Dear all, when I send myself a message without a body, lmptd gets stuck --- it eventually times out with a "451 4.3.0 System I/O error" and subsequent messages through the same LMTP connection fail as well.
My setup is Cyrus 2.1.3, Debian postfix 1.1.6-1, configured to deliver mail via unix sockets through LMTP, as outlined in several example configurations. Things work very well, except for messages which I can (re)create by talking SMTP to postfix and sending a message like this: $ telnet mymailserver smtp Trying x.x.x.x... Connected to mymailserver Escape character is '^]'. 220 mymailserver ESMTP Postfix (Debian/GNU) helo myclient 250 mymailserver mail from: <[EMAIL PROTECTED]> 250 Ok rcpt to: <roehrig@mymailserver> 250 Ok data 354 End data with <CR><LF>.<CR><LF> From: [EMAIL PROTECTED] To: roehrig@mymailserver . 250 Ok: queued as B0708C33D3 quit 221 Bye Connection closed by foreign host. My next attempt will be to look up the basics of LMTP and try to talk LMTP directly with Cyrus lmtpd, but perhaps somebody can already tell me whether a null body makes a legal message? If not, then a more meaningful lmtpd error message would be very helpful. Thanks in advance for any advice, Hein
