Crossware Mail Signature can operate in two different modes - Server Based Signatures and/ or Local Signatures. You can use both modes at the same time - for example you may choose to use Local signatures for personal information, and use server based signatures for disclaimers and advertisements.
Server Based Signatures
Server based signatures are where the signature is appended as the email passes through the server. This is done using an extension manager hook. The application is loaded as a dll/shared library/svrpgm by the domino server using the following notes ini variable:
Windows
EXTMGR_ADDINS=signature4_xx.dll (where x is the version)
UNIX
EXTMGR_ADDINS=signature
iSeries
EXTMGR_ADDINS=sig
Local Signatures
In Version 3 and above, the application can apply signatures to Notes Clients using an add-in task. The add-in task uses the same dll/sharded library/svrpgm as above.
The following notes ini variable is required:
Windows
CWSIGNATURELIBRARY=signature4_xx.dll (where x is the version)
UNIX
CWSIGNATURELIBRARY=signature
iSeries
CWSIGNATURELIBRARY=sig
