[Dovecot] listen directive changed?
by Nick Edwards 20 Apr '13

20 Apr '13

Timo, Is the global listen directive supposed to be a governing directive, like in apache? or is it there just in case you dont use it in protocols? I set a specific ipv6 address in global listen, but use [::] in proto Testing to a secondary IP, not in the global listen, it still connects, so can I ask has the original use of global listen been deprecated? ciao

[Dovecot] Moving mail servers, moving mailboxes
by Gregory Sloop 19 Apr '13

19 Apr '13

So, I've done some searching - but search terms are hard to come by, that work, for this query. In short, migrating a RHEL 5.9 server running the back-ported Dovecot 1.0.7 To: Ububtu 12.04 with 2.0.19, I believe. [I'm not against compiling a more recent version if there's some real advantage to doing so. But I'd certainly prefer to stay with the packaged version.] Most users are POP3, with some leaving messages on the server for a while. Other users are IMAP - whole mail repository on server. --- In an ideal world, I'd like to simply copy all the mailboxes/dirs from one server to the other. [Local/LAN file copies are possible] It would be great if the message ID's wouldn't change, so the read/unread/new etc status all all the messages wouldn't change between the two servers for POP/IMAP. --- So, does anyone have a reasonable walk-through for doing so? Is this a poor idea? Should I simply set myself on fire now and save everyone a lot of hassle? :) Would you suggest an alternative, and tell me if it might achieve the objectives above? I'm more than glad to take pointers to threads on this topic. I just haven't been able to dredge this up with my Google-foo. TIA -Greg

Sorry List, I am reposting with dovecot -n ------------------------------------------------------------------ Hi, all I've recently upgraded to 2.1.16 and found my self in deep .... There are 4 accounts in my setup that need to be accessed simultaneously by 5-6 PCs on a local lan.

To state this clearly, PC (A) thunderbird has an account SALES, Maildir etc PC (B) thunderbird also has the SALES account. Changes from PC (A) and vice-versa like marks,deletes, or moves mails around will randomly get propagated to PC (B) Sometimes they do sometimes they don't.

[Dovecot] Dovecot and port forwarding

Hello! I try to configure POP3s with Dovecot. My mail server is behind router and I forward 995 port from router to mail server. POP3s works ok when I log directly to 995 on server. Unfortunately, it shows nothing when I log from outside. It happens also when the firewall is off. All I can see in log is this: Apr 19 13:39:43 hostname dovecot: pop3-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [123.123.123.123] Apr 19 13:39:43 hostname dovecot: pop3-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [123.123.123.123] Apr 19 13:39:43 hostname dovecot: pop3-login: Warning: SSL: where=0x2002, ret=-1: unknown state [123.123.123.123] Apr 19 13:39:43 hostname dovecot: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Apr 19 13:39:43 hostname dovecot: auth: Debug: auth client connected (pid=17056) Apr 19 13:39:47 hostname dovecot: pop3-login: Disconnected (no auth attempts): rip=123.123.123.123, lip=10.0.0.2, TLS handshaking: Disconnected (hostname and IPs changed) My config: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-40-generic-pae i686 Ubuntu 12.04.2 LTS auth_debug = yes mail_location = mbox:~/mail:INBOX=/var/mail/%u mail_privileged_group = mail passdb { driver = pam } protocols = pop3 service pop3-login { inet_listener pop3s { address = * } } ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { driver = passwd } verbose_ssl = yes I think it might be something related to SSL, but what?

Hello Many users here use the "copy to Sent folder" using the IMAP protocol with Dovecot 2.1.15 on a FresBSD 9 server. Since few days this operation ( copy to sent folder ) became longer than before , it could takes several seconds to complete even the message is very short. Is there a parameter I could tweak to boost this a bit ? may users complain with reason thank you

[Dovecot] Problem with "convert" Plugin
by Andreas Schnederle-Wagner - Futureweb.at 18 Apr '13

18 Apr '13

Hello, I got a Problem with the "convert" Plugin. Trying to convert from mbox to maildir Format. OS: CentOS release 5.8 (Final) dovecot -version: 1.0.7 (Centos RPM) convert Plugin call: convert_mail = mbox:/opt/pop3/%u:INBOX=/var/spool/mail/%u When converting to maildir - POP3 works fine (except the lost UIDL - so every server-saved message is double downloaded - but did not find any fix for this problem with convert plugin) But the IMAP In-Boxes give me some headache . All Folders are converted correct - and displayed in Mail Client. But all Mails in the IMAP INBOX are "lost" (at least Mail Client won't show them anymore) Newly delivered Mails to the Inbox work - but all older ones are missing. When looking into this Folder: /var/maildata/USER/Maildir/cur/ I can see that newly delivered mails look like this: 1366122898.14776_0.SERVERNAME:2, And the old - converted ones like this: 1366119758.P14442Q12M682874.SERVERNAME:2, Can someone point me in the right direction why the converted Mails are missing? (It worked on other Servers - about 1 year ago - without any problem?!)

[Dovecot] qmail-ldap LDA Delivery and sieve
by Ruda Porto Filgueiras 18 Apr '13

18 Apr '13

Hi, I'm using dovecot 2.1.7 on debian Squeeze with ldap integration. Almost everything is working fine and I would link to thank all developers for this amazing piece of software. But after changing my qmail-ldap to do LDA integration get all the benefits from LDA and sieve, some emails return with failure like this: <sar(a)mondialline.com.br>: lda(sar): Fatal: Unknown argument: sar Usage: dovecot-lda [-c <config file>] [-a <address>] [-d <username>] [-p <path>] [-f <envelope sender>] [-m <mailbox>] [-e] [-k] It happens on messanges that could not be delivered and need to be returned to the sender. I'm using the configuration described on wiki to do qmail-ldap integration: http://wiki.dovecot.org/HowTo/qmailldap The relevant delivery command is: | /usr/lib/dovecot/dovecot-lda -a $RECIPIENT -f $SENDER -d $USER I also tried to use this way, as documented here: http://wiki2.dovecot.org/LDA/Qmail | /var/qmail/bin/preline -f /usr/lib/dovecot/dovecot-lda But in that case, some sieve plugins can't detect the mail recipient, like vacation plugin. Finally, the vacation plugin also is not doing email forwarding when I use the first delivery option above.

[Dovecot] Pros and cons of having folders under INBOX vs. not
by Rich Wales 18 Apr '13

18 Apr '13

I have some questions about whether I should set up folders under INBOX vs. having them outside the INBOX namespace. I'm setting up a new Dovecot 2.2.0 on an Ubuntu 12.04.2 server. My plan is to move my users (family members) to this new server from an old Cyrus server. Everybody is currently using (and will continue to use) IMAP, and either Thunderbird or SquirrelMail as their e-mail client. I'm using the maildir mailbox format on this new Dovecot server. No one is using the new Dovecot server yet, so I'm still free to do additional tweaking of the server configuration. When I used imapsync to copy everyone's mail to the new server, I found that all the folders (other than INBOX) were renamed. On the old Cyrus server, all the folders are subfolders of INBOX, but the folders on the new Dovecot server are not. (For example, a folder named "INBOX.Dovecot" on the old server was renamed to "Dovecot" on the new server by the imapsync utility.) Can I just keep things this way on the new server? Or are my users going to run into problems if folders are not all under INBOX? I do realize that IMAP servers can be set up either to put everything under INBOX, or not, but I'm not familiar with all the pros/cons. And if I do need (or want) to put all the folders under INBOX, can I simply rename the existing folders in each user's Maildir (and also edit folder names accordingly in everyone's "subscriptions" file)? Or will Dovecot be broken unless I recopy everything from scratch (with a command-line option to imapsync to put everything in the INBOX destination namespace)? Rich Wales richw(a)richw.org

[Dovecot] Dovecot 2.2 & LEMONADE extensions
by Jan Phillip Greimann 18 Apr '13

18 Apr '13

Hi there, I read an article about dovecot 2.2, which includes the LEMONADE extensions, and was fascinated about the feature "Forward without download". We have a small internet-uplink in our office and our CEO loves to receive mails with large attachments, he also reply/forward it, so every time the full attachments get downloaded and uploaded again. Now the question is: Is LEMONADE supported by desktop-mailclients like thunderbird or just mobile Clients? (Google said nothing to this, maybe searched the wrong words) I hope someone can help me with this. Greetings, Jan

[Dovecot] Maildirs location migration
by Thomas Hummel 17 Apr '13

17 Apr '13

Hello Timo, I'm using dovecot-2.1.15 with Maildir mailboxes located on an NFS filer. Postfix is used to deliver mail through procmail ("mailbox_command) as LDA. Our team has bought another filer and everything is meant to go on it, so we're planning to migrate those mailboxes to the new filer. To test it only on a subset of users, I ended up to the following solution : 1. keep new messages in postfix mailqueue for those users (via a service and a transport) 2. prevent new dovecot authentication for those users (via the "auth-deny" passwd-file type passdb) 3. doveadm kick those users 4. copy or rsync the mailboxes 5. symlink maildir, control and indexes directories to the new filer (nfs mounted on the mail server) 6. re-enable mail delivery and imap authentication I was wondering if such a migration could be done differently in order to be seamless to the user : - for the postfix part, it would be easy, I guess, to create a new service (and a new transport map using this service) to deliver to the new location - but for the imap part, I'm not sure if it can be done. My guess is that, if feasible, it would involve some namespace settings and a dsync copy but I cannot figure out how exactly. What do you think ?

by FABIO FERRARI 17 Apr '13

17 Apr '13

Hello, recently I have migrated a dovecot configuration from a Red Hat 5 to a CentOS 6. Since the versions of dovecot are quite the same (dovecot-2.0.1-1_118.el5 vs dovecot-2.0.9-5.el6.x86_64), I was thinking that copying the configurations file from one server to the other was a good thing, but instead, when I try to start the service, I have this bad error: Avvio di Dovecot Imap: doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: service(anvil): process_limit must be 1 Does anyone know why I am getting this? Is there a change in configurations between the 2 versions, is it a known issue or I have to check something else? thanks in advance Fabio Ferrari

[Dovecot] %{session} does not work with deliver_log_format
by Daniel Parthey 17 Apr '13

17 Apr '13

Hi, # 2.1.10: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-45-server x86_64 Ubuntu 10.04.4 LTS deliver_log_format = mailbox: deliver: session=<%{session}> msgid=%m from=%f: %$ produces log messages always containing "session=<session}>", like this one: Feb 24 09:22:09 10.129.3.233 dovecot: lmtp(3484, user(a)example.org) mbnWK6/NKVGcDQAAiWCYmA: sieve: mailbox: deliver: session=<session}> msgid=<20130224082208.8A807C0CF(a)mx01.example.org> from=postmaster(a)example.org: stored mail into mailbox 'INBOX/postmaster' http://wiki2.dovecot.org/Variables leads me to the assumption that %{session} works "everywhere" and for deliver_log_format too. Is deliver_log_format variable expansion handled differently from login_log_format_elements and mail_log_prefix? Regards Daniel -- https://plus.google.com/103021802792276734820

The best way to figure out why it works and v2.2 doesn't would be to find the specific commit from v2.2 that broke it. http://mercurial.selenic.com/wiki/BisectExtension could make finding that easier.

[Dovecot] Delete_to_Trash plugin and quota problem
by BINOTTO Luis SIDOR 16 Apr '13

16 Apr '13

Hello list... I am new at dovecot and I have a problem with it; any help will be very grateful We have a exchange server with outlook at the client side, and we are migrating the exchange server to postfix/dovecot(1.2.15) solution. I enabled the "deleted-to-trash" plugin (v0.3) to move the messages to the Trash folder automatically when it is deleted. Also, I am using quota and quota_imap plugins to maintain the quota for users. The quota rule for Trash folder is unlimit. The problem is, when the client reach their maximum quota and try to delete a mail in the inbox to release space. The delete to trash plugin effectively copy it to the Trash folder, but the original mail still remain (marked for delete) at the inbox folder and the quota does not released.

[Dovecot] [PATCH] mailbox_get_metadata() for mailboxes with open transactions.
by Dafan Zhai 16 Apr '13

16 Apr '13

Hi everyone, I am writing a dovecot statistic plugin, which calls mailbox_get_metadata() to get the virtual size of the mailbox, if a mail is copied. I have noticed that mailbox_get_metadata() calls mailbox_sync(), and mailbox_sync() will fail for the mailboxes with open transactions. But if a mail is copied, there must be at least one transaction opened for the mailbox. So I can not get the virtual size. Commit [1] has fixed the same problem in mailbox_get_status(). I think the same should also be done in mailbox_get_metadata(). See the patch below. Dovecot version: 2.2.0 OS: OS: Linux 3.4.39-dist i686 maildir:~/Maildir:LAYOUT=fs:INBOX=~/Maildir/INBOX Dafan [1] http://hg.dovecot.org/dovecot-2.2/rev/12136db6e31f # HG changeset patch # User Dafan Zhai <dafan.zhai(a)securepoint.de> # Date 1366118323 -7200 # Node ID 7f0c5122d863d303ef5e74bbf650c2bac89ac564 # Parent f33bacb03cc22e02ca2d11d527d8dc0d99214486 lib-storage: mailbox_get_metadata() no longer forces mailbox to be synced.

[Dovecot] Dovecot 2.2 multiple master user passdb's not working anymore
by Christian Wiese 16 Apr '13

16 Apr '13

Hi, after an update from dovecot 2.1.16 to 2.2.0 I encountered a problem when using multiple master user passdb's like the following: ----%<--------------------------------------------------------- passdb { args = /etc/dovecot/passwd.foo-master driver = passwd-file master = yes } passdb { args = /etc/dovecot/passwd.bar-master driver = passwd-file master = yes } ----%<--------------------------------------------------------- The former behavior that the passdb's are searched sequentially to find the given master user doesn't seem to work anymore. Only the first passdb is searched, and thus authentication will fail for all master users which are not defined in the first passdb. Because I cannot find any hint that the master user handling has changed fundamentally it looks like a bug, but maybe I missed configuration related changes from 2.1 to 2.2 that is causing this new behavior. Cheers, Chris

[Dovecot] Probs authenticating to Dovecot
by Kris Magnusson 16 Apr '13

16 Apr '13

Hi folks. I have set up a Ubuntu 12.04 VM with Dovecot, Postfix, MySQL, amavisd, and ISPConfig 3. The VM has tons of RAM and disk and processor and is permanently connected to the Internet with a static IP. I followed the instructions at howtoforge.com to set up and configure this VM and am using ISPConfig to set up a mail hub for multiple domains. I have the DNS for my other domains' MX records pointing at this host—we'll call it "mail." Here's the version of Dovecot I'm using: root@mail:# dovecot --version 2.1.7 Anyway, when I try to connect to my VM and Dovecot using Mail.app on Mountain Lion, I get the following messages in mail.log: Apr 15 01:18:40 mail postfix/smtpd[4284]: connect from 50-196-170-xxx-static.hfc.comcastbusiness.net[50.196.170.xxx] Apr 15 01:18:40 mail dovecot: auth-worker(4331): mysql(localhost): Connected to database dbispconfig Apr 15 01:18:42 mail postfix/smtpd[4284]: warning: 50-196-170-xxx-static.hfc.comcastbusiness.net[50.196.170.xxx]: SASL PLAIN authentication failed: Apr 15 01:18:42 mail postfix/smtpd[4284]: disconnect from 50-196-170-xxx-static.hfc.comcastbusiness.net[50.196.170.xxx] Apr 15 01:18:54 mail dovecot: imap-login: Disconnected (auth failed, 1 attempts in 6 secs): user=<kris>, method=PLAIN, rip=50.196.170.xxx, lip=50.196.170.yyy, TLS, session=<wwn85mHa8AAyxKq9> Apr 15 01:19:04 mail dovecot: imap-login: Disconnected (auth failed, 1 attempts in 10 secs): user=<kris>, method=PLAIN, rip=50.196.170.xxx, lip=50.196.170.yyy, TLS, session=<XGdT52Ha8QAyxKq9> But if I run alpine on mail, I can send and receive mail all day long.

The mailbox is created, it works on the host, so why wouldn't it work over the network? I've tried frobbing settings in Mail.app, as it does have some wonkiness to it, but no dice. The password is fine, everything is in place, it just doesn't work. Any thoughts or recommendations? Thanks, Kris

[Dovecot] [OT] xi.rename-it.nl dovecot-2.2 stable-auto
by Jan Phillip Greimann 16 Apr '13

16 Apr '13

Hi there, I check my mail-server for debian package-upgrades with Nagios, so everyday I got a mail for 8 "new" dovecot-packages on this server. I think that wasn't so in 2.1 stable-auto, but I'm not sure about that. Maybe someone who uses the 2.1 stable-auto repo could response to this? But 2.2 released only few days ago, maybe the repo-admin hadn't time to change this, or my memory about this is wrong. best regards, Jan

[Dovecot] Dovecot IMAPS and slow reconnections
by Jarrad 16 Apr '13

16 Apr '13

Hi List, I've recently moved from postfix + courier-imap to a new server with postfix + dovecot with a mysql user management. I have it up and running and receiving mail ok but I'm having problems with IMAP connections being slow. I have an iphone with multiple imap accounts set up on it (4 I think) and when I open the mail app it connects to first account quickly. Then if I navigate to another account it takes about 1 minute to connect (sits there with the 'connecting....' status) Looking at the logs it shows the connection come through at the same time the iphone actually connects so it's as if something is timing out before it actually connects. My setup is an Amazon EC2 micro instance running debian wheezy. There is about 5 domains being hosted with approximately 4-5 accounts for each so it's not a heavy load by any means. I've tried bumping up the max connections, service_count and minimum processes but nothing seems to help. Any advice is much appreciated. My config is as per below: # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.0 ext4 auth_debug = yes auth_verbose = yes disable_plaintext_auth = no mail_location = maildir:/var/vmail/%d/%n/Maildir 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 = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocols = " imap pop3" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-master { group = vmail mode = 0600 user = vmail } } service imap-login { process_min_avail = 5 service_count = 10 } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.key userdb { args = uid=5000 gid=5000 home=/var/vmail/%d/%n/Maildir allow_all_users=yes driver = static } verbose_ssl = yes protocol lda { auth_socket_path = /var/run/dovecot/auth-master log_path = mail_plugins = postmaster_address = <removed for spam reasons> } protocol imap { mail_max_userip_connections = 100 }

[Dovecot] SSHA512 auth not working
by Marcin Czupryniak 16 Apr '13

16 Apr '13

I'm trying to configure SSHA512 passwords and when testing discovered that they were not working as expected. At first i was using Centos 6.4 which doesn't have the glibc CRYPT newest functions ($6$salt$pass) so had to rollback to the Dovecot format ({SSHA512.HEX}saltedpassword+salt ) but I'm unable to let dovecot authenticate properly. Some logs and details: Apr 16 02:55:37 auth: Debug: client in: AUTH 1 PLAIN service=imap lip=xxx rip=xxx lport=143 rport=58171 resp=AGRpbm9AYWJjLml0AGRpbm8= Apr 16 02:55:37 auth: Debug: sql(dino(a)abc.it,xxxx): query: SELECT '{SSHA512.HEX}' || password as password FROM mailboxes WHERE fullusername='dino(a)abc.it' Apr 16 02:55:37 auth: Info: sql(dino(a)abc.it,xxxx): Password mismatch (given password: dino) Apr 16 02:55:37 auth: Error: md5_verify(dino(a)abc.it): Not a valid MD5-CRYPT or PLAIN-MD5 password Apr 16 02:55:37 auth: Warning: Invalid OTP data in passdb Apr 16 02:55:37 auth: Warning: Invalid OTP data in passdb Apr 16 02:55:37 auth: Debug: sql(dino(a)abc.it,xxxx): SSHA512.HEX(dino) != 'd449914d83c85a786bcde7114b3dfdb24a651c27956388ac641d46eaf40c86e7c95ce2534348730475c8893eab314af189b3a46bf6d76b82cfba119e920813a531e985acd35c47ca8d3cafe50b595b66' Apr 16 02:55:39 auth: Debug: client out: FAIL 1 user=dino(a)abc.it Full password as taken from database: {SSHA512.HEX}d449914d83c85a786bcde7114b3dfdb24a651c27956388ac641d46eaf40c86e7c95ce2534348730475c8893eab314af189b3a46bf6d76b82cfba119e920813a531e985acd35c47ca8d3cafe50b595b66 The first 128 chars are the salted password, remaining 32 the salt (hex uuid representation) I've checked twice that the generated passwords are correct, in fact if you salt the password (dino) you get the exact 128chars as in the stored password but dovecot compares the full password with the salt (160 chars), is this correct? Any ideas?

[Dovecot] rsync migration issue
by Luigi Rosa 16 Apr '13

16 Apr '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am trying to migrate a mail server from an old VM to a new one. I have maildir and virtual users, the files and dirs of the file system are owned by a single user. I exported the old (now in production) /var/spool/mail with (ro,no_root_squash) parameters I mounted the NFS on the new server with -o nolock This is not the first time I use this method and it always worked.

[Dovecot] Delete_to_Trash plugin problem
by BINOTTO Luis SIDOR 15 Apr '13

15 Apr '13

Hello list... I am new at dovecot and I have a problem with it; any help will be very grateful We have a exchange server with outlook at the client side, and we are migrating the exchange server to postfix/dovecot(1.2.15) solution. I enabled the "deleted-to-trash" plugin (v0.3) to move the messages to the Trash folder automatically when it is deleted. Also, I am using quota and quota_imap plugins to maintain the quota for users. The quota rule for Trash folder is unlimit. The problem is, when the client reach their maximum quota and try to delete a mail in the inbox to release space. The delete to trash plugin effectively copy it to the Trash folder, but the original mail still remain (marked for delete) at the inbox folder and the quota does not released. Am I doing something wrong? Thanking you in anticipation.... Luis Binotto. " Notificacion Automatica: Este mensaje y cualquier archivo que se adjunte contiene informacion privilegiada y confidencial.

[Dovecot] Dict quota question
by Antoine Nguyen 15 Apr '13

15 Apr '13

Hi all, I'm using Dovecot 2.1.16 and I'd like to know if the following configuration is supported: * An SQL dictionary quota * A static userdb to get uid/gid/home information * An SQL userdb to get per-user quota limit Currenlty, current quota usage are properly stored into the database but per-user limits are not found. If I replace the SQL dictionary by the maildir backend (my previous config.), it works as expected. Do you have any idea? Thanks in advance, Antoine Nguyen http://modoboa.org/

[Dovecot] lazy_expunge plugin with virtual mailboxes
by Gilles Chauvin 15 Apr '13

15 Apr '13

Hi, When using both lazy_expunge and virtual mailboxes (with, for instance, a "All Messages" virtual mailbox) as soon as a user deletes/expunges a mail in one of its mailbox, Dovecot is saving two mails to the lazy_expunge namespace (the one in the user mailbox and the one in the virtual mailbox). Is there some kind of trick to make Dovecot ignore any mail deleted from a virtual mailbox namespace ? Thanks, Gilles.

But the length of the hash is consant + encoded(salt) + encoded (hash(password)), all of which ought to be fixed lengths. Joseph Tam <jtam.home(a)gmail.com>

[Dovecot] How to manually generate a password hash
by David Murphy 14 Apr '13

14 Apr '13

Hi folks. I've recently set up a Postfix 2.9.6/Dovecot 2.0.19 IMAPS/SMTPS setup on Ubuntu 12.04.2 (Mysql backend). I'm new to all this, so I apologize if this is fairly basic. I've attempted to the best of my ability to search for an answer, but no luck so far. What I'm trying to do is generate a password hash that I can inject directly into my Mysql database (disaster recovery sort of situation). Towards that goal, I'm trying to use 'doveadm pw' to generate a hash that matches a known password in my database. Unfortunately, I'm coming up empty. My default_pass_scheme in dovecot-sql.conf is set to MD5-CRYPT, and the passwords in the database have no scheme prefixes. I'm attempting to generate a hash with: sudo doveadm pw -s 'MD5-CRYPT' but the hash generated does not match the user's password hash in the database, which is known to be a good password. I'm able to log into this account successfully in both Roundcube and a remote IMAP client. I've also tried using the -p flag and including the password in the command, and that doesn't do it either, though it oddly gives a different response than using the prompt. (What causes this? Newlines?) So... what am I missing? If the hash was salted, it would seem the hashes in the database would be longer than the ones generated at the command line, but that isn't the case. I'm out of ideas. Any guidance appreciated. -Dave

[Dovecot] LMTP Setup/Design Help Request

Hi again, Thank you for your first hints. I have now set up a dedicated test instance of postfix and dovecot to be able to recreate the problems in detail. Even after using your inputs, they do not seem to work with my setup I already mentioned above. I get errors like postfix/lmtp[10994]: C2DF4C000DF: to=<user1(a)mydomain.org>, relay=mail.mydomain.org[private/dovecot-lmtp], delay=0.1, delays=0.05/0/0/0.04, dsn=5.1.1, status=bounced (host mail.mydomain.org[private/dovecot-lmtp] said: 550 5.1.1 <user1(a)mydomain.org> User doesn't exist: user1(a)mydomain.org (in reply to RCPT TO command)) As stated before, my setup is as follows: > I only have virtual users and have set > > mail_uid = dovemail > mail_gid = dovemail > > For authentication, I simply use (for now) a flat file: > > passdb { > driver = passwd-file > args = scheme=PLAIN username_format=%u /etc/dovecot/mypasswd.file > } > > # cat /etc/dovecot/mypasswd.file > user1:{PLAIN}userpw1 > user2:{PLAIN}userpw2 > user3:{PLAIN}userpw3 > > And everything works fine with IMAP. I am completely domain-agnostic > here. I do not know how to strip the domain when the username is handed over from postfix to dovecot, and what would be the sane solution. I hope, you can give me a hint to that. Thank you, again, and greetings, Matthias Hofer
