[Dovecot] drac.c
by Takehiko Abe 13 Feb '06

13 Feb '06

Hello, I am using dovecot [1.0 beta3] as a pop server with drac. It is working nicely, but I am getting the following message in a log: dovecot: pop3(keke): file ioloop.c: line 154 (timeout_remove): \ assertion failed: (*timeout != NULL) dovecot: child 15752 (pop3) killed with signal 6 Adding '&' to 'to_drac' in drac_deinit of drac.c stops the message: void drac_deinit(void) { if (to_drac != NULL) timeout_remove(&to_drac); /* was to_drac */ } But I am not sure if the mod is correct. Thanks, T.

[Dovecot] Maximum Folder Size/Number of Messages
by Ropetin 13 Feb '06

13 Feb '06

I hope I'm asking this question in the right place, I don't want to offend. I've recently put together a proof of concept Dovecot IMAP server, and I'm very happy with its performance up to this point. I'm looking into using it to replace our existing POP3 server, allowing users to store email on the server rather than on their local machine, hopefully avoiding loss of data. The big question I have is, is there a realistic maximum realistic folder size, either in reference to number of messages or total file size with Dovecot? I'm using Maildir and running it on Debian Linux x86. Right now the filesystem is Ext3, although once the system goes live I'd be looking at something a little more fault tolerant and able to handle the large amount of data. Any recommendations you may have on Filesystem choice are appreciated too! Thanks, Ropetin.

[Dovecot] LDA delivery problem
by Martin Stephan 12 Feb '06

12 Feb '06

Hi I compiled and configured dovecot-lda as explained in the Wiki (current CVS version). Now I get the following error message: Action: failed Status: 5.0.0 Diagnostic-Code: X-Postfix; Command died with status 80: "/usr/local/libexec/dovecot/deliver". Command output: deliver: Fatal: Can't open log file /var/log/dovecot.log: Permission denied Now, do I have to set this socket listen { master { path = /var/run/dovecot-auth-master mode = 0666 user = vmail # User running Dovecot LDA group = vmail # alternatively mode 0660 + LDA user in this group } } to something else? Or chown the log file? I use Postfix and Dovecot on Ubuntu Breezy. Thanks Martin

[Dovecot] LDAP mailLocation weirdness
by Udo Rader 12 Feb '06

12 Feb '06

Hi, I've reported this some month ago before (without response), but still I have no clue what is going wrong. Our installation is LDAP based (for virtual hosting) and up to I think alpha2 or 3 everything was working as expected. The trouble I have is that dovecot does not correctly use the information it gets about mailLocation. This is what is stored in the MailMessageStore attribute for a user "f.someone": mbox:/virtual/oeush.at/var/mail/f.someone:INBOX=/virtual/oeush.at/var/mail/f.someone now despite of this setting, this user is unable to fetch any mail, because dovecot partially ignores this setting: ---------CUT--------- dovecot: Feb 04 12:20:42 Info: pop3(f.someone.oeush.at): Effective uid=200, gid=4000 dovecot: Feb 04 12:20:42 Info: pop3(f.someone.oeush.at): mbox: data=/virtual/oeush.at/home/f.someone/mail/:INBOX=/var/mail/f.someone.oeush.at dovecot: Feb 04 12:20:42 Info: pop3(f.someone.oeush.at): mbox: root=/virtual/oeush.at/home/f.someone/mail, index=/virtual/oeush.at/home/f.someone/mail, inbox=/var/mail/f.someone.oeush.at ---------CUT--------- As you can see, dovecot uses /virtual/oeush.at/... both for data and index but not for inbox, where it uses /var/mail/... My LDAP configuration for the mailLocation settings looks like this: ---------CUT--------- # User attributes in order: # Virtual user name (user@domain) # Home directory # MAIL environment # System user name (for getting user's groups from /etc/group) # - For virtual users you don't want to use this, so this defaults to none. # System UID # System GID user_attrs = uid,homeDirectory,MailMessageStore,,uidNumber,gidNumber ---------CUT--------- So where am I wrong?

[Dovecot] Compiling Dovecot with gssapi
by Luca Bertoncello 12 Feb '06

12 Feb '06

Hi, all! I'm new to Dovecot and I try to compile it to allow GSSAPI authentication. Unfortunately, configure says me always: Install prefix ...................... : /usr/local File offsets ........................ : 64bit I/O loop method ..................... : poll File change notification method ..... : dnotify Building with SSL support ........... : yes (OpenSSL) Building with IPv6 support .......... : yes Building with pop3 server ........... : yes Building with GSSAPI support ........ : no Building with user database modules . : static prefetch passwd passwd-file checkpassword mysql (modules) Building with password lookup modules : passwd passwd-file shadow pam checkpassword mysql (modules) And, of course, I can't use this authentication method... I searched in google and Dovecot docs, but I didn't found anything... Can someone help me? The system is a Linux RedHat 9 Thanks a lot! -- _______________________________ Luca Bertoncello -Programmierung / Mailserver- IMS Internet-Media-Service GmbH Bärensteiner Straße 7 01277 Dresden Fon: +49 351 2112034 Fax: +49 351 2112020 email: bertoncello(a)internet24.de

[Dovecot] Dovecot pop3s problem : can't see email

Hi. I am trying to setup dovecot running a pop3 service for external clients (and intend in future to setup an imap interface on localhost only for squirrelmail.)

[Dovecot] Bug in gssapi support

Hi, Was trying to use the gssapi support and the authentication would consistently die for me. The following patch fixes: --- src/auth/mech-gssapi.c.orig 2006-01-10 15:46:10.000000000 +1300 +++ src/auth/mech-gssapi.c @@ -138,7 +138,7 @@ static OM_uint32 obtain_service_credenti return major_status; } - gss_release_name(&minor_status, gss_principal); + gss_release_name(&minor_status, &gss_principal); return major_status; } as gss_release_name takes a pointer to a gss_name_t as second arg. cheers mark

[Dovecot] Outlook anonymous IMAP login
by Vincent Jaussaud 10 Feb '06

10 Feb '06

Hello guys, I'm trying to setup anonymous IMAP login on a bunch of Outlook clients, but it doesn't seems to work. I'm using dovecot-0.99.14-r1, on a Gentoo Linux OS. Using command line anonymous login, it's working just fine: youri / # telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. . CAPABILITY * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED NAMESPACE STARTTLS AUTH=PLAIN AUTH=ANONYMOUS . OK Capability completed. . AUTHENTICATE ANONYMOUS + . OK Logged in. But with Outlook it's not working at all. I tried using no password, or just some random stream, it makes no difference. The error I got in dovecot's logs are: Feb 07 12:31:16 Info: PAM: pam_authenticate(anonymous) failed: Authentication failure Feb 07 12:31:19 Info: PAM: pam_authenticate(anonymous) failed: Authentication failure Feb 07 12:31:28 Info: PAM: pam_authenticate(anonymous) failed: Authentication failure My assumption is that Outlook doesn't provide anonymous IMAP support. Could someone confirm this ? Do you know if any workaround/anonymous plugin exist ? Thanks ! --- Everything takes longer, costs more, and is less useful. -- Erwin Tomash
