[Dovecot] transitional weirdnesses
by Eric S. Johansson 20 Aug '03

20 Aug '03

1) not reproducible but when it occurred, its stuck: in the early transition to dovecot I would notice occasionally that messages would come up, I would delete them and then something would hang causing a major delay in the (Mozilla) e-mail client's response. When the system responded, I would notice that occasionally there would be an off by one offset between the index of messages and the message displayed. This error would persist until I killed off the index and the dovecot process. 2) very reproducible: after fetching messages from my inbox, there will be a long (30 sec.) delay. Dovecot demon is clearly busy doing something. I do have a large set of filter rules (approximately 150) sorting messages into different boxes. Is this a reason to switch to maildir? 3) just ended up with a message that displayed the entire header. Will look into this more but it's very strange. ---eric

[Dovecot] Squirrelmail and Dovecot folder namespace
by Warren Togami 19 Aug '03

19 Aug '03

I am currently using Squirrelmail and Dovecot with this setting: default_mail_env = mbox:%h/mail/:INBOX=%h/mail/INBOX It works well, however folder subscriptions in Squirrelmail annoyingly end up with "./" prefixes because Squirrelmail refuses to work without overriding the folder namespace. All of my other IMAP clients work fine without setting that option. Squirrelmail's default setting is this: $default_folder_prefix = './mail'; This setting breaks Squirrelmail: $default_folder_prefix = ''; This setting becomes default if you attempt to blank that user's preference: $default_folder_prefix = './'; The end result of this is duplicate entries in .subscriptions, one with "./" prefix and one without. Most IMAP clients handle this by showing all the folders again in a folder named ".", or Mozilla displays all folders twice. =( When I asked one of the squirrelmail developers, he said that this might be a dovecot specific problem. Any ideas? Warren Togami warren(a)togami.com

[Dovecot] Questions
by Alejandro Martinez 19 Aug '03

19 Aug '03

Hi, I'm still figthing with passwd-file, virtual users and permissions. I have created the directory /var/spool/virtual/test and inside I've done a "maildirmake Maildir". I have a couple of questions : I use the same passwd-file for auth_userdb and as auth_passdb. 1) What program can I use to create the userdb file ? What I do now is to use the htpasswd program and then I complete by hand the rest of the fields (uid:group:GECOS:home:shell) htpasswd userdb test password: xxx again: xxx And then vi userdb test@test.com:ssasZXc00P1H6:502:102::/var/spool/virtual/test/:/bin/false <--by hand. I think that if I want to offer virtual mail with imap is very tedious to complete user by user. (If this second question does not fall in this list, then don't answer it) 2) I know that postfix delivers in Maildir format, and when the user is a virtual user, I do the next Modify the virtual file ---> test(a)test.com test.test.com Modify the aliases file--> test.test.com: /var/spool/virtual/test/Maildir postmap hash:virtual postaliases hash:aliases postfix reload but when I do a "echo testing | sendmail test(a)test.com " I receive an error Aug 18 15:32:44 slk90 postfix/pickup[12208]: 95C3717D5C: uid=0 from=<root> Aug 18 15:32:44 slk90 postfix/cleanup[12252]: 95C3717D5C: message-id=<20030818183244.95C3717D5C(a)slk90.equital.lx> Aug 18 15:32:44 slk90 postfix/qmgr[12209]: 95C3717D5C: from=<root(a)slk90.equital.lx>, size=291, nrcpt=1 (queue active) Aug 18 15:32:44 slk90 postfix/local[12254]: 95C3717D5C: to=<test.prueba.com(a)slk90.equital.lx>, orig_to=<test(a)prueba.com>, relay=local, delay=0, status=bounced (cannot append message to destination file /var/spool/virtual/test/Maildir: cannot open file: Permission denied) I'm confused about permissions. I set the /var/spool/virtual to dovecot.postfix and the permissions are drwxrwx--- Thanks a lot. --- Outgoing mail is certified Virus Free.

[Dovecot] CVS note

Another large update for header caching which breaks your old indexes. I think it's working pretty nicely now. Only some smaller tweaking left to do with caching in general.

[Dovecot] more transitional joys
by Eric S. Johansson 17 Aug '03

17 Aug '03

well, now that I have moved to dovecot, I'm not getting any spam... in fact, I'm not getting e-mail at all. default_mail_env =mbox:~/IMap2/:INBOX=/var/spool/mail/%u when I first tried to access my inbox, I was told I had permission problems: Aug 14 17:47:22 harvee imap(esj): open(/var/spool/mail/esj.lock) failed: Permission denied Aug 14 17:47:22 harvee imap(esj): file_lock_dotlock() failed with mbox file /var/spool/mail/esj: Permission denied so I changed permissions on /var/spool/mail to 777 as a temporary work around. no luck. It tells me that I have no e-mail in my inbox... fat chance [root@harvee mail]# ls -l /var/spool/mail/esj -rw------- 1 esj mail 167772 Aug 14 18:05 /var/spool/mail/esj what simply obvious thing I am I missing now? ---eric

[Dovecot] login w/ IMAP & LDAP
by Bob Hall 16 Aug '03

16 Aug '03

I'm getting imap-login: Internal login failure: bob whenever I try to check mail. I'm new to mail server setup, new to IMAP, and I don't know a heck of a lot about authentication schemes. I've set up Dovecot as an IMAP server on FreeBSD 4.8. I've got OpenLDAP running on the same system. Users will access mail via Eudora on Windows and Macs, so that's how I'm testing. If I try to test Dovecot using IMAP commands via telnet, Dovecot tells me LOGIN BAD Error in IMAP command received by server. I also can't telnet via localhost; I have to specify the host name, so I'm connecting via the host's external interface. I have no problem connecting to localhost on ports not used by Dovecot. So I have two questions: 1) How do I correct my configuration to make login successful? 2) How can I test Dovecot without using an MUA? If I have to use an MUA, I can't distinguish between errors in the MUA and errors in the IMAP server. Thanks for any help with these two. Configuration follows. Eudora: Server configuration: IMAP IMAP Mailbox Location Prefix: /var/mail/bob/Mail Authentication Style: passwords dovecot.conf ---------------- protocols = imap imaps imap_listen = *:143 login_user = dovecot default_mail_env = mbox:/var/mail/%u/Mail auth_userdb = ldap /usr/local/etc/dovecot-ldap.conf auth_passdb = ldap /usr/local/etc/dovecot-ldap.conf auth_user = dovecot dovecot-ldap.conf ------------------- hosts = localhost dn = cn=dovecot,dc=domain,dc=tld dnpass = ********** ldap_version = 3 base = ou=accounts,dc=domain,dc=tld deref = never scope = subtree user_attrs = uid user_filter = (&(objectClass=inetOrgPerson)(uid=%u)) pass_attrs = uid,userPassword pass_filter = (&(objectClass=inetOrgPerson)(uid=%u)) default_pass_scheme = PLAIN slapd.conf ----------------- password-hash {CLEARTEXT} If I change this last to CRYPT (comment out the dovecot-ldap default_pass_scheme and change the slapd.conf password-hash to {CRYPT} and re-enter the password into LDAP), I get the same error. I have no problem accessing the LDAP data from the command line. If I comment out the dovecot-ldap.conf user_filter and pass_filter, I get dovecot-auth: ldap(bob): unknown user I interpret as meaning that the user_filter and pass_filter are necessary. Bob Hall

Hello, i don't like asking stupid questions in mailinglist, 'cause i guess you got something better to do than answer it. But well this is an exception, because i didn't find anything on google. Here comes my problem: I'm using a NetBSD 1.6.0 System with the latest dovecot build. i want to start dovecot imapd by: root@balin:[/etc]$ ./rc.d/dovecot start Starting dovecot. Fatal: Error in configuration file /usr/pkg/etc/dovecot.conf line 88: Missing value This is my error ;) This is the line 88 in my conf file. maildir:/home/%u/mail the maildir was created by 'makemaildir mail' and exists: root@balin:[/home/tobi]$ ls -all total 18 drwxr-xr-x 4 tobi users 512 Aug 15 09:11 . drwxr-xr-x 3 root wheel 512 Aug 13 01:18 .. drwx------ 5 tobi users 512 Aug 14 12:47 mail there it is. in default option of the maildir line dovecot starts without problems but i really want to have my mails in /home/%u/mail and not in /var/mail/%1u/%u/mail So could somebody please put some light on it? Thank you, Tobi

[Dovecot] joys of transition.
by Eric S. Johansson 15 Aug '03

Red Hat 8.0 stock dovecot 99.10 for a variety of reasons, I decided to cut over to dovecot this morning. I extracted all of my mailboxes from mbx purgatory back to mbox purgatory, set up dovecot and proceed to get authentication failures. (am using simple password based authentication either direct or through pam) I turned authentication verbosity on and got: Aug 14 11:51:38 harvee dovecot: Dovecot starting up Aug 14 11:51:46 harvee dovecot-auth: PAM: pam_authenticate(esj) failed: Authentication failure Aug 14 11:51:49 harvee dovecot-auth: PAM: pam_authenticate(esj) failed: Authentication failure Aug 14 11:51:52 harvee imap-login: Aborted login [192.168.0.10] not very informative. I already know that I can't login. So I fire up ethereal and capture the following transaction: * OK dovecot ready. 1 authenticate login 1 NO Unsupported authentication mechanism. 2 login "esj" "no peeking" 2 NO Authentication failed. 3 authenticate login 3 NO Unsupported authentication mechanism. 4 login "esj" "no peeking" 4 NO Authentication failed. 5 logout * BYE Logging out 5 OK Logout completed. hmm no unsupported authentication mechanism. So that means all authentication methods works right? ;-) looking a little further into the configuration, I see instructions to change auth_methods to add plain in front of digest-md5 (or is it digest_md5, both forms are present in the configuration file). No luck. Doing so gives me the following error message: Fatal: Error in configuration file /usr/local/etc/dovecot.conf line 430: Unknown setting: methods so, I'm not sure what to look for. It's probably something simple but googling didn't reveal anything pertinent although it turned up something amusing[1]and dovecot does apply. Suggestions or clues would be welcome. FYI, you probably could use a little bit more detail in the install instructions. For example instructing user to create a dovecot user and group name would be useful as would be a startup/shutdown script for init.d. I also find the SSL configuration lacking. On the other hand, I have enough scar tissue from certificates and mini-CA setups to hate them till the end of time. If I get them working better, I'll document and send it to the list. ---eric [1]http://www.oblomovka.com/eldritch/iag/ob1-5.htm
