Provider Property (MailJob)

In This Topic

This option can be used to switch the mail provider. All options besides MSMAPI need the mail module (cmmx??.dll (32-bit) or cxmx??.dll (64-bit)).

Value	Meaning
SMAPI	Simple MAPI
XMAPI	Extended MAPI
MSMAPI	System MAPI (using the default MAPI client)
SMTP	Sending mail via SMTP (see AdditionalOptions for connection data)
GRAPH	Microsoft Graph API e.g. for the Office 365 Cloud (for connection data see AdditionalOptions) For using the GRAPH provider additional files are needed: - combit.ListLabelXX.GraphMailExtension.dll - combit.ListLabelXX.MailExtensions_x86.dll or combit.ListLabelXX.MailExtensions_x64.dll - The content of the associated Microsoft.Graph subfolder
Default	The default value depends on the system's or application's settings (see below)

If the DLL can not be found, the mail will be sent using system MAPI (MSMAPI). The provider is selected by either setting it explicitly using this option or letting the user choose in the LsMailConfigurationDialog(). List & Label tries first to retrieve the application specific mail settings from the registry. If those can not be found, the global mail settings will be applied. These can be set using LsMailConfigurationDialog().
