Sendmail Dovecot Trouble
by John Rowan 14 Jul '18

14 Jul '18

I've been struggling trying to get Thunderbird to read e-mail off a CentOS 7 server. Sendmail writes mail in /var/spool/mail I've configured dovecot to try to read from there using Thunderbird (POP3/SMTP). The firewall allows ports 25/110. I verified I have mail in /var/spool/mail but Thunderbird is unable to retrieve that mail. I've googled sendmail / dovecot config, I've looked a the wiki but I just can't figure this out. Please don't suggest using postfix, I just want to get sendmail / dovecot working. [@mail conf.d]# dovecot --version 2.2.10 [root@mail conf.d]# dovecot -n # 2.2.10: /etc/dovecot/dovecot.conf # OS: Linux 3.10.0-327.36.3.el7.i686 i686 CentOS Linux release 7.2.1511 (AltArch) auth_mechanisms = plain login disable_plaintext_auth = no mail_location = mbox:~/mail:INBOX=/var/mail/%u mbox_write_locks = fcntl namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } protocols = ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

mdbox+ ALT storage + lazyexpunge

All, Anyone know that if you setup lazyexpounge with mdbox that as ALT storage defined, whether the mail location for namespace used by lazyexpunge also need the ALT= specified ?? rgds Matt

mdbox + alt storage + purge = wtf ...
by Matt Bryant 13 Jul '18

13 Jul '18

All, Is there a bug in doveadm purge ? Configured alt storage and move messages in inbox to the alternate path all well and good. However, after deleting some messages and running a purge on the mailbox found that all messages got recopied over to primary location. I guess this maybe because its re-writing the file and ditching the purged mail .. but shouldnt it keep a track that they were located on alt storage path ?? rgds Matt

Question about verbose_proctitle
by J Doe 13 Jul '18

13 Jul '18

Hello, I have a question relating to the detail that the verbose_proctitle parameter enables for ps. I have TLS configured for IMAP as follows: /etc/dovecot/dovecot.conf ssl = required ssl_cert = </path/to/cert.pem> ssl_key = </path/to/key.pem> protocols = imap lmtp service imap-login { # Disable insecure IMAP over TCP 143 inet_listener imap { port=0 } } . . . verbose_proctitle = yes If I have a single MUA connect (Apple Mail in this case), I see: $ ps aux | grep -i dovevot dovenull 5552 0.0 0.1 18820 5444 ? S 18:53 0:00 dovecot/imap-login [1 connections (1 TLS)] vmail 5553 0.3 0.1 13612 4304 ? S 18:53 0:00 dovecot/imap [user(a)example.com 1.2.3.4 IDLE] The first part makes sense to me - imap-login is showing the user being connected via imap-login and with TLS. The second part, however, shows the IMAP session with the username, IP address and IMAP command (IDLE), but it does not state TLS. Does this mean that I have logins for IMAP connections protected by TLS but the actual IMAP traffic (mail contents, etc.), is *NOT* configured to use TLS ? That is to say, IMAP traffic is flowing over port 993 without TLS ? From the wiki [1] it appears to state that I only have to configure TLS settings for IMAP if the IMAP protocol is being secured via a *DIFFERENT* TLS certificate. Is this correct ? Thanks, - J Sources: [1] https://wiki2.dovecot.org/SSL/DovecotConfiguration

Whitelist file for LDAP authentication
by whpang 13 Jul '18

13 Jul '18

Hi, The dovecot version is 2.2.33.2 and we are using LDAP to do the authentication for SMTP service. We have the following configuration in auth-ldap.conf.ext to deny some users for LDAP auth. passdb { args = /etc/dovecot/deny.smtp driver = passwd-file deny = yes } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } And now we want to change the mechanism and only users in the list can send to LDAP auth and deny all others: passdb { args = /etc/dovecot/allow.smtp driver = passwd-file deny = no result_failure = return-fail result_internalfail = return-fail result_success = continue-fail } passdb { # Path for LDAP configuration file, see example-config/dovecot-ldap.conf.ext args = /etc/dovecot/dovecot-ldap.conf driver = ldap } Since we do not have the users’ password in the plain text file “allow.smtp”, the authentication process will fail and exit in the first passdb. Anyone can help to advice how to configure dovecot to have a whitelist for user LDAP authentication? Thank you very much.

Sieve_default
by ＠lbutlr 12 Jul '18

I created a sieve_default to move any spam-tagged messages into the Junk mailbox automatically, but it doesn’t appear to be working (though the other imapsieve_mailbox… scripts are working). From doveconf -n plugin { imapsieve_mailbox1_before = file:/usr/lib/dovecot/sieve/report-spam.sieve imapsieve_mailbox1_causes = COPY imapsieve_mailbox1_name = Junk imapsieve_mailbox2_before = file:/usr/lib/dovecot/sieve/report-ham.sieve imapsieve_mailbox2_causes = COPY imapsieve_mailbox2_from = Junk imapsieve_mailbox2_name = * imapsieve_mailbox3_before = file:/usr/lib/dovecot/sieve/mark-read.sieve imapsieve_mailbox3_causes = COPY imapsieve_mailbox3_name = Archive sieve = file:~/.sieve;active=~/.active_sieve sieve_default = /usr/lib/dovecot/sieve/default.sieve sieve_default_name = spamassassin sieve_global_extensions = +vnd.dovecot.pipe +vnd.dovecot.environment sieve_pipe_bin_dir = /usr/lib/dovecot/sieve sieve_plugins = sieve_imapsieve sieve_extprograms } And # cat /usr/lib/dovecot/sieve/default.sieve if header :contains "X-spam-flag" "YES" { fileinto "Junk"; } There are no user sieve files # find /home -name "*sieve*" -type f # The x-spam-flag header in the message in my mailbox is definitely there and definitely set to yes.
