Why do I see traps when I enable the zip attachment handling in GMS Anti-Spam?

Question

Various issues have been discovered since the release of build 3213. These include traps in the SMTP service when the GMS Anti-Spam zip attachment handling options are enabled, and messages being rejected for containing mis matched CR or LF characters by SMTP.

Answer

A hotfix for both smtp.exe and ntmvpp.dll has been released to address both these issues. A complete list of items addressed is listed below.

1. smtp.exe – stops all mail being rejected with mis-matched CRLF characters if EnforceCLF set to a value of 2.
2. smtp.exe – stops dual scanning of attachments if Anti-Spam options to scan within the contents of zip files are enabled.
3. ntmvpp.dll – stops traps occurring if Anti-Spam zip file attachment handling options are enabled
4. ntmvpp.dll – allows punctuation to be correctly found if Raw HTML mode is enabled in the Restricted Content handling.

Both files should be obtained and updated on installations of Build 3213.

Note: Customers running GMS Anti-Virus will automatically receive the updated ntmvpp.dll as part of their Anti-Virus updates.
