charset_to_utf8 assertion of remaining src_size
by Xin Li 22 May '15

22 May '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I have seen the following assertion fails on my own mail server (indexer-worker): Panic: file charset-iconv.c: line 132 (charset_to_utf8): assertion failed: (*src_size - pos <= CHARSET_MAX_PENDING_BUF_SIZE) However, when charset_to_utf8_try returns FALSE (e.g. iconv() got EINVAL or EILSEQ), the for loop in charset_to_utf8 may end earlier, and there may be additional pending characters, and the assertion doesn't seem always hold in the error case, perhaps we should assert that pos is non-zero in the error case?

"doveadm backup" doesn't work anymore after upgrading to 2.2.18
by Jesus Cea 21 May '15

21 May '15

Until today I could do this to backup my primary IMAP4 server: """ doveadm backup ssh csi doveadm dsync-server """ It doesn't work anymore after upgrading to Dovecot 2.2.18: """ jcea@ubuntu:~$ doveadm backup ssh csi doveadm dsync-server Enter passphrase for key '/home/jcea/.ssh/id_rsa': dsync-remote(root): Error: Mailbox INBOX: Failed to get attribute vendor/vendor.dovecot/pvt/server/sieve/default: Mailbox attributes not enabled dsync-local(jcea): Error: Remote command returned error 65: ssh csi doveadm dsync-server dsync-server """ The first error is regular business: I don't have SIEVE in the backup, since it is a backup. I have seen this error forever, no consequences. Now in 2.2.18 I get the second error and the backup is aborted. It doesn't work anymore. I don't find any reference to error 65 anywhere. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ jcea(a)jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz

Log mail access
by Philipp Brüll 20 May '15

20 May '15

Hello, is it somehow possible to log the access to a mail? The log entry should be written, if a user fetches a mail via imap or pop3. It would be convenient for debugging. I've checked the Logging-Wiki and the docs for the mail_log plugin, but they seem to log any event but "mail access". Best regards, Philipp

I'm digging on it now. Thanks. Samuel.

Re: Controlling shared folder rename?
by andy＠thecsillags.com 19 May '15

19 May '15

Eventually I figured out a solution that looks like it should work; postlogin scripting described here http://wiki2.dovecot.org/PostLoginScripting . Specifically, the sample at the bottom that adds a shared folder, obviously will need some work to make it work the way I want, but it should work. May 19 2015 3:18 PM, andy(a)thecsillags.com (mailto:andy@thecsillags.com) wrote: Dovecot version 2.2.16 I'm using shared folders and what I'd like to do is either have the folder that gets shared be able to be renamed by the user, or failing that, to be able to have an administrator define how the shared folder shows up to the account it's shared to. For example, right now, the INBOX owned by testuser(a)mydomain.com (mailto:testuser@mydomain.com) is shared to otheruser@mydomain as shows up as shared/testuser(a)mydomain.com (mailto:testuser@mydomain.com) because of the prefix directive in the shared namespace in 10-mail.conf. It would be nice if, either via a dict (like the way the acls work), or via normal IMAP folder commands, that I control how it shows up to otheruser@mydomain. So if I could do something like: prefix = proxy::sharedname or similar. Currently trying to rename from IMAP fails -- given the way my understanding of how things works is, I'm not surprised, but hey, it was worth a shot right? First, does the question make sense? Two, is there a way to do this? Thanks, :Drew

And I don't understand why dovecot doesn't use it. So I revert back my dirty user_query and I'm still searching why I can't send email to alias .... Thanks. Samuel.

Understanding the "doveadm replicator status" output
by Listas＠Adminlinux 19 May '15

19 May '15

Where can I get more detailed information about the output of the 'doveadm replicator status' ? man doveadm-replicator isn't enough. For example, Total number of known users = 29409, but the server has only 17667 users. This is confusing. Look: # doveadm user '*' |wc -l 17667 # doveadm replicator status Queued 'sync' requests 0 Queued 'high' requests 0 Queued 'low' requests 0 Queued 'failed' requests 0 Queued 'full resync' requests 12962 Waiting 'failed' requests 16447 Total number of known users 29409 What it means to "Queued full resync requests" ? thanks!

Wanting for any suggestion .... Samuel.

Can't achieve alias working with SQL
by Samuel 19 May '15

19 May '15

Hello, On a fresh install of Jessie, I achieve to make dovecot/postfix working with SQL, but I still can't send email to alias for wich one I get : "Unknown user" After debug enable in dovecot, I see that the user_query SQL , just query for the "users" table and not the "forward" table so the final alias user is not known. But when I check postfix for alias, it seems ok : root@cluster-dovecot:/etc/dovecot# postmap -q contact2(a)XXXXXXXX.com mysql:alias_maps contact(a)XXXXXXXXXX.com So what do I missed for alias working with dovecot ? Do I need a special conf in master.conf for sending alias AND final recipient or do I have to change the dovecot user_query for taking in acount the "forward" table in the SQL query ? .... or other thing I could miss ... Thanks a lot ... Samuel.
