[Dovecot] Dovecot and quotas
by mikael 22 Jul '06

22 Jul '06

Hello, I have succesfully installed dovecot version 1.0.rc2 on my Debian Sarge. I have configured quotas (just for tests) like this : == dovecot.conf == ... auth default { mechanisms = plain passdb pam { } userdb passwd { } } protocol imap { mail_plugins = quota imap_quota } plugin { # quota = 10 Mb quota = dirsize:storage=10240 } ... ================== Quotas works without problem : 10Mb for all users... But i would like quotas per user and kept thi default value of 10Mb... How to override this default value ? How to do peruser-quota with "passwd" userdb (or "passwd-file") ? Really thanks for your help, -- Mikaël,

[Dovecot] cmusieve plugin
by Stuart Sears 21 Jul '06

21 Jul '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys I have been doing a lot of searching, but maybe I am being dim (not unheard of!). I have dovecot-1.0rc2 built and running on Fedora Core 5. The wiki page (dated yesterday) states that I need the cmusieve plugin to use sieve scripts with the dovecot lda. Is this a new development? They seem to work quite happily on my soon-to-be retired 1.0-beta7 debian box without an extra plugin. secondly, if it is now necessary, where do I get this plugin from? (this may be the dim part) I have a cvs checkout of the dovecot sources, but I see nothing obviously connected to cmusieve anywhere in the source tree If this is in a different module, then can someone let me know the name of it, so that I can check it out of CVS as well?

[Dovecot] Migrating to dovecot
by Johann Spies 21 Jul '06

21 Jul '06

I do not have much experience in setting up imap servers - only that I have tried several and experienced the same problem with all of them. I suppose that is because I do not really know the in's and out's of an imap server. What I want to do is to setup an IMAP server on my PC with full access to all the emails already there in a maildir structure. I have the following setup: fetchmail -> procmail -> maildir exim for outgoing mail. When I install an imap server, I loose access to my present emails in ~/Mail and most imap-servers (dovecot included) seems to create a new structure within ~/Mail. ~/Maildir is a symlink to ~/Mail. Now my questions: 1. How do I set up dovecot to serve the present maildir to the user? 2. Related to 1: How do I migrate my emails to the new imap-maildir structure without losing any? 3. How would my present procmail-setup change? At the moment I have entries like the following: MAILDIR=$HOME/Mail # you'd better make sure it exists DEFAULT=$MAILDIR/Ander/new # completely optional :0: * X-Spam-Flag: YES saspam/new :0: * ^List-Id: <users.spamassassin.apache.org> spamassassin/new ...

[Dovecot] Soft limit quota
by Philipe Gaspar 20 Jul '06

20 Jul '06

I'm using dovecot on our new mail server and it is pretty good. But I have a problem regarding quota limits, I am using quota plugin on imap, pop3 and LDA, the deliver agent blocks new messages for delivery, like hard quota. I'd like to use LDA with quota plugin regarding soft quota. Thanks for any clues, -- Philipe Gaspar Universidade Salvador Fone:+55 (71) 3273-8592

[Dovecot] Patch suggestion
by Renaud Allard 20 Jul '06

20 Jul '06

Hi, Would it be possible to make a change in the configure file to search for gssapi.h in <kerberosV/gssapi.h> if it fails to find it in <gssapi/gssapi.h>? That would allow to compile dovecot with gssapi easily on OpenBSD without patching it.

[Dovecot] making Dovecot match Courier POP3 UID's
by Jeff Tucker 20 Jul '06

20 Jul '06

Hi, guys. I've read the information in the Wiki about making dovecot's UID's match Courier's UID's in the POP3 server, so that a UIDL command on either server will return the same UID's for the same group of messages. However, what I've read doesn't match what I'm seeing in Courier. Courier appears to keep the UID numbers for messages that it uses for the POP3 server separate from the UID numbers for the IMAP server. Courier has a file: courierpop3dsizelist which has a line for every message, like: 1129610881.6075832619.blade4:2,S 2361 1478:1065670602 1129727025.1168007000.blade1:2,S 14718 1479:1065670602 1130005953.3295720403.blade5:2,S 1554 1481:1065670602 1130108068.0849623942.blade5:2,S 8246 1482:1065670602 The first column is the maildir filename, the last column is the UID that the POP3 server uses and the UID validity. Both are used to create the UID number returned by UIDL. The IMAP server uses a completely different UID number that's stored in courierimapuiddb. So, it seems to me that dovecot can't ever match Courier's UID numbers for the POP3 server unless it reads and interprets this courierpop3dsizelist file. My Courier-IMAP installation is Courier-IMAP 4.0.6. Any ideas? This is a real hassle because it means I can't switch the POP3 server from Courier to Dovecot or, if I do, lots of my users will download every message again which is just unacceptable. Thanks Jeff

[Dovecot] proxy performance
by Vincent Fox 19 Jul '06

19 Jul '06

Can anyone speak to experience using Dovecot proxy to frontend for multiple back-end servers in a "large" environment? We have 50,000+ mailboxes spread across 10 POP/IMAP servers. We'd like to be able to put in a front-end setup on our load-balancer of 4 dual-CPU Sun systems. I am a bit concerned about performance issues although from what I have read the proxy can be set not to fork, which improves performance a lot. Still concerned about whether SSL loading will be an issue. We'd like to use LDAP to look up the reference to which mail-store a user is on. I see that the Wiki refers to SQL. The mailing list indicates passwd-file also works. Not clear about LDAP.

[Dovecot] /var/spool/mail directory size and subdirectories
by David Lee 19 Jul '06

19 Jul '06

(Complete newbie to dovecot. I hope what follows isn't something I've missed in some FAQ somewhere...) On a traditional UNIX filesystem with UW-IMAP several years ago, we encountered major performance problems when "/var/spool/mail/" got big (we would currently be ~20,000 entries). This was due to the inefficiency of the UNIX filesystem when creating and deleting the lockfiles (etc.) in a directory of that size. We worked around that (all those years ago) with a local source-code mod to UW-IMAP ("c-client") to use subdirectories "/var/spool/mail/00/" to "/var/spool/mail/99/" based on a trivially simply "uid mod 100" algorithm. (Our uids are random; our usernames are not.) Thus we had 100 subdirs each of about 200 entires. Efficiency and performance vastly improved, and we've been running like that ever since. Now we are considering migrating to dovecot... Does dovecot do file creation/deletion in this (or similar shared) directory? (And so would it be liable to the same inefficiency problems?) Is there some means in the "dovecot.conf" file to specify an INBOX pattern as "/var/spool/mail/%ZZZ%/%u" where "%ZZZ%" could be algorithmically specified as (say) "user-uid mod 100"? -- : David Lee I.T.

[Dovecot] strange dropping of Word.doc-attachements - sendmail dovecot RHEL4
by Götz Reinicke 19 Jul '06

19 Jul '06

Hi, we have a strange problem: two of our users informed me, that they aren't able to send word-.doc-files anymore while othe attachements work fine. The e-mail gets deliverd, but the attachement is dropped. This happens using the latest thunderbird 1.5.x and mac os x. The e-mail is also not saved in the send-drawer. If the users send the same e-mail to the same recepient using an other mailclient, there is no problem. Other users (like me) using the same systemsettings and software versions don't have the problem. The server is RHEL 4 (2.6.9-kernel), sendmail 8.13.1 and dovecot 0.99. We use Mailscanner and spamassassin too, but as only the two users do have the problem I'm looking for some help to track this problem down. Any ideas??

[Dovecot] Masking INBOX.INBOX

18 Jul '06

I am using dovecot and trying to make it compatible with my a BincIMAP installation. BincIMAP uses a scheme similar to Courier-IMAP, so I set up this default_mail_env: default_mail_env = maildir:~/Maildir And this namespace: namespace private { separator = . prefix = INBOX. inbox = yes } Which mostly works as expected, but I now see an "INBOX" subfolder of "INBOX" in LIST: * OK Dovecot ready. 1 login ben ******** 1 OK Logged in. 2 list "" "*" * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.INBOX" * LIST (\HasNoChildren) "." "INBOX.Drafts" * LIST (\HasChildren) "." "INBOX.Jabber" * LIST (\HasChildren) "."

I've toyed with various configurations to try to hide it, but nothing seems to work. What's annoying is this situation: 3 LSUB "" "*" * LSUB () "." "INBOX.Spam" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Drafts" 3 OK Lsub completed. 4 SUBSCRIBE "INBOX" 4 OK Subscribe completed. 5 LSUB "" "*" * LSUB () "." "INBOX.Spam" * LSUB () "."

I then "SUBSCRIBE" in 4 to "INBOX" and dovecot translates that to subscribing to "INBOX.INBOX". Not a huge deal, but it does cause Thunderbird to act weirdly (although Thunderbird allows me to UNSUBSCRIBE to "INBOX" and still get new mail), but I'm not sure what the effect will be on other clients. Any ideas? Thanks, Ben

[Dovecot] Getting maildir++ quotas working
by Bill Boebel 18 Jul '06

18 Jul '06

Can somebody post details for how to get maildir++ quotas working in the latest CVS? I have tried but can't get the CAPABILITY string to show "QUOTA"; and the GETQUOTAROOT command is recognized, but returns nothing... 2 GETQUOTAROOT INBOX * QUOTAROOT "INBOX" "" * QUOTA "" () 2 OK Getquotaroot completed. These are the settings I have... am I missing something? protocol imap { mail_plugins = imap_quota quota mail_plugin_dir = /usr/lib/dovecot/imap } plugin { quota = maildir imap_quota = maildir } Here are some more details: Dovecot is creating the maildirsize file in my maidir, and it seems to show correct storage used calculations, but the first line which should contain my storage limits is blank. So I suspect that I am not returning a valid quota value from the user database. I am returning what my old Courier-IMAP wants to see "1073741824S,4000C"... if the format for Dovecot is different, what should the format be? So there are two problems that I am trying to resolve, but I'm not sure how to go about fixing it. Any help would be greatly appreciated: (1) Dovecot isn't announcing QUOTA support in the capability string. (2) Dovecot isn't getting a valid quota limit, which I assume is breaking the GETQUOTAROOT command. Thanks, Bill

So I guess this is dovecot related. My IMAP client is thunderbird on Linux, but I have also seen the problem with sylpheed on OpenBSD. Any help or hint appreciated.

[Dovecot] Postfix Virtual Users and Directory Permissions
by Michael Starks 18 Jul '06

18 Jul '06

I have followed the instruction here: http://www.postfix.org/VIRTUAL_README.html#virtual_mailbox There are five virtual domains configured and each directory containing each domain is owned by one UID/UID with permissions of 700. I can send mail to each domain and it is stored in the appropriate Maildir under the correct directory. The system is OpenBSD 3.8 STABLE. So far, so good. Now comes Dovecot. What I would like to do is to have one set of credentials for 4 of the domains, and another for the remaining. I would also like to *not* use a database backend for authentication at this time and would prefer to stick with standard UNIX /etc/passwd and /etc/shadow. Considering the directories are all owned by one user, does Dovecot need to be configured to use the same user as auth_userdb = static? That would make sense. What I'm not clear on is how Dovecot would know which domains are associated with which user, and does the user need permissions to those directories or is that handled by impersonation? Thanks in advance.

[Dovecot] pop3 auth problem solved!
by Bruce Lane 16 Jul '06

16 Jul '06

Fellow techies, OK... This is going to go down as one of those "D'Oh!" moments in the world of computers. Boy, do I feel dumb... In short: I found the problem. One miserable little line in 'dovecot.conf' called 'auth_default_realm =.' I had this set to 'bluefeathertech.com,' thinking it was necessary to do so. I was wrong, at least for my environment, and the stupid clues were right in front of me in the logfile all the time! For the benefit of others who may run into this: Setting a domain name in this entry causes that domain name to be automatically appended to usernames when they log in. No wonder nothing ever matched in /etc/passwd! My deepest thanks to Frank Cusack for giving me the idea. Something he said in his post, in response to my initial one, got me thinking about things getting appended to the user name, and the rest is history. pop3 and pop3s both work just fine now, thanks. ;-) Keep the peace(es). -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

[Dovecot] pop3 authentication problems: Still got 'em...
by Bruce Lane 16 Jul '06

16 Jul '06

Fellow users, This is just a heads-up to let the list know that I'm still unable to get ANY sort of pop3 or pop3s authentication to work with Dovecot. Just as a sanity check, I set up an entirely separate system, running FreeBSD 6.1 production, postfix 2.3, and Dovecot 1.0rc2, as a testbed. I got the exact same problem that I had with the NetBSD 3.0 production server, specifically that Dovecot refuses to authenticate a user with either basic pop3 or pop3s. The way I see it, I may as well try to get basic pop3 working first. If it doesn't, pop3s will never work. This first quote is taken from the mail client (Pegasus) trying to establish a regular, unencrypted pop3 session. -=-=-=-=-=-=- [*] Connection established to 192.168.42.80 >> 0058 +OK AVG POP3 Proxy Server 7.1.368/7.1.394 [268.10.1/389] << 0013 USER kyrrin >> 0005 +OK << 0016 PASS XXXXXXXXX >> 0029 -ERR Authentication failed. -=-=-=-=-=-=-=- As you can see, the user ID of 'kyrrin' is getting passed as just that, and Dovecot at least seems to recognize it. I say this as a prefix to the next log clip, which will be the corresponding entry from /var/log/maillog, in which the user name is being presented (for whatever reason) in FQDN format. Note that pam was added just as an experiment. It failed too, despite the presence of a 'dovecot' file, containing the following, in /etc/pam.d -=-=-=-=-=-=-=- pioneer# cat /etc/pam.d/dovecot auth required pam_unix.so nullok account required pam_unix.so pioneer# -=-==-=-=-=-=- This would be the /var/log/maillog entry corresponding to the above-referenced Pegasus session. -=-=-=-=-=-=-=- Jul 16 11:24:38 pioneer dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.42.80rip=192.168.42.40 resp=AGt5cnJpbgBocDIxZHZlbTc= Jul 16 11:24:38 pioneer dovecot: auth(default): pam(kyrrin(a)bluefeathertech.com,192.168.42.40): pam_authenticate() failed: authentication error Jul 16 11:24:38 pioneer dovecot: auth(default): cache(kyrrin(a)bluefeathertech.com,192.168.42.40): User unknown Jul 16 11:24:40 pioneer dovecot: auth(default): client out: FAIL 1 user=kyrrin(a)bluefeathertech.com Jul 16 11:24:49 pioneer dovecot: pop3-login: Aborted login: user=<kyrrin(a)bluefeathertech.com>, method=PLAIN, rip=192.168.42.40, lip=192.168.42.80 -=-=-=-=-=-=-=- This next bit is the auth default section of my dovecot.conf file.

Thanks in advance for any assistance. I'm really starting to get seriously upset about this, enough to give thought to qpopper over Dovecot. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"
