Is it possible to (re)direct only 1 imap user to the new server
by Marc Roos 14 May '19

14 May '19

I haven't used dovecot proxy or director. If I have a setup where all my users are connecting to HOSTNAMEOLD, is it possible to have 1 imap user that is connecting to HOSTNAMEOLD directed/forwarded to HOSTNAMENEW? Without changing my dns settings and preferably without creating any new servers. I think I can route one users mail to HOSTNAMENEW with sendmail ldap routing. So the only thing I need to be able to do is have the incoming imap requests on HOSTNAMEOLD been handled by HOSTNAMENEW. HOSTNAMEOLD HOSTNAMENEW +--------------+ +--------------+ | SENDMAIL | | SENDMAIL | | | | | | | | | | | V | | V | |--------------| |--------------| | lmtp | | NS /INBOX | | | | | mbox on | | V | | block device | |--------------| | | | NS /INBOX | |--------------| | mdbox on | | NS /ARCHIVE | | block device | | mdbox on | | | | clustered fs | |--------------| | | | NS /ARCHIVE | +--------------+ | mdbox on | | clustered fs | | | +--------------+

email notification regression between 2.2 and 2.3
by Thomas Capricelli 14 May '19

14 May '19

Hi, Hello. For the last year, each time i've tried updating dovecot from 2.2.x to 2.3.x, I had to rollback because of the following problem: Users don't "see" new emails arriving in subdirs. To be specific * we mostly use/tested thunderbird client * we use maildrop for delivery * this is using imap, not pop3 * when a new email arrives, thunderbird renders the dir name in blue and appends a "(1)" (or more..). That's what we call 'see' * this happens only on 'subdirs', not the main directory. * the server is a typical linux amd64, using the gentoo distribution More testing shows that * if we switch delivery to dovecot-lda, it works ok. But we can't commit that change, or at least not now/easily. Our users heavily use .mailfilter * if the user is currently viewing the subdir, then email notification is working * better : if the user went on the subdir and then in another dir, it keeps on working. It seems we need to 'open' it at least once for notification to work * "maildir_very_dirty_syncs = no" doesn't help (we had =yes) * "mailbox_list_index = no" doesn't help * i can confirm inotify was detected/used in autoconf when installed (anyway it works well with 2.2) I'm always on freenode (orzel). I'll be in #dovecot the next days at least. greetings, -- Thomas Capricelli

Userdb userdb_mail=, error Mailbox list driver maildir++: maildir_name not supported by this driver
by Marc Roos 14 May '19

14 May '19

I have this default configuration [0], when use the userdb_mail to point to the mdbox location, the inbox subfolders show differently in a firebird client. So I decided to copy the whole default mail_location into the userdb_mail configuration [2]. But then I get errors [3]. Should I change the namespace configuration here, how? My default namespaces are inbox and 4archives [0] [@ ]# doveconf | grep mail_loc mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u:CONTROL=~/mail/control:INDEX=/var/d ovecot/%u/index:LAYOUT=maildir++ [1] [@dovecot]# cat special-userdb test:x:8267:231:Account with special settings for dovecot:/home/popusers/test:/bin/false:userdb_mail=mdbox:~/mdbox [2] [@dovecot]# cat special-userdb test:x:8267:231:Account with special settings for dovecot:/home/popusers/test:/bin/false:userdb_mail=mdbox:~/mdbox:INBOX=/ var/spool/mail/%u:CONTROL=~/mail/control:INDEX=/var/dovecot/%u/index:LAY OUT=maildir++ [3] May 13 22:41:32 mail04 dovecot: imap-login: Login: user=<test>, method=PLAIN, rip=192.168.10.219, lip=192.168.10.44, mpid=1138, TLS, session=<Gk4K8cqIkdHAqArb> May 13 22:41:32 mail04 dovecot: imap(test): Debug: Loading modules from directory: /usr/lib64/dovecot May 13 22:41:32 mail04 dovecot: imap(test): Debug: Module loaded: /usr/lib64/dovecot/lib15_notify_plugin.so May 13 22:41:32 mail04 dovecot: imap(test): Debug: Module loaded: /usr/lib64/dovecot/lib20_listescape_plugin.so May 13 22:41:32 mail04 dovecot: imap(test): Debug: Added userdb setting: mail=mdbox:~/mdbox:INBOX=/var/spool/mail/test:CONTROL=~/mail/control:IND EX=/var/dovecot/test/index:LAYOUT=maildir++ May 13 22:41:32 mail04 dovecot: imap(test): Debug: Effective uid=8267, gid=231, home=/home/popusers/test May 13 22:41:32 mail04 dovecot: imap(test): Debug: Namespace inbox: type=private, prefix=, sep=/, inbox=yes, hidden=no, list=yes, subscriptions=yes location=mdbox:~/mdbox:INBOX=/var/spool/mail/test:CONTROL=~/mail/control :INDEX=/var/dovecot/test/index:LAYOUT=maildir++ May 13 22:41:32 mail04 dovecot: imap(test): Error: Namespace '': Mailbox list driver maildir++: maildir_name not supported by this driver May 13 22:41:32 mail04 dovecot: imap(test): Namespace '': Mailbox list driver maildir++: maildir_name not supported by this driver in=0 out=378

I want to monitor a special folder and execute a shell script each time I put an email to it. I would like to automate that way the process of SPAM reporting (SPAMCop). Is that possible with sieve? Lefteris

Doveadm sync, Error: read(remote) failed: EOF, Error: read(remote) failed: EOF
by Marc Roos 13 May '19

13 May '19

In the manual page this command is used for converting a mailbox doveadm sync -u test mdbox:~/mdbox -x INBOX -x INBOX/* Yet I am getting this error and the mdbox folder is not created. dsync-local(test): (version not received) doveadm(test): Fatal: execvp(mdbox:~/mdbox) failed: No such file or directory [@ dovecot]# doveconf | grep mail_locat mail_location = mbox:~/mail:INBOX=/var/spool/mail/%u:CONTROL=~/mail/control:INDEX=/var/d ovecot/%u/index:LAYOUT=maildir++ Users are not having shell access so something like su test -c '' will also not work. What would be a work-around for this?

dovecot 2.2.36 and wforce
by Tobi 13 May '19

13 May '19

Hi list I'm trying to setup dovecot 2.2.36 on a Centos6 to communicate with a wforce daemon on the remote side. wforce is latest released from git repo. Daemon part is working and I can successfully send queries from remote systems to wforce via curl For dovecot I configured in /etc/dovecot/conf.d/95-wforce.conf > auth_policy_server_url = http://REMOTE_IP:8084/ > auth_policy_hash_nonce = my_random > auth_policy_server_api_header = Authorization: Basic <BASE64 of wforce:my_password> > auth_policy_request_attributes = login=%{requested_username} pwhash=%{hashed_password} remote=%{rip} device_id=%{client_id} protocol=%s restarted dovecot without errors, but upon testing via imap I cannot see just one single tcp paket leaving direction REMOTE_IP on port 8084. It looks like auth policy in not involved at all. Thanks for any idea tobi

Re: Re: Dovecot not surviving OpenLDAP restart
by Dag Nygren 12 May '19

12 May '19

One more obvious line from the log: dovecot[26621]: auth: Error: LDAP: Connection lost to LDAP server, reconnecting Where it claims to reconnect, but after that there is no LDAP authentication. And the same configuration has worked fine since at least 10 years ago up to some recent update of dovecot or openldap. Best Dag

IMAPSieve message marked as HAM should go through full sieve script of user
by Matthias Fechner 10 May '19

10 May '19

Dear all, I use the IMAPSieve implementation described here: https://wiki.dovecot.org/HowTo/AntispamWithSieve It is working really great! Thanks a lot for this. The problem I have now is: A message was by accident marked by rspamd as spam, so a false-positive and is moved to the Junk folder. If I click in my email program now on `Not Spam` it is learn as HAM but moved to the INBOX. I would like that the email is not moved to INBOX but it should be moved through the sieve script of the user again, as it is a new email. Currently I have to mark all false-positives as not spam and have then to manually move it to the correct subfolder which is a bit annoying. Is this possible? Thanks a lot! -- Gruß Matthias

I am trying to find out if Dovecot supports "smtputf8". Obviously, I am looking in the wrong places, but I just cannot find a definitive answer. Thanks! -- Jerry
