[Dovecot] Sieve filterset not activating in Dovecot 2.0.15 with Sieve plug-in and Roundcube 0.5.3: "NO (TRYLATER) Internal Error."
by Joe Lourenco 22 Aug '13

22 Aug '13

Hello Everyone, I am running Dovecot 2.0.15 with its Sieve plug-in, and Roundcube 0.5.3. I have a problem with just one particular user, who after creating a filters set and creating a filter in Roundcube, this user cannot activate the filters set. At first, this user could not create a filter at all. That was resolved by creating the "sieve" directory with the right permissions in his /home. Logs show the following when trying to activate the filters set via the Roundcube: roundcube: S: NO (TRYLATER) "Internal error occured. Refer to server log for more information. [2013-08-21 19:01:13]" Nothing is showing up on the server log. I have tried to activate the filter via the Sieve command line, authenticating the user, then running "SETACTIVE "roundcube"", but the error is the same, an internal server error. Again, I can successfully do this via the command line or Roundcube, from say, my userid. I appreciate any help. -- Joe Lourenco Systems Administrator C & C Technologies Cell: 55-21-8596-0078 Phone: 55-21-2499-9591

[Dovecot] dovecot2, antispam and sieve versions
by Terry Barnum 22 Aug '13

22 Aug '13

I'm currently running dovecot2 v2.2.5 with dovecot2-antispam 0.0-51 and dovecot2-sieve 0.4.1, all via macports. If one wanted to downgrade to dovecot v2.2.0, would these versions of antispam and sieve still be okay to use? The reason for the question is I'm trying to diagnose a mailserver problem where after 2-6 days the machine goes deaf. Absolutely nothing of interest in any logfile that I can see except for an imap-login process crash which got me thinking about a downgrade test. Thanks, -Terry Terry Barnum digital OutPost http://www.dop.com

[Dovecot] Dovecot antispam plugin for 2.2
by Micah Anderson 21 Aug '13

21 Aug '13

Hello, I recently was looking to update to dovecot 2.2 and I have been happily using the dovecot-antispam plugin in 2.1, but found that there have been some changes in dovecot that make this version not compile against 2.2. I'm wondering if Johannes you have any plans to update it, or if others have managed to figure out what is necessary to get it to work? The particular piece that I am currently stuck on is that the dict_init() in dovecot now requires more arguments than in previous versions, it now requires this: int dict_init(const char *uri, enum dict_data_type value_type, const char *username, const char *base_dir, struct dict **dict_r, const char **error_r); but previously, we only needed four arguments. Now we need to know what to supply for '**dict_r' and '**error_r'. Any advise/help would be appreciated: make[1]: Entering directory `/home/micah/debian/dovecot-antispam/dovecot-antispam-2.0+20120225' cc -DHAVE_CONFIG_H -I/usr/include/dovecot/ -I/usr/include/dovecot/src/ -I/usr/include/dovecot/src/lib/ -I/usr/include/dovecot/src/lib-storage/ -I/usr/include/dovecot/src/lib-mail/ -I/usr/include/dovecot/src/lib-imap/ -I/usr/include/dovecot/src/lib-dict/ -I/usr/include/dovecot/src/lib-index/ -I/usr/include/dovecot/src/imap/ -o dovecot-version dovecot-version.c ./dovecot-version > dovecot-version.h CC antispam-storage.o In file included from antispam-storage-2.2.c:20:0, from antispam-storage.c:3: antispam-plugin.h: In function ‘string_dict_init’: antispam-plugin.h:288:2: error: too few arguments to function ‘dict_init’ return dict_init(uri, DICT_DATA_TYPE_STRING, username, NULL); ^ In file included from antispam-plugin.h:13:0, from antispam-storage-2.2.c:20, from antispam-storage.c:3: /usr/include/dovecot/dict.h:34:5: note: declared here int dict_init(const char *uri, enum dict_data_type value_type, ^ micah

[Dovecot] Dsync confusion...
by Ben 21 Aug '13

21 Aug '13

Hi, Maybe I've been staring at config files and man pages too long, but the doc page for Dsync is a little confusing and I don't how to solve my problem. I've probably missed something simple and stupid, but as I said, I've been staring at this problem too long and need a second pair of eyes on it ! Per doveconf below the user/owner for auth db is a user with shell /bin/false. Root SSH login is also disabled on the target machine, so I need to use a script user to do the sync. I installed dovecot on the target host and config'd it as per the second doveconf below But all I ever get are errors such as : su -c "dsync -u test(a)somewhere.example.com backup its-virtmail(a)somewhere.example.com" its_scripts dsync(its_scripts): Fatal: setuid(1001(its-virtmail) from userdb lookup) failed with euid=1002(its_scripts): Operation not permitted (This binary should probably be called with process user set to 1001(its-virtmail) instead of 1002(its_scripts)) root@ukc-vm02-mx01:/etc/dovecot/conf.d# dsync(its_scripts): Error: userdb lookup: connect(/var/run/dovecot/auth-userdb) failed: Permission denied (euid=1002(its_scripts) egid=1002(its_scripts) missing +r perm: /var/run/dovecot/auth-userdb, dir owned by 0:0 mode=0755) Even if I temporarily give /bin/sh and an ssh key to the dovecot user, I still can't get it to work : ssh its-virtmail(a)somewhere.example.com dsync -u test(a)example.com dsync(its-virtmail): Error: user test(a)somewhere.example.com: Initialization failed: mail_location not set and autodetection failed: Mail storage autodetection failed with home=/srv/mail/example.com/test dsync(its-virtmail): Fatal: User init failed dsync-local(test(a)somewhere.example.com): Error: read() from worker server failed: EOF # SOURCE HOST # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-37-generic x86_64 Ubuntu 12.04.2 LTS auth_verbose = yes auth_verbose_passwords = sha1 mail_location = maildir:~/Maildir managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { fts = solr fts_solr = url=http://localhost:8080/solr/ sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp sieve service auth { unix_listener /var/spool/postfix/private/dovecot-auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = its-virtmail mode = 0660 user = its-virtmail } } service imap-login { process_min_avail = 3 } service lmtp { process_min_avail = 5 unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } user = its-virtmail } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieves { port = 5190 ssl = yes } process_min_avail = 3 } ssl = required ssl_cert = </etc/ssl/certs/mx_example.com.pem ssl_cipher_list = TLSv1+HIGH:!SSLv2:!aNULL:!eNULL:!3DES:!PSK:@STRENGTH ssl_key = </etc/ssl/private/mx_example.com.key userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } protocol imap { imap_client_workarounds = delay-newmail mail_max_userip_connections = 10 mail_plugins = fts fts_solr } protocol pop3 { mail_max_userip_connections = 10 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } protocol lda { deliver_log_format = msgid=%m: %$ mail_plugins = sieve postmaster_address = postmaster quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r } protocol lmtp { mail_plugins = sieve postmaster_address = postmaster(a)example.com } #DEST HOST # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.5.0-37-generic x86_64 Ubuntu 12.04.2 LTS auth_verbose = yes auth_verbose_passwords = sha1 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap lmtp sieve" service auth { unix_listener auth-userdb { group = its-virtmail user = its-virtmail } } service lmtp { process_min_avail = 3 user = its-virtmail } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file }

[Dovecot] Delivering message to other mailbox
by Frank de Bot 21 Aug '13

21 Aug '13

Hi, On my mailserver I have for each mailbox a sieve script to put Spam-marked message into a folder (match header, then fileinto 'Spam'). This works, but I want to deliver spam-marked messages to a different mailbox. For each user a seperate mailbox is created next to the existing mailbox, allowing different authentication. How can I do this with dovecot/pigeonhole? I figured out I could redirect is the user.spam@domain which delivers to the other mailbox, but it will go into a new delivery process with amavis set up. (There's no point to scan a single message twice). Is there a way I can accomplish to directly deliver a spam-marked message to a different mailbox? Regards, Frank de Bot

[Dovecot] Using procmail to mark messages as read in dovecot
by LuKreme 20 Aug '13

So, I use procmail extensively, and I have for a long time, but marking messages as 'read' in a Maildir has always been a little wonky: TRAP='mv "$LASTFOLDER" "${LASTFOLDER}:2,S"' Since I've switched to dovecot, is there a way to mark a message on delivery as read or not new or seen? -- Clarke's Law: Sufficiently advanced technology is indistinguishable from magic

[Dovecot] Maximum number of connections from user+IP exceeded

All of a sudden I am getting these errors on one of my accounts: imap-login: Info: Maximum number of connections from user+IP exceeded (mail_max_userip_connections=10) It was working fine last night when I went to bed, and is posting these errors nearly constantly (about one every second) when I checked mail after waking up this morning. The account is question is my main account and has a lot of mail, but it is not the account with the most mailboxes, that one is working fine. I looked at the documentation on how to increase this setting, but <http://wiki.dovecot.org/MainConfig> is for 1.x and clicking the 'wiki2" link brings up a mostly blank page with no configuration info at all.

[Dovecot] Calling dovecot-lda correctly from exim for virtual user setup
by Frerich Raabe 20 Aug '13

20 Aug '13

Hi, I'm running Dovecot 2.1.7 on Debian. Exim is the MTA. I was recently made aware of the fact that the way in which Exim invokes dovecot-lda is prone to code injection: dovecot_virtual_delivery: driver = pipe command = HOME=/home/vmail/\$local_part /usr/lib/dovecot/dovecot-lda -f \$sender_address use_shell .. I.e. a command is executed via the shell, and Exim uses non-sanitized user input (mail header fields) to construct the command. Now, the reason I invoked dovecot like that is to pass a plausible value for the HOME environment variable, so that dovecot-lda can determine where the Maildir directory of the recipient is. Is there any way to achieve this without requiring HOME to be set correctly? I looked at the -m switch but as far as I can see that merely defines the destination mailbox, but not the path to the Maildir directory, correct? -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

Typically you could use "sealert -a /var/log/audit/audit.log /var/log/audit/audit.log.1" to get a feel for how many SELinux exceptions are happening. Also, when you say that the restorecon -R did not fix the issue, did you check the output of "ls -Z" after running it? However, looking at your original message, I'm wondering why the forward slashes are doubled up. For instance: "/home/user/data1/Maildir//"

[Dovecot] Disagreement on where mail goes.
by LuKreme 19 Aug '13

19 Aug '13

My virtual users have their mail stored in /usr/local/virtual/user(a)example.com/ dovecot wants to read the mail from /usr/local/virtual/user(a)example.com/Maildir which is causing problems since all new mail is being written in /usr/local/virtual/user(a)example.com/new and dovecot is looking in /usr/local/virtual/user(a)example.com/Maildir/new For the local users, /home/user/Maildir is the right directory. for right now I've had to kludge a script that moves mail from /usr/local/virtual/user(a)example.com/new to /usr/local/virtual/user(a)example.com/Maildir/new every two minutes. -- First we must assume a spherical cow.

Since I am using dovecot I do not have courier installed, but Courier had a very handy tool for making maildir folders called `maildirmake` which I used in some automated backup scripts.

For example, this works: # doveadm auth test 'someuser*masteruser' Password: <enter master user's password here> passdb: someuser*masteruser auth succeeded but depends on the existence of another user, and is thus contingent and unnecessarily heavy.

[Dovecot] rdiff-backup of Maildir?
by Thomas Harold 16 Aug '13

16 Aug '13

What's the best way to do long-term backups of the Maildir format these days? Traditionally we've just done a rdiff-backup or pointed Bacula at the Maildir. Both give us the option to reset a particular mailbox back to a previous day (any day within the last N months). Do we just need to snapshot the LVM volume that holds all the Maildir boxes, or is there some additional commands that we should run before doing the LVM snapshot?

[Dovecot] IMAP Proxying and SSL Certificates on OpenBSD
by dago＠quantentunnel.de 16 Aug '13

Hi list, I am currently trying to configure dovecot to act as a imap proxy in front of a Groupwise server. Because of a policy no services of the gw server may be directly served to the web. So currently this is only a security measure. Dovecot was previously used for providing sasl-auth capabilities to postfix. IMAP proxy features should be added now. Authentication backend is LDAP. OS is OpenBSD 5.2. Dovecot version is 2.1.8. Currently I am fighting with the following error in the logs: dovecot: master: Dovecot v2.1.8 starting up dovecot: auth: Warning: userdb passwd: Move templates args to override_fields setting dovecot: auth: Error: passwd(username,78.104.X.X,<e9YE/gDkOQBOaKfg>): getpwnam() failed: Operation not permitted dovecot: imap-login: Login: user=<username>, method=PLAIN, rip=78.104.X.X, lip=5.9.X.X, mpid=1765, session=<e9YE/gDkOQBOaKfg> dovecot: imap(username): Error: user username: Initialization failed: Initializing mail storage from mail_location setting failed: imapc: missing imapc_password dovecot: imap(username): Error: Invalid user settings. Refer to server log for more information. I hope to also see therein the cause for not providing STARTTLS: # openssl s_client -connect mail.example.com:143 -starttls imap CONNECTED(00000003) didn't found STARTTLS in server response, try anyway... 15096:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s23_clnt.c:607: As postfix is already using the certificates, they should be okay …. # dovecot -n # 2.1.8: /etc/dovecot/dovecot.conf # OS: OpenBSD 5.2 i386 disable_plaintext_auth = no imapc_host = 10.0.0.2 mail_gid = vmail mail_home = /home/vmail/%u mail_location = imapc:~/imapc mail_uid = vmail passdb { args = scheme=plain-md5 username_format=%n /etc/dovecot/passwd driver = passwd-file } passdb { args = /etc/dovecot/dovecot-ldap.conf default_fields = userdb_imapc_user=%u userdb_imapc_password=%w driver = ldap } protocols = imap service auth { unix_listener /var/spool/postfix/private/auth { group = _postfix mode = 0660 user = _postfix } user = root } service imap-login { chroot = login } service pop3-login { chroot = login } ssl = no ssl_ca = </etc/ssl/ca.crt ssl_cert = </etc/ssl/pf/mail.example.com.crt ssl_key = </etc/ssl/pf/mail.example.comkey userdb { args = username_format=%n /etc/dovecot/passwd driver = passwd } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } # dovecot-ldap.conf hosts = 10.0.0.2:389 dn = cn=ldapaccess,o=servercontext dnpass = secretpass auth_bind = yes ldap_version = 3 base = o=usercontext user_attrs = homeDirectory=home,uidNumber=uid,gidNumber=gid user_filter = (&(&(objectClass=Person)(cn=%u))(groupMembership=cn=SMTPsender,o=permissiongroups)) pass_attrs = cn=user,userPassword=password pass_filter = (&(&(objectClass=Person)(cn=%u))(groupMembership=cn=SMTPsender,o=permissiongroups)) Thanks in advance!

[Dovecot] Problems with openssl library path
by Christian Felsing 16 Aug '13

Hello, I tried to compile Dovecot 2.2.5 on Debian 6 with an alternate OpenSSL installation located at /usr/local/ssl A compilation with CPPFLAGS="-I/usr/local/ssl/include" \ LDFLAGS="-L/usr/local/ssl/lib -Wl,-rpath=/usr/local/ssl/lib" \ SSL_LIBS="-L/usr/local/ssl/lib -Wl,-rpath=/usr/local/ssl/lib" \ ./configure \ --prefix=/opt/dovecot-2.2.5 \ --enable-asserts \ --enable-largefile \ --with-ldap=yes \ --with-zlib \ --with-bzlib \ --with-libcap \ --with-ssl=openssl \ --with-gc \ --with-storages=maildir,mbox,mdbox,cydir \ create a working Dovecot, but it still uses the very old Debian 6 OpenSSL 0.9.8 instead my OpenSSL 1.0.1e LD_LIBRARY_PATH has also no effect, because Dovecot strips it out. Any hints? regards Christian
