My SPF record originally only had mx and my ip block (Which contains  
all my servers).  Had no problems for 2 years.  A week or two ago a  
user complained one domain (some programmers domain which I thought  
was amusing) was rejecting based on SPF, and it turns out they only  
worked with the 'a' listing in there.  They were running Exchange..  
Just an FYI.. cover all your bases :/
