[Dovecot] Quota not showing properly in webmail
by Eden 29 Apr '08

29 Apr '08

Hi I have a virtual users system using postfix / mysql / dovecot. Everything is working like a charm except for the quota display on webmail systems. It is working properly but showing GB instead of MB. For example. If I create a user with 100MB of quota and send him 50MB of mail, squirrelmail and roundcubemail display 50MB of 100GB If I create another user with 20MB quota and send him 10MB of mail, squirrelmail and roundcube dipslay 10MB of 20GB. if I send 50MB more I get the quota error msg I should get. So everything is workign but its displaying incorrectly. At first I though it was squirrelmail`s fault but it happens with roundcube as well, since both get their quota info from the imap server than I think its dovecot. I`m using Debian 4.0 This is the output of the --version and the -n dovecot commands. qgalvao-dns:/# dovecot --version 1.0.rc15 qgalvao-dns:/var/log# dovecot -n # /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log log_timestamp: %Y-%m-%d %H:%M:%S protocols: imap imaps pop3s pop3 listen(default): *:143 listen(imap): *:143 listen(pop3): *:110 ssl_listen(default): *:993 ssl_listen(imap): *:993 ssl_listen(pop3): *:995 disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable(default): /usr/lib/dovecot/imap-login login_executable(imap): /usr/lib/dovecot/imap-login login_executable(pop3): /usr/lib/dovecot/pop3-login first_valid_uid: 150 last_valid_uid: 150 mail_privileged_group: mail mail_location: maildir:/vmail/%n@%d maildir_copy_with_hardlinks: yes mail_executable(default): /usr/lib/dovecot/imap mail_executable(imap): /usr/lib/dovecot/imap mail_executable(pop3): /usr/lib/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): mail_plugin_dir(default): /usr/lib/dovecot/modules/imap mail_plugin_dir(imap): /usr/lib/dovecot/modules/imap mail_plugin_dir(pop3): /usr/lib/dovecot/modules/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: mechanisms: login plain digest-md5 cram-md5 user: nobody verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: sql args: /etc/dovecot/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 432 user: vmail group: mail

[Dovecot] Connection problems using dovecot proxy
by Adrian Wojcicki | Unternehmensberatung Wojcicki 29 Apr '08

29 Apr '08

Hi Maybe somebody could help me with the following problem: I have set up a dovecot imap proxy in the dmz and a dovecot imap server in the intranet. Both in version 1.05. Now, while this setup works using Thunderbird, iPhone, etc. I have problems connecting using a Samsung Qbowl. It simply aborts with a connection error. Using the same setup but bypassing the proxy and connecting to the imap server directly does work for the phone. Logs on both servers don't show any errors. There is simply a "Info: IMAP(test): Connection closed" at the end. I enabled the rawlogs on the imap server but they don't long anything (They do log access from other imap clients but nothing from the phone). Could somebody point me into a direction where to look next? LOGS: Dovecot proxy: # 1.0.5: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log ssl_cert_file: <pathToCert> ssl_key_file: <pathToCert> disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_debug: yes auth default: cache_size: 4096 cache_ttl: 7200 debug: yes passdb: driver: sql args: /etc/dovecot/sql.conf userdb: driver: static args: static uid=5000 gid=5000 home=/dev/null dovecot: Apr 23 15:42:45 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=192.168.3.200 rip=80.187.64.167 resp=<hidden> dovecot: Apr 23 15:42:45 Info: auth(default): cache(test,80.187.64.167): hit dovecot: Apr 23 15:42:45 Info: auth(default): cache(test,80.187.64.167): NULL password access dovecot: Apr 23 15:42:45 Info: auth(default): client out: OK 1 user=test host=192.168.0.205 destuser=test nologin proxy pass=<hidden> dovecot: Apr 23 15:42:45 Info: imap-login: proxy(test): started proxying to 192.168.0.205:143: user=<test>, method=PLAIN, rip=80.187.64.167, lip=192.168.3.200 dovecot: Apr 23 15:42:45 Info: imap-login: proxy(test): disconnecting 80.187.64.167 Dovecot server: # 1.0.5: /etc/dovecot/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot//login login_executable: /usr/lib/dovecot/imap-login mail_location: maildir:/home/%u/.maildir mail_debug: yes mail_executable: /usr/lib/dovecot/rawlog /usr/lib/dovecot/imap auth default: debug: yes passdb: driver: passwd-file args: /etc/dovecot/passwd userdb: driver: static args: uid=1001 gid=100 home=/home/%u dovecot: Apr 23 15:42:45 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=192.168.0.205 rip=192.168.2.1 resp=<hidden> dovecot: Apr 23 15:42:45 Info: auth(default): passwd-file(test,192.168.2.1): lookup: user=test file=/etc/dovecot/passwd dovecot: Apr 23 15:42:45 Info: auth(default): client out: OK 1 user=test dovecot: Apr 23 15:42:45 Info: auth(default): master in: REQUEST 6 11785 1 dovecot: Apr 23 15:42:45 Info: auth(default): master out: USER 6 test uid=1001 gid=100 home=/home/test dovecot: Apr 23 15:42:45 Info: imap-login: Login: user=<test>, method=PLAIN, rip=192.168.2.1, lip=192.168.0.205 dovecot: Apr 23 15:42:45 Info: IMAP(test): Effective uid=1001, gid=100, home=/home/test dovecot: Apr 23 15:42:45 Info: IMAP(test): maildir: data=/home/test/.maildir dovecot: Apr 23 15:42:45 Info: IMAP(test): maildir: root=/home/test/.maildir, index=/home/test/.maildir, control=, inbox= dovecot: Apr 23 15:42:45 Info: IMAP(test): Connection closed

[Dovecot] Imap sent folder sometimes dosen't get updated in dovecot-1.1-rc3(+some current hg patches)
by Diego Liziero 29 Apr '08

29 Apr '08

Yes, again, some sent emails don't get copied to sent folder. This time I get the following error: Error: IMAP(username): UIDs broken with partial sync in mbox file /maildir/username/Sent This happened at least with thunderbird and with evolution. Dovecot is running on vith fcntl locking on Centos5, sendmail should use fcntl, too. Filesystem is ext3 on drbd partition. After a grep vith dovecot.log I see the same error message also with other imap folders as well (mainly Trash imap folder). Should I try to get a rawlog? Regards, Diego.

[Dovecot] icedove update
by Karl Schmidt 29 Apr '08

29 Apr '08

Something came up that Confounded problems in my move from UW-imap to dovecot. I found a problem with the new icedove update in Debian lenny when moving from 1.5.0.13+1.5.0.14b.dfsg1-0etch1 to 2.0.0.9-3 that could look like a dovecot issue. Icedove runs for a while but eventually quits updating the displayed email, yet appears to be working and busy trying to get messages from the server. I think it is related to message filters, but not sure. The fix was to move .mozilla-thundrebird somewhere and restart icedove and create a new profile. There may be a more elegant fix. ---------------------------------------------------------------- Karl Schmidt EMail Karl(a)xtronics.com Transtronics, Inc.

[Dovecot] sieve doesn't sift yet
by Colin Brace 28 Apr '08

28 Apr '08

Hi all, I am having difficulty getting sieve working. I created a simple set of rules which I've validated on the sieve-php page at SF. I placed this file, .dovecot.sieve, in the root of my maildir, which I understand is the default location. I also created a logfile in /var/log, but nothing has gotten written to it yet. Here is my configuration: $ sudo dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot info_log_path: /var/log/dovecot.info ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_gid: 0 mail_access_groups: mail mail_location: maildir:/var/spool/vmail/%n mail_debug: yes pop3_uidl_format: %08Xu%08Xv auth default: verbose: yes passdb: driver: passwd-file args: /usr/local/etc/dovecot-passwd userdb: driver: passwd userdb: driver: static args: uid=vmail gid=vmail home=/var/spool/vmail/%n What piece of the puzzle am I still missing?

[Dovecot] Public Namespace + ACLs + virtual users
by Fintec 28 Apr '08

28 Apr '08

g'day! I'd just like to share my experience with public namespace and ACLs. I know this has been discussed a number of times in the past, but there were no definite answers. dovecot version i'm using: 1.0.13 Got a public namespace setup in dovecot.conf as follows: namespace public { separator = . prefix = Public_Folders. location = maildir:/home/vmail/domains/% d/Public_Folders:CONTROL=/home/vmail/domains/%d/% n/Public_Folders/support:INDEX=/home/vmail/domains/%d/% n/Public_Folders/index hidden = no } In it's own right this works just fine and it's been in use for some time now. But we need some control over who can access and delete things. So I had a go at configuring ACLs. I configured global ACLs, because as far as I can tell, per directory ACLs seem to be ignored. Once configured global ACLs work fine, except for 1 major issue; users cannot create new folders because ACLs do not get propagated (are not applied to the subfolders). If an user attempts to create a new (sub)folder, the folder is created on the filesystem however email client throws an error and the folder is inaccessible to the user as there is no ACL for it. Any pointers how to get around this? Has this been dealt with in v1.1? Regards Natko Muzina

Hi Johannes. I wanted to try out the antispam plugin for a Dovecot 1.1 install, only to learn that 1.1 is actually not supported. Are there any plans to remedy this? If not, is it known how much effort is required? (i.e. could I do it myself?). Thanks, Anders.

[Dovecot] Does a script exist to fix broken maildir timestamps?
by drbob 26 Apr '08

26 Apr '08

Hello, When I upgraded to dovecot (changing servers at the same time) in November last year I copied the maildirs from my old server without using the -p option to preserve timestamps! Since my mail client displays the email dates based on the Date header rather than the imap "internaldate" I didn't notice the problem until today when I tried to migrate an account to gmail using imapsync and found that all emails prior to November display the wrong date in the web interface (they show the date they were copied in November). I feel very silly. Before I go try to hack together a script which parses all my older email files and changes the timestamps to the time recorded in the "Date:" header, does anyone know if robust, tested version of such a script is alrady available? Would correcting the timestamps in this way cause any problems for dovecot (e.g in the index files)? Thanks in advance for any help. drbob NB In my googling for a solution to this problem I found this hack to imapsync which would rewrite the "internaldate" based on the date header during a sync. Whilst I'd rather fix the timestamps that are the source of the problem, it may be useful for others finding this post in the future, see: http://www.zimbra.com/forums/installation/237-received-date-appears-incorre…

[Dovecot] Mixing LDAP and static
by Anders 25 Apr '08

25 Apr '08

I want to read quota size from LDAP, but I have a static value for home. How can I mix these? Right now, I have this LDAP configuration: user_attrs = uid=home=/var/mail/vhosts/%d/%n,gosaMailQuota=quota_rule=*:bytes=%$M which works fine, but looks up the uid attribute needlessly, and is not scalable: I have to pick a different, always-existing LDAP attribute for each static extra field that I want to set. Is there some LDAP configuration syntax like the SQL "SELECT '/var/...' AS home" ? Thanks, Anders.

[Dovecot] 1.0.5: many pop3-login processes?
by Alan Ferrency 25 Apr '08

25 Apr '08

Hello, We are running dovecot 1.0.5 on a test server, with FreeBSD 6.2 (though I have noticed the same problem since dovecot versions in the 0.99 range). We don't have very many simultaneous pop/imap users, but we have a proliferation of pop3-login processes. Currently we have 128 such processes. We have 11 imap-login processes, but only a few actual imap processes running. Is this normal? Can we stop it? Is anyone else successfully running dovecot on FreeBSD 6.2? Thanks for your help.

[Dovecot] Problem with Dovecot Delivery Agent, Extra "From" lines and mbox
by Hokan 25 Apr '08

25 Apr '08

When an mbox email contains a line that looks like a "Mail" header it should be quoted (per RFC 4155). Sendmail's delivery agent does this, as does Procmail delivery agent. Dovecot deliver does not do this. Example line, with ">" quote: >From hokan(a)hokan.org Thu Mar 8 17:28:01 2008 When reading email (IMAP) that contains such an unquoted line, the email abruptly ends before the "Mail" line. There may (or may not) appear another email (visible to the client) that contains the rest of the email. -- Hokan MEnet, a wholly owned subsidiary of Enet System Administrator Department of Mechanical Engineering hokan(a)me.umn.edu Institute of Technology 612.626.9800 University of Minnesota

[Dovecot] Authentication: Dovecot -> Vpopmail - > MySQL with one table per domain
by James Nordstrom 25 Apr '08

25 Apr '08

Hi All, I am using Dovecot 1.0.13 with Vpopmail (Qmail Toaster current) backed by MySQL with one table per domain (--disable-many-domains) . What I cannot figure out is how to have Dovecot authenticate to Vpopmail when Vpopmail uses one table per domain. Basically I need dynamic SQL in the Dovecot-sql.conf file. Currently I have: password_query = select pw_clear_passwd as password from domainname_com where pw_name = '%n' I need something like password_query = select pw_clear_passwd as password from %d where pw_name = '%n' Where %d is the name of the table. I can't use the exact domain name at it will not match the vpopmail format domainname_com. I would be happy to use some sort of sting builder but and not sure what my options are in the .conf file.

[Dovecot] sieve header :matches for multiline header

RFC3028 say: Folding of long header lines (as described in [IMAIL] 3.4.8) is removed prior to interpretation of the data. The folding syntax (the CRLF that ends a line plus any leading whitespace at the beginning of the next line that indicates folding) are interpreted as if they were a single space. But it seems to be not true for dovecot-sieve-1.0.2 for header Received: from example.ru (example.ru [192.168.105.14]) by myserver (Postfix) with ESMTP id D4DA5D85927 This sieve test work: header :matches "Received" "from *by myserver (Postfix) with ESMTP id *" But this test not work, while should also work according to RFC: header :matches "Received" "from * by myserver (Postfix) with ESMTP id *" -- WBR, Anton Yuzhaninov

[Dovecot] ACLs generating plugin problems.
by "Fábio M. Catunda" 25 Apr '08

25 Apr '08

Hi! I'm trying to use an ACL to avoid deletion of messages that are inside .Trash folder, the ACL is already working very well, the problem that I'm facing is that even if the message is not deleted, mail_log logs that it has been deleted. Also, in some cases part of the lazy_expunge code is executed too, but sometimes I just dont know where the message is, thats weird. I erased deleted and expunged folders, then I deleted a message, It hasn't been deleted, but "deleted" and "expunged" folders has been created. Anyway, I would like to know if there is a way to stop plugin execution when an ACL matches. Thanks a lot.

[Dovecot] alert function, V2
by Stewart Dean 25 Apr '08

25 Apr '08

I guess the alert function is not part of the spec, because it appears to be unimplemented in Dovecot, even though most clients implement it. Timo, I would hope this would be easy to implement, and it's functionality that will be valuable to every installation. Here's why. America recently had the tragedy of a shooting rampage on a large university campus (yes, America should do something about the violence and free access to guns in our culture/society). What was worse was that, due to the lack of an emergency notification process, some 20+ people died needlessly. Now all college and university administration are scrambling to set up emergency notification processes. Our first take on this is a massive all-hands mailing list, but a) best case, it would take 15 minutes (and as much as an hour) to get to everybody's mailbox. b) users would have to read through their mail and stumble on the message What's needed is an "in-your-face" unavoidable alert, and the UWIMAP alert functionality provides this. As I recall, you touch just about anything in your IMAP client and there's a popup message in the middle of the client IMAP window...and it happens repeatedly. We tried it back 3-4 years ago and found it too annoying to use. For this purpose, it's perfect. The wy UWIMAP did it, the presence of the file /etc/imapd.alert triggers it, and the text in that file is transmitted to the client. The message has to be short, a one-liner for a small popup window, but this could be a pointer to a shared system message folder. Of course, DC could sense the activation of the alert in some other fashion that the presence of a file. Ideally, whatever activates the alert function should be able to be turned on remotely; I had in mind to do it using a mail aliases that is a pipe to a executable...

It seems to be another index-related corruption issue (as removing "dovecot.index" for INBOX fixed it); Using POP3: dovecot: Apr 09 10:28:14 Warning: POP3(USERNAME): Maildir /mail/USERNAME/Maildir: UIDVALIDITY changed (1145576765 -> 1207677483) dovecot: Apr 09 10:28:14 Panic: POP3(USERNAME): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) dovecot: Apr 09 10:28:14 Error: POP3(USERNAME): Raw backtrace: pop3 [0x80c04e4] -> pop3 [0x80c013c] -> pop3 [0x808eb9a] -> pop3(index_mailbox_set_recent_seq+0x3e) [0x808ebde] -> pop3(maildir_sync_index+0x923) [0x8064173] -> pop3 [0x8062e22] -> pop3(maildir_storage_sync_init+0x58) [0x8062f98] -> pop3(mailbox_sync+0x1f) [0x80912af] -> pop3(client_create+0x1de) [0x805968e] -> pop3(main+0x403) [0x805b503] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x707dec] -> pop3 [0x8058e71] dovecot: Apr 09 10:28:14 Error: child 28169 (pop3) killed with signal 6 Using IMAP (after "SELECT INBOX"): dovecot: Apr 09 10:56:31 Warning: IMAP(USERNAME): Maildir /mail/USERNAME/Maildir: UIDVALIDITY changed (1145576765 -> 1207677483) dovecot: Apr 09 10:56:31 Panic: IMAP(USERNAME): file index-sync.c: line 39 (index_mailbox_set_recent_uid): assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) dovecot: Apr 09 10:56:31 Error: IMAP(USERNAME): Raw backtrace: imap [0x80cd564] -> imap [0x80cd1bc] -> imap [0x809b32a] -> imap(index_mailbox_set_recent_seq+0x3e) [0x809b36e] -> imap(maildir_sync_index+0x923) [0x8070903] -> imap [0x806f5b2] -> imap(maildir_storage_sync_init+0x58) [0x806f728] -> imap(mailbox_sync+0x1f) [0x809da3f] -> imap(cmd_select_full+0xd5) [0x805dec5] -> imap(cmd_select+0x19) [0x805e069] -> imap [0x805f799] -> imap [0x805f827] -> imap [0x805ffb5] -> imap(client_input+0x5e) [0x80601ce] -> imap(io_loop_handler_run+0x100) [0x80d4d50] -> imap(io_loop_run+0x28) [0x80d42e8] -> imap(main+0x4ac) [0x8067bdc] -> /lib/libc.so.6(__libc_start_main+0xdc) [0x125dec] -> imap [0x8059d61] dovecot: Apr 09 10:56:31 Error: child 7057 (imap) killed with signal 6 We made a copy of the mailbox and index in case any further testing would be helpful, -Rich

[Dovecot] Rare problem with Indexes?
by richs＠whidbey.net 25 Apr '08

25 Apr '08

We've been running 1.1 rc3 now for about a month, and overall it's been very fast and stable. There is however an Index-related problem that keeps cropping up which prevents a user from accessing their mailbox until their Indexes are manually removed. Somehow, an Index becomes problematic, and Dovecot hangs forever when the mailbox is accessed. It manifests when a user logs in and issues a "SELECT INBOX", or "GETQUOTAROOT" when "maildirsize" needs rebuilding. When Dovecot hangs, no data is returned and no further commands are accepted, and the daemon must be killed. We see no errors in the logs, but have yet to catch the problem with "mail_debug" enabled. We're using NFS with Maildir's and these related options: mail_location = maildir:/mail/%Lu/Maildir:INDEX=/mail/%Lu/Cache mmap_disable = yes mail_nfs_storage = yes mail_nfs_index = yes mail_drop_priv_before_exec = yes mail_cache_min_mail_count = 128 mailbox_idle_check_interval = 5 maildir_stat_dirs = yes maildir_copy_with_hardlinks = yes maildir_copy_preserve_filename = no Has anyone else run across the need to purge Indexes manually? Could this be unrecoverable Index corruption, or a locking issue? We've made a copy of the mailbox when the problem occurs. However, when we test it later, Dovecot re-builds the "dovecot.index" file itself just fine, and functions normally. We plan to "mail_debug" when this happens next to see if we can get more information. Thanks! -Rich

[Dovecot] Dovecot features
by Phan Thanh Diện 25 Apr '08

25 Apr '08

Hi, We would like to switch from courier-imap to dovecot. I have installed dovecot on a machine running FreeBSD 6.3 and now testing it. My questions are below: 1. Can I configure dovecot to delete all files that are older, say 10 days, from defined mail boxes (for example Trash or Spam). 2. After I access mail box (using web mail squirrel imap) all emails moved from 'new' directory to 'cur'. Then messages are not accessible for pop3. Such behavor doesn't occur with courier-imap. Can I force dovecot to behave like courier-imap? Many thanks for help. Dien Phan

[Dovecot] 1.1 a major improvement
by Cor Bosman 24 Apr '08

I recently switched one of our 30 imap servers to 1.1RC4 from 1.0.x, and the difference is huge. The load on the server dropped from 5+ to 0.3 or so. This means there is no more io waiting going on. Thats on FreeBSD 6.2. Great work Timo! Cor

[Dovecot] dovecot: Fatal: IMAP(user2): write(event_pipe) failed: Bad file descriptor
by Mart Pirita 24 Apr '08

Hello. Since I upgraded few months ago from version 1.0 to 1.1 (right now using v1.1.rc4) in logs for some users only (but in different servers) I noticed errors: dovecot: Fatal: IMAP(user2): write(event_pipe) failed: Bad file descriptor dovecot: Fatal: IMAP(user3): write(event_pipe) failed: Bad file descriptor So only for some imap users. And in different servers. And this error happens suddenly, I already tried to delete delete cache and index files. However the users themselves haven't noticed any problems. Shall I just ignore these errors on what? Configuration is quite simple: dovecot -n # 1.1.rc4: /etc/dovecot.conf protocols: imaps pop3 pop3s ssl_parameters_regenerate: 0 disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_log_format_elements: %u [%r] %m %c mail_max_userip_connections(default): 90 mail_max_userip_connections(imap): 90 mail_max_userip_connections(pop3): 9 maildir_copy_preserve_filename: yes mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 imap_client_workarounds(default): outlook-idle netscape-eoh tb-extra-mailbox-sep delay-newmail imap_client_workarounds(imap): outlook-idle netscape-eoh tb-extra-mailbox-sep delay-newmail imap_client_workarounds(pop3): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_logout_format(default): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(imap): top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_logout_format(pop3): bytes=%i/%o, del=%d/%m, size=%s auth default: cache_size: 1024 failure_delay: 3 passdb: driver: pam args: cache_key=%u%r%s * userdb: driver: passwd -- Mart
