"LDAP master" configuration of cyrus IMAP and sendmail does make sense especially with "mailbox auto create patch *BUT* 1) socket map daemon provides also "mailbox over quota" hint to MTA (sendmail) for use in "RCPT TO:" replies 2) cyrus virtual domains can be integrated in "nicer" with LDAP way even without quota check at MTA level 3) I insist on supporting *mixed* mailbox types e.g. with *most* mailboxes in cyrus but *some* mailboxes serviced by "classic local mailer". IMHO it makes sense to deliver messages to postmaster/abuse to cyrus and to local "mailbox agent" (procmail) and classic mailbox file. -- [pl2en: Andrew] Andrzej Adam Filip : anfi@xxxxxxxxxxxx : anfi@xxxxxxxx Home site: http://anfi.homesite.net/ ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
