For clustering only me and the mailHost attribute in the ldapdb are used. If me != mailHost forward to mailHost else local delivery. If there is no mailHost then always do a local delivery. (more)rcpthosts steers only qmail-smtpd so it (almost) does not matter what you have in it. locals is used by qmail-send to find out if it is a local delivery or a remote delivery. clustering is only done on local delivery so if your qmail setup is OK clustering will work. NOTE: pay attention with me and mailHost. If mailHost is a CNAME of me you will have detected mail loops and even worse undetected imap/pop3 loops. -- :wq Claudio
