by Kleiton L R Soares 12 Sep '06

12 Sep '06

Olá, estou com um problema que é o seguinte: Tenho uma rede com 400 pessoas, estas possuem cada uma seu e-mail. Quando recebo muitos e-mails ao mesmo tempo meu Dovecot para. Ele continua em execução porém não responde mais, então tenho que reiniciar o serviço. Alguêm pode me ajudar neste problema ? Agradeço desde já, Abraços. -- --- --------------------------- Kleiton L R Soares (21-2620-0735 | 21-9639-5829) PCS - Processos Consultoria Soluções www.pcs.com.br / kleiton(a)pcs.com.br

[Dovecot] MySQL Authentication
by Peter Fraser 12 Sep '06

12 Sep '06

Hi all I have this interesting issue. I installed dovecot on FreeBSD 6.1. The install went well. I'm trying to get it to use a mysql database that postfix is already using to authenticate. When I use this in dovecot.conf userdb mysql { args = /usr/local/etc/dovecot/dovecot-mysql.conf } passdb mysql { args = /usr/local/etc/dovecot/dovecot-mysql.conf } I get this error. auth(default): Unknown passdb driver 'mysql' (typo, or Dovecot was built without support for it? Check with dovecot --build-options) This is strange because I did compile it with mysql support. Any ideas here?

[Dovecot] TAB characters in subject header continuation/wrap lines
by Stephen Warren 12 Sep '06

12 Sep '06

I have some emails where the Subject line has been wrapped, and subsequent lines are indented with TAB characters. Specifically, here's a dump of a portion of an email: 0002020 C c : sp nl S u b j e c t : sp [ B 0002040 u i l d b o t ] sp B u i l d B o 0002060 t sp S U C C E S S nl ht ( B l d _ 0002100 g s s d k _ g s s d k _ t e s t 0002120 _ 2 0 0 6 _ 0 9 _ 1 2 _ 0 0 _ 0 0002140 1 _ 0 0 _ I n c r e m e n t a l 0002160 _ 2 ) nl X - B e e n T h e r e : Note the HT about half way through the third line. When I view this email using Thunderbird 1.5.0.5 on Windows XP, with Dovecot 1.0.rc7 running on CentOS 4.3, this TAB character shows up as a funny character in the subject line, as displayed by the Thunderbird. My question is: Should Dovecot be detecting mail header continuation lines that start with a TAB, and stripping the TAB (converting to a space)? I *think* that's what the RFCs implied when I read up on this a few months ago, but I may easily be mis-remembering. A second somewhat off-topic question: When the automated system that sends out these messages sends them to me directly, this problem does not occur, because the email titles are not wrapped. However, when I receive these emails via a mailman mailing list, mailman prepends the text "[Buildbot]" on the front of the title, thus making the title long enough to require wrapping. As such, I imagine that it's mailman that is indenting the Subject continuation line with the TAB character. Is there an issue in mailman - should mailman be indenting with e.g. a SPACE character, or is mailman's action perfectly legal? Thanks for any pointers.

[Dovecot] Using pgsql with 'cram-md5 auth' and 'hmac-md5 scheme'
by Jonathan Ballet 12 Sep '06

12 Sep '06

Hello, I want to use PostgreSQL to store my Dovecot users. I setup a very basic configuration, following word for word this page http://wiki.dovecot.org/DovecotPostgresql and it works ... almost. In fact, it works if I use PLAIN password scheme in my database. However, I would like to store them encrypted. But, if I replace the password field for my user with {HMAC-MD5}-... (the password generated by dovecotpw), it doesn't work. Here is the log, using PLAIN password scheme (all debug options activated) : =================================================== auth(default): client in: AUTH 1 CRAM-MD5 service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 auth(default): client out: CONT 1 PDU3NTgxMTE5MTcwMTYzNjguMTE1ODAxMTQzN0BkZWI2ND4= auth(default): client in: CONT 1 am9uIDJjN2RmMDVmZWZiNWU4MmE0MzFkMjM2YThhYzc2MDAx auth(default): sql(jon,127.0.0.1): query: SELECT userid as user, password FROM users WHERE userid = 'jon' auth(default): password(jon,127.0.0.1): Credentials: 3fd9989457cb3edf1fb8d31dddaf11f3f0efee3423aeb9ebf9bbe981f86a079b auth(default): client out: OK 1 user=jon auth(default): master in: REQUEST 1 23748 1 auth(default): sql(jon,127.0.0.1): SELECT home, uid, gid FROM users WHERE userid = 'jon' auth(default): master out: USER 1 jon home=/var/mail/jon/ uid=5000 gid=5000 IMAP(jon): Effective uid=5000, gid=5000 IMAP(jon): maildir: data=/var/mail/jon IMAP(jon): maildir:root=/var/mail/jon, index=/var/mail/jon, control=, inbox= imap-login: Login: user=<jon>, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, secured IMAP(jon): Disconnected: Logged out And here is the log, using HMAC-MD5 password scheme (all debug options activated too) : ===================================================== auth(default): client in: AUTH 1 CRAM-MD5 service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 auth(default): client out: CONT 1 PDI0MDc4NTQzMDc5NjU2NTIuMTE1ODAxMTkxNUBkZWI2ND4= auth(default): client in: CONT 1 am9uIDViNmE4NDI5ZjUzZTQ3YTEzZmEzNjhiOThlYjI5OTFi auth(default): sql(jon,127.0.0.1): query: SELECT userid as user, password FROM users WHERE userid = 'jon' auth(default): password(jon,127.0.0.1): Credentials: auth(default): cram-md5(jon,127.0.0.1): password mismatch auth(default): client out: FAIL 1 user=jon imap-login: Disconnected: user=<jon>, method=CRAM-MD5, rip=127.0.0.1, lip=127.0.0.1, secured The login + password used for those tests are 'jon'/'jonpwd'. In the second example, I didn't get any Credentials, whereas in the first case (PLAIN scheme), the Credentials output correspond to the 'dovecotpw' generated password (as in `dovecotpw -s HMAC-MD5 -p jonpwd`). I don't know if it's normal or not. So, I'm not sure what to do next :/ I use this kind of 'auth mechanism'/'password scheme' on another computer, with passwd-like files, and it works. So, I don't know why the same data, coming from another location, doesn't work. Any help would be greatly appreciated ! Thanks, -- Jonathan

[Dovecot] Mail does not arrive at my server.
by Wolfgang Paul Rauchholz 12 Sep '06

12 Sep '06

I run under FC5. I want to setup a mail server with postfix (already runnung) and dovecot. Once this i working I add spamassassin and clamav. I setup postfix and can send emails. When replying to these emails they do not get to my server (I checked in the Maildir directory of the user, there is no file) The server has 2 NICs. there is a firewall where I opened the port 143 (that is for IMAP?) 0 0 ACCEPT tcp -- eth1 * 0.0.0.0/0 0.0.0.0/0 state NEW tcp dpt:143 flags:0x17/0x02 the only change I made to the dovecot.conf files is: protocols = imap I did not touch the rest as in the comments of the file it says # Default values are shown after each value, it's not required to uncomment # any of the lines. Any hint on what I am doing wrong is welcomed. Thanks in advance

[Dovecot] userdb/autdb via ldaps
by Jürgen Herz 12 Sep '06

12 Sep '06

Hello, I'm using a OpenLDAP server to store mail users infos like maildir location and password. This server is running on a separate machine and I'd like to protect the connection to it by using SSL/TLS. The server is configured so that it offers ldaps and it works with other clients. But I haven't found how to configure dovecot to use ldaps. Would someone please direct me to the right place or directly help how to? Greets, Jürgen

Hi I met problem developing plug-in under FreeBSD 6.1. First I tried to use internal plugins like quota and acl but I got: IMAP(xxx): module /usr/local/lib/dovecot/imap/lib01_acl_plugin.so: dlsym(acl_plugin_init) failed: Shared object "nss_dns.so.1" not found, required by "imap" This library doesn't exist on FreeBSD 6.1 Same story when u mention any plugin in dovecot.conf… Any ideas how to fix it? -- Yours Boris

[Dovecot] Namespace with a single mailbox (for spam)
by Tom Alsberg 12 Sep '06

12 Sep '06

Hi there. Perhaps this is answered somewhere, but a short search through the mailing list and Wiki yielded nothing. We have spam filtering set up for all users, with all messages over some spam threshold going to a separate mbox. There is one directory containing the spam mboxes of all users (call it "/var/spool/spam", right now), with the spam box of a user residing in /var/spool/spam/<user>. I am trying to achieve that, in IMAP, each user will see his spam mbox as a folder named "SPAM" or something like that (possibly under some new namespace), without creating a symbolic link for each user. Is there any facility for that? Specifically, I do not want to create a single namespace pointing to the directory, since that will cause each user to have to access his spam folder under a different name (e.g. #spam.<user>), and users will also see (although not be able to read) others' spam folders.

[Dovecot] bug report, from apple.com
by Jason Fesler 11 Sep '06

11 Sep '06

Bruce includes detailed information including the imap session. Bruce works at Apple, on the Apple Mail.app product. ---------- Forwarded message ---------- From: Bruce Arthur <barthur(a)apple.com> To: dovecot(a)dovecot.org Cc: Bruce Arthur <barthur(a)apple.com> Date: Tue, 29 Aug 2006 09:04:35 -0700 Subject: Problem using Apple Mail with Dovecot Server Configuration: dovecot-1.0.rc6 Built with: ./configure --prefix=/usr/local OS: FreeBSD 4.10-STABLE i386 running on ufs Client configuration Mac OS X 10.4.7, using Apple Mail client. Issue: Apple Mail is able to connect to the server, but it is not seeing the available folder correctly. I did a little debugging and it looks like dovecot is failing to provide the separator in response to the LIST command. I did not spend anytime trying to figure out how other mail clients are getting this (my tcpdump is a little rusty these days). Here is what I see Mail sending to the server, and it's responses. 1 LOGIN applecot ******** 1 OK Logged in. 2 CAPABILITY * CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS 2 OK Capability completed. 3 LIST "" "" 3 OK List completed. The "LIST" command should be sending back the mailbox separator. The IMAP spec seems pretty clear about this (but reading RFC's is always a bit of a challenge). From the RFC: http://www.ietf.org/rfc/rfc2060.txt 6.3..8. LIST Command Arguments: reference name mailbox name with possible wildcards Responses: untagged responses: LIST Result: OK - list completed NO - list failure: can't list that reference or name BAD - command unknown or arguments invalid An empty ("" string) reference name argument indicates that the mailbox name is interpreted as by SELECT. The returned mailbox names MUST match the supplied mailbox name pattern. A non-empty reference name argument is the name of a mailbox or a level of mailbox hierarchy, and indicates a context in which the mailbox name is interpreted in an implementation-defined manner. An empty ("" string) mailbox name argument is a special request to return the hierarchy delimiter and the root name of the name given in the reference. The value returned as the root MAY be null if the reference is non-rooted or is null. In all cases, the hierarchy delimiter is returned. This permits a client to get the hierarchy delimiter even when no mailboxes by that name currently exist. Example: C: A101 LIST "" "" S: * LIST (\Noselect) "/" "" S: A101 OK LIST Completed C: A102 LIST #news.comp.mail.misc "" S: * LIST (\Noselect) "." #news. S: A102 OK LIST Completed C: A103 LIST /usr/staff/jones "" S: * LIST (\Noselect) "/" / S: A103 OK LIST Completed C: A202 LIST ~/Mail/ % S: * LIST (\Noselect) "/" ~/Mail/foo S: * LIST () "/" ~/Mail/meetings S: A202 OK LIST completed -- Bruce ------- From: Jason Fesler <jfesler(a)gigo.com> To: Bruce Arthur <barthur(a)apple.com> Cc: dovecot(a)dovecot.org Date: Tue, 29 Aug 2006 10:41:55 -0700 (PDT) Subject: Re: Problem using Apple Mail with Dovecot > Server Configuration: > dovecot-1.0.rc6 > Built with: ./configure --prefix=/usr/local > OS: FreeBSD 4.10-STABLE i386 running on ufs Thanks, Bruce. Timo et all; Bruce specifically has been looking at my instance of dovecot after a friend of his reported problems with Mail.app and my server.
