Dovecot 2 Issue
by Peter Fraser 10 Mar '16

10 Mar '16

Hi All I have had a Dovecot-1.x Server running without issue for about 5 years now. I decided to set up a new Server and configure version 2 from scratch. I am having a little issue though. Set up on FreeBSD 10.2 Using dovecot2-2.2.21_1 Dovecot starts up but isn't listening on pop3 and imap ports. Not sure what I have missed. My dovecot -a readout is below. Thanks for any help. root@SMTP1:/home/frank # doveconf -a # 2.2.21 (5345f22): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.12 (c1c0a23) # OS: FreeBSD 10.2-RELEASE-p9 amd64 # NOTE: Send doveconf -n output instead when asking for help. auth_anonymous_username = anonymous auth_cache_negative_ttl = 1 hours auth_cache_size = 0 auth_cache_ttl = 1 hours auth_debug = yes

Using dsync to synchronize laptop against remote server
by Dato Simó 10 Mar '16

10 Mar '16

Hello! I’m thinking of changing the way I sync mail to my laptop, and I have a couple questions about my intended setup. In brief, my plan is: instead of running offlineimap against various IMAP accounts (my personal one included), I will run fetchmail on my private server, and classify mail with Sieve there. Then I’ll run a local Dovecot on my laptop, and do a master/master replication from my personal server/account with dsync. I have two quick questions about this (I have never used dsync before): 1. Reading the manual page, it seems that I probably want stateful synchronization (-s flag). Not having used it before, I’m curious about what lag I can expect. Does it compare to an IMAP IDLE/IMAP NOTIFY connection? Or is it asynchronous / with a timer? 2. I assume modifying my local Maildirs with e.g. Mutt is... a big no-no? Instead, should I always force Mutt to go through the local IMAP server? Many thanks in advance, -d

Re: Dovecot stops responding when I update SSL certificate
by HotSlots Webmaster 10 Mar '16

10 Mar '16

Time to put an end to this saga... I had an issue that Dovecot refused to serve an updated SSL certificate - one that Postfix had no issue with. Though I quadruple-checked that the cert file and private key file were correct, in the end I simply directed both cert and key files to the file I was using for Postfix (which had both the cert and private key). That worked. Darned if I know what it didn't like about the other files, but I'm back in business with the new cert. Thanks for the responsiveness from Aki. Steve L

Replication not working
by Simon Pierre Desrosiers 10 Mar '16

10 Mar '16

Hello, I am trying to setup replication between two Mac OS X El Capitan Server. I have added the field as I could understand from the replication page of dovecot and from a few poste in the mailing list. The mac uses the system user _dovecot as main system account. I have setup ssh keys between the two systems for the two _dovecot servers. SSh works fine from the terminal. But yet, I get these messages in the log file : Mar 09 20:18:44 auth: Error: od[getpwnam_ext](submit): No record for user Mar 09 20:18:44 doveadm: Error: Host key verification failed. Mar 09 20:18:44 dsync-local(submit): Error: read(_dovecot(a)laposte.mycompagny.com) failed: EOF Mar 09 20:18:44 dsync-local(submit): Error: Remote command returned error 255 Mar 09 20:23:44 auth: Error: od[getpwnam_ext](submit): No record for user Mar 09 20:23:44 doveadm: Error: Host key verification failed.

I have a few things about which I am not sure. We configure port 12345, but nothing listen on that port. The doveadm_password, what is it exactly ? Should I use a distinct account than _dovecot for synchronisation (all the fields that need to be added for replication) ? Here is my configuration, any help would be appreciated : # 2.2.5: /Library/Server/Mail/Config/dovecot/dovecot.conf # OS: Darwin 15.3.0 x86_64 hfs auth_mechanisms = cram-md5 digest-md5 gssapi

Released Pigeonhole v0.4.13.rc1 for Dovecot v2.2.22.rc1.
by Stephan Bosch 09 Mar '16

09 Mar '16

Hello Dovecot users, Pigeonhole v0.4.12 still compiles against Dovecot v2.2.22.rc1, but only with warnings. That is the primary reason for this new release. However, there are also a few significant changes as listed below. When no significant problems are reported, a definitive release will follow closely after Dovecot v2.2.22 is released. Changelog v0.4.13: * redirect action: Added the list-id header to the duplicate ID for mail loop prevention. This means that the message sent directly to the user and the message coming through the mailing list itself are treated as different messages by the loop detection of the redirect command, even though their Message-ID may be identical. * Changed the Sieve number type to uint64_t, which means that Sieve numbers can now technically range up to 2^64. Some other Sieve implementation allowed this, making this change necessary for successful migration. + Implemented the sieve_implicit_extensions setting. The extensions listed in this setting do not need to be enabled explicitly using the Sieve "require" command. This behavior directkly violates the standard, but can be necessary for compatibility with some existing implementations of Sieve. Do not use this setting unless you really need to! - redirect action: Made mail loop detection more robust by forcibly adding a Message-ID header if it is missing. - Prevent logging a useless "script not found" error message for LDAP scripts for which the entry exists but no attribute containing a script. This is not necessarily an error. - extprograms plugin: Changed the communication channel between parent and child process for a directly forked program from a socketpair to a double pipe. Linux does not support /dev/stdin, /dev/stdout and friends for sockets. For some shell program authors this may be confusing, so that is why it is changed. When using the script service, these device nodes are still not usable though. The release is available as follows: http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.13… http://pigeonhole.dovecot.org/releases/2.2/rc/dovecot-2.2-pigeonhole-0.4.13… Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this release candidate and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

dovecot: imap-login: Panic: Trying to allocate 0 bytes
by Ron Garret 08 Mar '16

My ISP had a hard drive crash. After the dust settled, my dovecot installation started failing with the following error every time a client tries to connect: dovecot: imap-login: Panic: Trying to allocate 0 bytes My installation has otherwise been stable and rock-solid for years. Both I and the techs at my ISP are stumped. Any advice on how to debug this would be greatly appreciated.

In fact, I’ve checked everything that I know how to check, and everything seems to be OK. And yet it is not working. Many thanks, rg

[PATCH] imapc: Accept strings in FLAGS responses
by Richard Laager 08 Mar '16

08 Mar '16

While non-standard, the IMAP server we are replacing returns non-system flags as strings instead of atoms. Prior to this change, imapc would abort processing on the first message with a string flag. --- src/lib-storage/index/imapc/imapc-mailbox.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/lib-storage/index/imapc/imapc-mailbox.c b/src/lib-storage/index/imapc/imapc-mailbox.c index c3e12d1..91333dc 100644 --- a/src/lib-storage/index/imapc/imapc-mailbox.c +++ b/src/lib-storage/index/imapc/imapc-mailbox.c @@ -310,7 +310,8 @@ static void imapc_untagged_fetch(const struct imapc_untagged_reply *reply, t_array_init(&keywords, 8); seen_flags = TRUE; for (j = 0; flags_list[j].type != IMAP_ARG_EOL; j++) { - if (!imap_arg_get_atom(&flags_list[j], &atom)) + if (!imap_arg_get_atom(&flags_list[j], &atom) && + !imap_arg_get_string(&flags_list[j], &atom)) return; if (atom[0] == '\\') flags |= imap_parse_system_flag(atom); -- 2.1.4
