Re: sasl seems to be ignoring my Sendmail.conf

Well, it seems that when sendmail calls the sasl library, the SASL_OK
is not being returned and so I get the authwarning: no mechanisms.  I
looked in the source of sendmail.  I could find no reference in that
source to Sendmail.conf at all. and yes, sendmail was compiled
correctly with sasl2.
