[Dovecot] How do I increase the fd limit on OS X?
by Rob Frohne 08 May '08

08 May '08

Hi All, I just upgraded to the new 1.1rc5 from 1.0 that I had been using and it advised me to increase the file descriptor limit. I'm not sure how to do this. There is a command built into tcsh that allows me to do this called limit, but sudo limit 4224 doesn't work, and usually dovecot is started from the rc.local file if I recall right, and I'm not sure how to set this up from there. Any advice. Thanks, Rob -- Rob Frohne <rob.frohne(a)wallawalla.edu> Walla Walla University

Not true! simple way: Just change the default config TB create your account from with the settings you need. You can find the file under your program dir i.e. C:\Programme\Mozilla Thunderbird\defaults\pref Compare the defaults to your working set of setting and change them accordingly. You can activate TLS or CRAM-MD5 and so an. You can also predefine LDAP servers etc. more elaborated way: Mozilla Mission Contol: -> http://developer.mozilla.org/en/docs/MCD,_Mission_Control_Desktop_AKA_AutoC… Hope it helps! Hans

[Dovecot] thunderbird sane config (OT)
by rosenfield.albert＠gmail.com 08 May '08

08 May '08

Does anyone have any experience putting together a sane config for Thunderbird in an automated fashion? Automated meaning "simple to distribute to users". -- (Background: I'm currently experiencing that Thunderbird does not work against Postfix/Dovecot because the wizard interface for setting up an account does not accept TLS-only servers. Users just sit there with a broken Thunderbird, not knowing what to do :-/.) (PS: Also, giving everybody a GMail-like threaded interface per default would be cool.) (PPS: If anything good comes up, I plan to put this in fx the Dovecot wiki.)

[Dovecot] Clarification wanted on mail_access_groups vs. mail_privileged_group
by Mark Sapiro 07 May '08

07 May '08

I have just upgraded to dovecot 1.0.13. All the documentation I can find in the example .conf file and the NEWS and ChangeLog files seems to say that the mail_privileged_group = mail setting is all I should need to make dovecot use group mail to create dotlock files. My understanding from what I read is that mail_privileged_group is used to set the group used while creating dotlock files in (in my case) /var/spool/mail, and mail_access_groups is used to set the group used to actually access the mailbox. In my case, /var/spool/mail is group 'mail and group writable/searchable drwxrwxr-x 2 root mail 4096 May 7 08:35 /var/spool/mail and the individual mailboxes are owned by the respective users. So it seems that I would need "mail_privileged_group = mail" do be able to create dotlock files in /var/spool/mail, and that I would not need any mail_access_groups as the users can access their own mailboxes. But this doesn't work. With "mail_privileged_group = mail" and mail_access_groups unset, I get May 6 12:48:54 sbh16 dovecot: POP3(xxx): file_lock_dotlock() failed with mbox file /var/spool/mail/xxx: Permission denied Yet with "mail_access_groups = mail" and mail_privileged_group unset, it works with no problem. Is my understanding wrong? Is the documentation wrong? Is the implementation wrong? Or is there just something wierd in my case (possibly pop3_lock_session = yes)? # dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf protocols: pop3 pop3s ssl_cert_file: /etc/postfix/grizz-cert.pem ssl_key_file: /etc/postfix/grizz-key.pem login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/pop3-login mail_access_groups: mail mail_location: /var/spool/mail/%u mbox_write_locks: fcntl dotlock mail_executable: /usr/local/libexec/dovecot/pop3 mail_plugin_dir: /usr/local/lib/dovecot/pop3 pop3_lock_session: yes pop3_uidl_format: %08Xu%08Xv auth default: mechanisms: plain apop login worker_max_count: 5 passdb: driver: passwd-file args: /usr/local/etc/dovecot.passwd passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.

[Dovecot] dovecot pop3 proxy with AUTH PLAIN
by Luis Barrueco 07 May '08

07 May '08

Hi, I tried as hard as I could, but I couldn't get this working. So here I come begging for help :) I need to configure dovecot to proxy some users' incoming pop3 connections to another server running the Zimbra Collaboration Suite, trying to log into zimbra via a master password. The problem I found is that zimbra only allows me to log in as a master user with the "AUTH PLAIN" mechanism, but it seems that dovecot uses the "USER.... PASS" authentication when proxying. Am I missing something? Has anyone ever tried to do the proxy+master password to zimbra? I'll post my configurations down here. I really appreciate your help- ----------------------------- dovecot version: 1.0.13 ----------------------------- "dovecot -n" output: # 1.0.13: /usr/local/etc/dovecot.conf protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_privileged_group: mail mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv auth default: passdb: driver: pam passdb: driver: sql args: /etc/dovecot/dovecot-sql.conf userdb: driver: passwd ----------------------------- /usr/local/etc/dovecot-sql.conf: driver = mysql connect = host=172.16.0.252 dbname=dovecot user=usuario_dovecot password=miclave password_query = SELECT password, 'secret_zimbra' as pass, host, destuser, 'Y' AS proxy FROM proxy WHERE user = '%u' ----------------------------- sudo tcpdump -w output_tcpdump -i eth0 dst host 172.16.0.20 and dst port 110: .........USER mnunez master ......... .........PASS secret_zimbra ----------------------------- I hope this information was helpful!

[Dovecot] FETCH for mailbox INBOX UID 5003 got too little data: 5369 vs 38919

This happened a while back, I was running 1.1rc3 up until today so I have no idea if it would have an effect. Sorry if its something that has been fixed. The error below was repeated many many times, I deleted the index so the user would stop getting disconnected (although I didn't hear any complaints).
