The shared file system uses IUCV for its communication.  Mailer also uses IUCV
for its communication.  Fullscreen CMS also uses IUCV to trap console output.
For all of these to operate successfully within a CMS server the CMS IUCV
progamming interface must be used (not the former method of declaring a
private IUCV buffer and just communicating with CP).

As you can guess, Mailer does not use CMSIUCV so it behaves badly.  This
problem should have surfaced if Mailer was run under fullscreen CMS (which was
unlikely).

The macros (and CMS function) needed to be a good citizen were introduced in
CMS 5.  Once these changes are made Mailer will no longer work on releases
earlier than CMS 5.  I mention this here so that sites still running CMS 4
will be forwarned.
