I just succeded in getting kSpam to work on a linux server with Domino 7.
Let us try and piece together what you need to do on Linux to get it to work.
Her is what I did:
Find the Linux kSpam kit and extract.
copy two files to the/opt/ibm/lotus/notes/7000/linux/ directory. The files are:
kspam
libkspam.so
For both these files I changed the properties so that the same users/groups had exactly the same rights for the new files as they have for other files in the same directory. I'm thinking about read/write, execute and the like.
Then I opened notes.ini (located in the domino root directory - same directory as names.nsf) and made sure that I had the following:
ServerTasks=…,kspam
Extmgr_addins=libkspam.so
The above items are what are special for the Linux installation. The rest is the same as for the Windows-variant.
Above, where I put in a path -/opt/ibm/lotus/notes/7000/linux/ - you should of course change the path to point to your similar directory. The directory contains a number of files labelled something.so.
