[Dovecot] Dovecot 1.0.7 domain variable
by elliott＠n.localhost 13 May '09

13 May '09

Hi all, Thanks in advance for any help! I'm trying to configure Dovecot to pull emails from Postfix virtual mailbox domain Maildirs under /var/mail/vhosts/<domain>/<username>. I've set mail_location as such in dovecot.conf: mail_location = maildir:/var/mail/vhosts/%d/%n but from debug output I see the domain is blank: dovecot: May 10 20:49:25 Info: IMAP(elliott): maildir: data=/var/mail/vhosts//elliott I've set elliott(a)n.0o0.bz as my username in Outlook so it is sending the domain (and changed auth_username_format to "auth_username_format = %n" so authentication works fine) Why is %d blank here? Anything else to check?? I'm at a loss. Thanks! -elliott-

[Dovecot] New messages notification - (IMAP PUSH?)
by Proskurin Kirill 13 May '09

13 May '09

Hello all. I have strange problem. As I understand IMAP use server2client command to tell what new email is arrived. So - all was good, but few weeks ago I notice what my thunderbird not show new messages. I think it was local problem(I switch distro what day) but soon my email clients what uses mostly Outlook-2007-SP1 start to confirm this problem. What can it be and how can I fix it? I use Dovecot on FreeBSD-7.1 #pkg_info | grep dovecot dovecot-1.1.11 dovecot-managesieve-0.10.5 dovecot-sieve-1.1.6 #dovecot -n # 1.1.11: /usr/local/etc/dovecot.conf # OS: FreeBSD 7.1-RELEASE-p3 i386 ufs base_dir: /var/run/dovecot/ log_path: /var/log/dovecot/dovecot.log info_log_path: /var/log/dovecot/dovecot-debug.log protocols: imap imaps pop3 pop3s managesieve listen(default): * listen(imap): * listen(pop3): * listen(managesieve): *:2000 ssl_ca_file: /usr/local/etc/certs/GlobalSignCA.crt ssl_cert_file: /usr/local/etc/certs/fxclub_org.crt ssl_key_file: /usr/local/etc/certs/fxclub_org.key ssl_cipher_list: ALL:!LOW:!SSLv2 login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login login_executable(managesieve): /usr/local/libexec/dovecot/managesieve-login login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no login_greeting_capability(managesieve): no login_process_size: 128 login_processes_count: 20 login_max_processes_count: 512 mail_max_userip_connections(default): 256 mail_max_userip_connections(imap): 256 mail_max_userip_connections(pop3): 20 mail_max_userip_connections(managesieve): 10 verbose_proctitle: yes first_valid_gid: 0 mail_privileged_group: mail mail_uid: dmail mail_gid: dmail mail_location(default): maildir:/var/spool/dovecot/domains/%d/%n/ mail_location(imap): maildir:/var/spool/dovecot/domains/%d/%n/ mail_location(pop3): maildir:/var/spool/dovecot/domains/%d/%n/ mail_location(managesieve): mail_debug: yes mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_executable(managesieve): /usr/local/libexec/dovecot/managesieve mail_process_size: 512 mail_plugins(default): quota imap_quota autocreate mail_plugins(imap): quota imap_quota autocreate mail_plugins(pop3): quota mail_plugins(managesieve): mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 mail_plugin_dir(managesieve): /usr/local/lib/dovecot/managesieve imap_client_workarounds(default): delay-newmail tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail tb-extra-mailbox-sep imap_client_workarounds(pop3): imap_client_workarounds(managesieve): pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh pop3_client_workarounds(managesieve): sieve_storage(default): sieve_storage(imap): sieve_storage(pop3): sieve_storage(managesieve): % sieve(default): sieve(imap): sieve(pop3): sieve(managesieve): ~/.dovecot.sieve auth default: mechanisms: plain login user: dovecot-auth username_format: %Lu verbose: yes worker_max_count: 100 passdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf userdb: driver: ldap args: /usr/local/etc/dovecot-ldap.conf socket: type: listen client: path: /var/run/dovecot/auth-client mode: 432 user: exim master: path: /var/run/dovecot/auth-master mode: 384 user: dmail plugin: quota: maildir quota_rule: *:storage=1024M quota_rule2: Trash:storage=1256M quota_rule3: SPAM:ignore quota_warning: storage=80%% /usr/local/bin/quota-warning.sh 80 quota_warning2: storage=95%% /usr/local/bin/quota-warning.sh 95 autocreate: Trash autocreate2: Sent autocreate3: Spam autosubscribe: Trash autosubscribe2: Sent autosubscribe3: Spam -- Best regards, Proskurin Kirill

[Dovecot] Dovecot shared quota with Maildir
by Jorgen Lundman 13 May '09

13 May '09

Hello list, We are in the process of exploring the idea of moving from UFS with fs-quota to using softquotas in Dovecot (probably Maildir type, stored in LDAP, all ontop of NFS). I have it setup, and it works rather well so far. But there is one situation we can currently support, which I can not see a solution for with soft-quotas. Generally customers get 1 email, with 1 quota. But it is also possible for customers to get 1 quota, but create multiple mail accounts, all sharing the same quota. This is done by using the same UID for each account when using fs-quota. (It is not that each account gets a fraction of the quota, but that all accounts add up to the one quota). Is this still possible to do with soft-quotas. To share one set. Dovecot would have to go count files in multiple mail-directories so I would guess no.

[Dovecot] dovecot bug (maybe)
by Fernando Bertasso 13 May '09

13 May '09

I believe that dovecot is doing something strange, when it founds a 'corrupted' multipart and using fetch body. Look what I figured out: 1) Sent a message from squirrelmail (it wrongly drop the last \n from epilogue): ------=_20090512171902_78105 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n <--------(squirrelmail didn´t insert an additional \n). ------=_20090512171902_78105-- 2) Sent a correct message, inserting the last '\n': ------=_20090512171902_78105 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 8bit n ------=_20090512171902_78105-- 3) Compress both messages 4) Request the messages using: A004 UID FETCH 1 (FLAGS BODYSTRUCTURE) (the correct message): 127.000.000.001.00143-127.000.000.001.35604: * 1 FETCH (UID 1 FLAGS (\Seen) BODYSTRUCTURE (("text" "plain" ("charset" "iso-8859-1") NIL NIL "8bit" 7 3 NIL NIL NIL NIL)("text" "html" ("charset" "iso-8859-1") NIL NIL "8bit" *3 1*NIL NIL NIL NIL) "alternative" ("boundary" "----=_20090512171853_50085") NIL NIL NIL)) A004 OK Fetch completed. 5) Request the broken message: 127.000.000.001.00143-127.000.000.001.43679: * 2 FETCH (UID 2 FLAGS (\Seen) BODYSTRUCTURE (("text" "plain" ("charset" "iso-8859-1") NIL NIL "8bit" 7 3 NIL NIL NIL NIL)("text" "html" ("charset" "iso-8859-1") NIL NIL "8bit" *1 0*NIL NIL NIL NIL) "alternative" ("boundary" "----=_20090512171902_78105") NIL NIL NIL)) A004 OK Fetch completed. >From RFC the red numbers mean: size body, number of line for the body. This makes sense, because stripping the 'control' chars from first message, size and number of lines match. But in the second message, the line number is 0 - this does not make sense. You need to test this using telnet, because outlook and thunderbird did not follow this way, they use body.peek. What do you think? Fernando

[Dovecot] user_attrs seems not to set 'mail'.
by ian＠comtek.co.uk 12 May '09

12 May '09

Hi, I am using Dovecot 1.1.13 (from a Debian package). I was having problems using user_attrs to set 'mail' and 'home'. Initially I tried: user_attrs = uid=mail=maildir:/var/mail/virtual/users/%$/Maildir/,uid=home=/var/mail/virtual/users/%$/ This appeared to set 'home' but not 'mail'. In the debug lot I see: May 12 15:24:40 alpha dovecot: auth(default): ldap(X(a)Y,10.4.4.113): user search: base=ou=users,dc=Y scope=subtree filter=(& (mail=X@Y) (|(accountStatus=active) (accountStatus=migrate)) ) fields=uid,uid May 12 15:24:40 alpha dovecot: auth(default): ldap(X(a)Y,1.1.1.1): result: uid(home=/var/mail/virtual/users/%$/)=/var/mail/virtual/users/uid/ May 12 15:24:40 alpha dovecot: auth(default): master out: USER 30688 X@Y home=/var/mail/virtual/users/uid/ Note that 'home' seems to be set on the last line, but not 'mail'. I was hoping to see 'mail=/var/mail/virtual/users/uid/Maildir/'. Next I tried: user_attrs = =mail=maildir:~/Maildir/,uid=home=/var/mail/virtual/users/%$/ Now I see: May 12 15:31:28 alpha dovecot: auth(default): ldap(X(a)Y,1.1.1.1): user search: base=ou=users,dc=Y scope=subtree filter=(& (mail=X@Y) (|(accountStatus=active) (accountStatus=migrate)) ) fields=uid May 12 15:31:28 alpha dovecot: auth(default): ldap(X(a)Y,1.1.1.1): result: uid(home=/var/mail/virtual/users/%$/)=/var/mail/virtual/users/uid/ May 12 15:31:28 alpha dovecot: auth(default): master out: USER 30712 X@Y home=/var/mail/virtual/users/uid/ mail=maildir:~/Maildir/ Now both 'home' and 'mail' are set, which is what I want. This means the following lines are not synonymous: user_attrs = uid=mail=maildir:/var/mail/virtual/users/%$/Maildir/,uid=home=/var/mail/virtual/users/%$/ user_attrs = =mail=maildir:~/Maildir/,uid=home=/var/mail/virtual/users/%$/ Either I misunderstand the documentation for user_attrs or there is a bug. Assuming the former, can somebody please explain what I am doing wrong? Thanks, Ian

[Dovecot] Dovecot auth user lookup patch updated for maildrop 2.1.0
by mr.maX 12 May '09

12 May '09

Hi, an updated version of my patch for maildrop that extends it with the ability to perform user lookups against Dovecot's database made against the latest version of maildrop 2.1.0 can be downloaded from the following location: http://www.max.rs/ozone/maildrop-2.1.0-dovecotauth.patch.txt The patch has just been redone in order to apply cleanly without fuzz and to apply properly against one file that was changed in the latest version of maildrop. There have been no other changes compared to the initial version of the patch. For more information, take a look at my previous post to the Dovecot's mailing list at: http://www.dovecot.org/list/dovecot/2009-April/039121.html -- Best Regards, Marko Njezic - mr.maX @ MAX Interactive corp.

[Dovecot] Fail2Ban and the Dovecot log
by Lou Duchez 12 May '09

12 May '09

Hi, Is there any way to disable the "dovecot: " at the beginning of each line of the log? Fail2Ban responds poorly to it. I know there are a number of sites with "failregex" strings for Fail2Ban and Dovecot, but I've tried them all, and they don't work, at least with the latest Fail2ban and the latest Dovecot. The Fail2Ban wiki is pretty clear about why there will be a problem: "In order for a log line to match your failregex, it actually has to match in two parts: the beginning of the line has to match a timestamp pattern or regex, and the remainder of the line has to match your failregex.". So in other words, Fail2Ban expects that each line of the log will start with a timestamp. Thanks all! Dovecot rocks.

[Dovecot] Sieve & Regex
by Peregrino "Pipino" Tuc 12 May '09

12 May '09

Hi all I'm trying to create a new sieve rule. What I would like to do is catch "From" addresses that are equal to the rightpart (hostname) of a message-id. For example: Message-ID: <000d01c9d23a$941a7db0$6400a8c0@upwabm> From: "Leanne Crabtree" <upwabm(a)blomberg-co.com> I would like to catch this mail, because it has "upwabm" on the right part of the message-id and "upwabm" on the left part of the sender address. I've done this, but with no success. The error reported is: "Invalid preceding regular expression" on line with the second regex with ${1} More over I would like to add an header with the result of regex, an header like this: "X-MyHeader" "${1}" but it does not work. This is an extract of our sieve: --- require ["regex"]; if header :regex "Message-ID" "^.*(a)(.*)>$" { if header :regex "From" ".*<${1}@.*>$" { addheader "X-MyHeader" "${1}" } } ---

[Dovecot] Overwriting user Quota

Dear List, I cannot overwrite the default quota. In dovecot.conf I have plugin { quota = maildir:User quota quota = dict:user::proxy::quotadict quota_rule = *:storage=380M:messages=10000 quota_rule2 = Trash:storage=100M } To overwrite, I put in dovecot-sql.conf user_query = SELECT CONCAT('/vmail/', maildir) AS home, \ CONCAT('maildir:/vmail/', maildir) as mail, \ CONCAT('*:bytes=', quota) AS quota_rule \ FROM mailbox WHERE username = '%u' AND active = '1' Debugging dovecot: imap-login: Login: user=<x(a)y.z>, method=PLAIN, rip=a.b.c.d, lip=e.f.g.h IMAP(x(a)y.z): Loading modules from directory: /usr/local/lib/dovecot/imap IMAP(x(a)y.z): Module loaded: /usr/local/lib/dovecot/imap/lib10_quota_plugin.so IMAP(x(a)y.z): Module loaded: /usr/local/lib/dovecot/imap/lib11_imap_quota_plugin.so IMAP(x(a)y.z): Effective uid=101, gid=6, home=/vmail/x.z/x/ IMAP(x(a)y.z): Quota root: name=user backend=dict args=:proxy::quotadict IMAP(x(a)y.z): dict quota: user=x(a)y.z, uri=proxy::quotadict, noenforcing=0 IMAP(x(a)y.z): Quota rule: root=user mailbox=* bytes=398458880 messages=10000 IMAP(x(a)y.z): Quota rule: root=user mailbox=Trash bytes=104857600 messages=0 IMAP(x(a)y.z): Namespace: type=private, prefix=INBOX., sep=., inbox=yes, hidden=no, list=yes , subscriptions=yes mysql> select CONCAT('*:bytes=', quota) AS quota_rule FROM mailbox where username="x(a)y.z" and active=1; +-------------------+ | quota_rule | +-------------------+ | *:bytes=800000000 | +-------------------+ 1 row in set (0.00 sec) What is my mistake?
