[Dovecot] [Q] IMAP update message header?
by Roderick A. Anderson 08 May '08

08 May '08

More about IMAP, less about Dovecot. This is more an IMAP question than specifically about Dovecot. Sorry to ask here but I've been researching, reading and lurking with no answer so far. What I'm doing is running reports as a user from a remote system to provide a list of messages (Sender/From, Subject, Date, size) in a specific folder(?). In one case it isn't even a Dovecot based server so I only have access as a client. (Though I use Dovecot on several other systems and will need this capability for them.) When a message in the folder has been reported I'd like to add a X-Header-??? indicating that the message has been reported so the next time through it isn't reported again. (After the message is X days old it is deleted.) These reports are run using Perl and I've tried most every CPAN module available but haven't figured out how to change/add a header then save the message back. So far I haven't been able to determine if this is even possible by reading the RFCs. Is there a method as a client from a remote system to make changes to a message then save it back? What is the IMAP verb, command, etc. to do this? Or if there are Perl programmers on the list a brief description (or code) for doing this? TIA (and sorry for the off topic posting), Rod --

This will allow you to test things and see if it works better. The changes will revert to the system pre-defines when you re-boot or restart. IIRC, there is a master setting (unchangeable without recompiling OS X) that will not allow you to go over 65536, but I may be mistaken about that. For a permanent change, add the following lines to the /etc/sysctl.conf file: or the /etc/sysctl-macosxserver.conf file for Mac OS X Server You may have to create the file, especially if you are the only user. (Make sure that only root has access to this file!!!!!!) kern.maxfiles=65536 # System-wide limit kern.maxfilesperproc=32768 # Per-process limit This Is ONLY For OS X 10.3 or later. For earlier versions you need to use /etc/rc which was so long ago that I do not recall all of the commands (sorry). HTH, Jerry

[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!
