We have a situation which I have not really seen before, we have 8.0.2 on the back-end servers, running NetWare 6.5 SP8, when a user from the field (we are currently only seeing this in the field) sends a file with an extension (for example index.html) to an external user the file is sent normally, if the user sends the file to someone on the same post office the file case is retained, however; when they send that file to a user on a different post office (within the same Domain) the file extension case gets changed from index.HTML any ideas why or how this could be happening? I can provide further information as needed.
