I asked you to create a role for each address that you send mail 
From because:

1] The spam problem has made it difficult to *succussfully* send 
mail if your MAIL FROM address and your outgoing SMTP server do 
not match (*). I had you set up each of your roles in a way that 
the MAIL FROM and the outgoing SMTP server work well together, 
and mail sent using these roles will be less likely to be 
blocked by aggressive spam filters.

2] When you send mail using your Pine defaults, rather than a 
role, there is a chance that you will run into the mismatched 
MAIL FROM and SMTP problem.

Right now things seem to be working fine when you send mail with 
your Pine defaults, but it's possible that the default settings 
will NOT work on your other (non-titan) machines or if we make 
some configuration changes. When/if you have a problem sending 
mail, it will be very useful to you to have all your roles set 
up and ready to go! So don't delete them!

Does that make sense?
Let me know if you have a question,
