I would question that these failures are in fact related to what 
Sendmail is doing. Does Sendmail even support Dovecot SASL? AFAIK it 
does not, therefore there is no way that Dovecot could possibly 
interfere with SMTP AUTH in Sendmail.

And you are jumping to conclusions. I suggest that you take this 
matter to a Sendmail forum. When you do, provide all relevant 
configuration as well as complete logging to show the problem. No 
useful help is possible with what you posted here.
