[Dovecot] Dovecot 1.2.beta1 Backtrace POP3
by Steven King 21 Feb '09

21 Feb '09

I am testing out the new Dovecot 1.2.beta1 software. I am getting reports from people using POP3 that it randomly drops connections. Looking at the log file I see that the POP3 process they were connecting to panics and dumps a Raw bactrace. Below is a copy of the logs (IP addresses striped for security): dovecot: Feb 21 13:10:45 Info: auth(default): passwd-file(janna(a)jantics.com,x.x.x.x): lookup: user=janna(a)jantics.com file=/etc/postfix/passwd dovecot: Feb 21 13:10:45 Info: auth(default): master out: USER 3340 janna(a)jantics.com uid=1005 gid=102 home=/var/mail/vhosts/%d/%n quota=maildir quota_rule=*:storage=100M quota_rule2=Trash:storage=50M dovecot: Feb 21 13:10:45 Panic: POP3(janna(a)jantics.com): Trying to allocate 0 bytes dovecot: Feb 21 13:10:45 Error: POP3(janna(a)jantics.com): Raw backtrace: pop3 [0x80d18fc] -> pop3 [0x80d195a] -> pop3 [0x80d125b] -> pop3 [0x80db683] -> pop3(i_malloc+0x15) [0x80d5ee5] -> pop3(client_create+0x503) [0x805c573] -> pop3(main+0x3ce) [0x805e00e] -> /lib/libc.so.6(__libc_start_main+0xe0) [0xb7e39390] -> pop3 [0x805b7e1] dovecot: Feb 21 13:10:45 Error: child 26895 (pop3) killed with signal 6 dovecot: Feb 21 13:10:45 Info: pop3-login: Login: user=<janna(a)jantics.com>, method=PLAIN, rip=69.54.221.129, lip=x.x.x.x -- Steve King Network Engineer - Liquid Web, Inc.

[Dovecot] Maildir with INBOX and other folders at same level
by Seth Rhudy 21 Feb '09

21 Feb '09

Hello- I have set up Dovecot before and feel fairly comfortable with it but am having some issues with a new setup and have not been able to find a solution via Google or the list archives. I use offlineiimap to sync an IMAP account with an email provider. After the sync is complete, my ~/Maildir is set up with a folder called INBOX (with cur,new,tmp inside) and all my other folders set up at same level as INBOX (also with cur,new,tmp inside): ~/Maildir INBOX cur new tmp Otherfolder1 cur new tmp Otherfolder2 cur new tmp etc.. This email provider says that they use '/' as the IMAP folder separator so '.' can be used in folder names. Anyway, I am using Dovecot 1.0.15 on Debian Lenny and can't seem to get Dovecot to recognize this folder structure and display it in my MUA. In my dovecot.conf, I have: mail_location = maildir:~/Maildir When I fire up my MUA it connects fine but does not display anything -- the INBOX is empty and the other folders are not there. I have tried various configurations with the namespace private {} section but without success. What am I missing? Thank you in advance for your assistance.

[Dovecot] Sendmail + Deliver as an LDA probs
by ben 21 Feb '09

21 Feb '09

Hi, I'm having trouble setting up sendmail to be able to use dovecot deliver as an LDA... I don't want to be able to deliver mail locally, everything should go via deliver (virtual user setup)... And i'm confused about all the procmail/lda entry's in different sendmail config files... When using $# deliver -u testuser < testmail <-- he delivers my mail in the correct mailbox as stated in my dovecot passdb file homedir. So deliver is working fine ! ---- I used the dovecot.m4 from wiki.dovecot.org/LDA/sendmail sendmail.mc fragment (only lines affecting Local delivery) : DOMAIN(`blaat')dnl MODIFY_MAILER_FLAGS(`LOL', `-S')dnl FEATURE(`local_procmail')dnl define(`LOL_MAILER_PATH',`/usr/bin/procmail')dnl define(`PROCMAIL_MAILER_PATH',`/usr/bin/procmail')dnl dnl MAILER(`local')dnl MAILER(`smtp')dnl MAILER(`procmail')dnl MAILER(`dovecot')dnl dnl ------ blaat.m4 fragment : define(`LOCAL_MAILER_PATH',`/usr/bin/procmail') define(`PROCMAIL_MAILER_PATH',`/usr/bin/procmail') ------ more /usr/local/src/sendmail-x.x/cf/mailer/dovecot.m4 : ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/opt/dovecot/libexec/dovecot/deliver, F=DFMPhnu9, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, T=DNS/RFC822/X-Unix, A=deliver -d $u ------- virtusertable/virtusertable.db : test(a)testdomain.com blaatuser --------- aliases/aliases.db : blaatuser | /opt/dovecot/libexec/dovecot/deliver -d $u ---- sendmail.cw = empty ----- mailertable/mailertable.db : testdomain.com dovecot:dovecot ################# When I run #$ sendmail -bv test(a)testdomain.com sendmail gives : test(a)testdomain.com... deliverable: mailer local, user test (as a matter of fact the user test does exist on my machine, so what he does is stripping of the domainname and he delivers the mail in /var/spool/mqueue/test :-/ ) And I don't see anything in my deliver logfile of course... Help would be appreciated ! thx Ben

[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

[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.
