emails into database to better handle low-memory situations"}

{TODO -cNew On startup, if running as a service, SpamFilter modifies the service properties to enable the automatic built-inWindows service recovery options so that they restart the SpamFilter service upon crash after 60 seconds"}

{TODO -cNew Modified built-in crash detector so that, in case of exceptions, SpamFilter does not continue on errors, but rather causes SpamFilter to "crash" and automatically restart. If SpamFilter is running as a service, the above service recovery options will cause the SpamFilter service to automatically restart. This should help in having SpamFilter self-recover from serious exceptions "}

// New to VersionNumber = '4.2.4.843';

{TODO -cFix Moved the connection stats from the SpamFilter.ini file to a separate SpamFilterStats.ini file in an attempt to solve an issue that can cause the SpamFilter.ini file to become 0 bytes in size"}

{TODO -cFix Solved issues that caused these errors to be logged: "Exception occurred during RECEIVEMESSAGE GetCompletedRCPTTO - continuing processing"}

{TODO -cFix The filterBase64html filter fails to stop base64 text and html attachments if the Content-Type header with the base64 indicator also contains a charset indicator on the same line}

{TODO -cNew Added support for a new parameter in the SpamFilter.ini file - VerifyRCPTTOForCleanEmails=1}

// New to VersionNumber = '4.2.4.840';

{TODO -cNew Added support for a new parameter in the SpamFilter.ini file to control if the NDR will contain the entire original email or only its headers: IncludeOriginalMessageOnNDR=1}

// New to VersionNumber = '4.2.4.839';

{TODO -cFix SpamFilter sent a line with STARTTLS in the EHLO response, even though TLS is not supported, causing some remote SMTP server to attempt a TLS connection which could eventually result in a disconnect without the messgage being received}

// New to VersionNumber = '4.2.4.838';

{TODO -cFix SpamFilter Enterprise would not recognize the "SQL Native Client" (SQLNCLI.1) provider for Microsoft SQL Server}

// New to VersionNumber = '4.2.4.837';

{TODO -cFix If a DNS server reports the error "Query Server Error" during the MX filter test, this would cause the MX test to fail even if the MX record was valid}

// New to VersionNumber = '4.2.4.836';

{TODO -cNew Added support for improperly formatted SPF records that contain multiple v=spf1 mechanisms (such records were trated as malformed and the SPF check was skipped before)}

{TODO -cFix SpamFilter Enterprise, when using a MySQL database, would needlessly reload all blacklists/whitelists settings for a domain when only a single blacklist/whitelist was changed. MSSQL was (correctly) only reloading the settings for the list that was modified}

{TODO -cNew Enabled SSL v3 when downloading antivirus definition updates}

{TODO -cNew Added entry XServerBanner in SpamFilter.ini file to customize the X-Server header}

{TODO -cNew Added entry HideXSFBlockedKeywordsReasonHeader in SpamFilter.ini file to prevent display of triggered blacklist keywords in headers}

// New to VersionNumber = '4.2.4.832';

{TODO -cFix Fixed errors introduced in 4.2.4.831: Exception occurred during RECEIVEMESSAGE: ( 1 2 2b 3 3a 4 5 6 7 8 9 11 12 13 15 16 17 18 18b 20b 20c 29 30 31 32 33 53 55 56 62 63 64 65 66 671 68 69 70 71 72 73 74 75 76a 76b 111) Access violation at address 0065542C in module 'SpamFilterSvc.exe'.

{TODO -cNew Added new parameter in SpamFilter.ini file for SpamFilter Enterprise: ChecktblReloadTableMaxRunTimeMinutes}

// New to VersionNumber = '4.2.4.830';

{TODO -cNew To avoid backscatter, if an incoming email passes all filtering rules, but cannot be forwarded (ex. mailbox full, non-existent user), SpamFilter maintains open the incoming remote connection until it can verify with the destination server that the email can be delivered. If not, a 5xx error is output forcing the remote server to generate the NDR, rather than having SpamFilter send an NDR notification email}

{TODO -cFix If the DoNotSendNDROnQuarantine=1 is set, an NDR could still incorrectly be generated if (1) the email had multipe recipients and (2) at least one of the recipients is whitelisted}

{TODO -cFix The "Settings" dialog in SpamFilter Enterprise would occasionally loose the database connectivity and would display empty domains when the SpamFilter.ini file is updated in the background}

// New to VersionNumber = '4.1.3.827';

{TODO -cFix Solved issue that could cause Access Violations in cases of emails containing a specific malformed header}

{TODO -cFix Added new option "TerminateIdleThreadsFrequency" in SpamFilter.ini file to control the frequency used to terminate lingering idle threads. Used to increase this parameter in installations where this causes SpamFilter to stop processing incoming emails}

{TODO -cFix The new feature to handle default values for specific whitelists/blacklists in domains that are configured to be customized without inheriting default values would not propagate changes to the "ALL DOMAINS" lists unless SpamFilter was restarted}

{TODO -cNew Allowed redirects to be followed for future new handling of the antivirus updates}

// New to VersionNumber = '4.1.3.824';

{TODO -cFix If a spam email was whitelisted by the AutoWhiteListForceDelivery filter, and SpamFilter was configured with any of the TAG and deliver options, the email would still be tagged even if whitelisted}

// New to VersionNumber = '4.1.3.823';

{TODO -cFix Reducing the number of times the background TerminateIdleThreads process executes from once a minute to once an hour}

// New to VersionNumber = '4.1.3.822';

// New to VersionNumber = '4.1.2.820';

{TODO -cFix Fixed issue where (invalid) NULL characters in the email's body or headers where transformed by SpamFilter (violating RFC) into "." (0x2E) characters causing emails/headers to be truncated }

// New to VersionNumber = '4.1.2.819';

{TODO -cNew Increased the priority for the "not in Authorized TO" filter moving it up in the list of applied filters}

{TODO -cNew Added the destination SMTP port when logging information about forwarded emails}

// New to VersionNumber = '4.1.2.816';

// New to VersionNumber = '4.1.2.815';

{TODO -cFix : better handling of exceptions of the kind "Exception occurred during RECEIVEMESSAGE" to try to deliver the messages anyways even if they are malformed}

{TODO -cFix : SpamFilter Enterprise could crash when duplicate domains are added via the Settings GUI}

{TODO -cNew : Added ability to specify wildcards in GreyListAllowed.txt file to exlcude large number of subnets from greylisting}

// New to VersionNumber = '4.1.2.813';

{TODO -cNew : Added entries in activity logfile to log startup mode (service/application) and to log the remote IP before country lookups are performed}

// New to VersionNumber = '4.1.2.811';

{TODO -cFix : Regression error present in build 4.1.2.810 only - sometimes the trailing tags in the various whitelists/blacklists could cause incorrect tags to be applied to other filter's blacklist/whitelists}

// New to VersionNumber = '4.1.2.810';

{TODO -cNew : Added support to specify multiple RegEx expressions separated by commas, just as regular keywords can be separated by commas - has the effect of specifying "AND" rules for RegEx. Note that a "Standard non-RegEx keyword must be specified first for SpamFilter to recognize this syntax. For example: X-SF,([a-z]), ([0-9])    }

{TODO -cNew : Added support ::NEGATE suffix in blacklist keywords - causes a MATCH if the keyword is NOT present, or causes a MISMATCH if the keyword IS present}

{TODO -cFix : Removed ability to scan for text and images in PDFs files due to instability of PDF library}

{TODO -cFix : Replaced memory manager used by compiler as the old one could cause (very rarely) crashes in SpamFilter without any errors being logged in the activity logs}

// New to VersionNumber = '4.1.2.808';

{TODO -cFix : Loops in the "redirect" mechanism of an SPF record could cause SpamFilter to crash}

// New to VersionNumber = '4.1.2.807';

{TODO -cFix : A documentation bug in the new PDF library caused a "Trial Expired" popup to appear when scanning PDF files due to incorrect licensing activation procedure}

{TODO -cFix : Fixed Access Violation errors when handling certain types of PDF files. Updated PDF library used by compiler which now uses external DLLs for PDF functionality}

// New to VersionNumber = '4.1.2.804';

{TODO -cFix : The IPCacheBlacklist was incorrectly blocking IPs that were a substring of an existing entry - ex if the cache contained 192.168.123.234, the IP 192.168.123.2 was being incorrectly blocked as well}

// New to VersionNumber = '4.1.2.803';

{TODO -cFix : The antivirus plugin is not blocking emails for whitelisted recipients (via autowhitelistforce-delivery or "Whitelisted Email TO")}

{TODO -cFix : Drastically improved SpamFilter ISP "standard" load time by a factor of x1000 when first importing large list of local domain names (10,000+ entries) }

{TODO -cNew : Added the option to install the web-based quarantine website directly from the SpamFilter Installer}

// New to VersionNumber = '4.0.1.784';

{TODO -cFix : The X-Rejection-Reason header was not added to spam emails when there was only recipient, and this address was in the Whitelisted EmailTO whitelist}

{TODO -cFix : The SPF settings for neutral, softfail and fail had the opposite values instead of the recommended defaults for new installations of SpamFilter in empty directories}

{TODO -cFix : During new installations, in SpamFilter ISP the "Custom Domain Filters" was not available due to an empty value in the "LocalDomainsFilterMatrixFileName" entry in the SpamFilter.ini file}

// New to VersionNumber = '4.0.1.782';

// New to VersionNumber = '4.0.0.774';

{TODO -cFix : When sending an NDR notification for a non-deliverable email, if the NDR also has delivery problems, these problems were note being logged, making it appear in the logs as if the NDR was successful}

{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 = '3.5.4.710';

{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 -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}
