[Dovecot] dovecot + sendmail, what LDA setup?

I have an existing setup with sendmail, dovecot, on debian.
 I want to move LDA and move from using mbox to using 

Maildir. I have only 'real' users and aliases, no virtual users. What is a recommended, trouble free, LDA setup? procmail is of course on possibility, but I'd be unlikely ever to use any of its advanced features, just simple local mail delivery. I'd like to use deliver, but most of the dovecot as LDA sample configs I have seen seem to assume I am using it for virtual users. Advice? Pointers to a simple working setup for sendmail, dovecot, Maildir? Cheers David
