Hi, Is there any plans to use the Linux inotify, which is a major improvement over dnotify ? (Linux mechanism for communicating filesystem events to user space) Regards, -- Nico Écrivez dans l'ivresse, mais relisez-vous à jeun. -+- André Gide (1869-1951) -+-

This is still # fine, except Outlook doesn't connect back so you don't see if new mail # arrives. # outlook-pop3-no-nuls: # Outlook and Outlook Express hang if mails contain NUL characters. # This setting replaces them with 0x80 character. #client_workarounds = # Dovecot can notify client of new mail in selected mailbox soon after it's # received.

[Dovecot] Limit Number of Postgres Database Connections

I have dovecot running with postgres backend. I am exceeding my maximum database connections (currently 40) with dovecot 0.99.10.9 and postfix and was wondering if dovecot has a parameter to limit the total number of database connections that it will create. Dan

Hi guys, Just tested yesterday's stable build, when including SQL into the build I am getting an error on like 86 of passdb-sql.c (passdb_result = PASSDB_RESULT_OK;) It rightly says passdb_result is undeclared. Commenting out this line fixes it and build appears to work fine after that. Regards Andrew -- Andrew Hutchings Linux Guru Netserve Consultants Ltd. http://www.domaincity.co.uk/

[Dovecot] Problems with Dovecot and self-signed cert
by Seth Bokelman 22 Feb '05

22 Feb '05

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've recently set up a Red Hat Enterprise Linux 4 WS server, and decided to try using Dovecot as my IMAP server, as I was impressed with the dedication to security that seems to be the core development goal. I'm really happy with it, but I can't get it to work with a self-signed cert. Normally, on a RHEL system, you just go into /user/share/ssl/certs/ and type: make whatever.pem Then you fill out the various address fields, and you've got a cert. However, when I rename/delete the existing dovecot.pem and generate a new one using this method, Dovecot won't start and I'm unable to connect to the box. The cert that it's currently using is called "localhost.localdomain", and while that works, mail clients gripe every time about the domain name not matching the certificate. I've looked through the RHEL documentation, and it appears I'm doing everything correct. Anyone have any suggestions? - -- Seth H.

Yes indeed, after trying all the various options on the mail client, i discovered that it was this "Compact" switch.

[Dovecot] uw-imap and gnu-pop3d to dovecot transition/replacement
by Jani Karlsson 22 Feb '05

Hi I am trying directly to replace old uw-imap + GNU pop3d with Dovecot. Problems I am having with new (1.0-stable 22.02.2005) are: - How to get SSL working with new config? imaps_listen doesn't exist anymore. cannot add protocol imaps for some reason. - need to get Dovecot run on another port the test-phase, ie 144 for imap, 994 for IMAPs - need to use .mailboxlist (modified the source already, this maybe works - due SSL problem not tested?) - no symlinks etc can't be done (simply too many mailboxes) so how to make dovecot read IMAP-directories from user's homedir.. Anything else I should know before trying this transition? All help truely appreciated. Jani. (Mailbox count is high which why transition to faster postclient-server software is necessary - or adding few more dual CPU-servers.. and doing anything but editing config/such by hand is not a option.)
