[Dovecot] Dovecot 2.0.5 crash when It cannot remove maildir
by Len7hir 02 Nov '10

02 Nov '10

This is scenario that cause segmentation fault in my Dovecot. Maybe I do something wrong, but I don't know what... We run: mailbox_delete mailbox_delete do: mailbox_open(box) < 0 and after we have: box->v.delete(box) which run index_storage_mailbox_delete index_storage_mailbox_delete do: mailbox_close(box); and now mailbox is closed (this close box->view and mailbox open) Try to delete folder, but can't do this... example becaus it is system folder, or NFS failure... set error message and return -1. Now we are returning to mailbox_delete. And we have: if (ret < 0 && box->marked_deleted) and this is true mailbox_mark_index_deleted(box, FALSE) if (box->marked_deleted && del) this is false mail_index_transaction_begin(box->view, trans_flags); mail_index_view_ref(view) and segmentation fault, because view is 0x0 #0 mail_index_view_transaction_ref (view=0x0) at mail-index-view.c:81 #1 0xb7ef3214 in mail_index_transaction_begin (view=0x0, flags=MAIL_INDEX_TRANSACTION_FLAG_EXTERNAL) at mail-index-transaction.c:268 #2 0xb7eb7a73 in mailbox_mark_index_deleted (box=0x80c8268, del=false) at mail-storage.c:682 #3 0xb7eb80a9 in mailbox_delete (box=0x80c8268) at mail-storage.c:757 #4 0x0805001f in cmd_delete (cmd=0x8095978) at cmd-delete.c:46 #5 0x0805625c in client_command_input (cmd=0x8095978) at imap-client.c:741 #6 0x0805630b in client_command_input (cmd=0x8095978) at imap-client.c:791 #7 0x0805646d in client_handle_input (client=0x8095390) at imap-client.c:857 #8 0x08056f1f in client_input (client=0x8095390) at imap-client.c:908 #9 0xb7e6f110 in io_loop_handler_run (ioloop=0x806c370) at ioloop-epoll.c:212 #10 0xb7e6da98 in io_loop_run (ioloop=0x806c370) at ioloop.c:350 #11 0xb7e5b26a in master_service_run (service=0x806c2c0, callback=0x805f800 <client_connected>) at master-service.c:496 #12 0x0805f6da in main (argc=1752462689, argv=0x73616d2d) at main.c:358 This is Dovecot error or I do something wrong? -- Len7hir

[Dovecot] Problem with namespace (maybe bug?)

Hi! Could you tell me what is wrong with an "existence" of mailbox? Please see the two examples: . list "" "*" * LIST (\HasNoChildren) "/" "Trash" * LIST (\HasNoChildren) "/" "Junk" * LIST (\HasNoChildren) "/" "Sent" * LIST (\HasNoChildren) "/" "Drafts" * LIST (\HasNoChildren) "/" "Archives" * LIST (\HasNoChildren) "/" "INBOX" * LIST (\HasNoChildren) "/" "Public/AddressBook" * LIST (\HasNoChildren) "/" "Public/PublicMails" * LIST (\Noselect \HasChildren) "/" "Shared/dziobak" * LIST (\Noselect \HasChildren) "/" "Shared/tester2" * LIST (\HasNoChildren) "/" "Shared/dziobak/root" * LIST (\HasChildren) "/" "Shared/tester2/sdfgsg" * LIST (\HasChildren) "/" "Shared/tester2/sdfgsg/gsdfgf" * LIST (\HasChildren) "/" "Shared/tester2/sdfgsg/gsdfgf/vtyjyfgj" * LIST (\HasChildren) "/" "Shared/tester2/sdfgsg/gsdfgf/vtyjyfgj/rtdhrthxs" * LIST (\HasNoChildren) "/" "Shared/tester2/sdfgsg/gsdfgf/vtyjyfgj/rtdhrthxs/zhfhg" .

[Dovecot] Help with implementing quota warning
by Joy 02 Nov '10

02 Nov '10

Dear All, I am using the latest version of doveot-2.0.6 and using dovecot-lda to deliver mail in to Maildir. I have successfully implemented the global quota as well as per user quota using ldap for storing per user quota. Now i am trying to send warning message when user exceed quota limit of 80% and 95% but unable to implement the same.

[Dovecot] Dovecot 2.0.5 - multiple auth processes.
by Marek Miska 02 Nov '10

Hi. On Dovecot 1.2.x it is possible to run multiple auth daemons. Is it possible on dovecot 2.0.x ? (Setting "process_min_avail" for auth service gives this error message: "doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: service(auth): process_min_avail is higher than process_limit") Sample configuration for dovecot 1.2.8: auth default { count = 10 mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root } auth lda { mechanisms = plain passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } user = root socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 } } }

[Dovecot] Help Dovecot / vpopmail auth process...
by postmaster＠cyborspace.com 02 Nov '10

Please forgive my previous posts, sending mail manually since i cant get the auth to work. Thought i had the body cut and pasted correctly. I am pulling my hair out, i think I know what is wrong - i just cant find out how to fix it. Using Debian - lenny it appears that the auth process - is not looking for / seeing the proper file or database for the lookup. i would like it to point to the cdb file stored ~/domains/%d/ <---- assuming the %d = domains - and the file would then be vpasswd.cdb......

[Dovecot] Namespace subscription issue
by Brad Davidson 02 Nov '10

02 Nov '10

I'm a little confused about how public namespaces work with subscriptions. If I set subscriptions=no and subscribe to the folders, the subscription entries go into the user's private subscription file and that's fine. However, I am unable to pull their status with the LIST-EXTENDED extension. Normal listing works OK: A0004 LIST "" "*" RETURN (STATUS (MESSAGES UNSEEN)) * LIST (\NonExistent) "/" "Public" * LIST () "/" "Public/Public One" * STATUS "Public/Public One" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public One/Sub 1" * STATUS "Public/Public One/Sub 1" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public One/Sub 2" * STATUS "Public/Public One/Sub 2" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Public Two" * STATUS "Public/Public Two" (MESSAGES 0 UNSEEN 0) * LIST () "/" "Public/Read-only" * STATUS "Public/Read-only" (MESSAGES 1 UNSEEN 0) A0004 OK List completed. Listing SUBSCRIBED (or LSUB) fails: A0003 LIST (SUBSCRIBED) "" "*" RETURN (STATUS (MESSAGES UNSEEN)) * LIST (\Subscribed) "/" "Public/Public One" * NO Mailbox doesn't exist: Public.Public One * LIST (\Subscribed) "/" "Public/Public One/Sub 1" * NO Mailbox doesn't exist: Public.Public One.Sub 1 * LIST (\Subscribed) "/" "Public/Public One/Sub 2" * NO Mailbox doesn't exist: Public.Public One.Sub 2 * LIST (\Subscribed) "/" "Public/Public Two" * NO Mailbox doesn't exist: Public.Public Two * LIST (\Subscribed) "/" "Public/Read-only" * NO Mailbox doesn't exist: Public.Read-only A0003 OK List completed. If I set subscriptions=yes it works OK, but then the subscriptions are shared unless I override SUBSCRIPTIONS in the mail location. Is this working as designed? Here's what I ended up doing - is there a better way? namespace { inbox = yes location = prefix = separator = / type = private } namespace { hidden = yes list = no location = maildir:%h/Maildir prefix = ~/mail/ separator = / type = private } namespace { type = public separator = / prefix = Public/ location = maildir:/var/mail/public:INDEX=~/Maildir/public:SUBSCRIPTIONS=~/Maildir/ public/subscriptions subscriptions = yes } --- Brandon 'Brad' Davidson Virtualization Systems Administrator University of Oregon Information Services (541) 346-8098 brandond(a)uoregon.edu

[Dovecot] What causes the quota information to get updated?
by Patrick Westenberg 02 Nov '10

02 Nov '10

Hello, if new mails arrive, the quota information is updated and reported via imap immediately. However, after deleting a message, nothing happens. Even if I delete all messages and the mailbox e.g. was over quota, new mails won´t be accepted because the mailbox is over quota. Is this the way it should be or a misconfiguration? # 2.0.4: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.26-2-amd64 x86_64 Debian 5.0.5 auth_mechanisms = plain login log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_gid = vmail mail_location = mdbox:~/mdbox mail_plugins = quota mail_uid = vmail managesieve_notify_capability = mailto managesieve_sieve_capability = comparator-i;octet comparator-i;ascii-casemap fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } plugin { quota = dict:User quota::file:%h/mdbox/dovecot-quota quota_rule2 = INBOX.Trash:storage=+50M quota_warning = storage=95%% quota-warning 95 %u quota_warning2 = storage=5%% quota-warning 5 %u sieve = ~/.dovecot.sieve sieve_global_path = /usr/local/etc/dovecot/sieve/default.sieve } protocols = imap sieve service imap-login { service_count = 1 } service managesieve-login { inet_listener sieve { port = 4190 } inet_listener sieve_deprecated { port = 2000 } service_count = 1 } ssl = required ssl_cert = </etc/ssl/certs/imap_wk-serv_net.crt ssl_key = </etc/ssl/certs/imap_wk-serv_net.key userdb { args = /usr/local/etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol imap { mail_plugins = $mail_plugins imap_quota }

[Dovecot] LDAP acl_groups - can multivalue LDAP be used
by ian+dovecot＠comtek.co.uk 02 Nov '10

02 Nov '10

Hi, Is there some kind of way to get acl_groups out of LDAP without having to maintain an entry with a list of groups 'a,b,c' and so on? Our groups have a list of 'member' attributes with CNs pointing at users. Ideally there would be a way to look this up directly. Alternately I could perhaps use an OpenLDAP overlay to show 'group' attributes for each user's ldap entry. I would then like to be able to tell it to get all 'group' attributes and comma-separate them. The best option I've seen so far is something like http://www.dovecot.org/list/dovecot/2010-March/047731.html which seems to involve a completely separate LDAP session from a login script. Thanks in advance for any help, Ian

[Dovecot] problem with folder creation
by John Watson 02 Nov '10

02 Nov '10

I am running dovecot 1.2.12 on Free BSD 8.1. We also have postfix and a version of squirrelmail for the UI. We are using MySql database to store the email account info. I wrote a script to insert about 100K users into mysql. Those accounts seem to work well and I'm able to see things like 'Drafts', 'Trash' and 'Sent'. Now I am working on code to create new accounts - one at a time. The accounts get created and I can send and receive email from them but when I go go Drafts, Sent or Trash I get an error that says: ERROR: Could not complete request. Query: SELECT "INBOX.Drafts" Reason Given: Mailbox doesn't exist: INBOX.Drafts When I go out and look at the mailbox folders for these users I only see "cur", "new", and "tmp" whereas on other accounts that work well I also see things like INBOX.Drafts etc. I have examined the sql that is inserting the accounts in bulk versus the one by one case and can not see any differences (other than a new mailbox name/password etc). Everything that I'm reading online indicates that Dovecot should just create these extra folders on the server and there is really nothing for either an admin or a user to do. Does anyone have any more information on this? Thanks in Advance John Watson

[Dovecot] Doveadm-Expunge v2.0.5
by Kui Zhang 02 Nov '10

02 Nov '10

Hello Few questions regarding Doveadm-Expunge. 1. I have lazy expunge configure with this name space: .EXPUNGED Storage type: mdbox doveadm -Dv expunge -u user@domain mailbox ".EXPUNGED/*" savedbefore 7d I get some interesting outputs. doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=791 doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=792 doveadm(user@domain): Debug: expunge: box=.EXPUNGED/INBOX/mon uid=793 .... doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=196, msgid=<E1OwJm4-0000j4-1l@domain>, size=1856 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=197, msgid=<E1OwJmP-0000pr-4M@domain>, size=1756 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=198, msgid=<E1OwJpP-0002Hp-Pu@domain>, size=1810 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=199, msgid=<E1OwJqw-0002y7-AF@domain>, size=1766 doveadm(user@domain): Info: expunge: box=INBOX/mon, uid=200, msgid=<E1OwJud-0004ba-Fe@domain>, size=1890 ... So what is the diff between "Debug: expunge" and "Info: expunge". Anything done to "Info: expunge"? I am assuming the "debug: expunge" are the only entries with actions. And "Info: expunge" is not doing anything. I ran doveadm purge -u user@domain after. I did not notice any missing emails. Sorry for the trivial question, I just want to make sure not mail would disappear, all of sudden. 1.A. Would not it be faster not to enumerate for large mailboxes (30-40GB - Maildir)? Is it possible to add a switch, to select single user expunge behavior? ref: http://www.mail-archive.com/dovecot@dovecot.org/msg32322.html 2. Also. expunge does not appear to remove empty mailboxes, is this a bug or intentional? If intentional, why? Any way to automated removal of empty mailboxes? Thank you KuiZ

Hi all, I was wondering if any of you had configured a Mailbox with >= 5GB of space with LDA indexing enabled on it. I'm trying to understand the limits to Dovecot (if there are any) regarding maildirs/indexes max size. Reading in the documentation i didn't found anything concerning this issue. Any experience with this? Emmanuel Gonzalez Carmona

[Dovecot] Differences between IPv4 and IPv6 authentication
by Tony Meyer 02 Nov '10

02 Nov '10

Hi, I have Dovecot listening on both IPv4 and IPv6, and can connect on both interfaces, but cannot authenticate over IPv6, using exactly the same credentials as IPv4. I assumed that the same authentication mechanisms would be used, regardless of the protocol being used - are there differences somewhere? For example: ~$ telnet server1.teststable.simplyspamfree.com 143 Trying 2a01:4f8:100:12c1:bc:28:b2:34... Connected to server1.teststable.simplyspamfree.com.

[Dovecot] fts_solr on debian lenny dovecot 1.2.15
by a＠test123.ru 02 Nov '10

02 Nov '10

Hello, I cannot run FTS SOLR engine. OS is debian lenny. I re-compiled debian package (from backports) with --with-solr option. Dovecot loads fts_solr plugin. I know that it loads plugin because if I remove lib21_fts_solr_plugin.so, dovecot does not start. But it does not attempt to communicate with SOLR. Simple check: stop solr tomcat, and open 8080 port in netcat: $nc -l -p 8080 dovecot never tries to connect to 8080 when I search message by IMAP. I removed indexes, it did not help.

Hello We are in (random) troubles with some emails that contains word and excel attachements ( others attachements are OK ) I don't really think Dovecot is implied in this trouble but I want to be sure ... The problem is users cannot open attachements from their clients ( thunderbird 3.1 ) it stays in "download" mode until timeout. Maybe there is a Dovecot's workaround to solve that boring problem ? Thank you

[Dovecot] Linux Bootup: Dovecot Failure
by Christopher Metter 01 Nov '10

01 Nov '10

Hi there! Im using a dovecot system in combination with postfix(with dovecot lda) and ldap. Till today it ran well, but before switching to live, i did some system updates and at the reboot following message occured: Starting IMAP/POP3 mail server: dovecoUnexpected first line <localhost: timed out, nothing received> (First it says: "Starting IMAP/POP3 mail server: dovecot ", but then something fails and overrides the "t" of dovecot with "Unexpected.... ") I don't know when this error occured first, but it only goes away if i delete dovecot from autostart at bootup (by renaming dovecot-file in /etc/rc2.d/ ) No error shown in /var/log/mail.* or syslog Apart from showing this message, system is running perfectly. Users can login, receive their mail and produce new mail-traffic with postfix ;) ATM i really dont know what to do, im near switching to live status of this system and that message is annoying me. Didnt find any information on the net. Hope someone on this list can give an helpful advice Dovecot version: 1.2.15 Greetings from Germany, Christopher Metter dovecot -n: http://nopaste.info/0447cd09ba.html Boot log: http://nopaste.info/index.html

[Dovecot] Mailing lists in Dovecot?
by Peter Reinhold 01 Nov '10

01 Nov '10

Hi all, I was wondering if anyone could recommend a simple mailing list manager that plays well with a Postfix/Dovecot setup, with virtual domains? It really just has to be very simple, basically, an alias would work, if I could rewrite the sender address/name, and I don't really need the possibility for users to subscribe via e-mail based commands. I've looked at the XEXEC plugin as a possible method of doing this, via some Perl perhaps, anyone has any experience using this they would like to share? Mvh, Peter Reinhold / peter(a)reinhold.dk

[Dovecot] auth child abort - "Requested NTLM scheme, but we have only SSHA256"
by LEVAI Daniel 01 Nov '10

01 Nov '10

Hi! I noticed these messages in my logs. It seems that the user checked the "encrypted password" in her outlook or something, and wants NTLM auth. I'm storing all the passwords as SSHA256, and when the user tries to auth, this happens: => dovecot.info auth: Info: password(<username>,<user_ip>): Requested NTLM scheme, but we have only SSHA256 auth: Debug: sql(<username>,<user_ip>): query: SELECT username AS user, password, home AS userdb_home, uid AS userdb_uid, gid AS userdb_gid, userdb_import AS userdb_userdb_import FROM userdb WHERE auth_username = '<username>' AND login = 'enabled' => dovecot.log auth: Error: sql(<username>,<user_ip>): Multiple password values not supported auth: Panic: file passdb-sql.c: line 113 (sql_query_callback): assertion failed: (password == NULL || scheme != NULL) master: Error: service(auth): child 10679 killed with signal 6 (core not dumped - set service auth { drop_priv_before_exec=yes }) Is this an error condition if I store the password in a different scheme than what user is requesting?

[Dovecot] Testing pop3/imap4 and mdbox corrupted indexes?
by Odhiambo Washington 01 Nov '10

01 Nov '10

I have two questions: 1. What method/tool (other than a MuA) can I use to test my Dovecot setup from Windows CLI when ssl is enabled? I have tried connecting to to the pop3/imap4 services from a Windows PC but here is what I get: [pop3] +OK Dovecot-2.0-sis ready. user wash(a)domain.co.ke -ERR Plaintext authentication disallowed on non-secure (SSL/TLS) connections. [imap4] OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS LOGINDISABLED AUTH=DIGEST-MD5] Dovecot-2.0-sis ready. login wash(a)domain.co.ke S3ecreat BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. NO [PRIVACYREQUIRED] Plaintext authentication disallowed on non-secure (SSL/TLS) connections. 2. When mdbox indexes are corrupted, are they automatically repaired/rebuilt or must I specify this in the configuration? How long does it take? Nov 01 12:08:04 pop3(wash(a)domain.co.ke): Error: Corrupted dbox file /var/spool/virtual/domain.co.ke/wash/mdbox/storage/m.1 (around offset=1941): Ex t refs metadata corrupted: 3861 783856 75/80/75805ed445f1b8b31508dba8d86280a37a74aec1-fabfb11f9f80654ced090000dcbe1dcb Nov 01 12:08:04 pop3(wash(a)domain.co.ke): Error: Corrupted dbox file /var/spool/virtual/domain.co.ke/wash/mdbox/storage/m.1 (around offset=1941): ui d=5 points to broken data at offset=1911 Nov 01 12:08:04 pop3(wash(a)domain.co.ke): Warning: mdbox /var/spool/virtual/ domain.co.ke/wash/mdbox/storage: rebuilding indexes When I connect using outlook, I see this on Outlook: Task 'wash(a)domain.co.ke - Receiving' reported error (0x800CCC90) : 'Your incoming (POP3) e-mail server has reported an internal error.

[Dovecot] Testing simscan

I am pulling my hair out, i think I know what is wrong - i just cant find out how to fix it. Using Debian - lenny it appears that the auth process - is not looking for / seeing the proper file or database for the lookup. i would like it to point to the cdb file stored ~/domains/%d/ <---- assuming the %d = domains - and the file would then be vpasswd.cdb...... Let me know if i need to post anything else to help. 2010-10-30 15:35:58.147617500 auth: Debug: Loading modules from directory: /usr/local/lib/dovecot/auth 2010-10-30 15:35:58.147852500 auth: Debug: auth client connected (pid=27491) 2010-10-30 15:35:58.149434500 imap-login: Warning: SSL: where=0x10, ret=1: before/accept initialization [70.62.148.223] 2010-10-30 15:35:58.149436500 imap-login: Warning: SSL: where=0x2001, ret=1: before/accept initialization [70.62.148.223] 2010-10-30 15:35:58.149437500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read client hello A [70.62.148.223] 2010-10-30 15:35:58.149437500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write server hello A [70.62.148.223] 2010-10-30 15:35:58.149438500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write certificate A [70.62.148.223] 2010-10-30 15:35:58.149444500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write server done A [70.62.148.223] 2010-10-30 15:35:58.149445500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 flush data [70.62.148.223] 2010-10-30 15:35:58.149446500 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [70.62.148.223] 2010-10-30 15:35:58.149446500 imap-login: Warning: SSL: where=0x2002, ret=-1: SSLv3 read client certificate A [70.62.148.223] 2010-10-30 15:35:58.177505500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read client key exchange A [70.62.148.223] 2010-10-30 15:35:58.177507500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 read finished A [70.62.148.223] 2010-10-30 15:35:58.177508500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write change cipher spec A [70.62.148.223] 2010-10-30 15:35:58.177508500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 write finished A [70.62.148.223] 2010-10-30 15:35:58.177509500 imap-login: Warning: SSL: where=0x2001, ret=1: SSLv3 flush data [70.62.148.223] 2010-10-30 15:35:58.177532500 imap-login: Warning: SSL: where=0x20, ret=1: SSL negotiation finished successfully [70.62.148.223] 2010-10-30 15:35:58.177533500 imap-login: Warning: SSL: where=0x2002, ret=1: SSL negotiation finished successfully [70.62.148.223] 2010-10-30 15:35:58.287127500 auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=172.16.150.30 rip=70.62.148.223 lport=993 rport=46817 2010-10-30 15:35:58.287210500 auth: Debug: client out: CONT 1 2010-10-30 15:35:58.307138500 auth: Debug: client in: CONT 1 AHJ4YmF1ZXJAcGhhdGFuaGFwcHkuY29tADUxNjIzMQ== 2010-10-30 15:35:58.307139500 auth: Debug: vpopmail(rxbauer(a)phatanhappy.com,70.62.148.223): lookup user=rxbauer domain=phatanhappy.com 2010-10-30 15:35:58.307140500 auth: Info: vpopmail(rxbauer(a)phatanhappy.com,70.62.148.223): unknown user 2010-10-30 15:36:00.308541500 auth: Debug: client out: FAIL 1 user=rxbauer(a)phatanhappy.com 2010-10-30 15:36:00.379057500 auth: Debug: client in: AUTH 2 PLAIN service=imap secured lip=172.16.150.30 rip=70.62.148.223 lport=993 rport=46817 resp=AHJ4YmF1ZXJAcGhhdGFuaGFwcHkuY29tADUxNjIzMQ== 2010-10-30 15:36:04.380615500 auth: Debug: vpopmail(rxbauer(a)phatanhappy.com,70.62.148.223): lookup user=rxbauer domain=phatanhappy.com 2010-10-30 15:36:04.380707500 auth: Info: vpopmail(rxbauer(a)phatanhappy.com,70.62.148.223): unknown user 2010-10-30 15:36:06.380535500 auth: Debug: client out: FAIL 2 user=rxbauer(a)phatanhappy.com dovecot --version 2.0.6 dovecot -n # 2.0.6: /usr/local/etc/dovecot/dovecot.conf doveconf: Warning: NOTE: You can get a new clean config file with: doveconf -n > dovecot-new.conf doveconf: Warning: Obsolete setting in /usr/local/etc/dovecot/conf.d/10-mail.conf:350: namespace private {} has been replaced by namespace { type=private } # OS: Linux 2.6.26-2-686 i686 Debian 5.0.6 auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = plain debug_log_path = /dev/stderr default_client_limit = 2000 default_process_limit = 200 default_vsz_limit = 512 M first_valid_uid = 100 hostname = mail.cyborspace.com info_log_path = /dev/stderr log_path = /dev/stderr log_timestamp = mail_location = maildir:~/Maildir namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { driver = vpopmail } postmaster_address = postmaster(a)cyborspace.com service imap-login { inet_listener imap { address = 127.0.0.1 port = 143 } inet_listener imaps { address = 172.16.150.30 port = 993 ssl = yes } } service lmtp { unix_listener lmtp { mode = 0666 } } service pop3-login { inet_listener pop3 { address = 127.0.0.1 port = 110 } inet_listener pop3s { address = 172.16.150.30 port = 995 ssl = yes } } ssl_cert = </var/qmail/control/servercert.pem ssl_key = </var/qmail/control/servercert.pem userdb { driver = vpopmail } verbose_proctitle = yes verbose_ssl = yes A A A A A
