the smbclient(1) has a missing space:
"One useful trick is to cat the message throughsmbclient."
Its the same problem as described in #3146
<para>One useful trick is to cat the message through
<command>smbclient</command>. For example: <command>
cat mymessage.txt | smbclient -M FRED </command> will
send the message in the file <filename>mymessage.txt</filename>
to the machine FRED. </para>
Just move the first <command> to the first line should fix this problem.
