[Dovecot] Sieve vacation not working
by Phill Edwards 24 Feb '15

24 Feb '15

I've been trying all night to get vacation working in my .dovecot.sieve file. The way our email works is we have one account on dovecot which serves my mail and my wife's and we use procmail and sieve to put the emails in different folders depending on who it's for. I'm trying to set up a vacation reply on my wife's email address (aaaaaaaa@optus* below) so people can update to her new address. Here's my file with the email addresses masked: require ["fileinto", "vacation"]; if address :is "to" "xxxxxxxxxxxxxxx(a)ozemail.com.au" { fileinto "Phill_OzEmail_Folder"; stop; } elsif address :is "to" "yyyyyyyyyyyyyyyyy(a)optusnet.com.au" { fileinto "Phill_Optus_Folder"; stop; } elsif address :matches "to" "aaaaaaaa@optus*" { vacation "Please update my email address to bbbbbbbbb(a)exemail.com.au"; fileinto "Sarah_Optus_Folder"; stop; } else { keep; stop; } The problem I'm having is that no auto-replies are sent. I removed .dovecot.lda-dupes and that didn't help; so then I touched it and now it's a 0 byte file and that didn't help. There is no dovecot.sieve.err file and I can't see anything in /var/log/dovecot.log which gives any message about why this wouldn't work. The emails to aaaaaaa@optus* get filed into the right folder so I know the matching is working. I've also tried a reject recipe and that worked fine, so I know that it can send an email if it chooses to. So it's a complete black box mystery as to why it just won't send a reply. Regards, Phill

Permissions for shared mail don't work
by Damien Desfontaines 17 Feb '15

17 Feb '15

Hello, (Sorry if you already received this mail. I sent it without having subscribed to the list, but I never got any confirmation; so I assumed it has been filtered by the anti-spam or something.) I'm using dovecot v.2.1.7 on Debian Sid, and the output of dovecot -n is available here: http://paste.fulltxt.net/C-O I'm trying to make the mailbox of (system) user "spam" available to user "ted". I followed these instructions: http://wiki2.dovecot.org/SharedMailboxes/Permissions and it doesn't seem to work. To be more precise: - I manually (and recursively) changed the permissions of all files in ~spam/Mail to 660 (and 770 for the directories); - I manually (and recursively) changed the group owner of everything in ~spam/Mail to "mailperso", where "mailperso" is a group whose users are spam and ted; - I added « mail_access_groups=mailperso » into my dovecot config; - and I restarted dovecot. But still, when I send a new email to spam, it appears as being owned by group "spam" and having permissions set to 600, so I can't access it with user "ted". I also tried to set the setgid bit for ~spam/Mail, it didn't change anything, and when I recursively set the setgid for all subdirectories of ~spam/Mail, it gives new mails the correct group (mailperso) but not the correct permissions. Have I missed something, or is this a bug? Thanks in advance and best regards, Damien

Howto NTML
by Mark Foley 13 Feb '15

13 Feb '15

Has anyone gotten NTLM working with Dovecot and Outlook? I have a Samba4 domain controller / active directory running just fine on Linux Slackware64 14.1. PLAIN authenticiation works just fine if I create /etc/passwd accounts for the domain users. I've tried for over two weeks to get NTLM working from Outlook 2007 on a domain workstation without success. I end up with various permission errors and ultimately procmail won't deliver if I "adjust" mailbox folder permissions too liberally. Also it seems I have to log in each time in Outlook. If someone has made this work, I'd be very interesting in seeing the doveconf -n output, the permissions on the mailbox directories, the nsswitch.conf, and anything else you had to tweak to get this working. I'd really love to have AD authentication working on this setup! --Mark

Corruption of index files
by Oliver Welter 04 Feb '15

04 Feb '15

Hi All, after upgrading my mail server (dovecot 1.1.7 -> 2.2.13) I get tons of messages about corrupted index files in the syslog ("Error: Corrupted transaction log" and "Warning: fscking index file .. dovecot.index". I tried flock and even dotlock, but the problems persist. The system is a VPS with an overlay filesystem which did work flawlessly with the old dovecot install and is not reporting any errors in the host machine. From time to time I get warnings about an exceeded inotify limit for the dovecot user - might this be a problem? Anybody has an idea what might be the cause those problems and how to track them down.

LDAP: "unused" & "uid missing"
by Leander Schäfer 02 Feb '15

02 Feb '15

Does someone know what this means? It looks to me like it got the UID, yet it complains ... ? Also, why does it complain about attributes being unused, yet I use prefetch, so they will be used?! Log: [...] dovecot: auth: Debug: ldap(test(a)mydomain.tld,192.168.10.233,<Rl2CF+UNhgDAqArp>): result: mailStorageDirectory=/var/vmail mailUidNumber=2110 mailGidNumber=2110 mailQuotaStorage=10240 mailQuotaMessages=20; mailQuotaMessages,mailStorageDirectory,mailUidNumber,mailQuotaStorage,mailGidNumber unused dovecot: auth: Debug: ldap(test(a)mydomain.tld,192.168.10.233,<Rl2CF+UNhgDAqArp>): result: mailStorageDirectory=/var/vmail mailUidNumber=2110 mailGidNumber=2110 mailQuotaStorage=10240 mailQuotaMessages=20; uid missing [...] As mentioned, I use prefetch, so this is how my dovecot/dovecot-ldap.conf.ext is looking: [...] #user_attrs = mailStorageDirectory=home=%$/%u, mailStorageDirectory=mail=maildir:%$/%u/maildir, mailUidNumber=uid, mailGidNumber=gid, mailQuotaStorage=quota_rule=*:storage=%$, mailQuotaMessages=quota_rule2=*:messages=%$ pass_attrs = uid=user, userPassword=password, mailStorageDirectory=userdb_home=%$/%u, mailStorageDirectory=userdb_mail=maildir:%$/%u/maildir, mailUidNumber=userdb_uid, mailGidNumber=userdb_gid, mailQuotaStorage=userdb_quota_rule=*:storage=%$, mailQuotaMessages=userdb_quota_rule2=*:messages=%$ [...] Thanks

Sieve permissions issue following update
by David Gessel 02 Feb '15

02 Feb '15

I recently updated dovecot and my sieve filters stopped working. Checking the logs I see: Dec 9 00:09:59 mailhost dovecot: lda(gessel(a)domain.com): Error: sieve: binary save: failed to create temporary file: open(/usr/local/etc/dovecot/sieve/10-move-spam.svbin.mailhost.domain.com.114.) failed: Permission denied (euid=5000(vmail) egid=5000(vmail) missing +w perm: /usr/local/etc/dovecot/sieve, we're not in group 6(mail), dir owned by 143:6 mode=0775) Dec 9 00:09:59 mailhost dovecot: lda(gessel(a)domain.com): Error: sieve: The LDA Sieve plugin does not have permission to save global Sieve script binaries; global Sieve scripts like `/usr/local/etc/dovecot/sieve/10-move-spam.sieve' need to be pre-compiled using the sievec tool However this fairly clear advice on the failure seems to be contradicted by: # id vmail uid=5000(vmail) gid=5000(vmail) groups=5000(vmail),6(mail) ? dovecot-pigeonhole-0.4.6 = up-to-date with index dovecot2-2.2.15_1 = up-to-date with index uname -a FreeBSD host.domain.com 9.3-RELEASE FreeBSD 9.3-RELEASE #0 r268932: Mon Jul 21 15:51:38 PDT 2014 gessel@host1.domain.com:/usr/obj/usr/src/sys/BARCELONA-13-08 amd64

auth: Error: auth worker: Aborted request: Lookup timed out
by ML mail 01 Feb '15

01 Feb '15

Hello, I was checking the errors on my mailbox server using "doveadm log errors" and found that around 2-3 times a day I get the following error: Jan 29 22:14:43 auth: Error: auth worker: Aborted request: Lookup timed out Any ideas if this is a bad sign? For example some timeout on my side which is too low or is it just an aborted connection from the side of the IMAP client? The configuration on my Dovecot mailbox server can be found here: http://article.gmane.org/gmane.mail.imap.dovecot/80823 It is a Debian 7 box with standard debian packages. Best regards ML

LDAP Quota Limits & Warnings
by Leander Schäfer 30 Jan '15

30 Jan '15

I found this on the dovecot wiki: The following limit names are supported: * *storage*: Quota limit in kilobytes, 0 means unlimited. * *bytes*: Quota limit in bytes, 0 means unlimited. * *messages*: Quota limit in number of messages, 0 means unlimited. This probably isn't very useful. * *backend*: Quota backend-specific limit configuration. * *ignore*: Don't include the specified mailbox in quota at all. As I understood it, all 5 limit categories are valid to use with maildir format while only "storage" and "messages" are valid to use with dmbox format, right? Also the "ignore" limit may appear more than one time for a user - like Trash:ignore and Spam:ignore, right? So I assumed following should work - and it does - except for "ignore" - even though LDAP does not hold multiple values for it - only a single one for each limit: user_attrs = [...] mailQuotaStorage=quota_rule=*:storage=%$, mailQuotaMessages=quota_rule2=*:messages=%$, mailQuotaIgnore=quota_rule3=*:ignore=%$ pass_attrs = [...] mailQuotaStorage=userdb_quota_rule=*:storage=%$, mailQuotaMessages=userdb_quota_rule2=*:messages=%$, mailQuotaIgnore=userdb_quota_rule3=*:ignore=%$ And unfortunately /var/log/maillog tells me: dovecot: imap(abuse(a)netocean.local): Error: user abuse(a)netocean.local: Initialization failed: Failed to initialize quota: Invalid quota root quota: Invalid rule *:ignore=Trash: Unknown rule limit name: ignore Yet /var/log/debug.log sounds a bit more promising ... but then again not really ... dovecot: imap: Debug: Added userdb setting: mail=maildir:/usr/local/www/default/mail/user@mydomain.tld dovecot: imap: Debug: Added userdb setting: plugin/quota_rule=*:storage=1048576 dovecot: imap: Debug: Added userdb setting: plugin/quota_rule2=*:messages=10 dovecot: imap: Debug: Added userdb setting: plugin/quota_rule3=*:ignore=Trash dovecot: imap(abuse(a)netocean.local): Debug: Effective uid=2110, gid=2110, home=/var/vmail/user(a)mydomain.tld/mail dovecot: imap(abuse(a)netocean.local): Debug: Quota root: name=User quota backend=maildir args= dovecot: imap(abuse(a)netocean.local): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=0 dovecot: imap(abuse(a)netocean.local): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=10 dovecot: imap(abuse(a)netocean.local): Debug: Quota rule: root=User quota mailbox=* bytes=1073741824 messages=10 Additionally, if one of the two working quotas (storage & messages) is exceeded than Dovecot sends out a warning from this setting: plugin { quota_warning = storage=90%% quota-warning 90 %u quota_warning2 = storage=75%% quota-warning 75 %u # What message to send to IMAP clients (and SMTP senders) when quota is exceeded? quota_exceeded_message = Quota exceeded, please go to http://MyDomain.TLD for instructions on how to fix this. } No my question is how to provide two different warnings. One for storage like: Sorry, you're mail storage is full. Please delete some. And a second for messages like: Sorry, you've too many messages. Please delete some. Thanks & Best Regards Leander
