help filtering messages
by James 23 Oct '15

23 Oct '15

Hello, I'm attempting to use sieve-filter on a local mailbox. I've defined mail_location as follows: % grep mail_location /etc/dovecot/conf.d/10-mail.conf mail_location = maildir:~/Mail I have a large number of mailboxes / mail in ~/Mail: ~ % find Mail | wc -l 63158 There are definitely a few messages in INBOX: ~ % find Mail/INBOX/cur | wc -l 5 I must admit, I'm completely new to sieve and have just begun experimenting with it. Based on a super helpful blog post[1], I quick set up the following ~/.sieve: % cat ~/.sieve require ["fileinto"]; # rule:[TEST] if header :contains "Subject" "Test Email" { fileinto "TEST"; stop; } As mentioned, there are numerous emails in INBOX. This email is located in ~/Mail/INBOX/cur/<blah> and, for verbosity (and to ensure I'm not making a foolish mistake), I've displayed it here: From: Test Account <test(a)test.com> To: "Me" <me(a)test.com> Subject: Test Email Date: Mon, 19 Oct 2015 14:55:06 +0000 This is a test email. Looking at the sieve filter recipe and email message, it appears that I should have a match, no? sieve-filter appears to disagree: % sieve-filter -C ~/.sieve INBOX sieve-filter(test_user): Debug: Effective uid=1000, gid=1000, home=/home/test_user sieve-filter(test_user): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:~/Mail sieve-filter(test_user): Debug: maildir++: root=/home/test_user/Mail, index=, indexpvt=, control=, inbox=/home/test_user/Mail, alt= Thinking this was because sieve will only filter on new messages, I moved the file from cur to new. No change. Any thoughts on why this may be happening? Thanks! 1 https://mebsd.com/configure-freebsd-servers/dovecot-pigeonhole-sieve-filter…

Hibernation disabled when mailbox selected
by Joseph Tam 20 Oct '15

20 Oct '15

After setting imap_hibernate_timeout to 60s, I could not find any hibernated connections after a few hours. I tested hibernation and made an observation: IDLE'd imap sessions only hibernate if they don't have a mailbox SELECT'd, otherwise they never hibernate. Is this the way it's supposed to work?

TLS communication director -> backend with X.509 cert checks?
by Heiko Schlittermann 19 Oct '15

19 Oct '15

Hello, using Dovecot 2.2.9 and a setup with directors and backends. The communication between directors and backends needs to be TLS secured. The director config contains a list of hostnames for the backends. (implicit list because of multiple A/AAAA records for a single hostname or explicit list of several host names) On connection setup from a client the director connects to the selected backend. But it seems (not checked in the source yet), that for SSL certificate verification the director doesn't know the original host name anymore. The certificate's CN gets compared to the IP address the director connects to. Oct 12 23:56:51 director2 dovecot: director: Error: director(2001:683:921:f33::5:1:9090/out): connect() failed: Connection reset by peer Oct 12 23:57:53 director2 dovecot: imap-login: Error: proxy: hostname doesn't match SSL certificate at 2001:683:921:f33::5:fe:993: user=<foo>, method=PLAIN, rip=2001:638:912:f33::1:1, lip=2001:638:912:f33::5:2, TLS, session=<fLrUa+8hggAgAQY4CRIPMwAAAAAAAQAB> In 10-directors.conf I've: director_mail_servers = backend1.<domain> backend2.<domain> Should I create certificates with IP address in SAN? (Any hint about the correct syntax for the openssl.conf is welcome). Or is there any chance that this is fixed already or will be fixed in the near future or even better, that it's my fault?
