[Dovecot] How do I configure sendmail to accept emails for dovecot when dovecot has sql auth/user db.

Included below are my config files: sendmail.mc, dovecot.m4,  
dovecot.conf, dovecot-sql.conf.  Whenever I try to send email into  
this system, it rejects it with user does not exist, however, the  
user does exist as far as dovecot (imap) is concerned, it is in the  
database.

THANKS - Yossie

Read the page you've quoted:
"Installation
Cyrus SASL"

There is no mention of Dovecot SASL.

======
You need to re-design your virtual user setup, e.g. use LDAP in 
combination with PAM.

Or, perhaps, patch in SQL support: http://blue-labs.org/software/sm-pgsql/
There is/was http://sourceforge.net/projects/sendmail-sql/.

Or, perhaps, make a Dovecot-SASL-patch for sendmail.

I'm using real users, so I don't know the functionality of those
patches.
If you search the Internet for sendmail+dovecot+sasl you'll see either no 
replies or "use postfix". There is a SASL-Patch for postfix.

Bye,
