Include IMAP Junk folder to pop3 clients.

Hi, I would like to include all new mails of Junk box (I have a global sieve filtering set) folder to pop3 clients. Is this possible? This is my current configuration. # 2.2.25 (7be1766): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.15 (97b3da0) # OS: FreeBSD 9.3-RELEASE-p43 amd64 auth_default_realm = example.com auth_failure_delay = 30 secs auth_mechanisms = plain login disable_plaintext_auth = no info_log_path = /var/log/dovmaillog lmtp_rcpt_check_quota = yes log_path = /var/log/dovmessages login_greeting = NO UBE/UCE - Trespassers will be pursued. mail_gid = mail mail_home = /home/vmail/%d/%u mail_max_userip_connections = 30 mail_uid = vmail mailbox_list_index = yes managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext namespace inbox { inbox = yes location = mailbox Archive { auto = create special_use = \Archive } mailbox Drafts { auto = create special_use = \Drafts } mailbox Junk { auto = create special_use = \Junk } mailbox Sent { auto = create special_use = \Sent } mailbox Trash { auto = create autoexpunge = 30 days special_use = \Trash } prefix = } passdb { args = /usr/local/etc/dovecot/local.ext driver = sql } plugin { antispam_backend = dspam antispam_dspam_args = --deliver=;--source=error;--signature=%%s;--user;%u antispam_dspam_binary = /usr/local/bin/dspam antispam_dspam_result_header = X-DSPAM-Result antispam_signature = X-DSPAM-Signature antispam_signature_missing = move antispam_spam = Junk antispam_trash = Trash quota = maildir sieve = /home/vmail/.sieve/%d/%u/.user.sieve sieve_dir = /home/vmail/.sieve/%d/%u/.sieve sieve_global_dir = /home/vmail/.sieve/global sieve_global_path = /home/vmail/.sieve/global.sieve sieve_max_script_size = 512K } protocols = imap pop3 lmtp sieve sendmail_path = /usr/local/sbin/sendmail service auth { unix_listener /var/spool/postfix/private/dovauth { group = wheel mode = 0666 user = postfix } } service imap-login { chroot = login client_limit = 256 executable = /usr/local/libexec/dovecot/imap-login inet_listener imap { address = * port = 143 } inet_listener imaps { address = * port = 993 } process_limit = 128 process_min_avail = 2 service_count = 1 } service imap { executable = /usr/local/libexec/dovecot/imap } service lmtp { unix_listener /var/spool/postfix/private/dovlmtp { group = wheel mode = 0666 user = postfix } } service managesieve-login { inet_listener sieve { port = 4190 } } service pop3-login { chroot = login client_limit = 256 executable = /usr/local/libexec/dovecot/pop3-login inet_listener pop3 { address = * port = 110 } inet_listener pop3s { address = * port = 995 } process_limit = 128 process_min_avail = 2 service_count = 1 } service pop3 { executable = /usr/local/libexec/dovecot/pop3 } ssl_cert = </etc/ssl/certs/server.pem ssl_key = </etc/ssl/private/server.pem userdb { driver = prefetch } userdb { args = /usr/local/etc/dovecot/local.ext driver = sql } protocol lmtp { mail_plugins = quota mail_log notify sieve quota } protocol lda { auth_socket_path = /var/spool/postfix/private/dovauth mail_plugins = quota mail_log notify sieve quota } protocol sieve { mail_max_userip_connections = 10 managesieve_implementation_string = Dovecot Pigeonhole managesieve_logout_format = bytes=%i/%o managesieve_max_compile_errors = 5 managesieve_max_line_length = 65536 } protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_max_line_length = 64 k mail_plugins = quota mail_log notify imap_quota antispam } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_uidl_format = %08Xu%08Xv }

Moving Maildir folders
by Mark Foley 18 Jul '16

18 Jul '16

Our office had a user leave. Another user is taking over her duties and needs reference to the departing user's email. I've copied that entire departed user's Maildir structure to the current user: mv olduser/Maildir/.* curuser/Maildir/.olduser I did change permission and ownership on curuser/Maildir/.olduser to be the target user. I did not bring over the olduser/Maildir/dovecot* files (indexes, subscriptions, etc.) as I thought that would be bad. Nevertheless, the curuser cannot see this new olduser folder (which should be at the same level as Inbox, Junk Mail, etc.). I did manually add olduser to the curuser/Maildir/subscriptions file, but still nothing. So, what did I do wrong and how do I fix it? THX -- Mark

doveconf -n display error for "remote"
by Michael Fox 16 Jul '16

16 Jul '16

Upon further testing, it seems that the issue below may only be a display bug in doveconf. In other words, the remote filter appears to work as configured, even though it is displayed with duplicate prefix length by doveconf. Is this sufficient information to report a bug or is there some other protocol? Michael ------------------------------------------- Dovecot --version: 2.2.9 I configured the following in local.conf: remote 192.168.7.128/27 { ssl = no } remote 192.168.7.0/24 { ssl = yes } But, when I run doveconf -n, I see: remote 192.168.7.0/24/24 { ssl = yes } remote 192.168.7.128/27/27 { ssl = no } Note the repeated network prefix length (/27/27 and /24/24).

controlling STARTTLS by IP address
by Michael Fox 16 Jul '16

16 Jul '16

On my POP3 server, I need to be able to control the use of STARTTLS by client IP address. Specifically: * Clients on certain internal subnets (e.g., 192.168.1.0/24) must not have the option to use TLS. If the client tries to use STARTTLS, the option should be rejected. This is to satisfy US FCC rules regarding the use of encryption over certain radio frequencies. * All other internal clients (e.g., 192.168.0.0/16, but not 192.168.1.0/24) should be able to use STARTTLS if they choose to. * All external clients (0.0.0.0/0) will be required to use TLS. Is there a way to control which clients are allowed to use STARTTLS according to the client's IP address? Thanks, Michael

by Zhang Huangbin 15 Jul '16

15 Jul '16

Dear all, I got error "authentication failed: Connection lost to authentication server", i turned on debug mode in Postfix/Dovecot, but this is the error i can get. All other errors point to sasl auth failure, what does "connection lost to authentication server" means? How can i exactly know what the problem is and how to fix it? Here's my Dovecot/Postfix configuration, with Active Directory integration. - dovecot.conf: http://pastebin.com/7T05kvmH - dovecot-ldap.conf: http://pastebin.com/DtkAg01v - Postfix main.cf: http://pastebin.com/Z9Wihmvr Dovecot/Postfix and AD are running in the same network (192.168.10.X), no firewall between them. Thanks for your help. :)

"Error: nfs_flush_file_handle_cache_dir: rmdir(/inboxes)" log spikes
by Joseph Tam 15 Jul '16

15 Jul '16

I received a bunch of these log messages at a rate of a few thousand per hour for one of my users -- she may have max'd out her quota. The directory is a NFS directory containing mbox formatted INBOX's. Other than alleviating the space crunch, is there any particular action I need to take? Joseph Tam <jtam.home(a)gmail.com>

quota config - when is the warning messag send?
by Götz Reinicke - IT Koordinator 14 Jul '16

14 Jul '16

Hi, we run dovecot 2.2.24 and from what I see, quota management with warning message is configured currently with "noenforcing". Our individual quota limit is stored in the users ldap DN which is fetched as I see from the logs and by "doveadm quota get -u" I tried to trigger the warning mail by going over the limit on my account step by step and can see that values are counted with the command above and in thunderbird by showing the orange and than red warning symbol at the bottom for me. But the warning mail script is not triggert. How may I debug this? from 90-quota.conf: service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail # dovecot unix_listener quota-warning { user = vmail } } /usr/local/bin/quota-warning.sh is owned currently by vmail and executable by vmail. Thanks for feedback and suggestion . /Götz
