Bug (?) while listing imap folder
by Alexandros Soumplis 13 Nov '14

Dear All, I think I've hit a bug after migrating our mail server to the newest version of dovecot (version 2.2.15). When I try to list all imap folders for one user the imap process crashes. The listing to a specific folder (ex. INBOX) works fine, only the "*" crashes. Client side: --------------------- [root@mb log]# telnet 127.0.0.1 143 Trying 127.0.0.1... Connected to 127.0.0.1.

Query: SELECT "INBOX" permission denied
by Don Levey 12 Nov '14

12 Nov '14

Yesterday I was forced to migrate servers due to a hardware failure. I have been able to bring up my mail server, and set up Squirrelmail and Dovecot. I am able to access (via Squirrelmail) all users' mail except one - which happens to be my wife's, so it would be really helpful if I could get that working too. I am able to log in, but see the following message in the main pane: ERROR: Could not complete request. Query: SELECT "INBOX" Reason Given: [NOPERM] Permission denied I have see similar errors in my searches, but they all relate to *creating* files (inbox, sent, etc). The files do already exist here, they used to work in the same directory structure on the old server configuration, and I can see no relative difference between this user's files/permissions and working users' files/permissions. Suggestions are welcome; thanks in advance, -Don Here are the vitals: Version: 2.2.10 OS: CentOS 7 # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-123.9.3.el7.x86_64 x86_64 CentOS Linux release 7.0.1406 (Core) ext3 auth_mechanisms = plain login disable_plaintext_auth = no log_path = /var/log/dovecot.log mail_location = mbox:/home/%u/~mail:INBOX=/var/spool/mail/%u mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } ssl = required ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } [root@dungeon sandra]# ls -la /var/spool/mail total 2097152 drwxrwxr-x. 2 root mail 4096 Nov 11 22:10 . drwxr-xr-x. 16 root root 4096 Nov 11 14:21 .. -rw-rw----. 1 sandra mail 625547161 Nov 11 21:32 sandra -rw-rw----. 1 spamtrap_000 mail 26773946 Nov 11 20:53 spamtrap_000 -rw-rw----. 1 spamtrap_001 mail 3092961 Nov 11 22:10 spamtrap_001 -rw-rw----. 1 spamtrap_002 mail 8778257 Nov 11 00:03 spamtrap_002 -rw-rw----. 1 spamtrap_003 mail 63579856 Nov 11 21:21 spamtrap_003 Her directory: [root@dungeon .imap]# ls -la total 100 drw-------. 25 sandra sandra 4096 Jul 1 2008 . drwx------. 4 sandra sandra 4096 Nov 10 10:48 .. drwx------. 2 sandra sandra 4096 Jul 1 2008 bday drwx------. 2 sandra sandra 4096 Jul 1 2008 beads drwx------. 2 sandra sandra 4096 Jul 1 2008 books drwx------. 2 sandra sandra 4096 Jul 1 2008 Drafts drwx------. 2 sandra sandra 4096 Jul 1 2008 ham drwx------. 2 sandra sandra 4096 Nov 11 21:39 INBOX drwx------. 2 sandra sandra 4096 Jul 1 2008 Sent drwx------. 2 sandra sandra 4096 Jul 1 2008 spam drwx------. 2 sandra sandra 4096 Jul 1 2008 Trash drwx------. 2 sandra sandra 4096 Jul 1 2008 Work A working directory: [root@dungeon .imap]# ls -la total 56 drwx------. 14 spamtrap_003 spamtrap_003 4096 Oct 23 19:22 . drwx------. 3 spamtrap_003 spamtrap_003 4096 Nov 10 09:15 .. drwx------. 2 spamtrap_003 spamtrap_003 4096 Jun 8 08:40 Deleted Messages drwx------. 2 spamtrap_003 spamtrap_003 4096 Aug 11 2011 Drafts drwx------. 2 spamtrap_003 spamtrap_003 4096 Mar 18 2011 ham drwx------. 2 spamtrap_003 spamtrap_003 4096 Nov 11 21:21 INBOX drwx------. 2 spamtrap_003 spamtrap_003 4096 Oct 18 2013 Sent drwx------. 2 spamtrap_003 spamtrap_003 4096 Aug 28 09:55 Sent Messages drwx------. 2 spamtrap_003 spamtrap_003 4096 Oct 6 20:11 spam drwx------. 2 spamtrap_003 spamtrap_003 4096 Nov 11 21:21 Trash

I am using dovecot in mbox format. I'm going to set to leave the 30-day mail to the server with the mail client. The other day, some of email was received duplicate When receive mail. Mail does not arrive between Nov 4 11:09:03 and Nov 4 11:13:25. There should be the 259 (274-15) messages at the time of Nov 4 11:09:03 on the server from the log. But there were the 280 messages at the time of Nov 4 11:13:25 and 21 messages was a duplicate.

Disabling SSLv3 protocol
by Timo Sirainen 11 Nov '14

11 Nov '14

Since people are now talking about the SSLv3 security hole and how to disable it, here's a thread where you can talk about that. In Dovecot v2.1+ you can disable SSLv3 by setting: ssl_protocols = !SSLv2 !SSLv3 In older versions you'd have to patch the source code. Attached a patch against v2.0. I don't know if there are any clients that would break by disabling SSLv3. I'd expect all the clients to use the system (or otherwise generic) SSL libraries, which would automatically choose the TLS protocol over SSL. So my guess is that unless somebody is using over a 10 year old client there wouldn't be any problems. Maybe some old mobile phones might be using SSL.. If you find out about any clients that require SSLv3 I'd like to know about it. For Dovecot v2.3 I could maybe disable SSLv3 by default if there's no real need for it. (Also: Don't be confused by SSL/TLS protocols vs. SSL port/STARTTLS, as described in http://wiki2.dovecot.org/SSL. For example https://en.wikipedia.org/wiki/Comparison_of_email_clients#SSL_and_TLS_suppo… is irrelevant here.)
