How to check if GFI MailEssentials is in Active Directory (AD) or SMTP mode

Answer

Information regarding whether the install was done in SMTP mode or AD mode can be found in the registry. It is possible to open regedit to obtain this information or review the Trouble.txt log if Troubleshooter data has already been gathered.

MailEssentials Registry Key:

• X64 bit [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\GFI\MailEssentials\Antispam\CONFIG]
• X86 bit [HKEY_LOCAL_MACHINE\SOFTWARE\GFI\MailEssentials\Antispam\CONFIG]

The Modetype key will show what mode the install is in while the Modexch key will display where MailEssentials is installed.

Modetype:

• 0: Users retrieved from AD
• 2: Users not retrieved from AD (SMTP mode)

Modexch:

• 0: Not installed on Exchange (relay)
• 1: Installed on Microsoft Exchange 2000
