Question about verbose_proctitle
by J Doe 14 Jul '18

14 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.

Hello! I have a problem with a sieve-script which works for one domain but not for another one. Both domains are hostet on the same server running dovecot and postfix. This is the script that works: require ["vacation"]; # rule:[Out of office] if true { vacation :days 1 :addresses "a.meyer(a)nimmini.de" :subject "absent" "Ich bin nicht da."; } This one does not, a vacation message is not sent: require ["vacation"]; # rule:[Out of office] if true { vacation :days 1 :addresses "a.meyer(a)bitcorner.de" :subject "absent" "Ich bin nicht da."; } I don't know why. A sieve-test shows # sieve-test ./managesieve.sieve ./testfile -D sieve-test(andreas): Debug: sieve: Pigeonhole version 0.4.2 initializing sieve-test(andreas): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts. debug: script binary ./managesieve.svbin is not up-to-date. debug: script `managesieve' from ./managesieve.sieve successfully compiled.

Re: Authentication failure with OpenLDAP
by Anushka Bandara 12 Jul '18

12 Jul '18

Hi all, Thank you all for the help. The was with the ldap user attributes. I corrected it. Now I am having an error with dovecot. User can log into ldap but, system doesn't allow user to create user's directory in Maildir. Error is below, * Error: User initialization failed: Namespace '': mkdir(/home/users/"user"/Desktop/Maildir) failed: Permission denied (euid=1000(myuser) egid=5000(<unknown>) missing +w perm: /home, we're not in group 100(users), dir owned by 0:100 mode=0775)* How should I give the permission to overcome this error. This is a dovecot error. LDAP authentication is successful. And also, I don't know the default user whom is creating mail directories for mail users. I think the problem will be solved if I grant user the permission. But I don't know how to grant.

Storing Messages in the cloud
by Jerry 12 Jul '18

12 Jul '18

A colleague asked me if it was possible for Dovecot to store messages in the cloud. I have not heard of it being done and therefore assume it is not possible, but I thought I would ask regardless. I tried checking on the “One Drive” forum; however, I have not received any response back yet. Thanks! -- Jerry
