[Dovecot] How to log POP3 events
by Cliff Hayes 03 Nov '05

03 Nov '05

Hello all, Thanks for your help getting me started. I have Dovecot running now. When I troubleshoot customer email problems, I need to be able to see the number of emails they popped. In /var/log/maillog, Dovecot just tells me that they authenticated, but not what happened after they authenticated. With pop3d, I saw how many emails they popped. Can I set that in Dovecot? I checked the documentation and couldn't find anything. I also turned on the "auth_verbose = yes" and "auth_debug = yes" -- but as the name implies, I only got more authentication info. Nothing about files tranferred. Thanks, Cliff

[Dovecot] Vpopmail authentication problem
by [Mailclub] Laurent Bauer 03 Nov '05

03 Nov '05

Hello, I have a problem setting dovecot-1.0 / vpopmail authentication with virtual users. Here is my dovecot.conf (the part related to vpopmail) : passdb = vpopmail userdb = vpopmail default_mail_env = maildir:/home/domains/%d/users/%n I recompiled dovecot with "verbose" option and keep getting this error : Nov 3 11:10:58 ***** dovecot: auth(default): vpopmail(lb(a)mm.fr): unknown user (lb(a)mm.fr) whatever user/domain/password I am testing (including the correct one, of course) This is in src/auth/userdb-vpopmail.c line 35 : vpw = vauth_getpw(vpop_user, vpop_domain); According to the makefile, the binary was built with -L/home/vpopmail/lib and -I/home/vpopmail/include options ("standard" qmail/vmailmgr/vpopmail installation) so it should be ok ? I checked the permissions by setting a shell for vpopmail user, then 'su vpopmail' and read/write the password.cdb file. What could be wrong ? Has anybody got a sample config file / dovecot version working with vpopmail and virtual users, or an idea of what could be wrong in my config ? Thanks a lot. Laurent

Please keep list traffic on the list! Cliff Hayes wrote: > We are using Dovecot 0.99.14 Ok. Haven't used this for quite a while, so I don't know if I can really help you. > auth_userdb = passwd > auth_passdb = shadow Dovecot uses the homedir that's in your passwd then. But I wonder how you want to use IMAP. AFAIK, it needs a separate directory for every user anyway. At least the indexes etc. have to be stored somewhere. You should really read doc/mail-storages.txt: "mbox storage requires an IMAP root directory where to store IMAP folders and some other information..." I you can't provide a directory for every user, dovecot is probably not the software for you.

[Dovecot] Still corrupt indexes in 1A4
by Alen Salamun 02 Nov '05

02 Nov '05

Hello All! Well I still have users which almost daily get corrupt dovecot files in their IMAP folders (Maildir style) and are unable to read their mail in this particular folders. When I delete dovecot files in this folder (rm -rf dove*) user can again read all messages. This is regular Linux CentOS 4.2 with SAN storage (boot from SAN) as disks. So this is EXT3 on LVM. BUT it is VERY interesting that than happens only to two users which are connected to the server via slow links (reading via Thunderbird or Squirrelmail). It never happened (now for weeks) to other 10 users which use it localy or at home (on speedy links). It's very hard for me to exactly pinpoint the problem, since it never happens to me. But when it happened to one user again I asked him to send me screenshoot of it. I could see there that SquirrelMail said: "Warning: fgets() [function fgets]: SSL: fatal protocol error in /usr/share/squirrelmail/functions/imap_general.php on line 93." Examining this file this line is in function: --------SQUIRRELMAIL PHP SOURCE------------ /** * Custom fgets function: gets a line from the IMAP server, * no matter how big it may be. * @param stream imap_stream the stream to read from * @return string a line */ function sqimap_fgets($imap_stream) { $read = ''; $buffer = 4096; $results = ''; $offset = 0; while (strpos($results, "\r\n", $offset) === false) { if (!($read = fgets($imap_stream, $buffer))) {<- THIS IS LINE 93 /* this happens in case of an error */ /* reset $results because it's useless */ $results = false; break; } if ( $results != '' ) { $offset = strlen($results) - 1; } $results .= $read; } return $results; } } ------------------------------------------- Looks like dovecot drops connection or something. Well must be related to corrupt dovecot files in particular folder, since deleting them solves the problem. BR, Alen Salamun

[Dovecot] New Fedora/Sendmail Install Assistance
by Cliff Hayes 02 Nov '05

02 Nov '05

Hello everyone, I've narrowed down my problem, so this should be an easy one for some smart person out there. I am moving from an old sendmail/Fedora 2 box to a new sendmail/Fedora 4 box and want to try Dovecot for pop3. The problem is, I can't get it to work. I have 9000 email accounts I will be moving to the new box. I've already tried and failed once. The problem is, Dovecot wants a home directory for each one. We don't use home directories. So, when I try to pop one of the accounts that was moved over, /var/log/maillog shows: Nov 1 14:33:47 sendmail pop3(chayes): mkdir_parents(/home/chayes/mail/.imap/INBOX) failed: Permission denied Nov 1 14:33:47 sendmail pop3(chayes): Couldn't open INBOX: Internal error occured. Refer to server log for more information. [2005-11-01 14:33:47] -or- Nov 1 14:29:18 sendmail pop3(chayes): mbox: Can't create root IMAP folder /home/chayes/mail: Permission denied Nov 1 14:29:18 sendmail pop3(chayes): Failed to create storage with data: mbox:/var/spool/mail/chayes ******** But if I create folders /home/chayes/ and /home/chayes/mail with user and group set to chayes, then it works. By the way, I've tried about 20 different iterations of the default_mail_env parameter. This is the one I'm using at the moment: default_mail_env = mbox:/var/spool/mail/%u Bottom line is, if Dovecot has to have a home directory, then I guess I'll have to go back to pop3d, which doesn't. Thanks, Cliff

[Dovecot] 1.0.alpha4 released
by Timo Sirainen 02 Nov '05

02 Nov '05

The actual alpha4 release this time. With a few changes since the pre-release. The important changes again: - Default lock_method changed to flock instead of the old fcntl. Solaris users will need to set it back to fcntl. This makes sure that Dovecot's indexes aren't accidentally used with NFS. - IMAP: We might have sent extra EXPUNGE messages when output buffer got full. This could have caused various sorts of very bad behavior. This is the main reason why everyone should upgrade as soon as possible. - POP3: We sent duplicate replies for LIST command when output buffer got full. Probably caused Thunderbird's duplicate deletion bugs? (Although I thought someone checked that Dovecot's reply was correct when the bug occurred?) - pop3_uidl_format setting is now required to be explicitly set in configuration file for pop3 to work at all. I want to get rid of the old default setting which breaks Outlooks, and simply changing the default would break existing setups. - Multiple passdbs and userdbs of same type can now be added with different parameters. Some people asked about this earlier. - Authentication cache works now with other than SQL and LDAP passdbs. Some passdbs such as PAM require some additional settings to work. See example config file. - Some other fixes to authentication cache related to failure handling and non-plaintext authentication. - deny passdb wasn't working for non-plaintext authentication. New changes since alpha4 pre-release: - imap/pop3 proxy feature was broken - fixed an assert-crash in ostream-file.c that was only in the pre-release And some more changes since alpha3 that I didn't mention before: - zlib plugin updated in http://dovecot.org/patches/1.0/zlib-plugin.tar.gz to be much faster than before - Added ssl_username_from_cert setting. Not actually tested yet, does it work? - epoll was broken with 64bit systems - Added deny password databases. - Dovecot can be run from inetd again - Index breakage/crashfix related to adding new keywords

[Dovecot] Cannot build rpm with mysql support from dovecot.spec
by Erick Perez 02 Nov '05

02 Nov '05

I've been playing for hours with the dovecot.spec file to build --with-mysql. The resulting RPM builds fine but when dovecot runs it does not recognize the passdb mysql statement. I also noted that the spec file has a version of 1.0-stable and rpmbuild complains about an invalid '-' in the version. Being a newbie in rpmbuild, can someone assist me in building for CentOS 4 on i386? standard build options but --with-mysql added. I also tried to install it from sources and it does not work (at least for me). Being a RPM user now I have to clean what the source installation did and i have no clue where the 'make install' placed files. BTW I am trying to build a manual (pdf, html) with the following config and im only stuck with dovecot, the other daemons are ready. Target Server: CentOS 4 with apache, postfix, mysql, dovecot, openwebmail,clamav, clamd, php,zlib,openssh, webmin and samba. All virtual running from mysql where possible, no local users no local storage (all to the mysql db/tables). Not wanted: postgresql, courier,vpopmail,kerberos,sasl,ssl (that might be in manual v2.0 if 1.0 ever sees the light) The system does not have X (no need for fancy graphs) file used: http://www.dovecot.org/nightly/stable/dovecot-stable-20051102.tar.gz RPMs Used: All RPMs that can be located in the CentOS 4 CDs so new users (like me) can do as much as needed without downloading. Devel RPMs: All devel (mysql, pam, openssl) are installed and they are recognized at building time. Your help will be appreciated in this task. Thanks, -- ------------------------------------------- Erick Perez Linux User 376588 http://counter.li.org/ (Get counted!!!) Panama, Republic of Panama

greetings, I'm having a bit of trouble running dovecot, I receive the error; "Fatal: Can't create directory /usr/local/var/run/dovecot: No such file or directory" with an unmodified install save for disabling imap and allowing secure imap and pop3, I uncommented the base_dir in the .conf, although that did nothing. Does anybody have any suggestions? Many thanks, -Ex
