I believe that's a misconception. Unlike qmail/exim/postfix, sendmail does not do local delivery. It hands it off to procmail. On a default RH install promail is set up to use mbox because the IMAP/POP server included (UW-IMAP) doesn't by default support maildir. By replacing the IMAP/POP server (ie. qpopper, Courier, etc.) you can set up procmail to use maildir and the performance should get better. At least that has been my experience, YMMV. -- Brian Ashe CTO Dee-Web Software Services, LLC.
