[Dovecot] authenticate plain and utf-8 with special chars
by Matthias Lay 04 Aug '12

04 Aug '12

Hi, I experienced some problems with authenticate. seems like the mail clients like thunderbird send their base64 string in ISO- encoding, which doesnt work on my dovecot setup if there are some Umlauts I am not able to login as "ömer" for example If I authenticate from telnet with an base64 encoded utf-8 string like 'echo -en "\0ömer\0Start12" |base64' everything works fine -dovecot 2.1.7 -userdb is an openldap which queries an windows AD so results are in utf8, I think. any clues at which point to fix this are welcome ;)

[Dovecot] Overriding inbox= in userdb extra fields
by Bret Martin 03 Aug '12

03 Aug '12

Hello, I'm trying to set up an alternate user with a different inbox using passwd-file and userdb extra fields and the extra field settings don't seem to be taking effect. I've used auth_debug and mail_debug and I'm unclear how I can further troubleshoot this. Is it possible to have inbox=yes in one namespace globally and then override this for one user by setting inbox=no for that namespace and then inbox=yes for another? My doveconf -n is below. I would like to have inbox=yes for the inbox namespace, inbox=no for the virtual namespace, and then be able to invert these for selected users using userdb extra fields. My attempt at doing this so far looks like bam-ios:[REDACTED]:500:500::/home/bam::user=bam namespace/inbox/inbox=no namespace/virtual/inbox=yes Changing the user with user= seems to work fine, but the inbox= changes don't. Here is some relevant log data.

[Dovecot] v2.1.9 released
by Timo Sirainen 03 Aug '12

03 Aug '12

http://dovecot.org/releases/2.1/dovecot-2.1.9.tar.gz http://dovecot.org/releases/2.1/dovecot-2.1.9.tar.gz.sig I've again mostly finished reading and answering most of the mails in Dovecot mailing list. There are a couple annoyingly difficult / time consuming bugreport mails that I haven't replied to yet, but if anyone thinks I should have replied to something already feel free to resend the mail. For the new Redis/memcached dict stuff see http://master.wiki2.dovecot.org/AuthDatabase/Dict and http://master.wiki2.dovecot.org/Quota/Dict I'm thinking about removing the new quota_ignore_save_errors=yes setting in v2.2 and just forcing it enabled always. Thoughts? (I didn't want to change v2.1 behavior by doing this.) The most important changes since v2.1.8: * mail-log plugin: Log mailbox names with UTF-8 everywhere (instead of mUTF-7 in some places and UTF-8 in other places) * director: Changed director_username_hash setting's default from %u to %Lu (= lowercase usernames). This doesn't break any existing installations, but might fix some of them. + doveadm: Added "auth cache flush [<username>]" command. + Implemented dict passdb/userdb + Implemented Redis and memcached dict backends, which can be used as auth backends. Redis can also be used as dict-quota backend. + Added plugin { quota_ignore_save_errors=yes } setting to allow saving a mail when quota lookup fails with temporary failure. - Full text search indexing might have failed for some messages, always causing indexer-worker process to run out of memory. - fts-lucene: Fixed handling SEARCH HEADER FROM/TO/SUBJECT/CC/BCC when the header wasn't lowercased. - fts-squat: Fixed crash when searching a virtual mailbox. - pop3: Fixed assert crash when doing UIDL on empty mailbox on some setups. - auth: GSSAPI RFC compliancy and error handling fixes. - Various fixes related to handling shared namespaces

[Dovecot] Antispam only when LMTP delivers some specific messages
by Sandro Tosi 03 Aug '12

03 Aug '12

Hello, we're setting up a weird platform where every incoming email is passed from the MTA directly to a tool that then uses dovecot LMTP to deliver the message into the user mailbox. We are legally *not* allowed to run antispam on all the incoming messages, but only on some of them, as they are recognized by the aforementioned tool; but given that tool directly uses LMTP to delivers the mail we need to find a way to parse the messages passing thru LMTP and run spamassassin only on those matching some regex on subject and mail body. Is is possible to do that with some dovecot LMTP feature? i've read a lot of documentation about how to possibly implement it and it *seems* there would be a way using pigeonhole sieve and extprograms - what do you think? The idea I have in mind is something like: 1. identify the mails we want to scan with spamassassin (using regex or whatever else to precisely pin-point them) 2. run SA on those 3. in case it's spam, rewrite the subject (or similar) Do you think it's something doable with dovecot?

What whould be the best way to do this, maybe in plugins/quota/quota.c:quota_root_add_rules() ? Regards, Michal Grzedzicki

hello I see this message in the dovecot error log every time a user connect to IMAP service. imap(xxxxxxxx): Error: opendir(/user/xxxxxxxx/.imap) failed: No such file or directory In the server's config I've this mail_location = mbox:%h/:INBOX=/var/mail/%u:INDEX=/var/spool/dovecot/index/%u As we can see INDEX files are not living in user's home directories but in /var/spool/dovecot/index/%u so why this error message ? BTW : users access normally to their IMAP folders , I'm just curious about this message which is not marked as warning but error Thank you
