[Dovecot] Received date no longer email date?
by Brian L. Matthews 29 Dec '11

29 Dec '11

I just upgrade from dovecot 1.2 to dovecot 2.0.16. I use dovecot as a local IMAP server to archive email from my corporate email account (on Exchange). I don't have any automated archiving, I just periodically move messages from my Exchange inbox to the IMAP inbox. I'm on Mac OS X 10.6.8 using Entourage as my mail client. In the previous version of dovecot, the Received date of the email was preserved when I moved a message, but it's not in 2.0.16, it's set to the date and time I move the message. If I open a message, the date displayed is the date on the message as expected. I converted my config from 1.2 with $ doveconf -n -c dovecot.conf > dovecot-2.conf It spit out various warnings but, once I'd created a dovenull user, seemed to work fine. Here's my configuration info: $ dovecot --version 2.0.16 $ dovecot -n # 2.0.16: /usr/local/etc/dovecot/dovecot.conf # OS: Darwin 10.8.0 i386 disable_plaintext_auth = no listen = 127.0.0.1 log_path = /var/log/dovecot.log mail_location = maildir:~/Maildir passdb { args = login driver = pam } service auth { user = root } service imap-login { process_limit = 16 } service imap { process_limit = 64 } ssl = no userdb { driver = passwd } I'd like to get it back to preserving the Received date, any help you can provide will be appreciated.

[Dovecot] proxying, SSL, and client certificate
by Mike Abbott 29 Dec '11

29 Dec '11

How do I configure dovecot-2.0.x to present a client SSL certificate when proxying? If dovecot on server1.example.com has: passdb { driver = static args = proxy=y host=server2.example.com nopassword=y ssl=yes } and dovecot on server2.example.com has: ssl_verify_client_cert = yes auth_ssl_require_client_cert = yes then when a client connects to server1 and authenticates, a connection is established to server2 but the SSL handshake fails because server1 doesn't present a client certificate. I don't see where ssl_client_ctx is tied to a client certificate in ssl-proxy-openssl.c. Thanks.

For a single server, is the Lucene backend now "better" than running a Solr server? -- Daniel

[Dovecot] Dovecot imap proxy to nginx, incompatible
by David Jonas 29 Dec '11

29 Dec '11

It appears that using dovecot to proxy to nginx imap proxy doesn't work. >From tcpdump and browsing the source it appears dovecot sends, C CAPABILITY\r\nL LOGIN <user> <pass>\r\n and nginx only responds to the CAPABILITY command. Is this a problem with dovecot sending the two commands without waiting for the first to complete or is it nginx's trouble with not handling it correctly? A quick test with a perl script confirms: #!/usr/bin/perl -w $|++; use IO::Socket; use strict; my ($host, $user, $pass) = @ARGV; my $s = new IO::Socket::INET(Proto => 'tcp', PeerAddr => $host, PeerPort => 143); die "Could not create socket $!\n" unless $s; while(<$s>) { print $_; last if /OK/; } print $s "C CAPABILITY\r\nL LOGIN $user $pass\r\n"; while(<$s>) { print $_; last if /OK/; } print $s "Q logout\r\n"; while(<$s>) { print $_; last if /OK/; } close($s); ## Output: * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS UIDPLUS LIST-EXTENDED I18NLEVEL=1 QUOTA AUTH=PLAIN C OK completed * BYE Q OK completed

Dear all, I have been trying to get this problem out of the way but I just cant seem to get it right. I hope someone can point me in the right direction here. I have come up with a vacation script as below, which can be send out from my Postfix SMTP server to my smarthost at the ISP, and yet for some reason it is not sent out at my ISP server.

With dovecot2 and pigeonhole sieve/managesieve is it currently possible to store sieve rules in an sql database? If not is there a way to query all accounts; looking for things like active vacation rules? Regards, Bradley Giesbrecht
