[Dovecot] unknown namespace with Mac OS client
by Francisco Reyes 05 Feb '07

05 Feb '07

I see in this thread, http://dovecot.org/list/dovecot/2006-April/012918.html, that others had simmilar problems with Mac OS client. Anyone got a working Dovecot + Mac OS setup? In particular with RC15. Our setup default_mail_env = maildir:Maildir namespace private { separator = . prefix = INBOX. inbox = yes } Would it help to use hidden = yes ?? Reading the description doesn't say much to me.. in particular I guess I am not familiar with the IMAP protocol to appreciate the explanation in the config file. The server is getting data originally coming from a Courier setup. I wrote a couple of scripts to convert files names and delete old setup files. So far we have moved 3 domains to this machine and the only one with the problem so far is the customer with the Mac client. Unless we can solve this soon, we will have to move him back to a courier server ... until we can figure how to solve this problem.

[Dovecot] Push IMAP
by Paul 05 Feb '07

05 Feb '07

Hearing that today's new Apple device is going to work with push IMAP from Yahoo, my first thought is to wonder whether an extension might make it possible for a Dovecot server to push its own IMAP in a compatible way. Paul

[Dovecot] command line options
by AJ Weber 05 Feb '07

05 Feb '07

Is the wiki up-to-date on the command-line arguments that can be passed to dovecot? I don't like the fact that I have to hard-code the "listen address" in the config file. Even though it shouldn't change (rarely if ever), when I have a multi-homed host, I need to specify only one of the interfaces. Would it be possible to either: 1) Make --listen into an optional, command-line argument; or 2) Make the listen config-file parameter understand interface names instead of just IP Addresses? (Like "eth0") -AJ

[Dovecot] beta8: core, signal 11
by Jeff A. Earickson 05 Feb '07

05 Feb '07

Timo, The gdb analysis is attached. It looks like memory got seriously stomped in this core dump. There was no assert or other useful information in the syslog. My setup: Solaris 9, imap and imaps, mbox format, INBOXes NFS mounted, index files on local ufs filesystem, beta8 configured like so: VERSION=1.0.beta8 CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot.$VERSION \ --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl \ --with-sql-drivers=no \ --disable-ipv6 \ > configure.out Jeff Earickson Colby College

[Dovecot] 1.0rc19 with plugins on AIX 5.2
by Ralf Becker 03 Feb '07

03 Feb '07

Hello, has anyone out there successfully build dovecot on AIX with plugins supported? I'm talking about an dlopen error when a plugin tries to access global symbols, that are defined in the dovecot "parent" binary For example: # MAIL_PLUGINS=zlib /usr/local/libexec/dovecot/imap imap(root): Error: dlopen(/usr/local/lib/dovecot/imap/lib20_zlib_plugin.so) failed: rtld: 0712-001 Symbol i_error was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_get_data was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_skip was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_seek was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_stream_close was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol i_panic was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. rtld: 0712-001 Symbol pool_get_exp_grown_size was referenced from module /usr/local/lib/dovecot/imap/lib20_zlib_plugin.so(), but a runtime definition of the symbol was not found. Additional errors occurred but are not reported. Maybe libtool is the problem, because it does not export global symbols correctly. Or would a newer version of AIX vac fix this? Any ideas? I'm using dovecot 1.0rc19, AIX 5.2-06 and vac 5.0.2 Regards, Ralf -- ______________________________________________________________________ Dipl.-Inform.

[Dovecot] Automatic Folder Expiry (plugin?)
by Troy Engel 02 Feb '07

02 Feb '07

Greetings, I'm migrating an existing Courier IMAP installation to Dovecot (1.0rc19 right now) on a new server; there's one feature I'm not sure if Dovecot supports - but it might and I'm missing it, so I'll ask. In Courier there's an option to expire a folder after a given time period; ostensibly it's to keep a Trash folder clean, but we use it to keep the Junk folder (where spam is delivered by Exim) clean. How can I do this in Dovecot? Here's the chunk from Courier for those unfamiliar with it (just part of the verbiage): ##NAME: IMAP_EMPTYTRASH:0 # # The following setting is optional, and causes messages from the given # folder to be automatically deleted after the given number of days. # IMAP_EMPTYTRASH is a comma-separated list of folder:days. # # Important: the purging is controlled by CTIME, not MTIME ... So in our case it's set like so: IMAP_EMPTYTRASH=Junk:14 Thanks for any help/ideas - I'm not sure if we can live without this feature, the amount of spam is horrendous and users never clean out that folder. -te -- Troy Engel | Systems Engineer Fluid, Inc | http://www.fluid.com

[Dovecot] Planning a dovecot deployment: issues and questions
by Dan Price 02 Feb '07

02 Feb '07

Hi folks, I am currently evaluating Dovecot for deployment to ~200 software engineers (so, heavy email users); I'm hoping this list could provide wisdom about how best to do the configuration, evaluation and deployment, and what testing folks have done to determine whether dovecot is right for their site. Below I've listed the diffs between the dovecot-example.conf and our config. I've been playing with 1.0rc19 running on Solaris Nevada. We have set it up on our server on an alternate port from the existing IMAPd, which is something ancient, horrible and problematic. We're using sendmail and mail.local as our MTA and MDA, respectively, as these ship with the OS, and we need to test them. I have some users who have volunteered to experiment with the server, and they are starting to do so. I've also seen the "flags" problems others have mentioned on the list, and I do not think I could deploy to production with that bug affecting the users. I also have some issues which I'm not sure have been previously reported: One user (of my 4 test users) is occasionally seeing a bug in which mutt 1.4.2.1 claims to be "[downloading xxx/30724]" headers. Upon getting very near to the 30724 total, the total rises to something like: "[downloading xxx/50132]". And on and on. The actual number of messages in the box is 30724. This is not very reproducible, and we do not yet know if it's a problem with mutt or dovecot. Another, using Apple's Mail.App reported: "Everything was working fine until i quit out of my mail app (Mac mail) and restarted. Then i saw weird things: - messages wouldn't get marked unread - messages from eons ago started showing up in my Drafts folder - Inbox would keep spinning/loading - then eventually Inbox just hung showing me no messages" Any thoughts about how to approach these issues? I don't really have a feel for how to go from user-observed-app-doing-X to imapd-is-doing-Y. The big challenge for our site may be mailbox size: the median mailbox size is 62M, the average is 176M and the largest is 1.1GB. I'd be curious to know what sort of mailbox sizes other sites have experienced, and how widespread the use of the Dovecot MDA is-- is this likely to make a big difference for us, and will we have to migrate our (approximately 25) procmail users to sieve? Having read the recent discussions about "1.0", I think my team would really appreciate knowing how to obtain something that was thoroughly vetted and worked highly reliably. If major changes are coming, I think it'd be great to have a 1.0.x stability focused tree, and a 1.1.x (or 2.x.x) feature tree.
