v2.2.17 Segfault

Hi, I'm using libexec/dovecot/imap via a ssh tunnel. 2.2.17 segfaults while accessing a NULL pointer. The following change fixes it for me: --- dovecot-2.2.17/src/lib-imap/imap-keepalive.c 2015-05-03 11:12:11.000000000 +0200 +++ dovecot-2.2.17/src/lib-imap/imap-keepalive.c 2015-05-14 20:06:29.490617405 +0200 @@ -11,6 +11,8 @@ { unsigned int addr; + if (!ip) + return FALSE; if (ip->family == 0) return FALSE; if (ip->family == AF_INET) { Thanks, Adam -- Adam adam(a)os.inf.tu-dresden.de Lackorzynski http://os.inf.tu-dresden.de/~adam/

Pigeonhole v0.4.8.rc3 compilation error (bad mail-deliver.h)
by Jacques Distler 14 May '15

14 May '15

Got a /usr/local/include/dovecot/mail-deliver.h:30:17: error: field has incomplete type 'struct timeval' struct timeval delivery_time_started; ^ error. This is because mail-deliver.h in dovecot-2.2.17 is missing an #include <sys/time.h> Adding that line to mail-deliver.h fixes the problem. Oddly, I had no problem compiling dovecot itself.

http://dovecot.org/releases/2.2/dovecot-2.2.17.tar.gz http://dovecot.org/releases/2.2/dovecot-2.2.17.tar.gz.sig A few director improvements since RC2, some fixes and a new plugin: http://wiki2.dovecot.org/Plugins/QuotaClone * Dovecot no longer checks or warns if a mountpoint is removed. This was causing more trouble than it was worth. Make sure that all the mountpoints that Dovecot accesses aren't writable by mail processes when they're unmounted. * dict server wasn't properly escaping/unescaping data.

Released Pigeonhole v0.4.8.rc3 for Dovecot v2.2.17
by Stephan Bosch 14 May '15

14 May '15

Hello Dovecot users, RC2 had one more important bug caused by the new sieve_default_name feature. To prevent causing more of such rather stupid bugs in the future, I created an external shell-based test suite to test dovecot-lda delivery, the doveadm sieve tools and ManageSieve. These kind of tests aren't possible with the current Sieve-based test suite that is included in the Pigeonhole tarball. Now I can test most basic top-level Pigeonhole functionality in one go. Additionally, I created one new feature for ManageSieve. It allows logging various statistics at client disconnect, much like POP3 currently supports. This is e.g. useful for debugging. In the process, I fixed a few ManageSieve bugs as well. If RC3 doesn't cause any more issues, I will release 0.4.8 this Friday. Changelog v0.4.8 (updated): * LDA Sieve plugin: Dovecot changed the deliver_log_format setting to include %{delivery_time}. This prompted changes in Pigeonhole that make this release dependent on Dovecot v2.2.17. + Implemented magic to make sieve_default script visible from ManageSieve under a configurable name. This way, users can see the default rules, edit them and store a private adjusted version. This could also be achieved by copying the default script into the user's script storage, but updates to the global sieve_default script would be ignored that way. + ManageSieve: Implemented support for reporting command statistics at disconnect. Statistics include the number of bytes and scripts uploaded/downloaded/checked and the number of scripts deleted/renamed. - Fixed problem in address test: erroneously decoded mime-encoded words in address headers. - extprograms plugin: Fixed failure occurring when connecting to script service without the need to read back the output from the external program. - Fixed bug in script storage path normalization occurring with relative symbolic links below root. - Fixed and updated various parts of the documentation - ManageSieve: Used "managesieve" rather than "sieve" as login service name, which means that all managesieve-specific settings where ignored. - Managesieve: Storage quota was not always enforced properly for scripts uploaded as quoted string. Nobody uses that, but it is allowed in the specification and we support it, so it should work properly. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.8.rc3… http://pigeonhole.dovecot.org/releases/2.2/dovecot-2.2-pigeonhole-0.4.8.rc3… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information.

dovecot-lda panics when postmaster_address is given on command line
by Onno Molenkamp 13 May '15

13 May '15

Hi, When passing a postmaster_address to dovecot-lda on the command line with -o, it panics: $ ./dovecot-lda -o postmaster_address=anything lda(onno,)Panic: file lda-settings.c: line 80 (lda_settings_check): assertion failed: (set->postmaster_address[0] == SETTING_STRVAR_UNEXPANDED[0]) It looks like postmaster_address has already been expanded at that point when it's given on the command line. (set->postmaster_address[0] is "1") I'm running v2.2.15, but with v2.2.17.rc1 the same thing happens. Regards, Onno

Re: Dovecot is not reading connections from iOS devices correctly. Any ideas?

Some mail readers have auto-discover features that are rather stupid. If possible, manually configure the SSL style (TLS/STARTTLS) and port rather than letting it guess. To diagnose whether it is some dovecot config error, you can manually connect with both flavours of SSL openssl s_client -connect 192.168.0.15:993 ... or ... openssl s_client -starttls imap -connect 192.168.0.15:143 then if it gets past the SSL handshake, a login <user> <password> to test the authentication part. This will at least tell you whether it's a client side or server side issue. (However, since it is working with other client, it's probably a client side issue.) Joseph Tam <jtam.home(a)gmail.com>

Released Pigeonhole v0.4.8.rc2 for Dovecot v2.2.17.rc1

Hello Dovecot users, Ok, RC1 contained one rather stupid bug that caused a segfault at delivery. It was caused by a new feature, so the list of changes is not updated.
