Help modifying bb-services

[Robert Bethke <r4bethke+HobbitMail (at) wmich.edu>]

I'm currently working on a project that I need to get hobbit to test 
authentication on a number of servers namely an IMAP and SMTP server, along 
with a few others. I was guessing having little background in network 
diagnostic that I could modify the sent responses within bb-services to login 
to the server using a test account and then check for the proper response 
back. The problem I've run into is that I'm not clear on the proper commands 
or syntax to do this and when I have modified the tests it seems that I'll 
get a green event regardless to what I put within expect. Anyway if anyone 
could point me in the right direction (Examples are great too) it would be 
greatly appreciated.

Thanks,
