[Dovecot] deliver setgid issues
by Brad 12 Jun '06

12 Jun '06

Okay .. have dovecot set up with following settings : userdb static { args = uid=97 gid=97 home=/export/dovecot/mail/%d/%u mail=mbox:/export/dovecot/mbox/%d/%u/ } passdb passwd-file { # Path for passwd-file args = /etc/dovecot-passdb } Passdb works I think in the sense that I can log into dovecot using a regular mail client. The real issue is when I try to deliver any type of mail using dovecot-lda (deliver). deliver is setuid and setgid dovecot .. I event se the static mail dirs above to be owned by dovecot (I know .. a no no .. but wanted to trace down issue) I also have first_valid_uid = 96 and first_valid_uid = 96 Now .. when I try to do this .. echo "A Test Message" | /usr/local/libexec/dovecot/deliver -d existinguser I get this .. master in: USER 1 echo service=deliver dovecot: Mar 11 23:45:24 Info: auth(default): master out: USER 1 echo uid=97 gid=97 home=/export/dovecot/mail//echo mail=mbox:/export/dovecot/mbox//echo/ dovecot: Mar 11 23:45:24 Error: auth(default): deliver: Fatal: setgroups(97) failed: Operation not permitted 97 is the gid for the dovecot user .. which owns just about everything deliver could ever touch. What am I missing ?

[Dovecot] LDA Questions
by Timothy White 12 Jun '06

12 Jun '06

Firstly, if you're out of quota for example, and using postfix, will it need to send a bounce email, or will it do the out of quota error at SMTP time? (preferred) Also, I want a global sieve script to run first, REGARDLESS if the user has their own script. # If there is no user-specific Sieve-script, global Sieve script is # executed if set. #global_script_path = This suggests to me, that it will only execute if no user sieve script is present. As most of my users are going to be virtual, it shouldn't be a problem, but just encase, I'd like to know my global script is being run for all users. Thanks Tim -- Linux Counter user #273956

[Dovecot] ssl_require_client_cert = yes for encrypted connections only
by Rainer Frey 12 Jun '06

12 Jun '06

Hi, is there any way to get dovecot to use "ssl_require_client_cert = yes" for encrypted connections only? For unencrypted connections there can't be any client certificate, and I can't disable unencrypted connections altogether (I limit them by firewall to our own network).

[Dovecot] Expunge is not expunging unless called twice--revisited
by Jeff Blank 12 Jun '06

12 Jun '06

Hi, I'm running dovecot-1.0.beta8 from FreeBSD ports, using mbox mail store. My problem appears to have come up on the list about a month ago, "Expunge is not expunging unless it is called twice". I ran through Bill Boebel's telnet-IMAP session for myself, and I see that his test case is now fixed (as Timo said), but mutt, for whatever reason, uses +FLAGS.SILENT, and I'm still getting the behaviour in Bill's original problem when I telnet and use +FLAGS.SILENT: 1 OK Logged in. 2 select INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft) * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] * Flags permitted. * 1 EXISTS * 1 RECENT * OK [UNSEEN 1] First unseen. * OK [UIDVALIDITY 1148956034] UIDs valid * OK [UIDNEXT 4] Predicted next UID 2 OK [READ-WRITE] Select completed. 3 UID STORE 3 +FLAGS.SILENT (\Deleted) 3 OK Store completed. 4 expunge 4 OK Expunge completed. 5 expunge * 1 EXPUNGE * 0 RECENT 5 OK Expunge completed. After step 4, the message is still in the mailbox with "X-Status: D"; the second expunge is required to remove it. I seem to get the same behaviour with Thunderbird, so is this still a dovecot problem? (I have Thunderbird set up to remove deleted messages immediately, not move to trash or just mark as deleted.) thanks much, Jeff

[Dovecot] Dovecot 1.0beta7: STARTTLS/SSL not wanting to start
by Mike Brudenell 11 Jun '06

11 Jun '06

Greetings - I have been looking at Dovecot with a view to migrating us to it from the Washington IMAP server on our Sun systems. To start our testing we first of all installed the pre-built version of Dovecot from the Blastwave (www.blastwave.org) community supported packaged software site. This was Dovecot 0.99.10.4 and we successfully got it working in our test environment: at first just with regular IMAP, then with STARTTLS too. For the latter we installed a properly signed certificate and it works fine: mail clients can connect, use STARTTLS and then use the encrypted connection. I then downloaded the source code for Dovecot 1.0beta7 and built this myself from source, against the OpenSSL 0.9.8 libraries. I configured Dovecot to use the same certificate and key files as had been used for the earlier version we had just tried out. Whilst 1.0beta7 works fine for regular IMAP it just does not want to start SSL using STARTTLS at all. The error that is getting logged in the syslog file is: <date etc> ... dovecot: [ID 107833 mail.warning] imap-login: SSL_accept() failed: error:140D308A:SSL routines:TLS1_SETUP_KEY_BLOCK:cipher or hash unavailable [ddd.ddd.ddd.ddd] I see in the archived for the list archives that this same problem was asked about for 1.0beta3 but without a solution I could see. Could someone offer any insight/help, please?

[Dovecot] beta8: complaint about tilde at startup
by Jeff A. Earickson 11 Jun '06

11 Jun '06

Timo, After installing beta8 on Solaris 10 sparc and starting it for the first time, I noticed this in my syslog: May 14 19:35:45 emerald dovecot: [ID 475045 mail.info] Dovecot v1.0.beta8 starting up May 14 19:35:47 emerald dovecot: [ID 536776 mail.error] stat(~) failed: No such file or directory The only appearance of the tilde (~) in my dovecot.conf is here: default_mail_env = mbox:~/mail:INBOX=/var/mail/%1u/%u:INDEX=~ Is the INDEX definition wrong? Or is this a bug? My setup: Solaris 10, mbox format, home directories are local UFS filesystems, INBOX is an NFS-mounted filesystem from another S10 box (NFS version 4). Jeff Earickson Colby College

[Dovecot] maildir quota not including INBOX
by Bill Boebel 11 Jun '06

11 Jun '06

The maildir quota plugin doesn't appear to be including the INBOX in the quota calculation that is reported by GETQUOTAROOT. I took a look at the code and it appears that in this file "src/plugins/quota/quota-maildir.c", the function "maildirsize_recalculate" relies on all of the folders being listed when "maildir_list_init" is called. However the INBOX is not included in that listing, so its current storage size is not included. I couldn't figure out what patch would be needed to fix this, but I'm sure it is something simple. Any ideas? Bill

[Dovecot] LIST command ignores "hidden=yes" for default namespace
by Bill Boebel 11 Jun '06

11 Jun '06

I'm not sure if this is a bug or just an undesirable feature, but when I have our namespace configured to match Courier's "INBOX." functionality, Dovecot forces me to also define a default namespace (with no prefix). Without the default namespace defined I get "NO Unknown namespace." errors when trying to subscribe or unsubscribe folders. So I have configured my namespaces like this: namespace private { separator = . prefix = INBOX. inbox = no } namespace private { separator = . prefix = inbox = yes hidden = yes } However with this configuration, LIST commands ignore the "hidden = yes" setting on the default namespace and IMAP clients end up displaying an identical folder listing twice... 2 list "" "*" * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.spam" * LIST (\HasNoChildren) "." "INBOX.Trash" * LIST (\HasNoChildren) "." "INBOX.Sent" * LIST (\HasNoChildren) "." "INBOX.Drafts" * LIST (\HasNoChildren) "." "INBOX.RSS" * LIST (\HasNoChildren) "." "INBOX.test" * LIST (\HasNoChildren) "." "INBOX.test2" * LIST (\HasNoChildren) "." "spam" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "Drafts" * LIST (\HasNoChildren) "." "RSS" * LIST (\HasNoChildren) "." "test" * LIST (\HasNoChildren) "." "test2" 2 OK List completed. Again, I am not sure if this was intended, but either way it is undesirable for us. I even had a couple customers delete one of their duplicate folders thinking that was safe, but it deleted both folders - of course. To force Dovecot to hide mailboxes in the default namespace I made the following change: src/imap/cmd-list.c: @247 + if (ns->hidden) { + return; + }
