[Dovecot] compile error with patched dovecot-1.2.rc4
by Carlos Xavier 21 May '09

21 May '09

Hi, I just downloaded the dovecot-1.2.rc4.tar.gz to do some tests. I coud compile it and generate the package with no trouble on my Slackware 12.2.0 Then as I wanted to try the patchs available at http://hg.dovecot.org/dovecot-1.2/# I downloaded them and applied at once. When I tried to compile once again I got this error: cmd-thread.o: In function `cmd_thread': cmd-thread.c:(.text+0x219): undefined reference to `mail_thread_type_parse' ../../src/lib-storage/libstorage.a(mail-search-build.o): In function `search_arg_build': mail-search-build.c:(.text+0x10b9): undefined reference to `mail_thread_type_parse' collect2: ld returned 1 exit status make[3]: *** [imap] Error 1 make[3]: Leaving directory `/usr/local/src/dovecot-1.2.rc4/src/imap' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/local/src/dovecot-1.2.rc4/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/src/dovecot-1.2.rc4' make: *** [all] Error 2 I removed the patched folder and untarred it again, but at this time I decided to apply one patch at time just to see witch one gave me the trouble. When the first set of patch ( http://hg.dovecot.org/dovecot-1.2/rev/d42a8623a008 ) was applied I got the same error. Just to confirm it was this set of patch, I applied all the other set of patchs leaving that one not applied and the compilation went out with no trouble. As im not a expert so I am sending this report to the list in order to get it fixed. Best Regards, Carlos Xavier.

[Dovecot] Problem with pam/krb5 auth on AIX 5.3
by Jonathan Siegle 20 May '09

20 May '09

I'm using pam to authenticate users against my krb5 realm. Here is the problem scenario: User test2 attempts to login and their password is not expired so dovecot says: 0 login test2 myfavoritepassword 0 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH] Logged in 1 logout * BYE Logging out 1 OK Logout completed. User test1 attempts to login, but their password is expired. So dovecot says: 0 login test1 myfavoritepassword 0 NO d expired User test2 attempts to login and their password is not expired. But dovecot still says: 0 login test2 myfavoritepassword 0 NO d expired If I kill the pid with name "dovecot-auth -w", user test2 can login just fine unless I login with the user test1 before trying user test2. So it seems like something is getting cached. I'm running imap-login out of inetd, in case that matters. In my dovecot.conf, I don't have any caching/authentication variables activated. I don't see anything obvious to type in passdb pam{ } to type. For debug, I've enable pam for telnet and tested that without error. Also, the logs show that test2 This is dovecot revision 9062:694714d59cd9 . Looking at the logs, I see user test2 authenticate correctly in all instances. thanks, Jonathan

[Dovecot] %d does not expand to domain
by Giuliano Gavazzi 20 May '09

20 May '09

Hello, dovecot-1.1.7 on FreeBSD 7.1. Usernames have dot in them (like uname.example for a user in example.com) in dovecot.conf I have: mail_location: maildir:/userhomes/maildirs/%d/%n/Maildir and for authentication: username_format: %Ln In the client, tried with CONE and Mail.app, I put the username as: uname.example(a)example.com So, the authentication works fine, as it extracts the uname.example from the uname.example(a)example.com supplied. The mail_location does not: Apr 27 17:21:26 drum dovecot: imap-login: Login: user=<uname.example>, method=PLAIN, rip=88.149.183.86, lip=88.149.202.106, TLS Apr 27 17:21:26 drum dovecot: IMAP(name.example): Effective uid=1301, gid=1301, userhomes=/userhomes/example.com/uname Apr 27 17:21:26 drum dovecot: IMAP(uname.example): Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes, subscriptions=yes Apr 27 17:21:26 drum dovecot: IMAP(uname.example): maildir: data=/ userhomes/maildirs//uname.example/Maildir Apr 27 17:21:26 drum dovecot: IMAP(uname.example): maildir++: root=/ userhomes/maildirs//uname.example/Maildir, index=, control=, inbox=/ userhomes/maildirs//uname.example/Maildir it looks like the %d expands to the empty string. Could this be due to the "." in the username? Thanks Giuliano

[Dovecot] maildir filename with eg. ,S=1000, omitted
by Joseph LP 20 May '09

20 May '09

Hello. I encountered the wiki entry on maildirs not long ago. In it, it is suggested that the use of ,S= and ,W= may improve performance as dovecot does not need to calculate size itself. While my maildir filenames have ,W=, they lack ,S=. I've grepped dovecot.conf, but I can find no option to address this. Regards, Joseph

[Dovecot] Dovecot is emptying Maildir folders
by Alexander Johannes 20 May '09

20 May '09

Hello, i have a annoying problem with dovecot after updating to 1.1.14. Dovecot seems to empty all cur/ and new/ Folders in the Maildir of a particular user several times a day (3 times so far). It leaves only unread messages in their place. All Index-Files are getting updated and reflect the "empty"-State of the Mailbox. A quick look over the logfiles reveals nothing which seems to be relevant to this malfunction. The error_log is empty for the relevant timeframe. There is no Expire/Expunge-Plugin running. Fortunately i have a hourly backup-snapshot to restore the Mailboxes, but this is obviously no solution. How can i debug this problem? Any advice is welcome. System: FreeBSD 7.1-RELEASE, dovecot-1.1.14, dovecot-managesieve-0.10.6, dovecot-sieve-1.1.6 (all installed via the ports-tree), exim-4.69_3 Clients: Thunderbird, Mail.app both IMAP only Regards, Alex
