Re: Sendmail Dovecot Trouble
by John Rowan 18 Jul '18

Having reinstalled CentOS 7 including e-mail server in initial software configuration it installed Postfix/Dovecot. I've been using Sendmail for 20 years and no experience with Postfix. Looked in Webmin -> servers -> Postfix and specified Maildir, changed the 10-mail.conf to specify mail_location = maildir:~/Maildir and everything's working. Thanks for help.

best practices for migrating to new dovecot version
by Shawn Heisey 18 Jul '18

18 Jul '18

I have a machine with my mail service on it running Debian Squeeze. The version of dovecot on that server is 1.2.15. I'm building a new server with Ubuntu 18.04 (started with 16.04, upgraded in place), where the dovecot version is 2.2.33. I plan to migrate all my services to this new machine. The virtual mailboxes are on disk in maildir format, with accounts in a mysql database managed by postfixadmin. When I copy them over to the new machine, would there be any value to excluding the files that dovecot creates, and letting the new version recreate them? In one mailbox here are some of the files I am considering excluding: dovecot.index dovecot.index.cache dovecot.index.log dovecot.index.thread dovecot-keywords dovecot-uidlist dovecot-uidvalidity dovecot-uidvalidity.5876ca77 There are other files under consideration, like maildirsize and maildirfolder. One that I would be sure to *not* remove is subscriptions. If there are recommendations about dovecot files in a maildir that should not be removed during a migration, please let me know. I'm aware that rebuilding this information could be slow. My own personal mailbox on the system is over 8GB in size and has well over nine hundred thousand files in it. Thanks, Shawn

Dovecot Quota and subject utf-8

18 Jul '18

Hi. When a user is over quota and a message is rejected, it sends a message back changing partially the subject (depending on the size). With utf-8 it breaks the information, we noticed this behavior when the subject line uses utf-8 and it is broken in more than one line: Subject: Quêm casé erat vim id, vix ín dicit putânt, minim çónsequuntur ea iús.

Any ideas? Best wishes, Sophie

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 + purge = wtf ...

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 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.

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

LMTP crashing heavily for my 2.2.36 installation
by Wolfgang Rosenauer 11 Jul '18

Hi, I'm running 2.2.36 (as provided by openSUSE in their server:mail repository) and at least at one of my systems LMTP is crashing regularly on certain messages (apparently a lot of them).

Dovecot API for Email Archive
by Nduduzo Phili 11 Jul '18

11 Jul '18

Good day, Is there a Dovecot API for version 2.2.15 and/or above that can be used to archive to Microsoft Archive Storage OR, Is there another tool or cloud archive platform you are aware of that could assist with this? Thank you. [cid:image001.png@01D41918.B96DB030] Nduduzo Phili Product Manager ______________________________________ D: 087 805 1146 | M: A: nduduzo.phili(a)voxtelecom.co.za www.vox.co.za
