Re: [Dovecot] using dsync to convert mailboxes looses caching options

With 2.0.16 hdr.xxx fields get copied fine (but of course without timestamp). With the patch you provided they don't get copied whether using mirror or backup & starting from scratch. I'm doing a Maildir to sdbox migration otherwise don't think I'm doing anytihng strange. Mark ________________________________________ From: Mark Zealey Sent: 08 December 2011 09:35 To: Timo Sirainen Cc: Dovecot Mailing List Subject: RE: [Dovecot] using dsync to convert mailboxes looses caching options OK I'll test the header copying more fully. The reason we want to preserve caching decisions is to avoid an IO storm when users log in to their mailboxes after an sdbox upgrade so it would be great to be able to have some way to warm caches.

[Dovecot] using dsync to convert mailboxes looses caching options
by Mark Zealey 10 Dec '11

10 Dec '11

Hi there, We're trying to convert users from Maildir to sdbox at present; I'm using dsync to achieve this (2.0.16) however when the user's have been converted we only get minimal information in the caching files. Is there some way to preserve all the caching decisions that were previously made so that when the user logs in to the new mailbox we don't have to cause an io storm rebuilding the cache that we know was good? Dovecot seems to be partially doing this - if i remove the logs/cache from the source mailbox no cache files are built in the conversion; if i put them back then we get a cache file built but it only contains a few bits of information (guid, date.save). Looking into this a bit further i find that when the caches are present at source the fields are preserved but the 'last used' date and caching decisions are not which I suspect means dsync doesn't bother caching on import - only fields with a yes decision in the source are copied (but their decision is only copied as a tmp with the date of import). For example: Source idxview cache: -- Cache fields -- # Name Type Size Dec Last used 0: flags bit 4 tmp 2011-11-25 16:09 1: date.received fix 4 yes 2011-11-26 16:17 2: size.virtual fix 8 tmp 2011-11-25 16:09 3: imap.bodystructure str - tmp 2011-11-25 16:09 4: mime.parts var - tmp 2011-11-25 16:09 5: hdr.IMPORTANCE hdr - tmp 2011-11-25 16:09 6: hdr.X-PRIORITY hdr - tmp 2011-11-25 16:09 7: hdr.CONTENT-TYPE hdr - tmp 2011-11-25 16:09 ... 18: date.sent fix 8 no 1970-01-01 01:00 19: date.save fix 4 yes 2011-11-26 16:17 20: size.physical fix 8 no 1970-01-01 01:00 21: imap.body str - no 1970-01-01 01:00 ...

[Dovecot] POP - preventing re-download with server move
by Trutwin, Joshua 10 Dec '11

10 Dec '11

Hi, Curious if anyone has any good suggestions to handle this. I try to get my hosting users to use IMAP but most use Outhouse and the IMAP support is somewhat annoying for many so I typically have them change their settings when using POP to leave copies on the server. That way when they get the inevitable virus or wanna use webmail they have a backup copy and webmail sees their saved mail. So now I have to move my sites to a new server and I'm trying to avoid having all these messages re-downloaded by POP clients. Some of the sites I've moved with low email usage have just dealt with the re-download and cleaned up afterwards. I have a few other accounts though that I'm more concerned about that have massive amounts of stored email. The mail is stored in Maildirs - a sample file: 1280409166.23580.foo:2,S If I move this to server "bar" would renaming the file to 1280409166.23580.bar:2,S prevent this somehow? Old server uses qmail-pop, new server uses dovecot 2.0. Thanks for any tips, Josh

[Dovecot] noaclright
by Knud Dombrowsky 10 Dec '11

10 Dec '11

Hi, I recently upgraded to openSuse 12.1 which comes with dovecot 2.0.14. Because of mail-client-problems I am running one dovecot which requires authentication via a client-certificate and another one which can be used without a certificate. (Configurations can be found below.) Since the upgrade our shared mailbox is no longer visible. I tried to repair this by setting the ACLs once again (using imap-acl in Thunderbird) but every time I try to set a new ACL the tool says "noaclright" and dovecot logs the following messages: Dec 7 14:31:14 mailbox dovecot: imap(<sharing-user>): Error: fstat(/home/<sharing-user>/Maildir/.<shared-folder>/dovecot-acl.lock) failed: No such file or directory Dec 7 14:31:14 mailbox dovecot: imap(<sharing-user>): Error: file_dotlock_open(/home/<sharing-user>/Maildir/.<shared-folder>/dovecot-acl) failed: No such file or directory Needless to say the file exists and its contents looks like it should. (Every line is an ACL like "user=testuser ilrws") I took a look at the changelog from 2.0.14 onwards and since it says nothing about my problem I am not looking forward to compiling dovecot myself and installing it. Any ideas why this is happening? Is this a known problem?

[Dovecot] overriding userdb connection host for doveadm-user
by Micah Anderson 10 Dec '11

10 Dec '11

I've got my users in a replicated database setup and dovecot configured with two connect lines in dovecot-sql.conf: connect = host=127.0.0.1 port=3306 dbname=users user=user password=pass connect = host=127.0.0.2 port=3306 dbname=users user=user password=pass this works really well to help balance the load. However, when a new user is created, the replication information sometimes has not made it to the slave database before my user creation process tries to send that new user an email about their new email account. If it hasn't and the email gets sent, then it bounces because postfix thinks the user doesn't exist yet. Replication usually happens within seconds, but could be delayed due to problems. I would like a way to see if the new user's information has been replicated yet before sending the email. I was thinking I could use 'doveadm user' to lookup the user, but I am not sure that I can specify one of the specific 'connect' lines in my configuration to check. Is there a way to override that configuration variable to do this test? I tried various incarnations of passing '-o connect=host='... but doveadm user would just ignore them. thanks for any suggestions! micah ps - yes, I can make my user creation process just 'sleep' for an arbitrary amount of time and by that time the replication should have occured, but that is a bit of a shot in the dark, and doesn't handle longer replication delays that could potentially happen. --

[Dovecot] Make entire mailbox read-only (ACLs?)
by David Jonas 10 Dec '11

10 Dec '11

Hello, Is there a way of locking a mailbox, effectively making it read-only to IMAP clients? I've read through http://wiki2.dovecot.org/ACL. I created dovecot-acl with the content "owner lr" in .INBOX which seems to keep me from copying messages into the folder, but not out. I have the plugin configured correctly, it seems, since MYRIGHTS command shows the correct value: 30 MYRIGHTS "INBOX" * MYRIGHTS "INBOX" lr Am I barking up the wrong tree? Is there an easier way to lock a mailbox? post-login scripting perhaps? Thanks!

[Dovecot] Major bug with hardlinks and lmtp
by Brad Schuetz 10 Dec '11

10 Dec '11

In working on trying to fix the crash issue from my last email I had enabled LMTP delivery to try it out instead of using the LDA. I have discovered that when a single piece of email is to be delivered to multiple users the message is being hard linked instead of copied into each mail box. This is a major problem that makes LMTP unusable in an environment where each mailbox has it's own UID since the hard linked file will only be readable by one of the users. I assume this is related to "maildir_copy_with_hardlinks=yes", however this setting doesn't say anything about hardlinking across different email accounts. -- Brad Schuetz
