This was on Dovecot 1.2.15 on Debian Squeeze. My tool? It's called "midget" and retrieves documents from an IMAP box based on their mid: or cid: identifier, as per RFC 2392.

dovecot.org slow & imap search now blazing fast
by Laeeth Isharc 14 Jan '15

14 Jan '15

Hi. In case you were not aware, I wanted to let you know that dovecot.org has been very slow (often almost unusable) for at least several days now. Also, I upgraded my dovecot from 2.2.10 to 2.2.15. Thank you for fixing IMAP search. I have c. 2mm messages, and it had become unusable before but it is now very fast. (I saw a reference to an optimisation on the mailing list from back in Oct 2013, so maybe that was it). Regards, Laeeth

pigeonhole ereject vs reject
by Robert Blayzor 14 Jan '15

14 Jan '15

Currently pigeonhole supports reject which would generate a NDR for each message. (If I understand the current documentation) Using Dovecot LMTP it would be more optimal to kick a 5xx back to the primary MTA to reject the delivery rather than generating more back scatter NDRs. Anyone know if this is possible now (to forgo the NDR)'s or do we need to wait for ereject ? If so, how much work is involved? -- Robert inoc.net!rblayzor http://inoc.net/

I'm setting up a new server and am planning on using blowfish crypt. This page from the wiki http://wiki2.dovecot.org/Authentication/PasswordSchemes says the password will begin with $2a$, however mine are starting $2b$.

dovecot and glusterfs
by Michael Schwartzkopff 14 Jan '15

Hi, I did some experiments with dovecot on a glusterfs on the active nodes without a director. So I had concurrent access to the files. With the help of the available documentation about NFS and fcntl locks I managed to find out the following: With the plain mbox format dovecot seems to apply and to honor the fcntl locks. But since this format is not used any more in real setups, it is useless. With mdbox and maildir format I could reliably crash my mail storage just by delivering … [View More]

Moving or "upgrading" from MD5 to SSHA512
by Jyri Hovila [Turvamies.fi] 13 Jan '15

Hello, world! I have a long-running Dovecot & Postfix installation using PostgreSQL back-end. Until now I've been using MD5 hashing but would like to "upgrade" to the salted SSHA512. Is there a way to configure Dovecot so that it would automatically detect the type of the hash stored in the database, so that users who have changed their password (and thus being hashed with SHA512) and users still having an MD5 hash would both be able to authenticate at the same time?

[PATCH] Make Delivered-To optional

Hi, I've read at least one e-mail on this list about making delivered-to in lmtpd optional, but now I need this too, so I made a patch. The default remains as is now (enabled). Rationale: I would like to dsync users and I have catchall POP mailboxes (meaning: a single mailbox gets the mails for a lot of e-mail addresses). If I deliver the e-mails to Dovecot's lmtpd as the original RCPT TO, the Delivered-To header can be used for the POP client to sort the messages on their side to the … [View More]

Re: Maildir permissions on creation?
by Von Random 13 Jan '15

13 Jan '15

Yes, and it is not my use case, sadly. ACLs are meant for imap, not filesystem access and mail_access_groups is also useless for some reason. It just does not change anything. Probably because I don't use mail_location and variables when I provide path for home. (It's stored as is in a database on mailbox creation.) 26.12.2014, 12:07, "Tobi" <tobster(a)brain-force.ch>: > Have you checked the dovecot wiki for 'filepermissions in shared mailboxes' ? > Explains how dovecot set ACL … [View More]when creating mailboxes > > Am 26.

Dovecot on Fedora 20 or 21

Hello, Is anyone running Dovecot on either a Fedora 20 or 21 system? I'm having an issue, on a system reboot, which I admit does not happen often, Dovecot fails to start in the systemctl list, output is status failed. The issue seems to be Dovecot can not bind to the ipv6 address. Now later if I manually log in to the box and start dovecot it works just fine no problems. I've googled and seen similar issues to this. Does anyone have a solution? Thanks. Dave.

Adding the user postboxes to replication using "doveadm replicator add '*' " syncs the mailboxes as expected. Unfortunately both of the servers does not propagate any changes, e.G. new mail in Sent folder. Removing and adding the mailboxes … [View More]

Both servers are CentOS 6.6 x64. Replication status for the problematic user: [root@deoveadm2 ~]# doveadm replicator status username username priority fast sync full sync failed username low 42:10:59 42:10:59 y I tried to reindex the problematic mailbox, tried to restart both mail servers but the issue still here.

Kerberos problems with /dev/null as dovecot home
by Roland Hopferwieser 07 Jan '15

07 Jan '15

Hi, this is for documentation if someone else has the same problem. After migration from Dovecot 1 to 2.2. it was no longer able use Kerberos (Heimdal). I found out that dovecot tries to read ~/.krb5/config in the home of the dovecot user. This file doesn't need to exist, but if the home is set to /dev/null, it will not work. Maybe it would be nice to have an error message for this case. Regards, Roland

Crashes with tracebacks
by Timothe Litt 05 Jan '15

05 Jan '15

Crashes, redux. I hope I have provided all the information required for a solution. Many thanks in advance for having a look. I have 71 core files for a user, that all happened in the space of about 6 hours. It appears that mail delivered to 'Junk E-mail' is being accessed. I suspect they're all the same issue. I saw the same syslog entry a while back; did a resync & enabled process dumps. Naturally, it went away -- until this cluster of crashes. File system is ext3. It is NFS … [View More]mounted by other machines, but only the local machine should be touching the mail directories. The user does not have an interactive login - it's an e-mail only account. This user's IMAP client is AppleMail. The delivery agent is procmail; Junk is detected by spamassassin; clamav is also present. pop3 is configured, but I don't think anyone uses it.

mdbox GUID
by Nagy, Attila 04 Jan '15

04 Jan '15

Hi, The dbox page says: "Each message has a 128 bit globally unique identifier (GUID)" I guess this is what guid_128_generate() generates. Is this believed to be really globally unique? As far as I can tell, in the current architecture they are -given there are enough time precision-, because all dovecot daemons are single threaded, so they have concurrency but doesn't have parallelism (they are not multi threaded). I would like to list all of the messages, with this GUID as the unique … [View More]

ntlm_auth random failures with dovecot
by Jason Gunthorpe 04 Jan '15

04 Jan '15

I'm still a bit fuzzy on exactly what has blown up here since my 1.2 install (or maybe it was broken then and I never noticed), but it looks like the way dovecot is calling out to ntlm_auth is violating the --helper-protocol=squid-2.5-ntlmssp scheme. The issue is how it handles simultaneous clients connecting - for instance launching thunderbird with NTLM auth creates multiple imapds that all have to be auth'd. Since dovecot doesn't (and apparrently didn't in 1.2?) serialize this it ends up … [View More]

[PATCH] LAYOUT=imapdir is broken in v2.2
by Jason Gunthorpe 04 Jan '15

04 Jan '15

The next thing I noticed in my v1.2 -> 2.2 upgrade is that mail_location = maildir:[..]:LAYOUT=imapdir is broken, the symptom is dovecot returning this to the client when requesting any mailbox beyond INBOX: Character not allowed in mailbox name: ' Which is actually trying to say "Character not allowed in mailbox name: '\0'", but since the %c is not escaped it ends up with the truncated string.

dovecot and ntlm_auth through winbind
by Jason Gunthorpe 04 Jan '15

04 Jan '15

Hi all, I am upgrading a dovecot 1.2 installation to a 2.2 installation and have found and fixed a number of problems.. I've seen several postings in the archive about ntlm_auth not working, and it is true, there are several regressions in dovecot here. The first and simplest is that the enablement instructions in the wikki are wrong. ntlm_auth must be called as root, which is what 1.2 did. 2.2 defaults to calling it as the auth user which subtly doesn't work: Dec 30 20:30:21 quartz … [View More]

It should be: submission inet n - n - - smtpd By specifying n for chroot, it ensures that DNS lookups can occur. Otherwise, if you are using reject_unknown_recipient_domain the following error will occur: Recipient address rejected: Domain not found Hope that helps. — Dan Langille http://langille.org/

If I purposefully enter a wrong password the error becomes "pam_authenticate() failed: authentication error (password mismatch?)". So that portion is okay. Do you have any suggestions how I might find out why pam_open_session() is failing? The auth process *is* running as root. I have tried these two PAM configurations. The first one based on Maverick's /etc/pam.d/login and used to work fine on Mavericks. # dovecot: auth account password session auth optional pam_krb5.so use_kcminit auth optional pam_ntlm.so try_first_pass auth optional pam_mount.so try_first_pass auth required pam_opendirectory.so try_first_pass account required pam_nologin.so account required pam_opendirectory.so password required pam_opendirectory.so session required pam_launchd.so session required pam_uwtmp.so session optional pam_mount.so I tried to simplify it by using the one suggested on dovecot's PAM wiki. # dovecot: auth account password session auth required pam_opendirectory.so try_first_pass account required pam_nologin.so account required pam_opendirectory.so password required pam_opendirectory.so On Yosemite, neither works. Or, quite possibly, both configurations are fine and the problem lies elsewhere. Any pointers would be greatly appreciated. In the mean time I'll be using auth-passwdfile, since that works.
