[Dovecot] gssapi, kerberos and webmail
by Denis Cardon 14 Sep '07

14 Sep '07

Hi every one, first thanks for the great job, I switched successfully from courier imap a few months ago and both the migration and maintenance went smoothly from then on. The reason I switched was gssapi support (and the easier debug) and now I have thunderbird on Linux connecting in an SSO fashion through kerberos/GSSAPI (works great). Users should be able to access their mail throught a webmail too (eg. eGroupware). I have already checked for kerberos authentication on Apache, however there seems to be no way to have ticket forwarding throught PHP. AFIAK there is thus no way to use kerberos for php-imap --> dovecot authentication. The only information available seems to be the username. So here is my question : how do people on this mailing list handle kerberos authentication with webmail? Do you use other kind of authentication on privileged port (ie with access only from apache) and just do a login/nopassword authentication (like an uid base authentication through ldapi:/// on an ldap directory for example) ? Here is what we have with thunderbird : Thunderbird -------kerberos-------> dovecot on standard port Here is what I would guess for webmail auth : Firefox ------kerberos----> Apache ----gssapi-auth-just-using-login----> dovecot on privileges port Cheers, Denis -- Denis Cardon Tranquil IT Systems 44 bvd des pas enchantés 44230 Saint Sébastien sur Loire tel : +33 (0) 2.40.97.62.67 http://www.tranquil-it-systems.fr

[Dovecot] Dovecot / OS X 10.4 Mail.app and "Too Many Opened files" error message ?
by Xavier Beaudouin 14 Sep '07

14 Sep '07

Hello, I am trying to move from Courier-imap to dovecot.... Even if the processes to move logical (eg name spaces etc...) went very and without any problem, I've some etrange behavior when Imap client is Mac OS X Mail.app. I've got a big mailbox that have about 3 / 4G of mail in several folder (lots !!!)... After a long time, the OS X client say error : "Too Many opened files". I have check on the servers (a FreeBSD farm of 3 servers using freebsd ports of dovecot)... And nothing special... A question : why do I have never this kind of message on courier imap and why do I get this on dovecot... ? Configuration file on demand... if needed... THanks, /Xavier

[Dovecot] pipe() error but not linked to kqueue
by Patrick Milvich 14 Sep '07

14 Sep '07

I have dovecot 1.0.5 installed on an OpenBSD 4.1 box and an OS X Server 10.4.10 box. Sure you've all heard it before, because of the pipe error, no more login processes can be launched, and I have to restart the server. dovecot: Sep 13 05:50:00 Error: pipe() failed: Too many open files I first thought this was the issue with kqueue, but I've since recompiled making sure to use poll. This also happened with 1.0.3 and 1.0.2. It also happens very specifically after a dictionary attack that lasts usually about an hour, unless I can catch it earlier. (Around 18,000 login attempts) ex: dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<aaron>, method=PLAIN, rip=62.161.41.32, lip=<local ip> dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<adm>, method=PLAIN, rip=62.161.41.32, lip=<local ip> dovecot: Sep 13 05:49:58 Info: pop3-login: Aborted login: user=<account>, method=PLAIN, rip=62.161.41.32, lip=<local ip> But after the attack has subsided for a period of time, I still have the number of file descriptors maxed out for the dovecot process. I've increased the number available to have a higher roof, but that doesn't fix the problem. Wondering if anyone else has seen this issue, and also in a generic problem. How are others dealing the the problem of being attacked in this method? Is there a max number of login tries for a given ip address within a period of time that I'm missing? :) Thanks, Patrick

[Dovecot] dirsize quota assertion problem
by Alan Ferrency 14 Sep '07

14 Sep '07

Our current virtual mailbox configuration is not compatible with one of the assertions in the dovecot quota plugin's assertions in quota-dirsize.c. I believe the assertion is incorrect, but I would also be happy if I could get the same result with a better configuration setting. Here is a sample passdb entry which causes the quota assertion to fail: test(a)example.com:<snip>:3007:1000::/usr/boxes/username/example.com::userdb_mail=mbox:~/test^/.imap:INBOX=~/test userdb_uid=3007 userdb_gid=1000 userdb_home=/usr/boxes/username/example.com userdb_quota=dirsize:storage=100 The imap folder is "~/test^/.imap" and the INBOX is "~/test". As you can see, these are in different locations, but the INBOX string happens to be a substring of the imap folder directory. An example of the failed assertion error: Aug 31 16:44:13 www2 dovecot: IMAP(test(a)example.com): file quota-dirsize.c: line 180 (quota_count_path_add): assertion failed: (!is_file) This particular error log line was generated by dovecot 1.0.3, but the code in quota-dirsize.c is the same in dovecot 1.1 alpha3's version of quota-dirsize.c: 131 if (strncmp(count_path[i].path, path, strlen(path)) == 0) { 132 /* the new path contains the existing path */ 133 i_assert(!is_file); 134 count_path += i; 135 break; 136 } First, quota_count_path_add() is called for directory "~/test^/.imap" and it succeeds. When it is subsequently called for file "~/test": - the strncmp matches because "~/test" is a substring of "~/test^/.imap" - the assertion fails because "~/test" is a file and not a directory It seems to me that instead of asserting !is_file, it would be better to simply skip the conditional in that case, since a path variable that is a file should never be tested to see whether it contains an existing path. if (!is_file && strncmp(count_path[i].path, path, strlen(path)) == 0) { /* the new path contains the existing path */ count_path += i; break; } But this also has a bug: if path is a directory which substring matches count_path[i].path, but the same path with a directory separator appended to it does not substring match count_path[i].path, then it is a different path and does not contain the existing path. For example, if count_path[i] is the directory /usr/home/test/mailbox_folders, and path is the directory /usr/home/test/mailbox, then /usr/home/test/mailbox does not contain/usr/home/test/mailbox_folders, and this condition should fail. If some other code were to enforce that /usr/home/test/mailbox be terminated with a directory separator, then this is not a problem and my patch should work. I hope this makes sense.

[Dovecot] Dovecot + virtual users
by bichumo 13 Sep '07

13 Sep '07

Hi, I'm running FreeBSD, Dovecot, Postfix (virtual users), MySQL, Squirrelmail. I have installed squirrelmail-quota_usage-plugin, but I cannot make it work. It mentions "If you have an IMAP server with QUOTA Extension capability...". In dovecot.conf I have enabled "mail_plugins = quota" near protocol pop3 and protocol lda, near protocol imap I have "mail_plugins = quota imap_quota". Near " plugin { ..." I have "quota = maildir:storage=204800". I think that the problem of why I don't see quota in Squirrelmail is in file dovecot-sql near user_query. I have my users mailboxes in such format: /usr/local/virtual/domain.tld/username and my user_query looks like this: user_query = SELECT maildir, 125 AS uid, 125 AS gid, concat('maildir:storage=', quota) AS quota FROM mailbox WHERE username = '%u' AND active = '1', I think that in my user_query I'm missing something. I do not get any errors in the dovecot and dovecot-debug logs, everything works fine, but I still can't see quota.

[Dovecot] Datehandling bug?
by Ed W 12 Sep '07

12 Sep '07

Hi, I am testing dovecot 1.0.3 alongside my existing courier installation and a number of my emails are heading to the top of the inbox even though they are rather old. Closer inspection shows that my mailclient (Thunderbird on Win32) is showing me some screwey dates for a number of messages. One example is an email which says: Date: 2007-08-21 11:42:43 But in TB I see the date shown as only: 03:27 ie just a time and no date OK, the date above is clearly not an RFC date, but any idea why this is showing up only under Dovecot? Is it a dovecot date handling issue? Cheers Ed W

[Dovecot] postfix + dspam + dovecot problem
by Lars Stavholm 11 Sep '07

11 Sep '07

Hi All, I'm new to dovecot (coming from cyrus) and have a bit of a problem setting up postfix + dspam + dovecot. 1. postfix + dovecot: works like a charm. Using "mailbox_command = /usr/lib/dovecot/deliver" in postfix main.cf 2. adding dspam to the equation: unable to deliver: net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Using "mailbox_transport = lmtp:unix:/var/tmp/dspam.sock" in postfix main.cf (instead of the above mailbox_command), and the corresponding setting in master.cf. In /etc/dspam.conf I'm using... TrustedDeliveryAgent "/usr/lib/dovecot/deliver" And here's the full error message: Sep 11 02:10:38 nwinnie postfix/pickup[18313]: 090F1C042: uid=0 from=<root> Sep 11 02:10:38 nwinnie postfix/cleanup[7010]: 090F1C042: message-id=<20070911001038.090F1C042(a)nwinnie.telcotec.se> Sep 11 02:10:38 nwinnie postfix/qmgr[18318]: 090F1C042: from=<root(a)nwinnie.telcotec.se>, size=431, nrcpt=1 (queue active) Sep 11 02:10:38 nwinnie deliver(stava(a)nwinnie.telcotec.se): net_connect(/usr/var/run/dovecot/auth-master) failed: No such file or directory Sep 11 02:10:38 nwinnie dspam[10379]: Delivery agent returned exit code 75: /usr/lib/dovecot/deliver -d stava(a)nwinnie.telcotec.se Sep 11 02:10:38 nwinnie postfix/lmtp[7018]: 090F1C042: to=<stava(a)nwinnie.telcotec.se>, orig_to=<stava>, relay=nwinnie.telcotec.se[/var/tmp/dspam.sock], delay=0.35, delays=0.32/0.01/0.01/0.01, dsn=4.3.0, status=deferred (host nwinnie.telcotec.se[/var/tmp/dspam.sock] said: 421 4.3.0 <stava(a)nwinnie.telcotec.se> Delivered (in reply to end of DATA command)) So, postfix hands the message to dspam, dspam does its thing, dspam tries to deliver and fails. What throws me is that the delivery works as expected in case 1) but not in case 2), despite the fact I'm using the same delivery agent, i.e. /usr/lib/dovecot/deliver. Why would dovecot go for some other authentication method in case 2)? BTW, we're using PAM on top of LDAP. Any ideas appreciated. Cheers /Lars

[Dovecot] Write-only mailboxes
by Steffen Kaiser 11 Sep '07

11 Sep '07

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, I've setup a mailbox for reporting SPAM by simply symlinking it into the Maildir of selected users. In order to preserve anonymity of the users I setup the mailbox as follows: drwxr-xr-t 5 root fb 4096 2007-09-05 16:18 ./ drwxr-xr-x 7 root root 4096 2007-09-05 16:16 ../ drwx-wx-wt 2 spamd fb 12288 2007-09-10 16:17 cur/ hence, with read permission for the spam bot only. When Thunderbird copies mails from the same mail account into the folder, it seems like it tries to select the mail box afterwards, then a "Internal error occured. Refer to server log for more information." because of permission denied. When one copies mail from yet another account into the SPAM box, no such message appears. I guess, Thunderbird does not try the refresh the message count. Well, is there a possiblity to setup a Write-Only mailbox, with Dovecot v1.0.3 with the ACL plugin? Is there a working setup for write-only mailboxes with the ACL plugin?

Thanks. That is a good point. Sounds like "login_processes_count=1" is the thing to do.

[Dovecot] multiple emails
by dhottinger＠harrisonburg.k12.va.us 10 Sep '07

10 Sep '07

I have a weird issue where several users are recieving the same email's multiple times. Each email has a different que id, but are exactly the same otherwise. I thought at first this was a new spam, but I have local users doing the same thing. Im not sure where to start looking for the root of this problem. Seems to be pretty widespread across multiple platforms. I currently utilize openldap for user database, sendmail, Dovecot-Imap, and horde webmail. Im not sure where to start digging for this problem, Ive scanned through all my log files and havent found anything. Any guidance would be great. thanks, ddh -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools
