One approach

step 1: make sure packages 'expect' and 'telnet' are installed
step 2: read: man autoexpect  and RFC 2821
... see worked example for handing email to a remote server

step 3: experiment to taste in talking the protocol.  'expect'
 	and autoexpect makes it trivial to build a script that
 	works
