I must say the output shown does not look like a pipeline at first 
glance. It resembles a normal SMTP session but they have a problem with 
multiple line responses.

RFC 5321 indicates that the use of HELO is now deprecated. But even RFC 
821 specifies that multiline responses are allowed for each valid command.

Perhaps someone ought to print out those RFCs, roll them up real stiff 
and whack these guys over the head with it?
