[Dovecot] Master User Features I'd like to see
by Marc Perkel 17 Aug '10

17 Aug '10

Here's what I'd like. Limited master users, where someone can be a master users for some domains but not others. I think I could do what I want with the right kinds of variable passing that doesn't yet exist. Let me see if I can explain clearly. From the example in the wiki: auth_master_user_separator = * passdb { driver = sql args = /etc/dovecot/dovecot-sql-master.conf.ext master = yes pass = yes } passdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } userdb { driver = sql args = /etc/dovecot/dovecot-sql.conf.ext } Login looks like this: # telnet localhost 143 * OK Dovecot ready. 1 login loginuser*masteruser masterpass 1 OK Logged in. I'm assuming that the masteruser and masterpass is passed to the master passdb and when doing so the variable %u is the master user. I assume that %n and %d also represent the name and domain part of the master user. What I need is to also be able to have variables for the loginuser passed to the master user query. Something like %lu, %ln, and %ld perhaps. That way with MySQL tricks I might be able to see if the master user is master for that particular login user. That way I can give domain owners or owners of multiple domains the ability to manage the email accounts within their scope of permission.

[Dovecot] cluster with dsync mirror
by Bryan Vyhmeister 17 Aug '10

17 Aug '10

I have an idea for running a pair of redundant dovecot mail servers that may be odd but it might work. I'm interested in any thoughts on the topic. Would it work to run 'dsync mirror' every minute against either mdbox or sdbox mailbox on a dedicated network connection between two (or potentially three or four) mail servers? I'm trying to avoid using a NAS/SAN or some other dedicated NFS server in a simple environment with a limited number of users. Everything else about the systems could be identical. Both could receive mail using Postfix with dovecot LDA. Thank you. Bryan

Eeeew. :) Hey, there are banks and telco places all over that are running it and they *refuse* to upgrade. I know of government sites that are still on old E450's because they have not died yet. No kidding. Some of that old Sun gear just WILL NOT bloody die.

Kernel says CPU's clock rate is 900.0 MHz. Kernel says main memory's clock rate is 150.0 MHz. Sun-4 floating-point controller version 0 found. An UltraSPARC chip is available. Use "-xtarget=ultra3cu -xcache=64/32/4:8192/512/2" code-generation option. See those compiler options ? Use them. Also put in -xO3 and -xdepend and then the compile will take a lot longer but you will be happy you waited.

It doesn't need to be portable. > In that case ... awesome :-) I'll let you know when I get packages into testing QC and then for release. However I am going to rename the package to dovecot2 in order to separate it from dovecot 1.x installs. My idea there is to allow the user to continue with the dovecot 1.x line in the event of patch updates and further releases from that tree ( like dovecot 1.2.13 ) while also maintaining the ver 2.x family. However I don't think I'll support multiple instances of dovecot ( regardless of version ) in the same Solaris zone. If the user wants that then they can do all the uid/pid hackery themselves. -- Dennis Clarke dclarke(a)opensolaris.ca <- Email related to the open source Solaris dclarke(a)blastwave.org <- Email related to open source for Solaris

Question for you: why would you use -m32 with an -xarch=sparcvis2 ?
