Linking mailboxes
by Kunal A. 25 Feb '19

25 Feb '19

Hi, I am new to Dovecot and I am trying to link an email account folder to another Maildir(its a backup of the older email). I want the email account to be able to access the older emails. I am assuming this is done by creating a symlink? Currently reading instructions on this page:- https://wiki.dovecot.org/SharedMailboxes/Symlinks At the moment I have the folder:- /var/mail/vhosts/example.com/email1/Maildir/.INBOX.newfolder Inside the folder:- drwx------. 2 vmail vmail 4096 Feb 23 13:39 … [View More]cur -rw-------. 1 vmail vmail 232 Feb 23 13:43 dovecot.index.log -rw-------. 1 vmail vmail 51 Feb 23 13:43 dovecot-uidlist -rw-------. 1 vmail vmail 0 Feb 23 13:39 maildirfolder drwx------. 2 vmail vmail 4096 Feb 23 13:39 new lrwxrwxrwx. 1 root root 45 Feb 23 13:46 Other -> /run/media/computer/Storage/Email/mail/Other drwx------. 2 vmail vmail 4096 Feb 23 13:39 tmp lrwxrwxrwx. 1 root root 5 Feb 23 13:46 Users -> Users I am not able to access the folders in the Other folder structure(inside other there are other email inboxes ie(email1@example.com,email2@example.com,etc.). I want to get access to all the email subfolders. Could someone here advise how to do this or point me to some tutorials for this. Sincere apologies for this and many thanks in advance for helping...

Hi, today we had to hard-reboot one of our dovecot proxy backends and after boot up, lot's of accounts were showing this error and appeard empty: Error: Corrupted transaction log file ... After deleting the indexes (not uid file, problem wasn't in deleting indexes, i'm doing this often), e-mails showed up ok but e-mail clinets started to download them again. Why this happened and how to prevent it (other than 'not hard-rebooting')? I know that reboot could cause corruption of uid … [View More]

password protected ssl key seems unsupported after update to 2.3.4.1
by admin＠f-hamelin.fr 25 Feb '19

25 Feb '19

Hi, On a debian server after an update to dovecot to 2.3.4.1 imaps mail client stop working. I’ve applied necessary migration for ssl_dh (cf https://wiki.dovecot.org/Upgrading/2.3 <https://wiki.dovecot.org/Upgrading/2.3> ) but that was not enough. The workaround I’ve setup was to remove password protection from the ssl_key file. All tests with ssl_key_password parameter failled (direct password, <path-file-with-password) searching I’ve found a message reporting a problem with that … [View More]

permission denied errors with INDEX=MEMORY and trees plugin
by John McKay 24 Feb '19

24 Feb '19

I am using the trees[1] plugin to encrypt the mail on my disk. Because I don't want it to store any metadata in plaintext, I've also set INDEX=MEMORY in my mail_location configuration. However, whenever I get new mail I get errors like the following showing up in the journal: lmtp(john(a)octet.space)<21780><QDkrBqTXclwUVQAAQHGRUQ>: Error: Mailbox INBOX: Saving mail: read(/var/vmail/octet.space/john/Maildir/tmp/1551030180.M508113P21780.toaster.octet.space) failed: Permission denied … [View More](read reason=header Subject (Cache file is unusable)) It's like it's trying to read the message after it's been delivered, but is not able to because it's been encrypted. I seem to be able to get email just fine despite the error message. This happens both if I deliver mail using dovecot-lda or lmtp. Is there any way to fix this or at the very least suppress the error message? I have included my dovecot configuration below.

sieve filter not working
by subin ks 20 Feb '19

20 Feb '19

I've Dovecot and dovecot-sieve v 2.2.27 installed on a Debian 9.6. I'm trying to set a Sieve filter which will redirect all emails from `info` (i.e. .info) TLD to another email. This is the filter: require ["regex"]; # rule:[test] if header :regex "from" "info$" { redirect "subbs(a)domain.com"; } It's not being honored; all emails from .info TLD ends up in the inbox and none are redirected. Let me know what I'm doing wrong. Thanks.

Need to authenticate Outlook and NTLM
by Mark Foley 20 Feb '19

20 Feb '19

I've posted questions on this before, but now I really, really need a solution. Using Dovecot 2.2.33.2 We've been using Dovecot as IMAP server for several years on a Linux host which is also the Active Directory / Domain Controller. We have both Thunderbird and Outlook clients. The Thunderbird clients authenticate w/o problem with AD credentials using Kerberos/GSSAPI. I've never been able to get the Outlook clients to authenticate using domain credentials, so I've also hard-coded user and … [View More]password into /etc/passwd and let the Dovecot authenticate via PLAIN LOGIN. Now, however, I am mandated to switch all users to Outlook, so I need an AD credential solution. I found https://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm and followed those instructions. The first problem I ran into was in Step 3 where it said to put the following line in the config: auth_ntlm_use_winbind = yes This gave me an error when I restarted Dovecot: Restarting Dovecotdoveconf: Fatal: Error in configuration file /usr/local/etc/dovecot/conf.d/10-auth.conf line 84: Unknown setting: auth_ntlm_use_winbind googling this error indicated that this was a version 1.x directive and 2.x used only auth_use_winbind. I removed the auth_ntlm_use_winbind and Dovecot restart. If this is true, the wiki should be updated since it purports to be a version 2.x wiki. I followed the rest of the instructions on that wiki and my modified config is: $ doveconf -n # 2.2.33.2 (d6601f4ec): /usr/local/etc/dovecot/dovecot.conf # OS: Linux 4.4.157 x86_64 Slackware 14.2 auth_debug = yes auth_debug_passwords = yes auth_gssapi_hostname = $ALL auth_krb5_keytab = /etc/dovecot/dovecot.keytab auth_mechanisms = plain login gssapi ntlm auth_use_winbind = yes auth_username_format = %n auth_verbose = yes auth_verbose_passwords = plain disable_plaintext_auth = no info_log_path = /var/log/dovecot_info mail_location = maildir:~/Maildir passdb { driver = shadow } protocols = imap ssl_cert = </etc/ssl/certs/OHPRS/GoDaddy/Apache/2016-08-10/54e789087d419b6e.crt ssl_key = # hidden, use -P to show it userdb { driver = passwd } verbose_ssl = yes New additions to my pre-ntlm conf is only the 'ntlm' added the the auth_mechanism and: auth_winbind_helper_path = /usr/bin/ntlm_auth which interestingly doesn't show into the 'doveconf -n' output, above. Is it a default? I then attempted to connect from Outlook and got the error: auth: Info: ntlm(?,192.168.0.58,<qd9nulmB4sLAqAA6>): ntlm_auth reports broken helper: NT_STATUS_UNSUCCESSFUL After more searching I came across this post, https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=774263 which, in summary, said that ntlm_auth had to run as root. So, I added the following to my dovecot config per that post's suggestion: service auth { user = root } After restarting and trying again to connect from Outlook I got the message: auth: Info: ntlm(?,192.168.0.58,<SCINjFqBKcXAqAA6>): user not authenticated: NT_STATUS_NO_MEMORY At this point I've been unable to find a solution to this error. I've listed the entire dovecot log output for this last attempt to connect from Outlook below. Has anyone in the Universe successfully connected from Outlook using active domain credentials? If so, what's the secret? What am I not doing correctly?

dovecot/lmtp dumps core when proxying to multiple recipients via protocol=smtp
by Piper Andreas 19 Feb '19

19 Feb '19

Hello, when trying to set up a migration scenario from my old mailbox-servers to my new dovecot-cluster, I get a coredump from dovecot/lmtp when proxying mail-delivery to more than one recipient on the old mailbox-server. My setup: 3 director-hosts (Debian stretch) are proxying to a pair of replicator-hosts and during migration also to the old mailbox-server. For migration the not-migrated user-addresses are included via a passwd-file with entries like: grtest1@hrz.uni-marburg.de:::::::… [View More]director_tag=hrz protocol=smtp user=grtest1 grtest2@hrz.uni-marburg.de:::::::director_tag=hrz protocol=smtp user=grtest2 ... The director_tag points to the old mailbox-server, with 'protocol=smtp' SMTP is used for delivery, as the old machine is not capable of LMTP. The setup works fine for imap-proxying and for mail-delivery to single recipients. But if a mail is addressed to more than one recipient, lmtp produces a coredump after delivering to all recipients. The error-message in the log is: Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): Connect from 127.0.0.1 Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): 206UIrlNZVyX/AAAGwthQA: Sent message to <grtest2> at 137.248.xxx.yyy:25: 250 2.0.0 x1EBF5Ro016092 Message accepted for delivery (1/2 at 79 ms) Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): 206UIrlNZVyX/AAAGwthQA: Sent message to <grtest2> at 137.248.xxx.yyy:25: 250 2.0.0 x1EBF5Ro016092 Message accepted for delivery (2/2 at 79 ms) Feb 14 12:15:05 vhrzxxx dovecot[63861]: lmtp(64663): Fatal: master: service(lmtp): child 64663 killed with signal 11 (core dumped) The backtrace from the coredump is: Reading symbols from /usr/lib/dovecot/lmtp...(no debugging symbols found)...done.

Migrate mail data from Dovecot to Dovecot
by Odhiambo Washington 19 Feb '19

I have built a new server (FreeBSD-12) running dovecot-2.3.4. My old server (FreeBSD-9.3) is running dovecot-2.3.4 as well. The configurations are 1:1 identical.

Now, to migrate the mail data, can I simply rsync the mail directories between the old and the new server? Would that create a pitfall?? What is the recommended method? -… [View More]
