Some investigation confirmed my initial suspicions: that Cyrus lmtpd is returning to Postfix's lmtp delivery daemon the message: "sendmail: fatal: sender@xxxxxxxxxxx(76): Message file too big" Since that doesn't start with [2-5]\d\d, it's not a valid LMTP response, and Postfix is doing the right thing by complaining. Why would Cyrus return that? Obviously something is wrong with the delivery, but under what circumstances would a) lmtpd invoke the sendmail binary? b) sendmail fail thusly? c) lmtpd pass the failure message, unadorned, back to the sender? The latter in particular seems like broken behavior; shouldn't lmtpd return something like '5xx sendmail: fatal: ...'? There's plenty of free space everywhere, and message size limits are either set high or not at all. Any ideas? Thanks!
