The following table lists the registry settings that have been added for SSL support under the base registry key HKEY_LOCAL_MACHINE\COMM\HTTPD\SSL.

Value : type Description

IsEnabled: REG_DWORD

If the value is not set in the registry, IsEnabledwill default zero (0). Set this value to nonzero to enable. If this value is set to zero (0) or does not exist, SSL will not be enabled on the Web Server.

Port: REG_DWORD

If the value is not set in the registry, Portwill default to 443.

Specifies the port that is used to receive SSL connections. It is recommended that this value not be changed under normal usage.

CertificateSubject: REG_SZ

Default value is not set in the registry.

Specifies the subject of the certificate that the server will use. This certificate should already be installed under "MY" cert store when the Web Server starts. If this certificate cannot be loaded, SSL will not be enabled and an error message will be written out to the log file.

You can also disable automatic SSL probing by configuring the HKEY_LOCAL_MACHINE\Software\Microsoft\Inboxregistry key.

Value : type Description

DisableAutoSSL: REG_DWORD

When set to a non-zero value, SSL probing in POP3/IMAP is bypassed when the ‘Require SSL Connection for Incoming E-mail’ checkbox is unchecked. Similarly, SSL probing in SMTP is bypassed when the ‘Require SSL Connection for Outgoing E-mail’ checkbox is unchecked.

When set to 0 or not set, SSL probing is done for POP3/IMAP & SMTP even if the ‘Require SSL Connection for Incoming & Outgoing E-mail’ checkbox is unchecked.

By default the value is not set
