Because I had a similar problem to yours and it worked for me.  I found 
a page instructing me on how to configure SASL and Sendmail and it 
showed using options a, y, and p, instead of the A, y, and p I had.  So 
I switched it, and it worked.

Here are the two documented settings:

A
    Use the AUTH= parameter for the MAIL FROM command only when
    authentication succeeded. 
a
    protection from active (non-dictionary) attacks during
    authentication exchange. 

Frankly I don't understand how either of this affect the success or 
failure of authentication.  A looks like it is only applicable for 
outgoing mail, whereas we're concerned about incoming mail.  The 
definition of 'a' seems a bit vague; what does this protection involve?  
But this does pertain to the authentication exchange, so theoretically 
it could affect its success or failure.
