[Dovecot] mail to admin when quota exceeded
by Karolis Žvaigždinas 16 Jan '11

16 Jan '11

We're using Dovecot v1.2.15 LDA/IMAP/POP3+MySQL with quota plugin, quota_rule per-user size, quota_exceed_message and quota_warning on storage=90%%.with script. Everything is working as expected. But I've been asked to configure it the way, that when a user gets message, which would make his maildir over quota limit, notification go not only to sender, but also to postmaster(a)domain.com. Browsed wiki, mailinglist archive - couldn't find anything on that. Is there a way to implement such feature? And what about possibility to send a message to user, notifying him about rejected email "from: xxx(a)yyy.com" with "subj: blah blah" due to full mailbox? Such messages are small and would not take too much space. Thus the user would know what he misses, urging him to clean his mailbox. Thank you in advance. -- Karolis

[Dovecot] [PATCH] auth: Fixed mech_winbind_ntlm by using mech_winbind_auth_initial()
by Christian Wiese 16 Jan '11

16 Jan '11

Hi folks, attached is a trivial patch which is fixing Winbind/NTLM authentication in dovecot 2.0 series. The patch was made against 2.0.8 sources, but there should be no problem applying it onto HEAD, because 'src/auth/mech-winbind.c' wasn't touched for quite some time now ;) I tested the patch with a dovecot 2.0.8 running on linux, authenticating against a WindowsServer 2008R2 Enterprise using ntlm_auth/winbind (from current stable samba 3.5.6). I successfully tested NTLM authentication for IMAP and POP3 (with and without STARTTLS) using following MUAs for the test: - Thunderbird 3.1.7 (Linux X86-64) - Outlook Express 6.00 (Windows XP Pro Qemu-KVM) Cheers, Chris Patch Description: In changeset 9002 a new function named mech_winbind_auth_initial() was introduced, but only the mech_winbind_spnego module part was changed to finally use this function. The mech_winbind_ntlm module part was not properly adapted which leads to a non functioning NTLM authentication mechanism while using winbind, because it will never call the `ntlm_auth` helper. The simple fix is to replace mech_generic_auth_initial() with mech_winbind_auth_initial() as auth_initial "hook" when setting up the mech_winbind_ntlm module, like it is done in the mech_winbind_spnego module. References: - Changeset 9002: http://hg.dovecot.org/dovecot-2.0/diff/9d0037a997f4/src/auth/mech-winbind.c

[Dovecot] Seeing other people subscribed non-shared mailboxes
by Thomas Hummel 16 Jan '11

16 Jan '11

Hello Timo, With dovecot-2.0.8/Maildir, in a simple shared mailboxes setting I noticed the following : - user "doveimap" has 2 mailboxes : "Common" and "Private" - he shares only the "Common" mailbox to user "dovepop" doing : x setacl "Common" dovepop lrwstipekxacd x OK Setacl complete. - he subscribed to both x lsub "" * * LSUB () "." "Trash" * LSUB () "." "Common" * LSUB () "." "Private" x OK Lsub completed. I'm not realy sure if the fact that "dovepop" can see doveimap's subscribed "Private" mailbox in the "#Shared" namespace is legitimate or not : x login dovepop xxxxx x OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS ACL RIGHTS=texk] Logged in x list "" * * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "INBOX" * LIST (\Noselect \HasChildren) "." "#shared.doveimap" * LIST (\HasNoChildren) "." "#shared.doveimap.Common" x OK List completed. x lsub "" * * LSUB () "."

"#shared.doveimap.Private" x OK Lsub completed. x logout Is this the way it's supposed to work ? My setup is : namespace { type = shared separator = "." prefix = "#shared.%%u." location = maildir:/courriel/boites/%%u:INDEX=/var/dovecot-2/indexes/%1u/%u/shared/%%u:CONTROL=/courriel/meta/%%u # Use the default namespace for saving subscriptions. # subscriptions = no # hidden = no # list = no list = children } # pwd /courriel/boites/doveimap # cat dovecot-acl-list 1294755382 Common # cat .Common/dovecot-acl user=dovepop akxeilprwts # cat .Private/dovecot-acl cat: .Private/dovecot-acl: No such file or directory Also, I'm not sure I correctly understand what "Use the default namespace for saving subscriptions." option is. Is it just the location of the subscription file for mailboxes subscribed in the shared namespace ? Where would it be if set to "yes" ? Thanks. -- Thomas Hummel | Institut Pasteur <hummel(a)pasteur.fr> | Pôle informatique - systèmes et réseau

[Dovecot] dovecot lda and quota plugin with mysql
