[Dovecot] Big THANKYOU to Dovecot development team
by Will Blake 21 Nov '05

21 Nov '05

Time for a positive message. As a (very) part time administrator of a small network running on an ecclectic bunch of machines I'd like to thank the dovecot team for developing such an easy to use and faultlessly functional product. Having been forced into finally replacing my UW IMAP server, I'm glad to have hit on Dovecot after struggling with mailbox transfer issues with cyrus and almost tearing my hair out. On my Fedora4 server, Dovecot was running withing a minute and reading all my folders in five further minutes, thanks Guys, Will.

[Dovecot] Shared Mailboxes, Per User SEEN flag and Mailing lists
by Reikan - Sidney Ferreira 20 Nov '05

20 Nov '05

Hi! Im making a small research about IMAP servers and it's features. As the subject suggests, I want make a shared mailbox, with per user \seen flag to work like a mailin-list works. The reason to use 1 shared folder is simple: Imagine 12k users sending 1KB messages each week, it will be 12+ MB of useless information. Many people told me that IMAP could do this, but now seem that it is a little harder then what they made it look like. Finally, some EXIM users told me that Dovecot could handle it a little better than Courier, so, Im here to try to find more information about it. Follows the mail that I received from an EXIM user.

[Dovecot] Sorting messages by date
by Stephen Allen 19 Nov '05

19 Nov '05

I've recovered a load of messages from a different mail server without it's index file (it was corrupted). I now have thousands of messages which display in Outlook Express (yes, you may puke at this), all as today's date. However when I read them in Pine, the date of each message is displayed correctly, but they're in no particular order whatsoever. There are several questions here, some of which aren't suitable for this list, but for completeness... 1. Does Dovecot store what it thinks is the date the message arrived, in it's index file? 2. Can I fake Dovecot into thinking the messages arrived on a different date by including something in the message headers, or changing the date/time stamp of each file (but I don't know how to do this)? 3. Pine correctly picks out a date from the message (although it doesn't sort by this order), and Outlook Express just displays everything as the date which it (or Dovecot) first saw the message. Does Outlook rely on Dovecot's sorting/date information or does it do it's own? Many thanks, Steve :)

[Dovecot] Can Dovecot work with an RDBMS for mail/attachment storage?
by Michael Segel 18 Nov '05

18 Nov '05

This may seem off the wall, but can dovecot be configured to support a connection to a database server and use the database server to store the e-mail message and its attachments? While you can use Postgres and MySQL for storing and authenticating users, there is a possibility to use an RDBMs to control the mail itself. Thoughts? -- Michael Segel Principal MSCC

[Dovecot] quota problem
by claper＠fmed.edu.uy 18 Nov '05

18 Nov '05

Hi, i have a problem with dovecot and quotas, when a user has over-quota he can't access the mail account to download mails and solve the quota problem. I'm using debian sarge (stable) and quota v1 (vfsold), i have installed dovecot in debian way apt-get install dovecot dovecot-common dovecot-pop3d users only can access via pop3 to their mails. This is the error i get when i try to access with an over-quota user pop3-login: Nov 18 12:35:05 Info: Login: prueba [164.73.128.2] pop3(prueba): Nov 18 12:35:05 Error: file_set_size() failed with mbox file /var/mail/prueba: Disk quota exceeded pop3(prueba): Nov 18 12:35:05 Error: mbox file /var/mail/prueba was modified while we had it read-locked, make sure all your software accessing mboxes uses the same locking methods (fcntl, flock, dotlock) pop3(prueba): Nov 18 12:35:05 Error: file_set_size() failed with mbox file /var/mail/prueba: Disk quota exceeded pop3(prueba): Nov 18 12:35:05 Error: Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2005-11-18 12:35:05] it looks like dovecot wants to write my mbox file and then gets the error with the quota, this is what i think could be helpfull from my config file protocols = pop3 pop3s mail_extra_groups = mail default_mail_env = mbox:%h/mail:INBOX=/var/mail/%u:INDEX=/var/dovecotindex/%u:CONTROL=/var/dovecotindex/control/%u mail_full_filesystem_access = yes mail_save_crlf = yes mbox_locks = dotlock thanks a lot claper ---------------------------------------------------------------- Mensaje enviado desde http://correo.fmed.edu.uy

[Dovecot] Retention Policy Feature(?)
by Ted Strzalkowski 18 Nov '05

18 Nov '05

I am currently using dovecot 0.99.14p1 on OpenBSD 3.8, mbox format, procmail+sendmail MTA. I subscribe to quite a few mailing lists and currently have procmail sorting mail into the proper mboxes. I was hoping there would be some sort of retention policy feature built in to dovecot. I want to delete mail more than X days old from X folders. I have combed the documentation, list archives, and google. Is this a feature? If so, where can I find more information on it. If this isn't a feature, is it in the works or is it left out to keep things "slim line"? Ted Strzalkowski

[Dovecot] Authentication hanging with 1.0alpha4 - mysql issue?
by brock＠theskeptik.com 18 Nov '05

18 Nov '05

Hello, Recently, I configured my server (RHEL4, 2.6.9-22.0.1.ELsmp) to run postfix 2.1.5 and dovecot 1.0 alpha4. It connects to a MySQL database (mysql 4.1.12) to verify authentication. From 30 minutes to an hour after dovecot is started, authentication and mail access works perfectly. However, after those 30 minutes to an hour, further attempts to authenticate with dovecot result in "hangs" - no temporary authentication errors are reported to the client, and no errors are logged to the dovecot log. The dovecot is still running, and responds to connections, but once the password is sent, the server fails to respond. The following line is registered in the log with each authentication attempt after the "hang": > dovecot: Nov 17 22:44:41 Info: auth-worker(default): mysql: Connected to localhost (postfix) along with an eventual disconnection notice (although no Login: line is registered): > dovecot: Nov 17 22:45:41 Info: imap-login: Disconnected: Inactivity: method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Killing and restarting dovecot immediately fixes the problem, although it reappears after 30 minutes to an hour. Following is my dovecot-sql.conf: driver = mysql connect = host=localhost dbname=postfix user=dovecot_read password=**obfuscated** default_pass_scheme = PLAIN-MD5 password_query = SELECT password FROM mailbox WHERE username = '%u' user_query = SELECT 89 AS uid, 89 AS gid FROM mailbox WHERE username = '%u' (dovecot_read has SELECT access on the postfix database, and 89 is the uid/gid of the owner of the maildirs.) I searched through this list's archives over the last two months and couldn't find anything related to this. Does anyone have any idea what the problem could be? Regards and many thanks in advance.

[Dovecot] Mailbox isn't a valid mbox file
by Cliff Hayes 16 Nov '05

16 Nov '05

Hello all, I have a new installation of Fedora 4 and Dovecot 1.4.Alpha4 A small percentage of my users are getting unable to pop mail from a client (ie: Outlook), they get continually prompted for username/password. The error they get is: Mailbox isn't a valid mbox file. When I look in the file, I don't see anything unusual. There's not much info on the Internet about this problem. The only thing I found mentioned blank lines in the file. So, I tested and found that I'm able to get mail on other accounts regardless of whether there are blank lines in between messages. Thanks, Cliff

[Dovecot] Improper listening on IMAPS
by Marian Hercek 16 Nov '05

16 Nov '05

I want Dovecot handling IMAPS. /etc/dovecot.conf: protocols = imaps imaps_listen = * ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem The problem is that Dovecot is not listening on 993 port, or there's something listening on 993, but it does not introduce itself. There's no problem if Dovecot listens on 143 (IMAP). When I telnet on 143, Dovecot introduces itself like this: $ telnet localhost 143 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. * OK dovecot ready. But when I telnet on 993: $ telnet localhost 993 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. There is not other process that would be listening on IMAPS 993 port. Dovecot was compiled with SSL support: # ldd /usr/sbin/dovecot libssl.so.0.9.7 => /usr/lib/libssl.so.0.9.7 (0x20597000) libcrypto.so.0.9.7 => /usr/lib/libcrypto.so.0.9.7 (0x205c6000) libdl.so.2 => /lib/libdl.so.2 (0x206ba000) libc.so.6 => /lib/libc.so.6 (0x206be000) /lib/ld-linux.so.2 (0x20580000)

[Dovecot] Sub-Folder Query
by Kaan Kivilcim 16 Nov '05

16 Nov '05

Hi all, I have a question in regards to folders/sub-folders with dovecot and Microsoft Outlook 2000. When creating folders if you do not append a "/" to the end of the folder name you cannot create sub-folders. Is there any solution/work around so that users do not have to append a slash on the end of the folder name? I would like to use dovecot for about a 50-user IMAP server however adding a slash to the end of folder names won't go down well with the users who are not the most computer literate people.

[Dovecot] Need to move mail
by Brent Clark 15 Nov '05

15 Nov '05

Hi all My imap server is getting to the stange where I need to start worring about the disk usage. Due to the number of users we seem to be hiring, I need to start looking at a new mail server, suppose its a blessing in disguise too. Would it be ok to just tar my current users mail (there home directory, I dont use virtual setup) and the untar it on the new mail server. Is there anything that dovecot on the new machine will complain about. Obviously I would tar everything, indexes etc. Just something I was wondering. Kind Regards Brent Clark

Yet from time to time there appear to be, how shall I say, "major" problems in the daemon that of course are no reason to whine and complain about because dovecot is OSS and everybody can do something about it. And that's where I would like to make a suggestion. From our own software projects I am used to the usage of extensive testing frameworks, like junit for java based applications. I almost completely lack knowledge about C/C++ programming, so I have no idea if something like this could be done for dovecot. For "the other end" of the mail chain I know dumbster, which is a fake SMTP server used for testing MUAs. So maybe something similar could be done for IMAP/POP3 servers? What I am thinking of is to run those tests before anything new is released. On the other hand I cannot even estimate how much work would be needed for this ...

[Dovecot] Leftover mbox behavior from uw transition
by Adam Porter 15 Nov '05

Currently running dovecot 0.99.12 on a RHEL 3 server. This system used to use UW imap with mbox mailboxes, is now using dovecot with Maildir. (Actual user shell logins are not permitted.) Performance is tremendously improved. However, we still have users that have their client imap root set to the "mail" or "mail/" directory. (Can't reach/change them all easily.) As a result, people are still (inadvertently) creating/using mbox-style mailboxes (sent mail folders most often) on the dovecot server (dovecot of course handles them without complaining) which grow and hurt server performance. Now that we've figured this out, I think we could use mb2md in a script to convert these big mbox files to Maildir. (Is there a better way?) But what would be the smart way to prevent people from creating these mbox files and still have their client work correctly with their imap root set to "mail"? We currently use: default_mail_env = maildir:~/Maildir Thanks! -Adam
