confused about BDB directory layout in imapd
There are these files/directories in cyrus-imapd: /var/lib/imap/deliver.db /var/lib/imap/mailboxes.db /var/lib/imap/tls_sessions.db /var/lib/imap/db/* The /var/lib/imap/db/ directory, however, seems to hold no database: -rw---1 cyrusmail 8192 2004-01-08 18:02 __db.001 -rw---1 cyrusmail 270336 2004-01-08 18:02 __db.002 -rw---1 cyrusmail98304 2004-01-08 18:02 __db.003 -rw---1 cyrusmail 18563072 2004-01-08 18:02 __db.004 -rw---1 cyrusmail32768 2004-01-08 18:02 __db.005 -rw---1 cyrusmail 1637827 2004-01-12 09:48 log.03 Now, some practical questions: - if I run db_recover in /var/lib/imap/db, which database will be recovered? - if I run db_recover in /var/lib/imap (which holds deliver, mailboxes and tls_sessions), again, which database will be recovered? - why can't I run db_checkpoint? Where should I? Or should I stick with the ctl_cyrusdb tool?

roadmap of 2.2 branch

BDB or skiplist?
I see that the cyrus-imap-2.2 branch already uses skiplist as the default format. Does this recomendation also apply to the 2.1 branch or was this due to some code change between 2.1 and 2.2?

Check hoststat and see if your localhost entry is reporting an error, like Connection Deferred, etc. What I've had to do is kill all the sendmail instances trying to deliver to localhost, restart sendmail, restart cyrus, purgestat (clear sendmails database of delivery success/failure). At that point, delivery will start up again. I've also set the hoststatus timeout to be 5 minutes instead of the default 30minutes, in sendmail.mc/cf but it doesn't seem to help. The only other thing that is in the mix is I'm running MailScanner to process e-mails for spam and virii, but sendmail and cyrus are all local, so I don't know why cyrus and sendmail think the ltmp socket isn't available.

SSL/TLS question
[Sorry this is a repost from a month ago; I didn't get an answer then, but maybe my timing is better now.] For my web server, I use a certificate from Comodo which is very inexpensive by comparison with Thawte/Verisign certs, but it requires installation of an intermediary key for most browsers to be happy with it. It's not difficult with Apache and mod_ssl; I'm wondering if it will work with Cyrus, perhaps using the 'tls_ca_file'? The docs are a little sparse (and Comodo doesn't provide explicit instructions like it does for mod_ssl) and my understanding of SSL/TLS is a bit limited.

Re: Adding Users
Norman Zhang wrote: Oh okay. I disable port 143 (imap) in favor of 993 (imaps). Does cyradm only connects to 143? Cyradm wants to use port 143/tcp - AFAIK it doesn't support IMAPs. Try running an IMAPd for standard IMAP that only talks to the loopback interface. For more information on how, please check the archives or man cyrus.conf. Craig Ringer

The docs are a little sparse (and Comodo doesn't provide explicit instructions like it does for mod_ssl) and my understanding of SSL/TLS is a bit limited. I expect that'd do it; you'll still need to install the CA certificate in browsers, though. I have a similar setup, but with a CA cert generated in-house. My imapd.conf contains: tls_ca_file: /var/imap/ssl/ca.pem tls_cert_file: /var/imap/ssl/mail.postnewspapers.com.au_cert.pem tls_key_file: /var/imap/ssl/mail.postnewspapers.com.au_key.pem - the filenames are somewhat self explanatory (though your key and cert may be combined into one file). I then install the ca cert into clients who need access. To be specific, I generate a client SSL certificate for them that also contains an embedded version of our CA cert. That way they import the CA cert when they install the client cert; I then just get them to authorize the CA cert for identifying remote hosts. Craig Ringer
