[Dovecot] assertion failed: (conn->refcount > 1)

Hi, Sometimes (happens maybe twice in a day), I have the following errors: Dec 15 16:10:17 dovecot: auth(default): file auth-client-connection.c: line 33 (auth_client_send): assertion failed: (conn->refcount > 1) Dec 15 16:10:17 dovecot: child 17152 (auth) killed with signal 6 Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dec 15 16:10:17 dovecot: imap-login: Can't connect to auth server at default: Connection refused Dovecot seems to recover though, because afterwards it still works. I did however notice that the logging-in seemed to hang for a while (some seconds).

[Dovecot] How to serve two "inboxes" via imap
by Roderick Johnstone 15 Dec '05

15 Dec '05

Hi In our setup we have mail delivered to /var/spool/mail/<username>. Many users like thunderbird as their MUA and we typically have thunderbird set up to read mail using a movemail account with the local mail directory set to ~/mail so that the mail can be read easily by pine as well. So, when a user clicks the "Get Mail" button in Thunderbird, mail is moved from /var/spool/mail/<username> to ~/mail/Inbox. Although I can serve other folders from ~/mail my imap clients don't see ~/mail/Inbox, they see just /var/spool/mail/<username> as INBOX. Can anyone advise please how to make the ~/mail/Inbox available as well via imap using dovecot (currently using 1.0-alpha5). We currently use default_mail_env = mbox:~/mail/:INBOX=/var/spool/mail/%u Many thanks Roderick Johnstone

[Dovecot] Compiling 1.0alpha5 on Mac OS X 10.4 Server
by Roger Weeks 14 Dec '05

14 Dec '05

I am trying to compile the 1.0alpha5 on Mac OS X Server 10.4.3, and not having success. My configure flags are: ./configure --with-mysql We're thinking of migrating from courier. The configure processes okay, but I get this error a ways through the make: /usr/bin/ld: multiple definitions of symbol _sha1_result ../lib/liblib.a(sha1.o) definition of _sha1_result in section (__TEXT,__text) /usr/lib/mysql/libmysqlclient.a(sha1.o) definition of _sha1_result in section (__TEXT,__text) collect2: ld returned 1 exit status make[3]: *** [dovecot-auth] Error 1 make[2]: *** [all-recursive] Error 1 make[1]: *** [all-recursive] Error 1 make: *** [all] Error 2 Has anyone seen this error compiling? I'm not sure how to get around it. -- Roger J. Weeks Systems & Network Administrator Mendocino Community Network

[Dovecot] checkpassword authentication
by Florian Füessl 14 Dec '05

14 Dec '05

Hi, does anyone already use the checkpassword authentication scheme? I have not found any description how I have to configure dovecot in order to work together with qmails checkpassword. Enabling passdb = checkpassword /bin/checkpassword in dovecot.conf starts /bin/checkpassword for every authentication request, but the result does not seem to matter for the authentication. Without enabling a userdb entry, dovecot claims not to be able to find out the uid, gid and home of the user, although checkpassword replies these values. Setting static values with "userdb = static uid=$fixed_mail_uid gid=$fixed_mail_gid home=/maildata/%d/%n" results in being every login successful, no matter if the checkpassword authentication is ok, or not. I'm using the latest dovecot nightly build from 22. Nov. 2005. - Florian

[Dovecot] inotify.h not found
by Mark Rosenstand 14 Dec '05

14 Dec '05

Hi, dovecot (1.0.alpha5) won't compile with inotify support because inotify.h can't be found. I'm running Linux 2.6.15-rc5 with headers from 2.6.12 (like most vendors). I've noticed that beagle and other inotify-enabled applications ships with an inotify.h. Could this be scheduled for alpha6? :-)

One of the mbox files on my server causes dovecot to assert. I've caught the assert in gdb and have attached the backtrace.

[Dovecot] No "Ok Dovecot Ready " on fc3 with ssl on ports 993 and 995
by ankush grover 14 Dec '05

14 Dec '05

hey friends, I am trying to secure my mail server on FC3.I have enabled TLS support in postfix(version postfix-2.1.5) and want to use ssl settings for dovecot( 0.99.13). Lines of ssl in /etc/dovecot.conf protocols = imaps pop3s imaps_listen = * pop3s_listen = * ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat disable_plaintext_auth = yes If i do telnet localhost 993 or 995 I don't see any "Ok Dovecot Ready" message.If I enable pop3 and imap in dovecot.conf and then I telnet localhost 110 or 143 I can see "Ok Dovecot Ready" message. Any pointers what else I am missing for ssl in dovecot and I am also attaching the dovecot.conf file with this email. Thanks & Regards Ankush Grover
