Move dovecot between servers
by Gandalf Corvotempesta 30 Aug '16

30 Aug '16

Hi to all I have a very old dovecot server (1.2.15) with about 195GB used and 1081 email accounts. I have to move this server to another one with contextual dovecot upgrade. Anyone did this before? Any advice? Obviously, existing emails *must not* be downloaded twice by existing clients (outlook, thunderbird, ...) I have no access to customer's clients, only to my server.

sieve-filter with duplicate-extension
by hendrik＠luecke-tieke.de 26 Aug '16

26 Aug '16

Hi, i have imported a mailbox twice (accentially). Now i thought, it might be a valid approach to simply use a custom sieve rule to mark duplicates using the attached ruleset I ran sieve-filter like this: ~# sieve-filter -e -W -v -C -u userxyz(a)example.com /var/vmail/example.com/userxyz/sieve/duplicates.sieve 'INBOX' But sieve-filter complains like this: info: msgid=<1231321313212312312312(a)p3enginer2.emv2.com>: left message in mailbox 'INBOX'. info: message kept in source mailbox. info: filtering: [Sun, 1 May 2011 16:41:46 +0100; 101297 bytes] `Cipo & Baxx, Nike Golf, Strenesse, al...'. roundcube2: line 3: warning: duplicate test: duplicate checking not available in this context. info: msgid=<1123123123123123(a)p3enginer3.emv2.com>: left message in mailbox 'INBOX'. info: message kept in source mailbox. info: filtering: [Sun, 28 Oct 2012 11:32:56 +0100; 1416 bytes] `DenyHosts Report for example.com'. roundcube2: line 3: warning: duplicate test: duplicate checking not available in this context. Is there a way, to refilter an existing mailbox and applying the duplicate extension? Many thanks and best regards, Hendrik

quota-status service rejecting plus addressed recipients
by Robert Brooks 26 Aug '16

26 Aug '16

Hi, I have "recipient_delimiter = +" set in my Dovecot config, however the Dovecot quota-status service is rejecting with "Unknown user" plus addressed recipients. Talking to the policy server we have... # telnet localhost 12340 > Trying 127.0.0.1... > Connected to localhost. > Escape character is '^]'. > recipient=user(a)example.com > > action=OK > > recipient=user+foo(a)example.com > > action=REJECT Unknown user > I can mask the issue with "quota_status_nouser = DUNNO", but then over quota messages are not rejected when plus addressed. quota-status service config is... service quota-status { > executable = quota-status -p postfix > inet_listener { > address = localhost > port = 12340 > # You can choose any port you want > } > client_limit = 1 > } > Regards, Rob

maildirsize not correct
by Kamil Madac 26 Aug '16

26 Aug '16

Hi, One of my email accounts has 1,5gb of emails in INBOX, but maildirsize shows only 528mb. 'du' also shows 1,5gb and there are 3809 files in cur directory. When I use mailbox status a can see correct values: doveadm -f table mailbox status -u user(a)domain.sk "messages vsize" INBOX* messages vsize INBOX 3809 1521049349 but when I check the quotas with doveadm: doveadm quota get -u user(a)domain.sk Quota name Type Value Limit % User quota STORAGE 541391 2048000 26 User quota MESSAGE 886 - 0 I tried to delete maildirsize, but it was recalculated again incorrectly. 2097152000S 554384829 886 Dovecot version is 2.2.9 installed from packages on Ubuntu 14.04 I have other accounts on server which are have no problems with maildirsize and quotas. Does anyone have same experience? Kamil

lazy_expunge and public folder
by Arne Hoffmann 26 Aug '16

26 Aug '16

Hi all, I stumbled upon the lazy_expunge plugin and thought that it might be useful in some cases. It works fine if I delete mails from my inbox. But it doesn't do anything if I deleted mails from a public folder (and for the server I am currently working on the public folder is _the_ _main_ _feature_). Does lazy_expunge not work with public folders? Or am I using it wrong? root@imap01 [~]# doveconf -n # 2.2.24 (a82c823): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 3.16.0-4-amd64 x86_64 Debian 8.5 ext4 auth_debug = yes auth_debug_passwords = yes debug_log_path = /var/log/mail.debug disable_plaintext_auth = no doveadm_password = # hidden, use -P to show it doveadm_port = 22001 mail_debug = yes mail_location = maildir:/var/mail/vmail/%d/%n/Maildir:INBOX=/var/mail/vmail/%d/%n/Maildir mail_plugins = " listescape lazy_expunge notify replication" mail_privileged_group = vmail namespace { location = maildir:/var/mail/vmail/Öffentliche Ordner:INDEXPVT=~/Maildir/Öffentliche Ordner mailbox "Gelöschte Elemente" { auto = subscribe special_use = \Trash } mailbox MirrorServer-Projekt { auto = subscribe } prefix = Öffentliche Ordner/ separator = / subscriptions = no type = public } namespace { hidden = yes list = no location = maildir:~/Maildir/expunged prefix = .EXPUNGED/ separator = / } namespace inbox { inbox = yes location = prefix = separator = / type = private } passdb { args = /etc/dovecot/mysql.conf driver = sql } plugin { lazy_expunge = .EXPUNGED/ mail_replica = tcps:imap02.example.com } protocols = imap service aggregator { fifo_listener replication-notify-fifo { user = vmail } unix_listener replication-notify { user = vmail } } service doveadm { inet_listener { port = 22001 ssl = yes } } service replicator { process_min_avail = 1 unix_listener replicator-doveadm { group = vmail mode = 0660 } } ssl = required ssl_ca = </etc/ssl/os/cert-sub-ca1-and-root-ca.pem ssl_cert = </etc/ssl/os/cert-imap01-example.com.pem ssl_client_ca_file = /etc/ssl/os/cert-all.pem ssl_client_cert = </etc/ssl/os/cert-imap01-example.com.pem ssl_client_key = </etc/ssl/os/key-imap01-example.com.pem ssl_key = </etc/ssl/os/key-imap01-example.com.pem ssl_require_crl = no userdb { args = /etc/dovecot/mysql.conf driver = sql } root@imap01 [~]#

Change dovecot hostname
by Scott W. Sander 25 Aug '16

25 Aug '16

I have noticed that the name of my private server running dovecot appears in email headers rather than the public-friendly name of my server. Is there a method to specify an alternate server name for the dovecot server to use for itself in the dovecot configuration files? I performed a few Google searches and was not able to find the answer to my question. ------- user@server1:~$ dovecot --version 2.2.9 user@server1:~$ dovecot -n # 2.2.9: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-77-generic x86_64 Ubuntu 14.04.4 LTS ext4 auth_mechanisms = plain login info_log_path = /var/log/dovecot.log log_path = /var/log/dovecot.log mail_location = maildir:/var/mail/vhosts/%d/%n 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 { args = scheme=PLAIN username_format=%u /etc/dovecot/dovecot-users driver = passwd-file } protocols = " imap lmtp pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } } service imap-login { inet_listener imaps { port = 993 ssl = yes } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } ssl = required ssl_cert = </etc/ssl/certs/server1_combined.pem ssl_key = </etc/ssl/private/server1_key.pem userdb { args = uid=vmail gid=vmail home=/var/mail/vhosts/%d/%n driver = static }

Possible IMAP IDLE bug in Dovecot 2.2.18 and 2.2.25
by cleber-listas＠inetweb.com.br 24 Aug '16

24 Aug '16

Hello Guys, I guess that I found a bug in Dovecot 2.2.18 and 2.2.25 versions. The problem it's when I try to connect in a Dovecot used a proxy to another e-mail server (in our case it's a Smartermail Server) the DoveCot send a lot of IDLE commands to the destination server. With that, the LOG files grow and grow and grow :( I make a test with 1 connection only and if you see the log file in the same second the dovecot send 25, 40 IDLE commands. But, when I disconnect the client (outlook 2013) the dovecot continue to send the IDLE command for some seconds. If I try to connect directly to Smartermail with Outlook this don't occurrs.

antispam plugin pipe script seems not to be called when it "should be"
by Ben Johnson 23 Aug '16

23 Aug '16

Hello, (Full "doveconf -n" output is at the end of this message.) I'm attempting to recreate a "recipe" I had used successfully for quite some time (in Ubuntu 12.04 LTS), which allowed me to train SpamAssassin's Bayes database when someone dragged an email message from one sub-folder of the account to another. I later tried to re-implement it (in Ubuntu 14.04 LTS), and core-dumps resulted. I posted to this list about it several times, but nobody was ever able to help me solve the problem. I just tried the same (in Ubuntu 16.04 LTS), hoping that the source had evolved since then, and while I don't see a core-dump, the pipe script doesn't seem to be called. I've booby-trapped the pipe script with quite a bit of debugging output, which should be written to a file, but I don't see any indication that the pipe script is ever executed. When logged-in as an IMAP user, and I drag a message from the user's Inbox into the "Spam" folder, I do see the following activity in the syslog: Aug 18 22:12:15 example.com imap: antispam: mailbox_is_unsure(Junk): 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_trash(INBOX): 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_trash(Junk): 0 Aug 18 22:12:15 example.com imap: antispam: mail copy: from trash: 0, to trash: 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_spam(INBOX): 0 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_spam(Junk): 1 Aug 18 22:12:15 example.com imap: antispam: mailbox_is_unsure(INBOX): 0 Aug 18 22:12:15 example.com imap: antispam: mail copy: src spam: 0, dst spam: 1, src unsure: 0 Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program /bin/bash Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program /bin/bash Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program parameter 1 /usr/local/bin/sa-learn-pipe.sh Aug 18 22:12:15 example.com imap: antispam: running mailtrain backend program parameter 2 --spam But the piped message is never delivered to the target mailbox.

Postfix uses the filename you provide as name for the db file, so running it against symlinks does follow the symlink, but it uses the symlink name as what it uses to create the .db file. You can test this by creating file and doing symlink for it and running postmap against the symlink. You'll see that it will create symlink-name.db file instead of file.db. Aki Tuomi Dovecot oy

Oh yeah, right, LMTP. I don't run LMTP myself, but I suspect the hostname is mapped from the IP of the LMTP listening interface (using /etc/hosts or DNS). Maybe you can change the IP of your listening interface to match mail.domain.test and firewall it off if that IP is public facing. >From reading the code, I can't quite grok how LMTP derives the host label, but as a last resort, you can patch at src/lmtp/commands.c in client_get_added_headers().

specifying elliptic curve

Hi, I've noticed that Dovecot is using per default the elliptic curve sect571r1. Because not all clients might support sect571r1, I would like to set the elliptic curve manually. Is that possible? -Ihsan -- ihsan(a)dogan.ch http://blog.dogan.ch/

Crash on opening mailbox
by Ladislav Laska 22 Aug '16

22 Aug '16

Hi! I'm currently experiencing a crash of dovecot 2.2.25 on Gentoo, upon opening mailbox. The crash only triggers on opening inbox, other mailboxes seem to work fine. It happens every time, and can be reproduced on request. I also briefly tried 2.2.19, and it behaves the same. The bug seems to be triggered by some mail, as I encountered it previously and fixed by removing some spam. I guess it might be malformed header of some kind. I can open the mailbox locally using mutt, but fail to do so remotely (using mutt or K-9 mail on android). Unforunately, I haven't been able to isolate the specific mail, as when I create a new mailbox, dovecot refuses to open it: [CANNOT] Mailbox isn't a valid mbox file (0.000 + 0.000 secs). I'm not really sure what's going on and will investigate further once I find some time to do so. I also experienced a similar problem on opening a specific mail, but it's much harder to reproduce and I currently don't have an example. The crash looks very similar, and only happens on first attempt to open a specific mail, it always works later on. I'm attaching a stack trace and dovecot -n. I'm also willing to send the binary and core dump, but not publicly, as I'm not eager to share whatever's inside with the whole world. Other than what I mentioned, I'm running pretty standard setup, with postfix on Gentoo x86_64, ext4 fs, quota and disk space is plentiful. The delivery agent is dovecot itself, in postfix/main.cf I have: mailbox_command = /usr/libexec/dovecot/deliver I'm using sieve script to file my mail, but the problem manifested even before when I was still using procmail to deliver my mail (I migrated because I had doubts about procmail and dovecot lock cooperation) I'll keep my mailbox corrupted for a few more days, and access the mail only locally, hoping to test a potential fix. Let me know if you need any more info/experimentation. Also, if you know a good way to find the mail that causes the trouble out of the core, let me know, I'd be glad to forward it for testing. Thanks and I hope we can find (and fix) the problem! -- S pozdravem Ladislav Láska <laska(a)kam.mff.cuni.cz> Katedra Aplikované Matematiky, MFF UK tel.: +420 739 464 167

LMTP doing passdb queries ?
by Peter Mogensen 22 Aug '16

22 Aug '16

Hi, I can see dovecot is doing a passdb query when handling the LMTP RCPT command. That's kinda unexpected for me. I would have thought it only did a userdb lookup. I have disabled lmtp_proxy to be sure it didn't do a passdb lookup to check the proxy field. Is this expected? Doesn't the LDA only do userdb lookups? /Peter

Catch-all with LMTP and Postfix

Hidy-ho, I'm having a difficult time getting catch-all working when using Dovecot LMTP.

Field Return-Path contains twice the domain
by Quaquaraquà 21 Aug '16

21 Aug '16

Dear exim & dovecot users, posting on both mailing lists as I am not sure who has the ultimate responsability for this field. I am trying to set up a mail server for multiple domains in my VPS. So I managed to set up the authentication through a dovecot authenticator, which relies to a sqlite database. I would like that, from the database perspective, a query has, as input parameters, both the username and the domain to check the password. For this purpose, I am requesting that the SMTP account is in the full form username(a)domain.com. When forwarded to the dovecot authenticator, I can extract the user with %n and %d. This works, but it has a utter drawback: emails are sent repeating twice the domain in the Return-Path field, e.g. : Return-Path: <"user(a)domain.net"@domain.net> Subject: Re: Hello To: nuquaquaraqua(a)gmail.com From: user <user(a)domain.net> How do I properly fix the field Return-Path now? dovecot --version: 2.2.25 (7be1766) Exim version 4.87 #1 built 28-Jul-2016 18:38:04 Kind regards, Quaquaraqua

Occasional error from TB when selecting a dovecot's shared mbox: "Unable to open the summary file for [shared]" "Perhaps there was an error on disk, or the full path is too long." The server's disk is clear, and the longest full path is [a-zA-Z\/\.]{46}. The error occurs occasionally.

What might cause messages delivered with dovecot-lda to be "invisible" to IMAP clients?
by Ben Johnson 19 Aug '16

19 Aug '16

Hello! I'm attempting to use dovecot-lda, and for whatever reason, messages that I send with it are not visible in my IMAP client. $ dovecot --version 2.2.22 (fe789d2) (Full "doveconf -n" output is at the bottom of this message!) Here's the the sequence of commands that I'm using: # su vmail $ echo 'This is a test message.' > /tmp/test.txt $ stat /tmp/test.txt File: '/tmp/test.txt' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:49:38.419011552 -0400 Modify: 2016-08-18 20:49:07.178995015 -0400 Change: 2016-08-18 20:49:38.191011425 -0400 Birth: - $ /usr/lib/dovecot/dovecot-lda -d "test(a)example.com" -p "/tmp/test.txt" When I do this, the destination mailbox acts like there's a new message (I'm using Thunderbird, and the mailbox is highlighted in blue and bolded, which is the "new mail" behavior in this client). But when I "check my inbox", i.e., click on the Inbox, I don't see the new message. With regard to the filesystem, the message is present and contains the intended contents. Here's the "stat" output: $ stat /var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2, File: '/var/vmail/example.com/ben/Maildir/cur/1471567777.M685753P32257.example.com,S=24:2,' Size: 24 Blocks: 8 IO Block: 4096 regular file Device: fd01h/64769d Inode: 783925 Links: 2 Access: (0664/-rw-rw-r--) Uid: ( 5000/ vmail) Gid: ( 5000/ vmail) Access: 2016-08-18 20:51:05.647059340 -0400 Modify: 2016-08-18 20:50:58.543055378 -0400 Change: 2016-08-18 20:50:58.543055378 -0400 Birth: - Might anyone know why I'm not "seeing" this message in my IMAP client?

Reporting on CephFS being ready to use with Dovecot
by Daniel van Ham Colchete 18 Aug '16

18 Aug '16

I would like to report that from version 10.2.3 on (next release), Ceph FS is working really well with Dovecot systems. For those that don't know, Ceph is a "distributed object store and file system designed to provide excellent performance, reliability and scalability.". We have used it here since 2013 very successfully, but never with our Dovecot setup. For more information go on http://ceph.com/. Since Ceph Jewel (the current version), Ceph FS is considered production ready by their team. With Ceph FS you have a cache-coherent POSIX-compliant [1] clustered file system, without most of the NFS shortcomings. Ceph have very nice features like online upgrades, online maintenance, constant deep scrubbing of replicated data, cache tiering (HD -> SSD -> etc), erasure coding (clustered RAID6 for really old email - I'm not using), etc. Ceph is very complex to operate but very flexible and robust. This year we moved our Dovecot servers to a Ceph based system, found one bug there (http://tracker.ceph.com/issues/15920) when Dovecot's LMTP was delivery an email, and the fix is about to be released on version 10.2.3. I have been using a fix-build here for a couple of months without issue. So, now I'm glad to share with you guys that it works really well! My setup involves two clusters, each with about 30k-40k users. Each cluster will have two HD storages (with 6TB HDs), two SSD storages (with Intel 480GB SSDs) and two frontends. In a few months will add a third server of each type. Clusters work better with 3's. Here we used mdbox as it is better performant on Ceph for maintenance tasks, since each file is an object on Ceph and maintenance costs increase with the number of objects. We created two base directories: - /srv/dovecot/mail/%d/%n - stored on HDs with the most recent files cached on SSDs, thanks to Ceph Cache Tiering. Also, the directory structure itself is stored on SSDs, so dir listings are very fast (Ceph FS Metadata). - /srv/dovecot/index/%d/%n - stored only on SSDs, thanks for Ceph FS file layout. On our setup about 17% of the IOPs are going to HDs, the rest will go to SSDs, even though SSDs are less than 5% of the space. This is a matter of tuning the cache tiering parameters, but we didn't look at that yet. That setup is working like a charm, performance is about 53% better than when we were using NFS on the same hardware. Our previous DRBD+Heartbeat setup didn't allow for online maintenance and had a few problems. Now we can do 100% online maintenance on storage without users noticing, and on frontends with just a reconnect but without any downtime. Ceph is hard to learn at first but those with bigger setups and stronger SLAs will want to take a look at that. I really recommend that the Dovecot community take at look at that setup. Good luck! Best, Daniel Colchete [1] http://docs.ceph.com/docs/hammer/dev/differences-from-posix/

POP3 strange logging behavior after upgrade from 2.2.13 to 2.2.25
by Iavor Stoev 18 Aug '16

18 Aug '16

Hello, After the upgrade from Dovecot version 2.2.13 to 2.2.25, we experience the following strange behavior with POP3 logging. When a connection is closed with reason "Connection closed" & "Disconnected for inactivity", the number of deleted mails is missing. Like del=/1166 & del=/4138 from the example bellow. With Dovecot 2.2.13: Feb 14 03:35:20 serverXYZ dovecot: pop3(user(a)domain.com): Connection closed top=0/0, retr=0/0, del=0/946, size=39500197 Feb 15 16:49:18 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected for inactivity top=0/0, retr=0/0, del=0/739, size=52319632 With Dovecot 2.2.25: Jul 31 02:56:03 serverXYZ dovecot: pop3(user(a)domain.com): Connection closed top=1/1380, retr=0/0, del=/4138, size=284167741 Jul 31 02:34:47 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected for inactivity top=0/0, retr=0/0, del=/1166, size=111425436 For sessions completed normally, everything works fine with both Dovecot versions: Jul 31 06:55:48 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 Jul 31 02:36:59 serverXYZ dovecot: pop3(user(a)domain.com): Disconnected: Logged out top=0/0, retr=1/18821, del=1/1, size=18803 Please advise if this behavior is normal and if yes how should we read entries like "del=/4138"?

dsync replication issue
by Cédric ML 18 Aug '16

18 Aug '16

Hello, I'm facing a problem with dsync : replication between my two dovecot 2.2.10 servers (10.10.10.10 = serverA and 10.10.10.11 = serverB) is not done when a mail is received on any of the two servers. Sync is correctly working when running "doveadm [-D] sync -A tcp:10.10.10.10:12345" from serverB or "doveadm [-D] sync -A tcp:10.10.10.11:12345" from serverA Sieve vacation message replication is functional too, and triggered when a change is done on any of the two servers. I guess it's a notify problem, but I did not find how to debug it... I've enabled dovecot debug, but I don't see anything related to notify in logfile. Here's my doveconf -n (it's the same on the two servers, except IP address changes) Hope somebody will be able to help me.

dsync: Keywords not being replicated

I just noticed that some IMAP keywords are not being replicated through dsync backup/sync using Dovecot 2.2.24 from Debian backports: On the master server everything looks fine: RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered) - ext 0 keywords : (0900) <-- 0900 - ext 1 modseq : 701695 (ffb40a0000000000) - ext 3 cache : 3948 (6c0f0000) - ext 4 sort-s : 0 (00000000) On Replica: RECORD: seq=3, uid=44731, flags=0x09 (Seen Answered) - ext 0 keywords : (0000) <-- 0000 - ext 1 modseq : 701695 (ffb40a0000000000) - ext 3 cache : 3948 (6c0f0000) In this case the "forwarded" keyword is gone. Thunderbird no longer displays the message as having been forwarded. The command I used was: > doveadm sync -u myuser -l 60 -N tcp:replica:24245 My config is attached.

[Dovecot] How to disable SSL and TLSv1.1?
by Darren Pilgrim 16 Aug '16

16 Aug '16

I'm running Dovecot 2.2.5 and want to make it refuse SSLv2, SSLv3 and TLSv1.0. Clients will opportunistically use TLS 1.1 and 1.2, but now I want require they do so. Is it enough to set ssl_cipher_list = HIGH:!SSLv2:!SSLv3:!TLSv1.0:!aNULL:!MD5 or are there additional settings I need to specify?

public namespace quota
by Chris 15 Aug '16

15 Aug '16

All, sorry, I've to ask again. I'm trying to define quotas for public namespace subfolders: ns=public/ - DepartmentA - 50G - DepartmentB - 500M - DepartmentC - 10G public/ shouldn't have a limit. public/DepartmentA is independent of B and C. Is this possible with dovecot? I've added the following rules quota = maildir:User quota quota2 = maildir:Public quota:ns=public/ quota2_rule = *:storage=10M quota2_rule2 = DepartmentA:storage=+50M but then only 10M is shown for DepartmentA in Thunderbird. I'm using Maildir++. maildirsize is only created in public/ toplevel, not in public/DepartmentA. Public-subfolders are owned by vmail system-user. Different virtual users' ACLs are set (and working). Any help is appreciated! - Chris

Symbolic link for sieve script not created by dsync
by Laz C. Peterson 15 Aug '16

15 Aug '16

Hello Dovecot ~ I know this bug has been discussed previously for other versions of dsync, pigeonhole and dovecot … But we still can’t get dsync to create the symbolic link for the sieve script after it is created on a replicated server. We are running Ubuntu 16.04.1 with the official Ubuntu dovecot packages (2.2.22). Sieve script itself is replicated, but not the symbolic link. Any suggestions? ~ Laz Peterson Paravis, LLC

fts-solr autoindex issue in public mailbox
by maks 15 Aug '16

15 Aug '16

Hello everyone, I have a public mailbox: /var/mail/example.com/public/public_mailbox with "Public/" namespace set up in config file. When i move message from user's INBOX to one of mailboxes inside Public/ (for example Public/archive), i'm getting "indexer-worker: Info: Indexed 0 messages in Public/archive" in logs and i can't find the message through the FTS search. If i move the message back from Public/archive into personal mailbox the message is indexed by indexer-worker "indexer-worker: Info: Indexed 1 messages in temp_folder" If i perform "doveadm index Public/archive" then the message is added to the index. Dovecot version: 2.2.9 FTS backend: Solr fts_autoindex = yes Searching through localhost:8983/solr/collection1 gives the same result.

Bug with shared access to mailbox
by van der Kamp, John 15 Aug '16

15 Aug '16

Hello, I'm testing dovecot with some setups, and one of them is with shared mailboxes. The test I wrote will create and delete mail using multiple connections to the same user and folder. Each connection makes a couple of mails, remembers the uid from APPENDUID, and will delete those emails again. At the end of the test I expect an empty folder. This is not what happens. At the end I still have several mails in the folder. I lack insight in the dovecot source to tell exactly what's going on. I've tested this with different setups: 1) local system user, connecting over localhost -> bug is present 2) local system user, connecting over internet -> bug is present, but is harder to reproduce 3) dovecot as proxy to another imap server -> bug is present In step 3, you can even setup a dovecot to be a proxy to another dovecot server. >From logging in the other imap server I've seen that a client command to the proxy like: TAG UID STORE 1:3 +FLAGS (\Deleted) TAG UID EXPUNGE 1:3 will be sent to the other imap server in 3 steps, one for each message. When running the test with multiple threads, that logging shows that some uids are never sent to the other imap server, and some uids are sent over different connections than they original were sent to. (Thread 1 deletes 1:3, Thread 2 deletes 4:6, the proxy of Thread 1 might expunge messages from Thread 2 and vice versa). Attached is a python script which tests the behavior. The script expects a file named "testmail.eml" to upload to the imap server. I used an email which was about 75 kB. I tested using version: 2.2.22 (fe789d2). Let me know if I can help in any other way too. John

Save user passwords in clear text

Is it possible to save user passwords as clear text through dovecot? I am currently using MD5 passwords and I allow only "plain and login” mechanisms but I want to switch my database to clear text as this will give me the ability to use more mechanisms such as CRAM-MD5. Is this possible? Thank you

receiving and associating emails to single a/c
by David Tildesley 12 Aug '16

12 Aug '16

Hi,Looking for advice.Scenario: we have a dmz mta that currently redirects received emails for a selection of email domains to specific internal ms exchange servers. We want this mta to redirect incoming customer emails directed to a set of email addresses numbering about 30, to a dovecot server and associate these emails to a single dovecot user account so that a contact Centre platform can pull these emails on a frequent cycle.How to go about configuring this on the dovecot? I assume a postfix server needs to be installed on the dovecot server for the dmz mta to send these emails to dovecot inbox? Any advice most appreciated. David. Sent from Yahoo Mail on Android

Dovecot Director self ip
by Tomaž 12 Aug '16

12 Aug '16

Hello everybody! I kindly ask somebody to help me with this problem. I'm trying to configure Dovecot proxy with Director. On the same machine is KeepAlived that needs this configured to bind non local IP: sysctl net.ipv4.ip_nonlocal_bind=1 But as already mentioned in this email: http://www.dovecot.org/list/dovecot/2012-November/087033.html Dovecot Director needs sysctl net.ipv4.ip_nonlocal_bind=0 (if this is set, everything works ok, but we break keepalived) because otherwise the second server uses IP from the first server as "self". Is it possible to configure this some other way, so Dovecot Director doesn't try to bind to all IPs and because of above configuration, uses the first one that binds. This is the result from director status on server 1: root@u1:~# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never handshaking and server 2: root@u2:/var/log# doveadm director ring status director ip port type last failed status 172.16.100.191 9090 self never handshaking 172.16.100.192 9090 never My dovecot config: http://pastebin.com/RnmHRWhY Thank you very much!

dovecot 2.2.25 & deleting emails from \Junk special-use assigned folder

Since our cPanel installation upgraded Dovecot from 2.2.23 to 2.2.25, deleting emails located in the Junk folder (\Junk special-use), the emails end-up in the \Trash special-use folder instead of being purged as before. Is there something that changed or this some configuration I am missing? Thanks for any help regarding this. -- Marc Jauvin Register4less, Inc. 514-905-6500 x403

custom mail_location detection for dovecot lda
by Alexander 'Leo' Bergolth 09 Aug '16

09 Aug '16

Hi! Is it possible to do something like "post-login scripting" to detect and set a per-user custom mail location for dovecot LDA delivery? I tried to use a wrapper-script around dovecot-lda that sets the environment variables MAIL="..." and USERDB_KEYS="MAIL" just like overriding userdb fields may be done using imap postlogin scripts, but unfortunately this doesn't seem to be honored. (Also tried with dovecot-lda -k.) Woud be very useful for slow migration from one mailbox format to another. Is there any other way to supply a custom mail_location to dovecot-lda?

Questions about how fts-solr works
by Radu Gheorghe 08 Aug '16

08 Aug '16

Hello, I'm quite a Dovecot newbie, so please be gentle :) Though I did my homework as well as I could, I still have some questions regarding the Solr plugin. Specifically: - I understand that by default, a mailbox is indexed on the first search and then deltas are indexed in subsequent searches. Are Emails indexed in batches or one by one? Looking at the code, I see a hardcoded limit of 1000, and I'm guessing if the mailbox is done and there are <1000 Emails in the buffer, it just flushes them, right? - if I set fts_autoindex=yes, does it mean that as soon as the Email is delivered by the MTA, it will be indexed in Solr? or does it have to read by the user or touched in any way? - also, with fts_autoindex=yes, are Emails indexed in batches? if yes, is there also a time limit besides the size limit? e.g. if only 100 messages were received - I have the same question about deletes: when do they happen, and are they batched? - what happens if Solr is unavailable? I know Dovecot keeps track of what indexed in dovecot.indexed files, but does it retry? if yes, what's the retry policy and can it be configured? Also, does it behave the same if Solr is actually available and throws an error? - the same question is for attachments, though I think this is general FTS - what if Tika fails to parse the attachment? Does Dovecot still index the Email metadata? As a side, I'm also wondering if I could use the Tika that comes with Solr (https://cwiki.apache.org/confluence/display/solr/Uploading+Data+with+Solr+C…) Can fts-solr handle attachments at all? I'm asking because I don't see that field in the default schema.xml - can I add arbitrary URI parameters to the Solr request? I see that one could fiddle with the path, which I assume will let one have one collection per mailbox (though I'm curious how that works with batches - I'm guessing one batch/indexing thread per mailbox?). Specifically, I'm interested in using the mailbox as a routing value - if I read the code well, Dovecot does a soft commit when it's done with the specific mailbox. For indexing at search time, I see why it makes sense. If I do "autoindex", can I disable that and let Solr autoSoftCommit every N seconds? That should improve indexing throughput and reduce load. I see that one can already do this for hard commits (I'd use autoCommit there, though a hard commit is also triggered when ramBufferSizeMB gets hit) - when querying, can I sort by an arbitrary field, such as the date? I saw I can sort by score, but I can't find anything in the code that will suggest it's supported - also when querying, can I specify which fields to return? I see that the plugin asks for Email ID, so I'm guessing it fetches things like from/to from the Email itself. I'm thinking that if I want to sort by those values I need to set docValues=true on them, to save memory. In that case, I might as well retrieve the original string from docValues, which should be a whole lot faster My plan is to do all sorts of tests, but having a better background on how it works will certainly help. Any pointers, feedback, encouragement, etc is certainly welcome - thanks in advance!

Dovecot password policy
by Robert Blayzor 06 Aug '16

Is there a way to configure Dovecot to perhaps filter/enforce which passwords are accepted before authenticating? Ie: Reject immediately (without a database lookup) if password is not X characters in length? ? -- Robert inoc.net!rblayzor XMPP: rblayzor.AT.inoc.net PGP Key: 78BEDCE1 @ pgp.mit.edu

Yes, use the checkpassword hook. http://wiki.dovecot.org/AuthDatabase/CheckPassword I think there also some PAM module that you can stack into your system that will enforce password policies.

Dovecot and Solr 6
by KSB 05 Aug '16

05 Aug '16

Hi! Dovecot 2.2.24 Had set up solr and new schema collection. Copied dovecot provided schema. There was an error with booleans (while getting schema via http), which I "solved" by removing "add-unknown-fields-to-the-schema" from solrconfig.xml. It is correct way to solve this? Anyway, I run tcpdump to see network activity between dovecot and solr: #tcpdump -i lo port 8983 and see nothing while doing: #doveadm fts rescan -u username(a)domain.tld no output also from doveadm. Noticed that dovecot.index.log reapears in user mail root if deleted. plugin { fts = solr fts_solr = url=http://localhost:8983/solr/dovecot/ debug .. } -- KSB

Problem with sieve configuration on dovecot+debian_jessie+ISPC3
by Filip Loncar [WarpMax | FederationServers] 05 Aug '16

05 Aug '16

I'm new-ish to dovecot and sieve (haven't used it extensively till now) and I'm not sure that I configured everything propperly. The problem is that we're trying to get the following sieve code to run: require ["fileinto", "regex", "date", "relational", "vacation", "duplicate"]; require "duplicate"; if duplicate :header "message-id" { discard; } else { redirect "<somemail1>"; redirect "<somemail2>"; redirect "<somemail3>"; redirect "<somemail4>"; redirect "<somemail5>"; redirect "<somemail6>"; keep; } keep; But we're constantly getting the following error: sieve: info: started log at Aug 02 08:13:21. main script: line 5: error: require command: unknown Sieve capability `duplicate'. main script: line 6: error: unknown test 'duplicate' (only reported once at first occurence). main script: error: validation failed. Both me and my collegue can't find what's wrong with the system. I would appreciate any kind of help on this matter.

New password hashing scheme as plugin
by Andreas Meyer 05 Aug '16

05 Aug '16

Hi, I want to add a new password hashing scheme as plugin and provide it for the dovecot project, so that it will be included as optional plugin in future releases. Yet the plugin compiles fine and the .so file gets created. My approach is to call the functions password_scheme_register() and password_scheme_unregister() (src/auth/password-scheme.c) inside the plugin's _init() and _deinit() functions. When a client tries to login via imap the log shows an error message: Error: Couldn't load required plugin /usr/local/lib/dovecot/lib20_newauth_plugin.so: dlopen() failed: /usr/local/lib/dovecot/lib20_newauth_plugin.so: undefined symbol: password_scheme_unregister That error obviously occurs, because the required lib is not linked into the plugin. Now my problem is to understand, whether this approach (via .so file) can be successful at all and if so, how? Do I need to link libs into it? Which would that be and how do I specify them in the Makefile.am? I assume, I don't need to link a lib, but need to use a hook to register the new hashing scheme, since the plugin is loaded into an already existing process, which needs to get extended. If this is true, which hook would that be and how do I register the new scheme? Or is there no way to accomplish this via a separated .so plugin? Should I extend the sources in /src/auth instead? (separat file for the hashing scheme with preprocessor instructions to include it only on demand) Thank you very much, Andreas

file/folder perms permissions
by Jim Pazarena 05 Aug '16

05 Aug '16

Forgive me if I am blind, but I cannot find default folder permissions. For the home directories, with the sub of mail: and deeper, I see some files with 660, some with 600, some folders with 770 some with 660 I am a bit confused. I manually messed with some files, and my MUA complained about permissions. So I got that mess fixed, and in doing so I noticed the seemingly contradictory permissions. Thanks!

SSL connection reset by peer
by Vince42 04 Aug '16

04 Aug '16

Hi, I am running a dovecot server and have set up an external monitoring, where every five minutes a login with SSL on port 993 is done. I usually get once a day an error "connection reset by peer - SSL connect", which goes away until the next monitor is executed. Initially I thought that raising the mail_max_userip_connections in protocol imap in 20-imap.conf to 256 should do the trick - but the error stays. What could be the reason for this error and which configuration values could be changed in order to avoid this error? I read a lot of different suggestions - but did not find a plausible explanation and recommendation.

Attachment Storage problems
by Daniel van Ham Colchete 04 Aug '16

Guys, I started using single instance attachment storage a while ago but I had too many problems with it. My logs are filled with errors like: Aug 03 18:41:38 imap(user@domain): Error: read(attachments-connector(zlib(/srv/dovecot/mdbox/domain/user/storage/m.2))) failed: read(/srv/dovecot/attach/domain/5f/03/5f03f1d7da846fe9268473cae5219ae31019fd540dc67f58596d8390be4a0f2256158b1e9ba327841c513a6d927dbe9b767b7ad94f8ae5772674cccb3124b69d-7be2ef0e97036457c52000009331bd36[base64:19 b/l]) failed: open(/srv/dovecot/attach/domain/5f/03/5f03f1d7da846fe9268473cae5219ae31019fd540dc67f58596d8390be4a0f2256158b1e9ba327841c513a6d927dbe9b767b7ad94f8ae5772674cccb3124b69d-7be2ef0e97036457c52000009331bd36) failed: No such file or directory (uid=23484, box=INBOX) The funny thing is that the directory /srv/dovecot/attach/domain/5f/03/ doesn't even exist! So, I would like to stop using it and my question is: how? First we would need to stop writting things there while still reading it. How can I tell dovecot to stop using it on new e-mail? Second would be a dsync-like migration reinserting the attachments on the messages back. How can I do that? Most importantly, what do I do with the messages that lost attachments? Thank you very much. Best, Daniel Colchete

service-specific userdb affecting lmtp, quota-service
by Michael Fox 03 Aug '16

The service specific passwd-file userdb is causing quota-status and lmtp to fail. Using: userdb { args = ... /etc/dovecot/auth.d/%d/userdb.%s } I'm getting the following in /var/log/mail.err when I try to send/receive mail: Aug 1 15:46:57 n6mef-gw dovecot: auth: Error: passwd-file(mefpop(a)email.n6mef.org): stat(/etc/dovecot/auth.d/email.n6mef.org/userdb.quota-status) failed: Address family not supported by protocol Aug 1 15:47:08 n6mef-gw dovecot: auth: Error: passwd-file(mefpop(a)email.n6mef.org): stat(/etc/dovecot/auth.d/email.n6mef.org/userdb.lmtp) failed: Address family not supported by protocol I don't have a userdb.quota-status or userdb.lmtp.

"Plaintext authentication disallowed on non-secure (SSL/TLS) connections" despite correct configuration to allow this
by Christian Balzer 03 Aug '16

03 Aug '16

Hello, this is basically a repeat of this query from last year, which unfortunately got a deafening silence for replies: --- http://dovecot.org/pipermail/dovecot/2015-August/101720.html --- I have mostly 2.1.7 (Debian Wheezy) mailbox servers and the current proxies are also of that vintage. So with "ssl=yes" and "disable_plaintext_auth=no" plaintext logins work, as per the documentation (http://wiki2.dovecot.org/SSL/DovecotConfiguration) and historically expected. Trying to use a 2.2.24 (Debian Jessie backports) dovecot proy with the same parameters fails like this: --- Aug 2 15:45:57 smtp12 dovecot: pop3-login: proxy(chibixxx(a)gol.com): Login failed to mbxx.xxx.gol.com:110: Plaintext authentication disallowed on non-secure (SSL/TLS) connections.: user=<chibixxx(a)gol.com>, method=PLAIN, rip=x.x.x.x, lip=x.x.x.x, pid=16066 --- Changing things to "ssl=no" doesn't help and setting trusted networks only changes the last bit to have "secured" appended but still fails the same otherwise. I really need 2.2.x to behave the same way as before and documented. Any ideas and feedback would be most welcome.

Error: Timeout (180s) while waiting for lock for transaction log file dovecot.index.log
by Götz Reinicke - IT Koordinator 02 Aug '16

02 Aug '16

Hi, our maildir store is on a NFS share which was working fine for some time with the recommended setting from the dovecot wiki; suddenly today i got informed that one user has login problems to his mails and I have some messages in the logs: Error: Timeout (180s) while waiting for lock for transaction log file ....../Maildir/dovecot.index.log My current guess is a hick up in the network during a router configuration this weekend. My question: How to solve the problem? I can restart the nfs service/server later this day, as well as the mailserver ... as there is a kernel update too. Do I have to initiate some resync or deletion of index or whatsoever files? Thanks for any feedback and regards . Götz

passwd-file extra-fields: inbox=yes
by Michael Fox 01 Aug '16

01 Aug '16

I'd like to implement the virtual plugin so that POP3 users can see emails in their own inbox and a public namespace. As I understand it, I need to set "inbox=yes" separately, depending on which service the user is using. With passwd-file flat files, this means: userdb { args = ... /path/userdb.%s } userdb.imap: set the extra fields for each user = userdb_namespace/inbox/inbox=yes userdb.pop3: set the extra fields for each user = userdb_namespace/virtual/inbox=yes But without even getting to the virtual namespace part, I'm having difficulty getting the extra fields setting to work for a regular IMAP user. Specifically: If I use the Dovecot default settings of namespace inbox, which includes inbox=yes, and do NOT include the extra_fields value shown above, then IMAP users can log in OK. But if I comment out inbox=yes within namespace inbox, and then add the extra fields to userdb.imap (as shown above), (and reload doveadm), then the IMAP user is no longer able to login. Thunderbird displays "Login to server ... failed." and I get the following in syslog (mail.err): Aug 1 13:56:13 n6mef-gw dovecot: imap(mefimp(a)email.n6mef.org): Error: user mefimp(a)email.n6mef.org: Initialization failed: namespace configuration error: Duplicate namespace prefix: "" Aug 1 13:56:13 n6mef-gw dovecot: imap(mefimp(a)email.n6mef.org): Error: Invalid user settings. Refer to server log for more information. I'm at a loss for what's wrong. Can someone help? Userdb.imap test entry and doveconf -n below.

IMAP flags and dovecot-keywords not working as expected
by Mark Foley 01 Aug '16

01 Aug '16

I've converted most of our users from Outlook to Thunderbird. One important feature of Thunderbird is that it pays attention to the IMAP non-standard message flags via the 'tags' feature (see http://wiki2.dovecot.org/MailboxFormat/Maildir) This is important because 2 users make extensive use of Outlook categories (Tags, in Thunderbird). I found that when I set a message to the 1st Tbird tag 0 (Important), the corresponding IMAP file got an 'a' suffix. Likewise, if I manually added an 'a' suffix to an IMAP file the corresponding tag was set displayed in Thunderbird. This made it easy for me to exports Outlook Categories and set IMAP messages flags accordingly. This worked perfectly on the user I was experimenting with (me). Recently, I converted one of these Outlook 'categories' users to Thunderbird. I added the appropriate flag letters to their IMAP messages, changed their tag names in Thunderbird, and created the following dovecot-keywords file as: 0 Board_and_Committee 1 Completed 2 Health_Care_meetings 3 Notifications 4 OSHP-DAS 5 personal_or_To_Do 6 Retirement_exits 7 $label5 8 Junk 9 $Forwarded 10 $MDNSent 11 $label2 However, none of the tags show up correctly in Thunderbird. If I manually set a message to have a tag of 0, the corresponding IMAP file gets a flag of 'm', not 'a' and the following is added to the dovecot-keywords files: 12 $label1 How can I fix this? Where is "$label1" text defined? Why did Thunderbird not snag the text for '0' from the dovecot-keywords file and give the IMAP file a tag of 'a'? My current theory is that the "Default" Thunderbird Tags corresponding to IMAP flags are not changeable and if new tags are create in Tbird, they get new flag letters. That would, of course, mean that if a user changes Thunderbird tag name, they would lose all tag settings on existing message. That doesn't seem right and I hope my theory is wrong. Any insight would be appreciated. --Mark

POP3 & IMAP inbox setting for virtual
by Michael Fox 01 Aug '16

01 Aug '16

Posted Monday 7/25. Haven't seen a response. Trying again: --- This is a noobie question, so bear with me if it's not worded correctly: Primary Requirements: 1) I'd like to have two namespaces - one private/per-user, and one public (visible by all logged-in users). The public mailbox(s) would be used to distribute information to all users. 2) I'd like both POP3 and IMAP users to see both namespaces. As I understand it, this requires the use of the virtual plugin for POP3, in order to create a virtual namespace which would mix together the private and public namespaces into one mailbox. I have read: http://wiki.dovecot.org/Plugins/Virtual https://sys4.de/de/blog/2013/02/11/dovecot-virtual-setup-mit-globaler-sieve- spamfilter-regel-fur-pop3-nutzer/ (via Google translation) The example uses a CASE statement in the MySQL userdb query. As I understand it, this is done to set which namespace contains the inbox: the private namespace or the virtual namespace -- depending on if the user is connected via the imap or pop3 service, respectively. Question: how do I accomplish the same goal (setting the proper namespace for the inbox) when using a passwd-file style flat file userdb? Thanks, Michael

self signed certs and dovecot imaps : howto? tlsv1 alert unknown ca

How do you setup dovecot to use a self signed cert? One server will be connected to the internet. One will be totally internal and have no runtime access to the internet. Getting the below error msg. Also, I think I have a TLS 1.0 and need a 1.2 cert?... Thank you.

migration from cyrus; seg fault at mail_namespaces_get_root_sep
by vstargben＠gmail.com 31 Jul '16

31 Jul '16

Hi all, I am currently trying to migrate from cyrus to dovecot on a new system. Though only few accounts, I decided to use the mdbox format. To convert I use cyrus2dovecot first, then I use dsync to import the mailboxes. For compatibility I set the namespace of inbox to prefix = INBOX. and separator = . (as described here: http://wiki2.dovecot.org/Migration/Cyrus http://wiki.dovecot.org/Namespaces) This works except that the clients (mutt and Thunderbird) show an additional folder/mailbox "INBOX" below the inbox. How can I fix that? Should I add a prefix during conversion and not change the namespace config? On disk, the subfolders are next to INBOX. Well, I then tried to set list = children instead of "yes" for namespace inbox. On login a segfault occurs with this setting. See the information and backtrace below.

Occasional lock timeouts on Linode VM with Dovecot Replication
by Reuben Farrelly 31 Jul '16

31 Jul '16

I've been seeing periodic entries in my dovecot logs like this: dovecot[3464]: dsync-server(kaylene): Error: Couldn't lock /home/kaylene/.dovecot-sync.lock: Timed out after 30 seconds: 3 Time(s) dovecot[3464]: dsync-server(reuben): Error: Couldn't lock /home/reuben/.dovecot-sync.lock: Timed out after 30 seconds: 1 Time(s) They occur several times per day, but don't appear to have any obvious cause and I am not aware of any problems this is causing. [They could be the cause of some reappearing UID type messages that also periodically are logged, but I can't be sure] They occur on a lightly loaded Linode VM, KVM Paravirtualised and with only local SSD disk storage. The VM is a Gentoo Linux VM running the latest kernels that Linode provide. I also saw this problem under Xen. The dovecot setup is a dsync replication between two hosts, there is about 150ms of latency between them. The host where I am seeing these messages on (lightning) is a dovecot replica of another system (thunderstorm). I am using Maildir storage. Thunderstorm sees the vast majority of the client side reads and writes and lightning just functions as a not-so-active replica. Thunderstorm is also a VM but on VMware (also on SSDs). This system has never had this problem. I've had this across many dovecot versions going back many months now so it's impossible to pinpoint when this started. I am currently running dovecot -git master-2.2 branch at the moment. I've never seen disk latency in excess of 30s on any system either so I doubt that raw IO is the cause. I don't have any settings specified in 10-mail.conf in the Mail processes section relating to locking or mmap. Has anyone else experienced this and/or any ideas about where to look next to determine the root cause? Is this a common warning to see in cloud hosted/shared environments? Reuben

Master-Master replication question
by Remko Lodder 29 Jul '16

29 Jul '16

Dear list, I have setup a master-master replication setup. My primairy MX's send email over on a DNS loadbalanced way, so DNS is doing some kind of round-robin way of sending mail to both master servers. I found out, that on one of the two machines, the email synchronisation is heavily delayed. Lets assume server A receives a mail from the MX; it synchronises almost instantly with the other server. Whenever server B receives the email, it could take up to several hours to synchronise the email, it seems that it is not detected prior. It is also interesting to see, that the mailboxes on server A (Where users login to retrieve their email via webmail/clients) are significantly smaller then the mailboxes on server B. When investigating, it seems that "older" mailboxes (or storage rather since we use mdbox) are still there on server B, which already had been removed on server A. My personal mailbox was 170MB on server A, while it was still 2.5GB on server B. (which was around that size before cleaning up the mailsboxes). I enabled debugging on the servers, and I see rather quick : "Replication requests" on server A, but when getting an email on server B, I do not see the request at all. My servers are both running the same version, same configuration (utilizing puppet), both running on ZFS and FreeBSD. Where server B is more loaded in it's memory because of some bhyve VM's and the server A does not run any VM. Does someone have any pointers on where to look? Thanks in advance ;-) Remko Included below the configurations from server A and B: Server A: # 2.2.25 (7be1766): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.4.14 (099a97c) # OS: FreeBSD 10.3-RELEASE-p2 amd64 auth_mechanisms = plain login disable_plaintext_auth = no doveadm_password = #

The result is: ?The identify of > server 45.56.81.181 cannot be verified. The certificate for this > server is invalid.? Well, yes, that's what you would expect. You've told your mail client to connect to "45.56.81.181", the client starts the SSL negotiation and finds the certificate is made out for "sheepsystems.com", and your mail client complains about the mismatch (a possible MITM attack). This is what you want SSL enabled system to do. Since 45.56.81.181 does not map to "sheepsystems.com" yet, you can short-circuit DNS and add a direct mapping to your Mac by adding this to /etc/hosts: 45.56.81.181 sheepsystems.com then reconfiguring your mail client to use the server "sheepsystems.com". This will appease the SSL constraint. > appear in /var/log/mail.log [2]. Don't know what this is about -- probably your Mac bailing out on authentication. Joseph Tam <jtam.home(a)gmail.com>

Client app says my chained Comodo cert is invalid
by Jerry Krinock 27 Jul '16

27 Jul '16

I’ve configured Dovecot and Postfix on a new VPS running Ubuntu 16.04, using Linode’s tutorial [1], to require authentication and SSL encryption for both POP3 and SMTP. All looks OK to me except, when my email client app (macOS Mail.app) tries to log in, it says that my cert is invalid. The trouble appears when I attempt to configure a client account in Mail.app on my Mac. For the POP server name, I enter my VPS’ “45.56.81.181", because public DNS is still pointing to my existing host. I set the account to use the Apple TLS certificate, and then click to save this new account info. Before saving, Mail.app checks my entries by attempting to log in. The result is: “The identify of server 45.56.81.181 cannot be verified. The certificate for this server is invalid.” At the same time, on my new server, some entries appear in /var/log/mail.log [2]. The certificate in question is a new PositiveSSL/Comodo cert I bought the other day. It works OK for serving web pages - I mean, on this same Mac, when I visit my under-construction site at https://45.56.81.181 in Safari or Firefox, I get the padlock icon and no warnings. Comodo gave me two two files, a “.crt” which contains my cert, and a “.ca-bundle.crt” which contains their certs. Per Dovecot documentation, I concatenated these into a “chained” file containing all 3 certs, starting with mine. In /etc/dovecot/conf.d/10-ssl.conf, I set ssl_cert = this “chained” file. I tried adding the two original cert files to macOS Keychain.app with “Always trust” but that did not help. Being new at this, I would appreciate any suggestions. My `dovecot -n` output is below [3].

Sieve vacation address problem
by Harald Leithner 27 Jul '16

27 Jul '16

Hi, it seams I have a problem with the vacation script. The problem is that the vacation answers to a address that is not listed in the sieve script. I checked the postfix master.conf which delivers to lda correct parameter. In the logfile you can see that that office(a)example.com received a message that get delivered to user(a)example.com (with the sievescipt) and to office(a)example.com (another user without script). The sieve script has the :addresses parameter only set to user(a)example.com Is something wrong with my setup? We use roundcube + sievemanage to create sieve scripts. Sievescript: ## Generated by Roundcube Webmail SieveRules Plugin ## require ["date","relational","vacation"]; # rule:[Urlaub] if allof (currentdate :zone "+0200" :value "gt" "date" "2016-07-22",

Opportunistic quota recalc
by Tom Sommer 27 Jul '16

27 Jul '16

I'm switching quota backend to redis (from maildir++), so all my current usages are reset. I get that I can do "doveadm quota recalc -A", but it takes forever (and auth processes time out/crash). It would make much more sense to recalc the usage on login if the current usage is unset. Is there no way to do a recalc-quota-on-first-login? Thanks. -- Tom Sommer

Converting mailboxes to UTF-8
by Артем Перекресний 27 Jul '16

27 Jul '16

Is any proven routine to migrate mailboxes from mUTF-7 to UTF-8 encoding? I've try to use doveadm list/mutf7/rename but have been stuck with nested inboxes. Say I have the next structure: INBOX INBOX.жыр INBOX.жыр.ядъ encoded for FS respectively as .INBOX .INBOX.&BDYESwRA- .INBOX.&BDYESwRA-.&BE8ENARK- When I've try to rename INBOX.жыр with doveadm mailbox rename -u me -s "INBOX.&BDYESwRA-" $(doveadm mailbox mutf7 -7 "INBOX.&BDYESwRA-") I've get the next: .INBOX .INBOX.жыр .INBOX.жыр.&BE8ENARK- Sure when I've try to rename .INBOX.жыр.&BE8ENARK- I've get a message that this is not a valid mUTF7-encoded string. So that is the question.

imap & pop3 using same mailbox with virtual plugin
by Michael Fox 26 Jul '16

26 Jul '16

This is a noobie question, so bear with me if it's not worded correctly: Primary Requirements: 1) I'd like to have two namespaces - one private/per-user, and one public (visible by all logged-in users). The public mailbox would be used to distribute information to all users. 2) I'd like both POP3 and IMAP users to see both namespaces. As I understand it, this requires the use of the virtual plugin to create a virtual namespace which would mix together the private and public namespaces into one mailbox. I have read: http://wiki.dovecot.org/Plugins/Virtual https://sys4.de/de/blog/2013/02/11/dovecot-virtual-setup-mit-globaler-sieve- spamfilter-regel-fur-pop3-nutzer/ (via Google translation) I don't really understand the example MySQL code (too much "..." for me to follow) in the above web pages. As I understand it (and I could be very wrong), the solution relies on a MySQL query to determine which namespace should have inbox = yes -- the private namespace or the virtual namespace -- depending on if the user is an imap or pop3 user, respectively. Question 1: How would this be done on a user-by-user basis if the userdb is a passwd-file flat file? Would it be something like this? -- Userdb extra fields for IMAP User: userdb_namespace/inbox/inbox=yes -- Userdb extra fields for POP3 User: userdb_namespace/virtual/inbox=yes Question 2: If I want to allow any user to use either POP3 or IMAP, then could I do it this way? protocol imap { namespace inbox { inbox = yes } } protocol pop3 { namespace virtual { inbox = yes } } Thanks, Michael

Dovecot cannot find mailboxes
by C. Andrews Lavarre 26 Jul '16

26 Jul '16

Edgar, thank you for your help: I have solved gaining access from a client (Evolution) via IMAP to the server: I can refresh, add folders, and delete folders. But I am still confounded, as IMAP does not see any mailboxes. Neither we from the command line (telnet, openssl, login, select) nor the system can find the mailbox, despite following FindMailLocation: telnet, openssl, login, then b select inbox * 0 EXISTS * 0 RECENT and postfix fails with 2016-07-23T21:22:37.312039-04:00 lavarre postfix/error[17088]: A8DA2C1BB2: to=<andy(a)privustech.com>, orig_to=<andy>, relay But the mailboxes do exist in /var/mail/vhosts/privustech.com/andy and we point to them in /etc/dovecot/users. doveconf -n is attached. ----- Two issues are: 1. file permissions and ownership 2. virtual versus system users 1. It appears that having the correct ownership and permissions on various files is critical (of course), but those parameters must also be included in the interior of the /etc/dovecot/user. So if you change permissions you also must change that file. For example, you said: i also noticed your certificate chain is broken. http://wiki2.dovecot.org/testinstallation I worked through this link, thank you. Changing permissions for the directories /var/mail/* to root:mail ($UID:$GID = 1000:12) and then changing /etc/dovecot/users correspondingly to user(a)privustech.com :{plain}actualpassword: 1000:12 ::/var/mail/vhosts/privustech.com/user now allows a normal login. and we can create a new folder (e.g., work) and delete it. However, this is at variance with http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall which says to set the ownership to vmail:vmail ($UID:$GID = 100: 5000). Doing so breaks dovecot. 2. The various links suggest that having virtual users is preferable to setting system users. The former do not require directories under /homebut they do require a directory in the mail system, which I have provided under /var/mail/vhosts. It also turns out that for virtual users you must include the domain (andy(a)privustech.com) Making that change allowed the success reported above. But despite that, we still cannot find the mailboxes on login. Any thoughts on how to have IMAP find the mailboxes (beyond FindMailLocation, which doesn't seem to work for me) would be most appreciated. Kind regards, Andy

postconf -n display error for "remote"?
by Michael Fox 24 Jul '16

24 Jul '16

Is this a bug? I configured the following: remote 192.168.7.128/27 { ssl = no } remote 192.168.7.0/24 { ssl = yes } But, when I run doveconf -n, I see: remote 192.168.7.0/24/24 { ssl = yes } remote 192.168.7.128/27/27 { ssl = no } Note the repeated network prefix length (/27/27 and /24/24). Is there a way to tell for sure whether this is just a cosmetic issue or something that could cause a problem? Michael

by C. Andrews Lavarre 24 Jul '16

24 Jul '16

Hello all. Thank you for your service. Easy when you know how, but presently I do not. After literally months of research and experimentation we simply cannot log into our PAM / apache2 / postfix / dovecot pop3/imap STARTTLS email server with an ordinary email client, e.g., Evolution or Thunderbird. We can connect to the host server in a host of different ways (no pun intended)—http, https, ssh, vnc, telnet, openssl -sclient Similarly we can connect to postfix and dovecot in yet another number of ways—telnet, openssl -sclient—but cannot log in to the email server with a normal email client (either Evolution or Thunderbird) by either pop3 or imap. SSL certificates are in place, verified, and tested. Part of the problem is the many changes in all the involved operating systems and protocols (e.g., imaps and pop3s are deprecated, openSUSE has migrated to LEAP, etc.) so many of the docs from Google are no longer valid. Additionally, there simply are bugs: Leap 42.1 YAST does not work when it comes to setting up websites. Documented. But I digress. I'm sure it's something really simple, but it evades me. Research details below. Any help would be more than appreciated. Thanks in advance, Andy ======================= Configuration testing details ======================= System is: Linux openSUSE Leap 42.1 Dovecot --version 2.2.18, Postfix Version: 2.11.6-3.1 Apache2 Version: 2.4.16-9.1 Connections 1. Evolution or Thunderbird to pop3 or imap reports: The reported error was "Could not connect to mail.privustech.com: Connection refused". Both connect successfully to googlemail.com with the same protocol: Port 993 SSL on a dedicated port I have also tried Port 143 STARTTLS after connecting without success 2. openssl s_client -connect mail.privustech.com:xxx a. xxx=25, 110, 143 all return error:140770FC b. xxx=993, 995 return socket: Connection refused connect:errno=111 3.telnet to a. smtp works. b. pop3 andy@tm2t:~> telnet 70.186.159.22 110 ... +OK POP3 2007e.104 server ready <48fa.572a0769(a)privustech.com> ... user andy -ERR Unknown AUTHORIZATION state command c. imap connects but does not allow login, and should not. http://marc.info/?l=imap&m=118775891829506&w=2 The most simple answer is "you cannot TELNET to a modern, correctly-configured, IMAP server and log in to it." andy@tm2t:~> telnet 70.186.159.22 143 ... * OK [...] privustech.com IMAP4rev1 2007e.404 at Wed, 4 May 2016 10:26:28 -0400 (EDT) ...

We have http and https to all vhost sites (privustech, mailprivustech, nptbeyond, gvhl, truthcourage, and their www. subsites). • Postfix reports no errors. We can log in on localhost, send a message to ourselves and see the message. • Dovecot: a. Logging is enabled in 10-logging.conf to /var/log/dovecot.conf but no logging has occurred there. b. doveconf -n throws no errors. Checks and tests completed 1. /etc/hosts is just fine. 2. Firewall is open for telnet, postfix, dovecot. 3. Added andy to dovecot, postfix groups, in addition to mail, reset password to ANDYbbs14@. 4. We tried enabling imaps, pop3s, but this command returns errors about these protocols being obsolete. https://tools.ietf.org/html/rfc2595 Use of these ports is discouraged in favor of the STARTTLS or STLS commands. 5. Reviewed doveconf -n: a. Note, there are no Dovecot users established other than user postfix group postfix service auth { unix_listener auth-userdb { group = postfix user = postfix } } i. postfix has its own set of users, including andy, which works just fine within postfix. We can send mail and read mail in the mailbox. b. Authentication is performed by PAM: passdb { driver = pam } i. Examined PAM: A. The files /etc/pam.d/xxx, where xxx = dovecot, pop, imap, are all the same lavarre:~ # cat /etc/pam.d/xxx #%PAM-1.0 auth include common-auth account include common-account password include common-password session include common-session B. They do not resemble at all the form presented in http://wiki2.dovecot.org/PasswordDatabase/PAM passdb { driver = pam args = %s } C. Add (B.) to see if that works: No change. Comment out the original (A.): No change. Restore it. c. SSL is required and apparently configured correctly (the less-than symbol '<'causes the succeeding file to be read into the variable): ssl = required ssl_cert = </etc/ssl/certs/dovecot.pem ssl_dh_parameters_length = 2048 ssl_key = </etc/ssl/private/dovecot.pem ssl_options = no_compression ssl_prefer_server_ciphers = yes userdb { driver = passwd } i. dovecot.pem, both cert and key, are installed in /etc/ssl as above and verified as a pair with openssl x509. And we point to them in /etc/dovecot/conf.d/10-ssl.conf as seen in the above. 6. Checked listening as it does not appear in doveconf -n: lavarre:~ # doveconf protocols listen protocols = imap pop3 lmtp listen = *, :: a. conf.d/10-master.conf ports for service xxx-login {inet_listener} are commented out. In fact, the entire file is commented out. Uncomment the listeners, restart. But no change. So undo.

It lately happens that I cannot open attachments in Thunderbird45.2.0. Only when I resend the email to myself I can open it. What could be done? Found out that with Outlook there is noproblem opening these attachments. Thanks, Jos -- AI is no match for natural ignorance

Managesieve problem
by Joseph Mays 22 Jul '16

22 Jul '16

Trying to get either avelsieve or server side filters to work with managesieve. Managesieve is running but whenever avelsieve or the server settings backend try to talk to it the same thing happens. So I guess it's really a problem with something about managesieve at this point. I hit the Message Filters option, it takes a long time for it to come back, though it finally just times out and does nothing, and immediately when I click on the Message Filters link the following two messages appear in /var/log/dovecot.... 2016-07-18 17:03:02 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=108(<getpwuid() error>) egid=65534(<getgrgid() error>) missing +x perm: /, dir owned by 0:111 mode=0750) 2016-07-18 17:03:02 managesieve-login: Error: auth: connect(login) in directory / failed: Permission denied (euid=108(<getpwuid() error>) egid=65534(<getgrgid() error>) missing +x perm: /, dir owned by 0:111 mode=0750) Seems to be straightforwardly a permissions error on a directory, but I don't believe it's really the / directory, so which directory is it? Any insights on where to look would be appreciated.

Disable auth_ssl_require_client_cert for SASL
by damir 22 Jul '16

22 Jul '16

Hello! Dovecot version - 2.2.6 Postfix version - 2.10.2 OS: Mageia Linux 4 x86_64 I have configured Dovecot imaps-server on 993 port to authenticate users via private certificates: auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = no Users' database is in OpenLDAP and in dovecot-ldap.conf.ext checking of users' passwords is disabled: pass_attrs = uid=%n, mail=%n@%d, =nopassword=1 It all works fine. I have configured Postfix submission-service on 587 port to connect users via StartTLS: submission inet n - y - - smtpd -o smtpd_tls_security_level=encrypt -o smtpd_enforce_tls=yes -o smtpd_tls_req_ccert=yes -o smtpd_tls_ask_ccert=yes -o smtpd_client_restrictions=permit_tls_all_clientcerts,reject -o smtpd_recipient_restrictions=permit_tls_all_clientcerts,reject -o smtpd_helo_restrictions=permit_tls_all_clientcerts,reject It works fine. And now I have a new task: I also need Postfix to authenticate OpenLDAP-users using SASL on smtps-port 465. I need it for using on mobile devices, which don't support StartTLS. So I have configured smtps in Postfix: smtps inet n - y - - smtpd -o smtpd_tls_wrappermode=yes -o smtpd_enforce_tls=yes -o smtpd_sasl_auth_enable=yes -o smtpd_sasl_type=dovecot -o smtpd_sasl_path=private/auth -o smtpd_client_restrictions=permit_sasl_authenticated,reject -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject_unauth_destination -o smtpd_helo_restrictions=permit_sasl_authenticated,reject While trying to connect to smtps, clients get an error: "Client didn't present valid SSL certificate", and this is clear. The question is: how to configure an additional auth-service in dovecot, which doesn't require private certificates and authenticates users using login/password?

Suggested improvement for antispam plugin documentation
by Ralph Seichter 21 Jul '16

21 Jul '16

Hello, I struggled a bit with getting the antispam plugin to work, because the plugin configuration in http://wiki2.dovecot.org/Plugins/Antispam is incomplete. After some twiddling, I ended up with this: # /etc/dovecot/conf.d/90-plugin.conf plugin { antispam_backend = mailtrain antispam_mail_spam = spam antispam_mail_notspam = ham antispam_mail_sendmail = /path/to/mailtrain/script antispam_spam = Junk;Spam antispam_trash = Deleted Messages;Trash } I know that the antispam plugin has not yet been officially released, but I think it might be worth updating the documentation anyway. Your thoughts? -Ralph

an e-mail client for dovecot ?
by Spyros Tsiolis 21 Jul '16

21 Jul '16

Hello all, For some years now, I've been using Thunderbird for dovecot. I am not very satisfied with t/b so I thought of using m/s outlook but then I thought that I want to distance my clients from office products. I have a newly created dovecot installation on a very small site. Three nodes, all x86 Windows 7 professional with an ubuntu v14.04 server (x86 again) running dovecot 1.2.17. The clients there use dovecot as an imap server, so they have a real-world e-mail account each and whatever they want to keep , they store by gradding-and-dropping to the imap (local / archive) account. Since I have quite some experiece with thunderbird, I know most of its shortcomings; So I thought if there's an alternative (better?) imap mail client for x86 windows 7 systems than t/b. Even better if there's an alternative client that is also supporeted under linux . Any ideas are welcome, TIA, s.t.

Absolute path in SUBSCRIPTIONS
by Miloslav Hůla 20 Jul '16

20 Jul '16

Hello, I'm using following two namespaces with Dovecot 2.2.13-12~deb8u1: namespace inbox { inbox = yes list = yes location = prefix = INBOX. # the previous Cyrus compatibility separator = . subscriptions = yes type = private ... } namespace { inbox = no list = children location = maildir:/vmail/user/%%n/Maildir:INDEXPVT=/vmail/user/%n/Maildir/Shared/%%n prefix = user.%%n. separator = . subscriptions = yes type = shared } For the shared namespace, the subscriptions are stored globally in '/vmail/user/%%n/Maildir/subscribtions' which is bad for me. I would like too keep subscriptions per user. I cannot set 'subscriptions = no' because I have no parent namespace. And when I set :SUBSCRIPTIONS=/vmail/user/%n/Maildir/subscriptions-shared it does not work (absolute path does not work) and it creates file in: /vmail/user/%%n/Maildir/vmail/user/%n/Maildir/subscriptions-shared instead of /vmail/user/%n/Maildir/subscriptions-shared I found, that relative path hack works: :SUBSCRIPTIONS=../../%n/Maildir/subscriptions-shared but I'm not sure it is the legitimate solution. Are there other options? Kind regards, Milo

Panic when runing "doveadm mailbox status ... vsize"
by Mark Costlow 19 Jul '16

19 Jul '16

I'm using dovecot 2.2.24 on FreeBSD 10.3. I'm working on converting users from maildir to mdbox, for the usual reasons. I have converted some test users and they generally work fine. But when I run "doveadm mailbox status" I get a Panic if I ask for the vsize field (or "all"), but other fields work fine. For example: # doveadm mailbox status -u bubbacheex3 "messages" INBOX INBOX messages=53 # doveadm mailbox status -u bubbacheex3 "guid" INBOX INBOX guid=bf976912f3748957761d0100f906a3d0 # doveadm mailbox status -u bubbacheex3 "unseen" INBOX INBOX unseen=52 # doveadm mailbox status -u bubbacheex3 "vsize" INBOX doveadm(bubbacheex3): Panic: file file-lock.c: line 269: unreached Abort trap I've only converted a few users, but they all exhibit this problem. I converted them with: dsync -u bubbacheex3 mirror maildir:/var/tmp/bubbacheex3 I have done a force-resync, which succeeds but doesn't change the behavior. I spent a little time trying to get gdb running but didn't get very far (couldn't seem to get it to find the source files once I got a few levels deep in the call stack). Before I beat my head on the gdb issue more, I thought I'd check here to see if anyone has any ideas. I didn't turn up anything in google or searching this list. Here's my "doveconf -n" output: ------------------------------------------------------ # 2.2.24 (a82c823): /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 10.3-RELEASE-p3 amd64 ufs auth_failure_delay = 1 secs auth_mechanisms = plain login auth_winbind_helper_path = /usr/local/bin/ntlm_auth auth_worker_max_count = 60 base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_gid = 100 first_valid_uid = 1000 listen = * login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_location = mdbox:/var/mail/%u:INDEX=/var/dovecot/%u mail_log_prefix = "%Us(%u): " mail_nfs_storage = yes mail_privileged_group = mail mdbox_rotate_interval = 1 days mdbox_rotate_size = 4 M mmap_disable = yes namespace { inbox = yes location = prefix = separator = . } passdb { args = session=yes dovecot driver = pam } protocols = imap pop3 service auth { unix_listener auth-client { mode = 0660 } unix_listener auth-master { mode = 0600 } user = root vsz_limit = 256 M } service imap-login { chroot = login process_limit = 128 process_min_avail = 10 service_count = 1 user = dovecot vsz_limit = 64 M } service imap { drop_priv_before_exec = no process_limit = 512 vsz_limit = 256 M } service pop3-login { chroot = login process_limit = 128 process_min_avail = 5 service_count = 1 user = dovecot vsz_limit = 64 M } service pop3 { drop_priv_before_exec = no process_limit = 512 vsz_limit = 256 M } ssl_cert = </etc/mail/certs/mail.swcp.com.pem ssl_cipher_list = ALL:!LOW:!SSLv2 ssl_key = </etc/mail/certs/mail.swcp.com.pem userdb { args = blocking=yes driver = passwd } verbose_proctitle = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep imap_logout_format = bytes=%i/%o imap_max_line_length = 64 k mail_max_userip_connections = 20 mail_plugin_dir = /usr/local/lib/dovecot/imap } protocol pop3 { mail_max_userip_connections = 10 mail_plugin_dir = /usr/local/lib/dovecot/pop3 pop3_client_workarounds = outlook-no-nuls oe-ns-eoh pop3_enable_last = no pop3_lock_session = no pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_no_flag_updates = no pop3_reuse_xuidl = yes pop3_uidl_format = %08Xu%08Xv } protocol lda { auth_socket_path = /var/run/dovecot/auth-master deliver_log_format = msgid=%m: %$ mail_plugin_dir = /usr/local/lib/dovecot/lda postmaster_address = postmaster(a)swcp.com quota_full_tempfail = yes rejection_reason = Your message to <%t> was automatically rejected:%n%r sendmail_path = /usr/sbin/sendmail } ------------------------------------------------------ Thanks, Mark -- Mark Costlow | Southwest Cyberport | Fax: +1-505-232-7975 cheeks(a)swcp.com | Web: www.swcp.com | Voice: +1-505-232-7992 Mail Minder - Intelligent Push Notifications for Email on the iPhone http://mailminderapp.com/download or in the App Store
