I have followed the instructions about bug reports /generating cores located at http://dovecot.org/bugreport.html .

[Dovecot] Rejected mails

I'm getting closer, now with SMTP permitted to whole of Internet to connect to my SMTP/postfix server & for my postfix server to connect out to public Internet on tcp 25 as well. I send emails from permitted domain's SMTP servers with "Receipt Acknowledgemt" & the ack returned said it was delivered but somehow there's no mail in the mailbox & using the site below to test, it gave Rejected : http://legacy.zoneedit.com/whois.html OK, connected to gate1.mds.com.sg... < 220 gate1.mds.com.sg ESMTP > HELO edit.dnsvr.com < 250 gate1.mds.com.sg > MAIL FROM:<sender_id(a)mds.com.sg> < 250 sender <sender_id(a)mds.com.sg> ok > RCPT TO:<recipient_id(a)myportaltech.com> < 550 #5.1.0 Address rejected. The recipient_id is basically a Linux OS id in my SMTP server.

[Dovecot] Sharing mails with other users without copying data
by Ernesto Revilla Derksen 22 Feb '11

22 Feb '11

Hello. We would like to share mails without copying the data to another mailbox. The problem is that we use exim4 for delivery and maildir++ format. Would it be feasible to create a symlink or hardlink using the COPY or COPYlike (extension) command? Regards. Erny Ernesto Revilla Yaco Sistemas +34 954 500 057

[Dovecot] [Q] A mix-up between /%d/%u/ and /%d/%n for virtual users
by J4K 22 Feb '11

22 Feb '11

Hi there, I have noticed I misconfigured a dovect 1.2.n server with virtual email. Mistakingly, I used /%d/%u/ for mail_location, but /%d/%n userdb: mail_location: maildir:/var/vmail/%d/%u/ userdb: driver: static args: uid=5000 gid=5000 home=/var/vmail/%d/%n allow_all_users=yes As a result I have maildirs being created for both (e.g): /var/vmail/bigdomain.com/dirk(a)bigdomain.com /var/vmail/bigdomain.com/dirk The actual email is placed in /var/vmail/bigdomain.com/dirk(a)bigdomain.com, which I am happy with. I would liek to tidy up the configuration so that these extra maildirs are not created, without breaking everything. Would someone recommend what the best steps are? (other than reinstalling and starting from scratch - Its in production).

[Dovecot] need help with public namespaces
by Pierfrancesco Caci 22 Feb '11

22 Feb '11

Hello, I need some guidance with setting up a public namespace with per-user \Seen flags. What I want to do is that a group of users access the public namespaces and if user A reads a message, user B should still see it as new until he reads it himself. This is not happening now, and I can't figure out why. Here's the config: # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-28-server x86_64 Ubuntu 10.04.2 LTS ext3 log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps managesieve listen(default): *

[Dovecot] imap-login ESTABLISHED client sessions not timed out by server
by J4K 22 Feb '11

22 Feb '11

Good morning everyone, I noticed some mobile client connections that I know should have timed out at least 20 mins ago, yet these are still there. The device in question lost its 3G connection and never re-established it. I know, because in this case it was my 'phone ;) Why should the imap-login keep the copnnection in in EST, when it was dropped ages ago. I imagine that the mobile client did not correctly close down the session, but it should have timed out on the server. Any ideas? Has anyone noticed this afore? imap-logi 7819 dovecot 10u IPv4 24069447 0t0 TCP logout.klunky.co.uk:imaps->m83-178-105-240.cust.tele2.nl:39042 (ESTABLISHED) imap-logi 7820 dovecot 10u IPv4 24069443 0t0 TCP logout.klunky.co.uk:imaps->m83-178-105-240.cust.tele2.nl:52696 (ESTABLISHED) imap-logi 7821 dovecot 10u IPv4 24069536 0t0 TCP logout.klunky.co.uk:imaps->m83-178-105-240.cust.tele2.nl:55341 (ESTABLISHED) imap-logi 7822 dovecot 10u IPv4 24069464 0t0 TCP logout.klunky.co.uk:imaps->m83-178-105-240.cust.tele2.nl:44647 (ESTABLISHED) Linux fred 2.6.32-cgmemcap-smack #1 SMP Tue Dec 28 14:28:18 CET 2010 x86_64 GNU/Linux Debian Squeeze.

[Dovecot] Problem with ldap / quotas
by Nikolaos Milas 22 Feb '11

22 Feb '11

Hi, I am trying to enable per user quotas, but I get the following error: Feb 18 23:59:20 vmail dovecot: auth(default): ldap(tester,10.10.100.150): ldap_search((uid=tester)) failed: No such object It seems as if ldapsearch for username/password won't work with my new settings, but I can't find why. I run Dovecot v1.2.11 on CentOS 5.5. I changed my working dovecot.conf (see later) with the following changes (I used the roomNumber attribute to store the quota value): 1. Added in main part: mail_uid = 500 mail_gid = 500 2. Changed userdb with: userdb ldap { args = /etc/dovecot-usrdb-ldap.conf } and /etc/dovecot-usrdb-ldap.conf is: hosts = localhost tls = no base = ou=people, dc=example, dc=com scope = subtree ldap_version = 3 auth_bind = yes user_filter = (uid=%u) pass_filter = (uid=%u) pass_attrs = uid=user,userPassword=password auth_bind_userdn = uid=%u,ou=people,dc=example,dc=com user_attrs = roomNumber=quota_rule=*:bytes=%$,uid=home=/home/vmail/%u 3. Changed passdb with passdb ldap { args = /etc/dovecot-passdb-ldap.conf } where /etc/dovecot-passdb-ldap.conf is identical to dovecot-usrdb-ldap.conf. What am I doing wrong? Please advise. Thanks in advance, Nick My working dovecot.conf is: protocols = imap imaps pop3 pop3s disable_plaintext_auth = no syslog_facility = local1 ssl = yes ssl_cert_file = /etc/pki/CA/certs/cert-180.pem ssl_key_file = /etc/pki/CA/private/key.pem ssl_ca_file = /etc/pki/CA/certs/cert-180.pem ssl_verify_client_cert = no verbose_ssl = no login_process_size = 64 mail_location = maildir:~/Maildir/ mail_debug = no protocol imap { mail_plugins = quota imap_quota imap_client_workarounds = delay-newmail outlook-idle netscape-eoh } protocol pop3 { pop3_uidl_format = %08Xu%08Xv mail_max_userip_connections = 3 mail_plugins = quota pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol managesieve { } protocol lda { postmaster_address = postmaster(a)example.com mail_plugins = quota } auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_username_format = %Lu auth_verbose = yes auth_debug = no auth default { mechanisms = plain login passdb ldap { args = /etc/dovecot-ldap.conf } userdb static { args = uid=500 gid=500 home=/home/vmail/%u } user = root socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } } } dict { } plugin { quota = maildir:User quota # Quota limit is 4GB quota_rule = *:storage=4G # We add 100Mb more for Trash quota_rule2 = Trash:storage=100M # We set up warnings at 75% and 90% quota_warning = storage=75%% /opt/mail.sh 75 %u quota_warning2 = storage=90%% /opt/mail.sh 90 %u } and dovecot-ldap.conf is: hosts = localhost tls = no base = ou=people, dc=example, dc=com scope = subtree ldap_version = 3 auth_bind = yes pass_attrs = uid=user,userPassword=password auth_bind_userdn = uid=%u,ou=people,dc=example,dc=com pass_filter = (uid=%u) Finally, for reference (dovecot -n): # 1.2.11: /etc/dovecot.conf # OS: Linux 2.6.18-194.32.1.el5 x86_64 CentOS release 5.5 (Final) syslog_facility: local1 ssl_ca_file: /etc/pki/CA/certs/cert-180.pem ssl_cert_file: /etc/pki/CA/certs/cert-180.pem ssl_key_file: /etc/pki/CA/private/key.pem login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login mail_max_userip_connections(default): 10 mail_max_userip_connections(imap): 10 mail_max_userip_connections(pop3): 3 mail_location: maildir:~/Maildir/ mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib64/dovecot/imap mail_plugin_dir(imap): /usr/lib64/dovecot/imap mail_plugin_dir(pop3): /usr/lib64/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh lda: postmaster_address: postmaster(a)example.com mail_plugins: quota auth default: mechanisms: plain login username_format: %Lu verbose: yes passdb: driver: ldap args: /etc/dovecot-ldap.conf userdb: driver: static args: uid=500 gid=500 home=/home/vmail/%u socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix plugin: quota: maildir:User quota quota_rule: *:storage=4G quota_rule2: Trash:storage=100M quota_warning: storage=75%% /opt/mail.sh 75 %u quota_warning2: storage=90%% /opt/mail.sh 90 %u

[Dovecot] Dovecot doesn't show any e-mails, while there are a lot in the maildir
by Attila Nagy 22 Feb '11

22 Feb '11

Hi, I've recently seen the following issue. A user logs in with pop3, and sees zero e-mails. The maildir contains emails both in cur and new. The mail delivery is done with qmail, and this user have had no logins before, so it has only the inbox, trash and sent (while dovecot is configured to create drafts and spam folders too). Because of this, the user doesn't have any dovecot indexes either. So, he logs in, and sees nothing. The strange thing is Dovecot doesn't create any of the above directories nor indexes. After moving the mailbox to another server, the user can log in, the additional folders get created and also the indexes appear. pop3 shows the correct amount of emails. Moving the mailbox back to the original server shows the same issue: no emails at all. Restarting dovecot on the original server resolves the issue. This is a pretty loaded machine, so I couldn't trace the processes. I know that this isn't too much, but that's what I have. The only thing I could identify in the error log is: Feb 17 12:45:58 pop3(varszr@asdfg): Warning: Created dotlock file's timestamp is different than current time (1297943148 vs 1297943086): /home/varszr@asdfg/Maildir/subscriptions Which may happened due to a restart and maybe a clock setting. But that was yesterday.
