[Dovecot] TLS / Dovecot / POP3
by John Espiro 22 Feb '09

22 Feb '09

I am using Thunderbird 2.x as my client, Dovecot on the server (POP3 not IMAP). Currently I have in my conf file: protocols = pop3s pop3 ssl_disable = no ssl_cert_file = /usr/share/ssl/certs/dovecot.pem ssl_key_file = /usr/share/ssl/private/dovecot.pem ssl_parameters_file = /var/run/dovecot/ssl-parameters.dat disable_plaintext_auth = yes login = pop3 In Thunderbird, I have the email server setup to: - Port 110 - TLS Here's my question: If I change protocols = pop3s pop3 to protocols = pop3s I can no longer connect to my mail server via Thunderbird unless I setup Thunderbird to use SSL. Am I doing something wrong? Thanks, John

[Dovecot] LDAP documentation cleanups
by Timo Sirainen 22 Feb '09

22 Feb '09

I remember some people also complained how the LDAP documentation was messy. Here's my attempt at cleaning it up: http://wiki.dovecot.org/AuthDatabase/LDAP Anything still unclear? (Other than SSL/TLS setup. Someone who knows how it really works should write something there.)

[Dovecot] Problem with v1.1.10
by Cyrus Rahman 22 Feb '09

22 Feb '09

I've been using 1.1.8 successfully but tried out 1.1.10 this morning. I have a combination of system and virtual users. The system users were unaffected by the change, but the virtual users all lost access to their mail because their home directories, as interpreted by dovecot, moved from user@domain to user@user@domain. The location of the home directory is given to dovecot for virtual users using the static db as uid=vmail gid=vmail home=/var/vmail/%u mail=maildir:~/Inboxdir Were there any changes in this area that might have caused the problem?

[Dovecot] dovecot 1.2 virtual folders question
by Robert Schetterer 22 Feb '09

22 Feb '09

Hi Timo is this possible a possible setup ? for downloading imap folders ( including inbox ) with pop3 controlled by a a dovecot-virtual file in usr/local/virtual/%d/%u/ with content something like that * -Trash -Trash/* -Sent -Sent/* -Drafts -Drafts/* all namespace private { separator = / prefix = "" location=maildir:/usr/local/virtual/%d/%u/:CONTROL=/usr/local/virtual/%d/%u/:INDEX=/usr/local/virtual/%d/%u/ inbox = yes subscriptions = yes list = yes } namespace private { prefix = virtual/ separator = / location = virtual:/usr/local/virtual/%d/%u:LAYOUT=maildir++ inbox = no } it doesnt work yet, but i am nearly sure that i havent understand http://wiki.dovecot.org/Plugins/Virtual perhaps you might bring me on the way background : i want to include a global sieve rule which sorts marked spam mails in a subfolder of inbox called Junk, so that users never can overide it and set perhaps an autoreply by an Sieve rule by incomming mail to inbox to make it possible that pop3 users may fetch sorted Spam mails outta the Junk folder too, i wanna use virtual setup folders Trash , Sent , Drafts are standart folders are standart and should be ignored with that -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] DIGEST-MD5 user/realm mismatch with Postfix
by Darren Pilgrim 22 Feb '09

22 Feb '09

This is a follow-on to the "SQL field format for digest-md5?" thread. After some additional debugging, I've found the problem is a mismatch in what Dovecot expects and Postfix uses for the user and realm. For a username "user(a)example.com" and password "sekret", Dovecot expects: username = "user" realm = "example.com" but Postfix sends the checksum of: username = "user(a)example.com" realm = "" How do I fix this?

Did you already solve this? If not, just mail the strace output to me privately and I'll take a look at it.

[Dovecot] One Dovecot serving 2 domains - possible?
by k bah 22 Feb '09

22 Feb '09

I'm talking about Dovecot 1.0.x, since 1.1.x showed some problems on some of my servers. -- Is it possible to have Dovecot on one machine serving two different domains? How can I set the mailboxes root to one domain to /dir1/ and to the other domain to /dir2/ ? I want all mailboxes from one domain to reside on a different mailbox root. I use Dovecot LDA. Is is possible to set a LDAP config to one domain and another LDAP config to the other (the auth part, I wan't users to reside on different bases on my LDAP tree, so search bases need to be different) thanks in advance = Scrublade Wipers New, Heavy Duty, wiper design to remove bugs and road slime. http://a8-asy.a8ww.net/a8-ads/adftrclick?redirectid=2b9f0c9f1afcc5e7181028e… -- Powered by Outblaze

[Dovecot] auth-worker always opens PAM session
by Miguel Di Ciurcio Filho 21 Feb '09

21 Feb '09

I'm using Dovecot 1.1.7 on CentOS 5.2. I've changed my passdb from passwd to pam, it works fine, but I've found this messages on /var/log/secure: dovecot-auth: PAM adding faulty module: /lib64/security/pam_limits.so dovecot-auth: PAM unable to dlopen(/lib64/security/pam_limits.so) dovecot-auth: PAM [error: /lib64/security/pam_limits.so: failed to map segment from shared object: Cannot allocate memory] Latter I realized that my auth_process_size was 64. Changed it to 128 and problem solved. But I suspect that dovecot should not be opening sessions, because there is no session=yes on my passdb configuration. According to the docs: args = dovecot [session=yes] [setcred=yes] [failure_show_msg=yes] [cache_key=<key>] [<service name>] session=yes makes Dovecot open and immediately close PAM session. Some PAM plugins need this to work, such as pam_mkhomedir. I checked the source code in passdb-pam.c: struct pam_passdb_module { struct passdb_module module; const char *service_name, *pam_cache_key; unsigned int pam_setcred:1; unsigned int pam_session:1; unsigned int failure_show_msg:1; }; And this: /* -session for backwards compatibility */ if (strcmp(t_args[i], "-session") == 0 || strcmp(t_args[i], "session=yes") == 0) module->pam_session = TRUE; It seams to me that the session is going to be opened anyway, since pam_session is always TRUE.

That is wath I do not understang. Can I have dict quota and mail_plugins=quota at the same time? How do I do? Thanks
