Hello, I'm trying to configure Cyrus imap v 2.2.12 with SSL. It works ok when using a self signed certificate that is in pem format. But, when I configure it to use the certificate we purchased from Comodo, I have problems. I am testing the key using the command "openssl s_client -connect foobar:993", and I get an "unknown protocol" error. I ran the openssl command in debug mode, and at the same time ran tcpflow on the imap server. The tcpflow has a message "enter PEM passphrase". When I created the private key and csr I had to enter a passphrase because it wouldn't let me keep it null. Could this be part of the problem? How do I fix it? Any help would be greatly appreciated as I'm new to imap and ssl. Below is some output that may be helpful: This is the command I'm using to test the certificate and the error that I get: [EMAIL PROTECTED] certs]# openssl s_client -connect foobar:993 CONNECTED(0003) 24518:error:140770FC:SSL routines:SSL23 _GET_SERVER_HELLO:unknown protocol:s23_cl nt.c:475: This is output of the openssl command in debug mode, and the tcpflow: [EMAIL PROTECTED] certs]# openssl s_client -debug -connect foobar:993 CONNECTED(0003) write to 0907B310 [0907B358] (142 bytes => 142 (0x8E)) - 80 8c 01 03 01 00 63 00-00 00 20 00 00 39 00 00 ..c... ..9.. 0010 - 38 00 00 35 00 00 16 00-00 13 00 00 0a 07 00 c0 8..5 0020 - 00 00 33 00 00 32 00 00-2f 03 00 80 00 00 66 00 ..3..2../.f. 0030 - 00 05 00 00 04 01 00 80-08 00 80 00 00 63 00 00 .c.. 0040 - 62 00 00 61 00 00 15 00-00 12 00 00 09 06 00 40 b..a...@ 0050 - 00 00 65 00 00 64 00 00-60 00 00 14 00 00 11 00 ..e..d..`... 0060 - 00 08 00 00 06 04 00 80-00 00 03 02 00 80 c8 ee 0070 - 81 dc 07 4f 07 79 10 0f-a3 a0 5a 84 ca 3b b0 05 ...O.yZ..;.. 0080 - 22 fc c8 b6 75 ee 2b 9a-1c 79 46 51 13 4e "...u.+..yFQ.N read from 0907B310 [090808B8] (7 bytes => 7 (0x7)) - 45 6e 74 65 72 20 50 Enter P 25977:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:475: [EMAIL PROTECTED] etc]# tcpflow -i eth0 -c tcp and port 993 tcpflow[5999]: listening on eth0 123.45.67.89.35902-123.45.67.90.00993: ..c... ..9..8..5 .3..2../[EMAIL PROTECTED] 123.45.67.90.00993-123.45.67.89.35902: Enter PEM pass phrase: My /etc/imapd.conf file contains these lines: tls_cert_file: /usr/share/ssl/certs/imap-server.crt tls_key_file: /usr/share/ssl/certs/imap-server.key tls_ca_file: /usr/share/ssl/certs/ca-bundle.crt Thanks!

Re: checking quota

This technique works with Smail (which I use), and probably with minor adaptation with Exim, and maybe Postfix as well; though of course the specific format of the alias file will no doubt differ for those other mailers. As others have said already you could also use LMTP, but that would mean opening an LMTP connection (or re-using a cached connection) for every incoming SMTP transaction (which specified any locally deliverable recipient) so that the recipient could be verified. -- Greg A.
