[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.

[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. The guys at the ISP have sent me the full error they are getting on their Exim SMTP server.

Hello, i use a globalsieve rule to collect spam for all mail accounts in a specific mailbox. Here is the code: vi /var/vmail/globalsieverc require ["fileinto"]; # Move spam to junk folder if not address :is "to" "antispam(a)xxx.com" { if header :contains "X-Spam-Flag" ["YES"] { redirect "antispam(a)xxx.com"; stop; } } But the spam mails are not delivered. cat /var/log/mail.info postfix/pipe[32301]: AD8F78E2128D: to=<antispam(a)xxx.de>, relay=dovecot, delay=0.14, delays=0.08/0/0/0.06, dsn=5.4.6, status=bounced (mail forwarding loop for antispam(a)xxx.de) Why is there a loop?

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

[Dovecot] Corrupted index cache file and high CPU usage
by hydra 24 Dec '11

24 Dec '11

I suspect, that dovecot v2.0.16 under Linux (tested on Gentoo 3.0.4 Hardened, Gentoo 3.0.6, Gentoo 3.1.4) causes 100% cpu utilization when index.cache is broken and doveadm is lanched. Dovecot uses LDAP as the userdb and provides IMAP and LDA. Because each user has a quota, the doveadm's expunge functionality is used to get rid of old trashed mail. The mail log: Dec 12 07:38:59 www dovecot: imap(user): Error: Corrupted index cache file /var/data/mail/domain.tld/user/mail/dovecot.index.cache: invalid record size Doveadm is launched as: doveadm -D expunge -A mailbox Trash savedbefore 1w Mail is stored on ext4 and flush will use all of the CPU capacity like this: load average: 4.00, 4.01, 4.05 ps: root 26401 98.2 0.0 0 0 ?

When this happens, I cannot unmount the drive nor a system reboot works. Thank you !
