[Dovecot] dovecot 0.99.14 and imaps (SSL) "hangs"
by Frode Nordahl 08 May '05

08 May '05

Hello, I just decided to try dovecot again after a long pause, and I must say that I am very impressed with the speed and resource usage, even when running with UNIX mailboxes. However, I have a problem with SSL. Every two minutes the connection is frozen, and the client has to reconnect after it times out waiting for a response from the server. My IMAP client fetches all headers, and then caches all messages in my mailboxes. However, if I do this while connected to dovecot using SSL (imaps, port 993) the connection times out roughly every two minutes, and the IMAP client must close the connection, reconnect and resume operations from where it left off. This makes resynching a 40000 message 300MB folder take VERY long :-) Using the same client, connected to the same server and syncing the same mailbox connecting to regular imap port (no TLS, port 143), everything works smoothly. The very same client, server and mailbox works flawlessly with uw-imapd and SSL. I have turned on rawlog, and everything seems to be OK. I am unable to dump the wire, because it's SSL, so not sure what to do to debug this. One thing I find a bit strange is that /var/run/dovecot/ssl-parameters.dat is a 0 byte file. Is this normal? Client: Apple Mail 1.3.11 (v622) Server: dovecot 0.99.14, installed from ports on FreeBSD 5 dovecot.conf: Regards, Frode Nordahl

[Dovecot] pop vs. imap inconsistancy
by jeff sacksteder 08 May '05

08 May '05

I am converting from courier and have noticed change in behaviour with Dovecot. I use maildirs with squirrelmail connecting by imap as well as a POP3 client. Courier would set the 'mail status-read' flag for any message which was downloaded with the POP3 interface. Dovecot apparently does not. Is this a bug or intended behaviour? If it is intentional, can it be changed with the config file?

[Dovecot] Outlook Duplicates issue is still killing me
by Jeff Ramsey 08 May '05

08 May '05

Hi, I have one pop3 client who has three computers, and he has Outlook XP on two, and 2003 on the third. They are all set to leave a copy of messages on the server, and that causes a duplicate message for every message he gets. I then can tell him to uncheck the "leave a copy on the server" box, and pop his mail, and the duplicates will go away for two or three days, only to start up again. I have a stock Fedora Core 2 server with dovecot and Sendmail. I do a nightly yum, so as to stay up2date. My version of dovecot is 1.0-test42. Has anyone else seen this issue? What can I do to fix it, short of permanently unchecking that box in Outlook? (The user is my boss, and he likes to get his email on all three computers...) -- Jeff Ramsey MIS Administrator Tubafor Mill, Inc.

[Dovecot] Compiling on Solaris 10

Trying to compile Dovecot on Solaris 10. I have tried the 99.14 release and today's 1.0-stable release.

[Dovecot] Test68 and Namespaces
by Jim Summers 08 May '05

08 May '05

Hello List, I am in the process of building a new mail system here. I am hoping to eventually migrate my users from mbox storage to maildir. They have been using mbox forever and would rather get used to maildir slowly. So I have come upon the idea of using namespaces to provide the different mailstores. Since this isn't available in the current stable, or at least I could not figure out how to do it, I have been working with 1.0-test68 since it provides the ability to configure things with the namespaces. But I am seeing an error pop up in my maillog file when exiting the client, it is: ============================================ May 3 08:11:41 tbox dovecot: IMAP(sub4000): file mbox-sync.c: line 1371 (mbox_sync_do): assertion failed: (sync_ctx->mbox->mbox_sync_dirty) May 3 08:11:41 tbox dovecot: child 12717 (imap) killed with signal 6 ============================================ Wasn't sure if it is a code bug or if it is how I have the namespace entries setup. In my dovecot.conf file I have: ------------------------------------ namespace private { separator = / inbox = yes # prefix = "#mbox/" location = mbox:~/Mail/:INBOX=/var/mail/%u } namespace private { separator = / prefix = md/ location = maildir:~/Maildir } namespace private { separator = / prefix = mail/ hidden = yes } namespace private { separator = / prefix = ~/mail/ hidden = yes } namespace private { separator = / prefix = ~%u/mail/ hidden = yes } ------------------------------------ All seems to work except the message showing up in the logs. My goal/setup is to provide: 1. mbox delivery in the mailspool(/var/mail) from sendmail 2. access to existing ~/Mail/ mbox storage. 3. ability to begin setting up / migrating to maildir in ~/Maildir Is my namespace config above overkill / borken / wrong? Ideas / suggestions on this would be greatly appreciated. Environment: Server to be: RedHat AS EL4 Clients: Thunderbird, Evolution, mutt, pine, mailreader on OS/X.

[Dovecot] test-68 coredump
by Gregory Bond 08 May '05

08 May '05

I've tried upgrading from test-51 to test-68, with mixed results. It seems to fix the problem I had with imap and Thunderbird getting confused and not showing headers or body for some email. But something in dovecot is coredumping when I select certain mailboxes. Thunderbird just hangs when you select that mailbox, and mutt gets an EOF on the imap socket while "fetching message headers". Other mailboxes seem to run OK. The failing ones _might_ be empty or have only 1 message in them. Removing index files doesn't help. There is a core file in /var/run/dovecot, and file(1) says it's from dovecot-auth, but GDB can't make sense of the core with that executable, and the login has well and truly run when the core happens. (The core doesn't seem to be from the imap process either.) Any clues how I might debug this? [Solaris 2.8, gcc-3.3, dovecot test-68, imap+Maildir, Thunderbird 1.0.2 on OSX and mutt on Solaris]

[Dovecot] quota-command?
by Marten Lehmann 08 May '05

08 May '05

Hello, if you log in at hotmail.com, gmx, lycos or yahoo, you can see something like "using 1.4mb of 250mb total". Is there any IMAP command to check to current quota usage? Our webmail-interface will not have access to the filesystem to summarize the size of each file, so an IMAP-command would be great. I don't know if this would be a new feature or just part of the Maildir++ quota-system, that is not yet supported by dovecot. Regards Marten

[Dovecot] Migrating from courier-imap to dovecot
by Odhiambo Washington 08 May '05

08 May '05

Hello Gang, I am new to dovecot and the only reason (so far) I would like to use dovecot, and in production with 12k+ users, is the fact that it's supposed to be faster and less of a resource hog. Now, sometimes I am really good at reading the documentations but it sometimes happens that one overlooks something. I did read the migration notes three times! My users are in /etc/passwd and I am running dovecot in IMAP only mode. I did put default_mail_env = maildir:~/Maildir in dovecot.conf, then for one user, I did the following: cd ~wash/Maildir cp courierimapsubscribed .subscriptions # Then I edited to remove "INBOX." cp courierimapuiddb dovecot-uidlist The permissions are right, but when I login as this user, I don't see all the folders that had been there before when he was using courier-imap!! When I login to the web interface (we use Squirrelmail) and go to the Folder options, I can't see any folders to subscribe to either! Now my questions: 1. What am I overlooking?? 2. Does someone have a script that can be used to automate the copying of courierimapsubscribed to .subscriptions and that of courierimapuiddb to dovecot-uidlist, and the editing to remove the "INBOX."? I am sure I really don't have to reinvent the wheel, no? Meanwhile I am hitting google, while waiting for your answers.

[Dovecot] How to check for keywords in IMAP store?
by Steffen Kaiser 08 May '05

08 May '05

Hello, I'm checking my way to migrate from Courier to Dovecot. Wiki says that "there's currently no easy way to migrate them [the keywords]". Frankly, I lack the information to check if some client is using keywords at all. More importantly, is it OK to assume that when SELECT INBOX returns no \* in OK [PERMANENTFLAGS ...] that the IMAP server does not allow keywords at all? [BTW: Is there a searchable mail archive of the Dovecot list?] Bye, -- Steffen Kaiser
