[Dovecot] POP (dot) locks
by Christian Balzer 09 Apr '06

09 Apr '06

Hello, just to soothe my paranoia from many years of qpopper usage, which enforces solitary access to a POP mailbox. Only one login per user is possible at the same time and if a session terminates w/o qpopper being properly notified it will remain locked for some time, 30 minutes by default. With dovecot (0.99.10.4) one can login multiple times (using POP, with IMAP of course this comes as no surprise :) and thus I presume this bit from the configuration: --- # Should we create dotlock file even when we want only a read-lock? Setting # this to yes hurts the performance when the mailbox is accessed simultaneously # by multiple processes, but it's needed for reliable reading if no other # locking methods are available. #mbox_read_dotlock = no --- means that if the only other reading accesses to a (mbox style in this case here) mailbox are via other dovecot processes everything will be fine?

[Dovecot] imap idle on non-inbox?
by Collin Grady 22 Oct '04

22 Oct '04

Can this be done with dovecot? I really like the imap idle feature, but it doesn't work for me because I sort my mail into folders with procmail, so it only notifies me when one drops into inbox and not a subfolder. Is there just an option for this I'm missing, or does support for this not exist yet? Also, I don't think its a client issue as I watched the traffic with tcpdump and it only announced anything for inbox, messages dropping into other folders caused no traffic. -- Collin Grady BOFH excuse #347: The rubber band broke

[Dovecot] Plaintext Authentication from Localhost
by Paul C. Bryan 06 Sep '04

06 Sep '04

Hi: It appears that at least at one time, Dovecot supported plaintext authentication from localhost, even if disable_plaintext_auth = yes. To wit, the example configuration file reads: # Disable LOGIN command and all other plaintext authentications unless # SSL/TLS is used (LOGINDISABLED capability). Note that 127.*.*.* and # IPv6 ::1 addresses are considered secure, this setting has no effect if # you connect from those addresses. #disable_plaintext_auth = yes On brief inspection of the code, there doesn't seem to be any such support. This is corroborated by the fact that 0.99.10 (Debian package) behaves by disallowing plaintext authentication via connections on localhost. This is a particularly useful feature, as local webmail clients can safely authenticate via the local interface without requiring secure authentication. So, the question is, is Dovecot supposed to support plaintext auth via localhost even if disallowed in dovecot.conf? If so, any suggestions as to what I may be doing wrong? Yours truly, Paul C.

[Dovecot] What about saving your INBOX at ~/mbox ?
by Nico Kadel-Garcia 23 Aug '04

23 Aug '04

Hi, folks. I'm testing out RedHat's "Fedora Core 2" release, which has switched from the old WashU imapd to dovecot-0.99.10. Overall, this looks like a really, really good move on their part: it looks like a very sweet little tool without some of the ingrained idiocy of Mark Crispin insisting that every home directory consist of nothing but mbox files and allowing you to use a configurable subdirectory by default, ~/mail. Cool. There is one feature of the old WashU imapd that I miss, though. That daemonn could be configured to automatically transfer the user's email to the "~/mbox" upon activation of the daemon, effectively reducing the size of the /var/spool/mail/{username}" mail spool and helping keep the user's disk usage in their home directories, not in /var/spool/mail. This can be a good thing for various reasons. But I don't see any way to enable that behavior for dovecot. Is there something I'm missing, or do folks feel it would be reasonable to add? -- Nico Kadel-Garcia Systems Engineer Mitsubish Electric Research Lab <nkadel(a)merl.com>

[Dovecot] The Status: header is forced
by Olivier Tharan 21 Jun '04

21 Jun '04

Hi, I started testing dovecot for our next POP/IMAP server (nearing production state), and noticed that the Status: header is always added, with a value of 'O' or 'RO'. This happens in `lib-index/mbox/mbox-rewrite.c'. This does not seem to happen in the Maildir case. Is the Status: header really needed in every case? This breaks mutt which displays mails with a 'O' flag instead of 'N'. My dovecot is 0.99.10.4 (FreeBSD port), but the behavior is still the same in the CVS version. -- olive

[Dovecot] 0.99.10.5 released
by Timo Sirainen 19 Jun '04

19 Jun '04

One more bugfix since rc2: - Maildir: synchronization might have sometimes set wrong flags to messages, or crash completely Quite rare because we were lucky before :) And list of all the changes one more time: v0.99.10.5 2003-12-27 Timo Sirainen <tss(a)iki.fi> + MySQL authentication, patch by Matthew Reimer + --with-moduledir configure option - mbox: APPEND reversed given \Draft and \Deleted flags - mbox: "LF not found" errors happened sometimes when X-IMAPbase header was updated. Possibly corrupted mbox sometimes. Thanks to Fabrice Bellet for finding this bug. - Custom flags couldn't be unset - Maildir: make sure ":2," is appended to filename when moving mails from new/ to cur/. - Maildir: synchronization might have sometimes set wrong flags to messages, or crash completely - Maildir: RENAME xx inbox.xx didn't result as uppercased ".INBOX.xx" directory which then couldn't be accessed - Don't crash with RAND_bytes() error messages anymore. This mostly happened with Fedora/RedHat.

[Dovecot] Serve list archives by dovecot IMAP
by Kenneth Porter 02 Jun '04

02 Jun '04

Has anyone considered setting up a Dovecot public server to serve the list archives by IMAP? Or does Dovecot not do anonymous read-only access? (I note by comparison that the Cyrusoft Mulberry list archives are served by an IMAP server. <http://www.cyrusoft.com/mulberry/support/anonimap.html>) It should be sufficient to set up Dovecot on some server in the dovecot.org domain and subscribe it to the lists.

[Dovecot] Dovecot + SSL + Fedora
by David Keegel 02 Jun '04

02 Jun '04

I've been seeing the Dovecot/SSL/Fedora 1 problem. I have a dovecot server which tends to die at least once a day, with messages like these :- May 24 13:44:44 mail pop3-login: RAND_bytes() failed: error:24064064:random number generator:SSLEAY_RAND_BYTES:PRNG not seeded May 24 13:44:44 mail dovecot: Login process died too early - shutting down I noticed Timo's email about this at: http://www.dovecot.org/list/dovecot/2004-May/003316.html with the patch that just ignores the return code of RAND_bytes(). Would disabling SSL in dovecot.conf also be a reasonable way of avoiding the problem of dovecot crashing? My plan is to set ssl_disable = yes and also take out pops and imaps from protocols. That is a lot easier for me than getting source, patching it, re-compiling and re-installing. We are using Fedora Core 1 (fedora-release-1-3 i386 rpm) Dovecot 0.99.10 (dovecot-0.99.10-4 i386 rpm) OpenSSL 0.9.7a (openssl-0.9.7a-33.10 i386 rpm) ___________________________________________________________________________ David Keegel <djk(a)cybersource.com.au> http://www.cyber.com.au/users/djk/ Cybersource P/L: Linux/Unix Systems Administration Consulting/Contracting

Changes since .4: + MySQL authentication, patch by Matthew Reimer - mbox: APPEND reversed given \Draft and \Deleted flags - mbox: "LF not found" errors happened sometimes when X-IMAPbase header was updated. Possibly corrupted mbox sometimes.
