[Dovecot] E-mail marked as unread
by Andy Cravens 17 Oct '05

17 Oct '05

I have a problem where an e-mail will be marked as unread even though it has been read. When I click on the message the status changes to "read" however, when I go to check for new mail the status changes back to "unread." If I move the message to the trash folder and then move it back to my inbox, the problems stops. Unfortunately, a different e-mail is affected by this problem a few minutes later. I'm using alpha 3 on Solaris 9 and my client is Mozilla 1.7.7 on Solaris 9. No messages in the log to indicate a problem. Anybody else seen this?

[Dovecot] Invalid Headers
by Brant Fitzsimmons 16 Oct '05

16 Oct '05

Hello all, I have been trying to compare Dovecot to Cyrus and in trying to to migrate some mail from Dovecot to Cyrus I am unable to do so because of an invalid header. The From header is incorrectly written as From> as opposed to the correct From: . Any idea what may be causing this and how to fix it? My setup is Fetchmail->Postfix->amavis-new->clamav->dovecot for dovecot and Fetchmail->Postfix->amavis-new->clamav->cyrus for cyrus. When receiving mail in the cyrus setup I don't have the problem. Any thoughts? -- Brant Fitzsimmons brant(a)bfcomputerconsulting.com ------------------------------------------------------------------- "Strange times are these in which we live when the old and the young are taught falsehoods in the schools of learning.

[Dovecot] A Couple Of Issues (APOP Causes Auth SIGSEGV, Umask Setting Ineffective)
by Sabahattin Gucukoglu 16 Oct '05

16 Oct '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm very happy with Dovecot and wish the best for its continued development. It's a true testament to brilliant componentised design and Unix philosophy. Configuration made easy because of the way the file is parsed and a single point of startup make it ridiculously straightforward (and lovely) to administer. But of course, we all already know this ... I'm sorry that I can't provide traces at the moment, I'm working from an optimised set of binaries. (-O3 -march=i586 -fomit-frame-pointer) GCC 3.4.4, Gentoo X86 2005.0, Linux 2.6.13, Glibc 2.6.5. Pegasus Mail 4.30B1 is the client on Win32. Dovecot is still Alpha2 (I will upgrade when Gentoo has updated their ebuild). Of course if you advise I'll look at rebuilding newer versions or patched versions with(out) debug symbols. 1. When I attempt APOP login of any variety on the POP3 server auth dies with signal 11. passwd-file is of course listed as a password database, alongside shadow. I get back "-ERR Internal authentication failure - please try again later." or something like this and all subsequent authentication in that session won't work (of course, auth is dead). The password entry is in /etc/dovecot.secrets (perms=0700,uid=0,gid=0) and looks like: username:{PLAIN}cleartextpassword 2. Umask setting gone strange. I set it, per example comment, to "7077" rather than default of 0077 (just to be precise...). When directories are subsequently created, user owning it doesn't even get read/write permissions (just x) and group gets rw but not x! It has not even to do with my system umask (022) set by login. I've set it to 0000 for now in dovecot (/etc/skel has .mail put in people's homedirs with 0700, so there's no worry, but of course I'd like to see that one fixed). If you need more info please let me know. Hope this is enough. Cheers, Sabahattin - -- If an email tells you to forward it to all your friends, please temporarily forget that I am your friend.

[Dovecot] Dovecot doesn' compile with gnutls

Hi all, tried to build dovecot-1.0.alpha3 with gnutls. The build stops something like: ssl-proxy-gnutls.c:420: warning: 'gnutls_dh_params_set' is \ deprecated (declared at /usr/include/gnutls/compat8.h:82) ssl-proxy-gnutls.c: In function 'read_rsa_parameters': \ ssl-proxy-gnutls.c:446: warning: 'gnutls_rsa_params_set' is \ deprecated (declared at /usr/include/gnutls/compat8.h:77) make[4]: *** [ssl-proxy-gnutls.o] Error 1 Building with openssl 0.9.8 there are connection errors: dovecot: Oct 15 22:46:48 Error: imap-login: Can't load certificate \ file /etc/ssl/certs/dovecot.pem: error:25066067:DSO support \ routines:DLFCN_LOAD:could not load the shared library Any hints? Please notice I prefer gnutls ;-) Thanks Elimar -- On the keyboard of life you have always to keep a finger at the escape key;-)

[Dovecot] ssl + dovecot + debian sid
by Novák Áron 16 Oct '05

16 Oct '05

Hi! On the unstable version of Debian I try to use Dovecot POP3-ssl server. I both tried out the debian package(1.0.alpha3-2.0.1) from the official repository and compiling from source(1.0 alpha3 version). The error is always the same: Oct 15 09:28:04 www dovecot: pop3-login: Can't set cipher list to 'all:! LOW': error:25066067:DSO support routines:DLFCN_LOAD:could not load the shared library Is it a bug of dovecot or a bug of the openssl package? My relevant libssl packages: Package: libssl0.9.8 State: installed Version: 0.9.8-3 ------- Package: libssl0.9.7 State: installed Version: 0.9.7g-5 Thanks: Aron Novak

[Dovecot] a few questions about my experience with alpha1
by Glenn Leavell 16 Oct '05

16 Oct '05

Hi all, I've just switched from 0.99.10.6 to alpha1 on a Solaris 9 system, and I have a few questions: 1) I'm using "verbose_proctitle = yes" but I don't see the special username or IP address information in the output of ps. I've used: ps -fu dovecot ps -ef | grep dovecot /usr/ucb/ps aux | grep dovecot The process table simply shows the /usr/local/sbin/dovecot, dovecot-auth, and imap-login processes. Is there something else that I need to do, or is there a special way that I should use ps? 2) After sending dovecot a HUP signal, the logs will report something like: Warning: SIGHUP received - reloading configuration And everything seems to work fine. However, *sometimes* after sending a HUP signal, logging will stop indefinitely. Has anyone else noticed anything similar? 3) We use UW in production, and I'm new to any real use of namespaces. Almost all of our clients use the root "~/Mail/" to find their folders (in $HOME/Mail/) and their INBOXes are located in $HOME/.inbox. A few people actually find their folders with the direct path Mail/foldername. So, I'm trying to configure Dovecot to work with any of these roots / prefixes: ~/Mail/ Mail/ "" (empty/blank) I'm using the namespace configuration below, and it seems to work with any of the above prefixes. However, the logging that I see makes me wonder if I'm doing it the best way. Note the attached log file. All of this output was generated with this single IMAP command: A01 LOGIN bozo mypassword Here's my configuration: **************************************************************************** # Default namespace private { separator = / prefix = location = mbox:%h/Mail/:INBOX=%h/.inbox:INDEX=%h/Mail/ inbox = yes hidden = no } # This is the standard ~/Mail/ namespace that our clients tend to use namespace private { separator = / prefix = ~/Mail/ location = mbox:%h/Mail/ hidden = yes } # This namespace is for a few folks who might actually try to # directly access "Mail/foldername" -- as if they were accessing a real # filesystem path. namespace private { separator = / prefix = Mail/ location = mbox:%h/Mail/ hidden = yes } **************************************************************************** So, is this the best way to configure the namespaces for what I'm trying to accomplish? And any pointers on how to interpret what Dovecot is working through with regard to the attached logs would be appreciated. Notice the "Sending log messages too fast, throttling.." message (again, generated from that single login command). What might be causing that? By the way, is there any real difference between the use of %h/Mail and the possible use of ~/Mail in the location fields above?

[Dovecot] Problem with pop3 and alpha3
by aspar＠unisa.it 16 Oct '05

16 Oct '05

Hi all, I have a problem with dovecot-alpha3 and pop3 protocol (on a tru64 5.1a...) In my Maildir/cur there are 8144 mails and if I use pop3 protocol I receive in the output 8146 line instead of 8144. The problem is that 2 mails are duplicated . The output of List command is like: 1 51265 2 261783 . . . 2987 30291 2987 30291 (duplicated line) 2988 16631 . 4601 1231 4602 8921 4602 8921 (Another duplicated line) 4603 1313 I've deleted dovecot.* and dovecot-uidlist in the Maildir path but the problem remains. Suggest? Is a bug? I've tried also to remove the first 1000 messages but the problem now is on the mail number 2635 and not 1987 like I can think.

[Dovecot] Possible bug: why is the owner of home-directory important?
by Qweb - Yavuz Aydin 16 Oct '05

16 Oct '05

Dear all, I am trying to migrate one of our systems to dovecot. We were using uw-imapd in black-box-mode before. Since the home-directory of a user is not unique per definition on our systems, we have kind of a different setup. As an example: I got a user, let's say user1. It's home directory is /local/web/websites/5850844095/www. This directory has the following permissions: # ls -la /local/web/websites/5850844095/|grep www drwxr-x--- 7 www-data g5850844095 4096 Oct 13 12:28 www (user1 is member of the group g5850844095) Why is logging in not working properly? See: # telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. 1 LOGIN user1 password 1 OK Logged in. Connection closed by foreign host. And in the logfile I see: Oct 13 13:09:47 s1 dovecot: chdir(/local/web/websites/5850844095/www) failed with uid 1020: Permission denied Oct 13 13:09:47 s1 dovecot: child 1527 (imap) returned error 89 However, when I change the permissions on the home-dir to 755, it works. The point is, none of my mailboxes (INBOX or others) are in my home-dir, so why does dovecot need my home-directory? I hope someone can help. PS1 the default_mail_env reads: default_mail_env = mbox:/local/mail/imap/%u/:INBOX=/local/mail/spool/%u PS2 This is on a Debian Sarge (3.1) system. -- Best regards, Yavuz Aydin Qweb Internet Services
