[Dovecot] Dovecot + MySQL no auth
by Dylan Baxter 28 Jun '05

28 Jun '05

I haven't been able to login to my mail server using MySQL authentication and I believe I've found the issue. My POP log says: dovecot: Jun 07 09:58:56 Error: auth(default): sql(dylan(a)domain.com,127.0.0.1): Password query must return a field named "password" dovecot: Jun 07 09:58:56 Info: pop3-login: Disconnected [127.0.0.1] The password field in MySQL is called "passwd". Am I to understand that there is no way around this? I must rename the field to "password"? My config files all check out. I'm pretty sure I'm at a road block here. Any help would be greatly appreciated. Also, aren't there anough Dovecot users to warrant a forum and/or IRC channel? I cant seem to find either (but thank you for the mailing list!). Thanks all for any help! Dylan

[Dovecot] Restrictions on User Basis
by Net Cerebrum 28 Jun '05

28 Jun '05

Hi, I am running dovecot on Fedora Linux in our organization and use IMAP as well as POP3 protocols for mail retrieval. I want to impose the following user based restrictions: (a) I want to permit only selective users to access either POP3 or IMAP server or both. (b) The server can be accessed from LAN as well as WAN. However I want to allow only selective users to be able to access POP3 or IMAP server from the WAN side (or on the basis of IP addresses). What do I need to do to impose these restrictions ? Thanks,

[Dovecot] APPEND issue with Thunderbird
by Todd Burroughs 28 Jun '05

28 Jun '05

I'm getting a strange problem with APPEND and Thunderbird 0.8. This was working fine in the CVS version from June 8 and is not so fine as of June 20. It works fine using Pine. It appears that imap is hanging when trying to append to a folder. Right now, an imap process has the file open for about 1/2 hour. It wrote the headers out, but not the body. When Thunderbird disconnects from it, it closes the file, but does not finish writing the email. Here's the difference in the commands sent by Pine and Thunderbird from rawlogs. These are different accounts. (Thunderbird) (.in file) 2 append "Sent" (\Seen) {520+} Message-ID: <42BAC447.7050901(a)hostopia.com> (rest of headers and message follows) The .out file is empty --------------------------------------- (Pine) (.in file) 00000003 CAPABILITY 03000004 APPEND Sent {392} Date: Wed, 22 Jun 2005 19:35:42 -0400 (EDT) (rest of headers and message follows) 03000005 LOGOUT (.out file) * OK [RAWLOG TIMESTAMP] 2005-06-22 19:36:20 * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE LOGIN-REFERRALS 00000003 OK Capability completed. + OK 03000004 OK Append completed. * BYE Logging out 03000005 OK Logout completed. ----------------------------------------- Todd

Hi, Is there any planned support for FAM http://oss.sgi.com/projects/fam/ in dovecot? One of my favourite features of Courier IMAP server is that it alerts my email client through IMAP when email has arrived. Regards, Mick

[Dovecot] pop3 retr error
by Marten Lehmann 28 Jun '05

28 Jun '05

Hello, I'm getting the following error while Mozilla Mail is downloading >4000 emails: The RETR command did not succeed. Error retrieving message. Mail server xxx responded: Message is deleted. So what's the error? Can't I retrieve a message, that has been marked as deleted before? If the Mesage-ID wouldn't exist, the error message would be different. I don't know what Mozilla Mail is doing and on which message id it is failing. Also, there's no output in the logfiles. Any ideas? Regards Marten

[Dovecot] quetion about duplicate messages
by Michiel van Es 28 Jun '05

28 Jun '05

Hi, we recently switched from Imap-Uw to Dovecot as a pop3 server. I was wondering why people who have the flag 'Leave messages on server' in their email client (Outlook, Outlook Expres) that they receive duplicates of their stored mail? Is it because Dovecot doesn't know that the messages has already been popped by Imap Uw or is the email client which thinks there are new messages on the server and if so..how can I avoid this behaviour? Thanks in advance for any help. -- Kind Regards, Michiel

by neo anderson 23 Jun '05

23 Jun '05

hi, i'm newbie to dovecot. lately i install postfix on a server for providing mail service. however, i encounter a problem in receiving mail, i.e., to get mail download to the remote client. (i'm able to send mail through mozilla client, but can't get the sent mail download to the client). what reasons may cause such problem? check several points that i suppose it may have problem, yet can't figure out where the problem may be resulted from. for instance, ========== telnet beg telnet target-server-ip 143 ... * OK dovecot ready. telnet target-server-ip 25 ... 220 host-name.domain.com ESMTP Postfix (ehlo localhost) <---------- hidden command i enter 250-host-name.domain.com 250-PIPELINING 250-SIZE 20971520 250-VRFY 250-ETRN 250-AUTH LOGIN GSSAPI DIGEST-MD5 CRAM-MD5 PLAIN 250-AUTH=LOGIN GSSAPI DIGEST-MD5 CRAM-MD5 PLAIN 250 8BITMIME (quit) <---------- hidden command i enter 221 Bye telnet target-server-ip 110 .... +OK dovecot ready ========== telnet end btw, i'm able to read and write mail through mail program in the target server; simply can't get the mail downloaded to the other client with mozilla mail client (out look also doesn't work). mozilla mail client is version 1.7 . target server using centos 4.0. postfix 2.1.5 dovecot-0.99.11-2.EL4.1 i appreciate any help, sincerely. ___________________________________________________________ How much free photo storage do you get?

[Dovecot] miugrating mail to new server
by Gabe Granger 22 Jun '05

22 Jun '05

Hi All, I've just a new server to help with migration of our email, the old email server is using mbox and the new is using Maildir. I've managed to some user mail migrated fine. The new server is only a temp server as I have too many users to migrate easily in one go(Also I want to nuke the current mailserver, remove SuSE and install Debian on it). So what i'm doing it moving users one by one to temp server and converting to Maildir. My question is. I notice that all email files in maildir format end with .<host> when I go to migrate everything to back over to the original server is this going to cause me problem? Ie will the original server now have to be named the same as the temp server so that the maildir format files end with the same .<host> or does that not matter? Any help, advise would be great. Gabe

22 Jun '05

Hi, I am running Dovecot (dovecot-0.99.11-2.EL4.1 on centos 4) and we are switching from newer machines. I copied all usernames from /etc/passwd,/etc/group and /etc/shadow to the new machine. I do not want that every user has it's own /home/$user directory.. When I test my dovecot installation with a telnet 'servername' 110 user test pass test I get this error: ################################################################################ Jun 20 13:22:47 mx01 pop3(aaptest): mbox: Can't create root IMAP folder /home/aaptest/mail: Permission denied Jun 20 13:22:47 mx01 pop3(aaptest): MAIL environment missing and autodetection failed (home /home/aaptest) Jun 20 13:22:47 mx01 dovecot: child 3393 (pop3) returned error 89 ############################################################################## So I changed the MAIL environment to /var/spool/mail (using Sendmail and mbox) Now I get this error: ###############################################################################3 Jun 20 13:27:37 mx01 pop3-login: Login: aaptest [::ffff:10.101.3.37] Jun 20 13:27:37 mx01 pop3(aaptest): open(/var/spool/mail//inbox, O_CREAT) failed: Permission denied Jun 20 13:27:37 mx01 pop3(aaptest): mkdir_parents(/var/spool/mail//.imap/INBOX) failed: Permission denied ################################################################################# Wht is Dovecot trying to AUTOcreate IMAP folders?

It's not currently # possible to specify multiple addresses.

[Dovecot] test73 not compiling with iconv?
by Sean Porter 22 Jun '05

22 Jun '05

I've recently upgraded from test53 to test73 from a source compile on FreeBSD 5.3, and am getting some [BADCHARSET] errors in 73 that I wasn't getting in 53 (specifically with Squirrelmail). When I run one of Squirrelmail's built-in filters, I get the following error: ERROR: Could not complete request. Query: SEARCH CHARSET ISO-8859-1 UNSEEN Subject {14} *****SPAM***** Reason Given: [BADCHARSET] Unknown charset Googling around, I found the admonition on the wiki about chrooted environments: http://wiki.dovecot.fi/moin.cgi/QuestionsAndAnswers#head- e146cada4e103a4a93a736998c64f23b1a8cd312 so I disabled all chroot directives in my config and ran as root, just to see if that was the error. No luck. When running configure with "./configure --with-mysql --with- storages=maildir --with-ssl=openssl", I noticed that I got this error regarding iconv: checking for iconv... no, consider installing GNU libiconv Oddly enough, I do have libiconv-1.9.2 installed in /usr/local: /usr/local/lib/libiconv.a /usr/local/lib/libiconv.so@ -> libiconv.so.3 /usr/local/lib/libiconv.so.3 /usr/local/include/iconv.h and an iconv -l shows support for the charset in question. I tried adding the prefix directive to configure: ./configure --with-mysql --with-storages=maildir --with-ssl=openssl -- with-libiconv-prefix=/usr/local and got the same message. I presume that 53 picked up iconv headers and libraries from LD_LIBRARY_PATH, and now 73 isn't getting it even set explicitly -- I see some ChangeLog entries for iconv files in dovecot source in May, but nothing more. How can I verify that dovecot compiled with libiconv support? Anyone else see the same thing? Thanks, Sean

[Dovecot] GSSAPI support status
by Fredrik Tolf 20 Jun '05

20 Jun '05

Hi list! I'm wondering, what is the current status of GSSAPI (krb5) support in Dovecot? I know from googling that there used to be a patch for it around a year ago, but I haven't seen a trace of that patch ever since, and GSSAPI doesn't even seem to be mentioned in the Dovecot source tree (at least not according to "grep -irl"). Is GSSAPI planned at all, as it stands? If not, is there a way for me to get my hands on the original patch, so that I can fix it up for the current version of Dovecot? I'm eagerly waiting for the day that I can switch from UW-IMAP to Dovecot, but I don't want to until I can get GSSAPI authentication. Thanks for reading! Fredrik Tolf

[Dovecot] "Angle" address with empty "display name"
by Chris Wakelin 20 Jun '05

20 Jun '05

Some clients are sending from addresses like <someone(a)somewhere.org> i.e. without a "friendly" name. It seems to me from RFC2822 that you should either have "Display Name <someone(a)somewhere.org>" or just "someone(a)somewhere.org" (both without the quotes). Dovecot, not unreasonably, treats "<someone(a)somewhere.org>" as having an empty Display Name, but this seems to confuse at least one client - our webmail ;) - which then displays "?" for the "from" address. The patch below tries to make dovecot treat empty display name as non-existent display name (so that the IMAP "ENVELOPE" command responds with "NIL" instead of "" in the relevant places).

[Dovecot] MySQL user_query ignored
by Helmut Zeilinger 20 Jun '05

20 Jun '05

Hi all, i installed Dovecot 0.99.14. Everything works fine except that the mysql setup directive "user_query" seems to be ignored - however the password_query works. Instead the default user query in db-mysql.c always takes effect. Might this be a bug or is something worng wit my setup below? (To keep on working i changed the default query in db-mysql.c..) Helmut dovecot-mysql.conf: db_host = localhost #db_port = 3306 db_unix_socket = /var/lib/mysql/mysql.sock db = mail db_user = mail db_passwd = db_client_flags = 0 default_pass_scheme = PLAIN password_query = SELECT password FROM users WHERE login = '%n' and domain='%d' user_query = SELECT '/var/mail/%d/%n' as home, 506 as uid, 100 as gid FROM users WHERE login = '%n' and domain='%d'

[Dovecot] dovecot.index.cache 1/3rd of INBOX size
by Chris Wakelin 17 Jun '05

17 Jun '05

I've noticed that my dovecot.index.cache file has got very large (24MB, which is more than 1/3 of my INBOX size). I've tried deleting (well, renaming) the dovecot.index.* files, and re-opening my INBOX, and the new dovecot.index.cache is only 90KB so far. I'm using dovecot-1.0-stable and mbox format. My mail_cache_fields and mail_never_cache_fields are set to the default. Looking back in the list archives, I found a message from Timo that suggested the cache entries are created for each message when the indexes are created, rather than when each message is accessed, so it ought not to grow? What happens when a message is deleted? I "strings/grep" ed through the dovecot.index.cache file and it looks like it's not caching any headers it shouldn't (like Received, X-Spam-XYZ etc.), but they seem to occur multiple times for each message. None of my other dovecot testers seem to have huge cache files (yet!). Anybody else seen this?

[Dovecot] Compressed maildir
by Curtis Maloney 17 Jun '05

17 Jun '05

Greetings, I noticed a while back someone posted a patch/plugin that allowed Dovecot to use compressed mbox files. I'm now wondering how far that would put us from having compressed maildir? I have a server with more CPU than disk space, and while I can buy more HDD space, my backup solution doesn't make that practical. It seems to me that when looking for a message file, if it ends in .gz unpack it, and otherwise everything acts as normal. Worst case, this is one strcat() and a stat() slower to find. Newly delivered messages could remain unpacked, and a cron job could come by whenever to compress old/large/un-looked-at-for-months messages. So, new and frequently referenced messages would be as fast as ever, and older messages would be slower. I would love to dive in an do this myself, but 1- my time is very very limited, working two jobs, and 2- I'm not running 1.0 yet, as it apparently still doesn't support my Thunderbird users tagging their messages (am I wrong? please tell me I'm wrong... I want to upgrade! :) -- Curtis Maloney cmaloney(a)cardgate.net

[Dovecot] SSHA with LDAP?
by Ben Beuchler 16 Jun '05

16 Jun '05

Poking around in the code for dovecot-stable seems to indicate that support has been added for the {SSHA} password scheme. This is not reflected in dovecot-ldap.conf. Is the SSHA code actually functional? Thanks! -Ben

[Dovecot] small dovecot problem
by Cor Bosman 16 Jun '05

16 Jun '05

Hi all, just noticed a small problem in test70. If you have an mail in your maildir 'new' directory, and use another method to delete that email (for instance pop it through another pop server), dovecot will continue to report that email as being on the server. So if you had 1 email, delete it through pop, dovecot will continue to say that 1 email is on the server, even if you disconnect/reconnect. If that same email is in the 'cur' dir (so its been read), this doesnt happen and dovecot will report 0 emails. Cor
