[Dovecot] location of temporary files in deliver
by Stuart Henderson 21 Feb '09

21 Feb '09

deliver has the following: -- -- -- /* After buffer grows larger than this, create a temporary file to /tmp where to read the mail. */ #define MAIL_MAX_MEMORY_BUFFER (1024*128) ... static struct istream *create_raw_stream(int fd, time_t *mtime_r) ... input = i_stream_create_seekable(input_list, MAIL_MAX_MEMORY_BUFFER, "/tmp/dovecot.deliver."); -- -- -- On most of my systems, /tmp is relatively small (a few hundred MB, and sometimes on ramdisk), and I like to use /var/tmp for larger temp space. I just had a problem where I exceeded the space available in /tmp while delivering a (multi recipient) message and had to modify the above line to use an alternative location, and recompile. Would it be appropriate to make this a configurable option instead? Thanks.

[Dovecot] How many namespaces for several groups of shared mailboxes ?
by Thomas Hummel 21 Feb '09

21 Feb '09

Hello Timo, let's say you want to implement several distinct groups of shared mailboxes via one (several) public namespace(s) with dovecot-1.1.x/Maildir. For instance, team1, team2 and team3 work on different projects (project1, project2, project3). Obviously, as many public namespaces (#team1, #team2, #team3) would do the trick, but then, any user (including users who don't belong to any above team) would 'see' useless non-selectionable folders #team*. So my idea would be to create only one public namespace (#Public) into which I'd store directories team1, team2, team3, into which I'd put the needed shared mailboxes. Something like /courriel/boites/public/team1/.shared-project1/ /team2/.shared-project2/ /team3/.shared-project3/ with something like namespace public { separator = / prefix = '#Public/' location = maildir:/courriel/boites/public inbox = no hidden = no list = yes subscriptions = yes } I guess if unix right and ACL are set up correctly, other people would only see non-selectionable '#Public'. The only problem is the subscription file : my understanding is that you have only one subscription file per namespace. Maybe unless you specify something like location = maildir:/courriel/boites/public:CONTROL=<some user dependent location> But wouldn't that induce another problem : such a CONTROL directive would put dovecot-uidlist and dovecot-keywords in the same user dependent location. As I want to share the \Seen flag, I have to . put a dovecot-shared file . not specify INDEX (or at least, not to some user dependent location) So I would end up with . uid lists in some user dependant location (as a side effect of having several subscriptions files) . but indexes shared as uid is listed in index : wouldn't that be a problem ? thanks -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

I just switched from the default postfix LDA to the dovecot LDA, deliver, and am looking into what new features I have. The wiki references the trash plugin with imap. Can I also enable trash with the lda? Rick Rick Steeves http://www.sinister.net "The journey is the destination"

[Dovecot] Quota not reporting with getquotaroot
by dovecot＠corwyn.net 21 Feb '09

21 Feb '09

I'm running squirrelmail on top of dovecot, and noticed that some of my users display the quota (using the squirrelmail plugin check_quota) and some don't. So I did some digging. For those that do not display the quota, their account also doesn't provide any data with: . getquotaroot inbox * QUOTAROOT "inbox" . OK Getquotaroot completed. When I check the account /Maildir folder it has info in maildirsize 0S 12744423 10 334 1 483685 1 and when I delete the maildirsize file it recreates. any ideas? thx.

[Dovecot] Different protocols with different auth-types
by Morton.Trust 21 Feb '09

21 Feb '09

Hello, I have installed dovecot with MySQL in which the users are stored. Now I want to separate IMAP-Users from POP3-Users. So I added two columns to the user table (imap / pop3) which indicates, whether the user has access to IMAP or not. In order to get dovecot recognizing this separation I put the auth-config into the two protocol-sections and wrote two different dovecot-sql.conf-files. In the dovecot-sql-pop3.conf the query searches for pop3=1 and in the dovecot-sql-imap.conf it searches for imap=1. Done that, I expected POP3-Only-Users getting an error while trying to connect to the IMAP-service. But dovecot first tries to authenticate for IMAP and then uses the POP3-auth as fallback. How can I do this separation? Thanks a lot, Morton -- View this message in context: http://www.nabble.com/Different-protocols-with-different-auth-types-tp22085… Sent from the Dovecot mailing list archive at Nabble.com.

Hi Actually I use quota. But I would like to use dict quota car with dict quota it is possible to view the used quota. But I do not understand the configuration off dict quota. if the quota is stored in mysql wich do I have to specify quota values in plugin section as chown in the dovecot web site? exemples: dict { quotadict = mysql:/etc/dovecot-dict-quota.conf } plugin { # v1.0: 10MB and 1000 messages quota limit quota = dict:storage=10240:messages=1000 proxy::quotadict # v1.1 + SQL: quota = dict:user::proxy::quotadict quota_rule = *:storage=10M:messages=1000 Thanks
