filtering ssl_cert
by Russell Stuart 30 Jun '16

30 Jun '16

In dovecot 1 I was able to do something like this: protocol imap { ssl_cert = cert-imap.pem ssl_key = key-imap.pem } local ww.xx.yy.zz { protocol imap { ssl_cert = cert-imap-ww.xx.yy.zz.pem ssl_key = key-imap-ww.xx.yy.zz.pem } } The intent is ww.xx.yy.zz is an externally routable IP address which has a Cert signed by a real CA, other addresses are internal which have a variety of domain names, signed by a self-signed cert. That worked in dovecot 1, but in dovecot 2 I get the error: "Conflict in setting ssl_cert found from filter". Weirdly, this works in dovecot 2: local 0.0.0.0/0 { ssl_cert = cert-imap.pem ssl_key = key-imap.pem } local ww.xx.yy.zz { ssl_cert = cert-imap-ww.xx.yy.zz.pem ssl_key = key-imap-ww.xx.yy.zz.pem } But this doesn't: local 0.0.0.0/0 { protocol imap { ssl_cert = cert-imap.pem ssl_key = key-imap.pem } } local ww.xx.yy.zz { protocol imap { ssl_cert = cert-imap-ww.xx.yy.zz.pem ssl_key = key-imap-ww.xx.yy.zz.pem } } It smells like a bug. Anyway, does anybody know of a way to port my config to dovecot 2?

Error when searching in mailfolders
by Christoph Pleger 30 Jun '16

30 Jun '16

Hello, I just found that with my dovecot 2.2.21, when I use squirrelmail to search for something in my mailfolders, that fails with ERROR: Connection dropped by IMAP server. Query: SEARCH CHARSET ISO-8859-1 ALL FROM "someone" That happens for searches in any folder, except from INBOX. When I search in all folders, only results from INBOX are found, then the error message is shown. The log says: imap: Error: terminate called after throwing an instance of 'CLuceneError' imap(christoph): Fatal: master: service(imap): child 2834 killed with signal 6 (core dumps disabled) What can I do about that? Regards Christoph

SSL Problem with -git master-2.2 tip (24 June 16)
by Reuben Farrelly 30 Jun '16

30 Jun '16

Current master-2.2 branch of Dovecot compiles for me on Gentoo x86_64 but experiences symbol errors when starting up: Jun 24 08:38:00 thunderstorm dovecot: lmtp(8180): Fatal: Couldn't load required plugin /usr/lib64/dovecot/libssl_iostream_openssl.so: dlopen() failed: /usr/lib64/dovecot/libssl_iostream_openssl.so: undefined symbol: SSL_COMP_free_compression_methods Jun 24 08:38:00 thunderstorm dovecot: master: Error: service(lmtp): command startup failed, throttling for 16 secs I suspect that this is because I have libressl installed on my systems instead of OpenSSL. A known commit point which does not work is: f5e6b05684328b9800ccd973c73027300c832d65 However a few commits earlier this problem does not occur: f292589f4b85e02d97d974dfe34324c6c0bb9d9f Looks like commit bff052bd29dbf7175ee6cd14bd14bcea1900b869 : "lib-dcrypt, lib-ssl-iostream: Share OpenSSL init/deinit code." may have broken the tree for LibreSSL/non OpenSSL users.

[patch] Fix for returning NULL values in SQL dict lookups
by NederHost/Sebastiaan Hoogeveen 29 Jun '16

29 Jun '16

Hi, I noticed a bug doing dict lookups on an SQLite database which had NULL values in its columns; a segmentation fault occurred, probably due to a null pointer dereference in str_tabescape. The problem is that sqlite3_column_text returns a null pointer for column values which are (SQL) NULL. It seems the other database drivers do something similar. The following patch makes the dict server check for null pointers and return a 'not found' reply in those cases (I changed the order around in the decision tree to avoid having to repeat return values): diff -Naur dovecot-2.2.24/src/dict/dict-commands.c dovecot-2.2.24-patched/src/dict/dict-commands.c --- dovecot-2.2.24/src/dict/dict-commands.c 2016-04-26 15:01:20.000000000 +0200 +++ dovecot-2.2.24-patched/src/dict/dict-commands.c 2016-05-11 22:04:06.000000000 +0200 @@ -83,14 +83,14 @@ { struct dict_connection_cmd *cmd = context; - if (result->ret > 0) { + if (result->ret > 0 && result->value) { cmd->reply = i_strdup_printf("%c%s\n", DICT_PROTOCOL_REPLY_OK, str_tabescape(result->value)); - } else if (result->ret == 0) { - cmd->reply = i_strdup_printf("%c\n", DICT_PROTOCOL_REPLY_NOTFOUND); - } else { + } else if (result->ret < 0) { i_error("%s", result->error); cmd->reply = i_strdup_printf("%c\n", DICT_PROTOCOL_REPLY_FAIL); + } else { + cmd->reply = i_strdup_printf("%c\n", DICT_PROTOCOL_REPLY_NOTFOUND); } dict_connection_cmds_flush(cmd->conn); } Kind regards, -- Sebastiaan Hoogeveen NederHost https://www.nederhost.nl/ KvK: 34099781
