DLLHOST.EXE consuming 100 % of CPU on WWP server.

DLLHOST.EXE consuming 100 % of CPU on WWP server.



Ensim no longer supports MailMax, please contact SmartMax for assistance.

When a mail comes with the following string ( =?XX? where XX can be 2 or more characters ) in the subject field then the DLLHOST.exe would go to 100% if the mail was accessed via webmail.

Smart Max has released a patch to address this particluar issue.

Installation Instruction:

1. Stop IIS

2. Unzip the attached zip files ( messagetop.html & mmweb.dll )into the mailmaxweb directory which is normally there under c:\inetpub\wwwroot\Mailmaxweb.

3. Restart IIS.


You must have MailMax\Web version 4 on your server. This patch is not intended for any other version of MailMax\Web or third party mail servers
