I used to see sendmail rejections, too, like this in the maillog
of a Redhat 9 server:
    Milter: data, reject=451 4.3.0 Problem running virus-scanner

If you try to run uvscan from the command-line, it hangs forever.
This is a known problem with uvscan on Redhat 9 picking up the wrong
shared libraries, see

I now use this wrapper as /usr/local/bin/uvscan:

export LD_PRELOAD=/lib/libc.so.6
exec /usr/local/uvscan/uvscan $*
