[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.)

Hi, Was trying to use the gssapi support and the authentication would consistently die for me.

[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

[Dovecot] Simulating UW Snarf...
by Todd Piket 10 Feb '06

10 Feb '06

I already wrote to Timo, but I thought some others on this list may have had a similar situation. So here goes: The scenario at Michigan Technological University stems from long standing traditions and policies that probably won't change. That said, two of the policies are 1.)we don't bounce mail and 2.)we guarantee delivery when we accept a piece of mail. The UW IMAP "snarf" capability was nice because it allowed us to introduce file system, per user quotas w/o worrying about the "INBOX" in an over quota situation. This is because the user could still read mail. The delivered mail would get "snarfed" from /var/mail/user when the user went back under quota. In our test cases with switching to Maildir with Dovecot, we deliver directly to the user's INBOX instead of /var/mail/user so what do we do when the user is over quota because we can't bounce the mail? After many lengthy discussions our thought was this. Could we symbolically link the user's "Maildir/new" to a non-quota file system such that the move from "new" to "cur" would fail if the user is over quota? What will Dovecot do in that failure situation? Do you have other suggestions? I would be more than willing to develop a patch that makes this an option in the config file. Probably similar to allowing the indexes and control files be on a non-quota file system. Again, it would only allow "Maildir/new" to be on a separate file system, not the whole "INBOX". I hope this conveys the idea well enough. Any thoughts or ideas the list provides would be greatly appreciated. -- Regards, ------------------------------------------------------------ | Todd Piket | Email: todd(a)mtu.edu | | Programmer/Analyst | Phone: (906) 487-1720 | | Distributed Computing Services | | | Michigan Technological University | | ------------------------------------------------------------

[Dovecot] In-memory Index file bug
by Tony Kay 10 Feb '06

10 Feb '06

Hi, I am getting intermittent error messages in the log when my mail client tries to create/open a folder named ".imhoprefs". Some accounts seem to able to do it, but I have at least one that gives the log error: Feb 7 09:29:54 acad-cl1 dovecot: imap(tkay): close() failed with index file (in-memory index): Bad file descriptor I traced through the code, and it seems to be coming from mail_index_close() (line 1527 of mail-index.c), which seems to be attempting to close a file descriptor for an index. The funny thing is that since I am using in-memory indexes, I believe that there shouldn't be any file descriptor to close, which would explain why the close is failing... Environment information: - Dovecot 1.0b2 - mbox - Environment setting: default_mail_env = mbox:%h:INBOX=%h/.mail:INDEX=MEMORY - Attempting to create/use a folder called mail/.imhoprefs At first, I though the folder itself might be corrupted, so I removed it. No dice. I've checked file permissions. No problems. I honestly can't explain why some users are able to use this folder without error, and others are not. -- Anthony Kay University Computing Center (541) 346-1719 GPG Fingerprint: B0DB D46A 60AF FAE7 A94A 5075 0CB4 4D88 9F4F 7F09 Programming today is a race between software engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots.

[Dovecot] RE: epoll error when running as proxy
by Bill Boebel 10 Feb '06

Also, for testing in the error message I patched src/lib/ioloop-epoll.c to show the "ret" and "errno" variables as well as the variable names, which is why there is a bit of extra data in this error message... imap-login: io_loop_handle_add: epoll_ctl(op=3, fd=10, ret=-1, errno=2): No such file or directory Bill On Thursday, February 9, 2006 16:32, Bill Boebel said: > I am running dovecot 1.0 beta3 as a front-end proxy, and getting the > following error when using epoll.
