I've read a few threads on here about being able to use dovecot instead of courier on my server with cPanel. Is anything happening with this? I'm really eager to use dovecot because it seems to support the .crt/.key SSL cert format that I use with Apache, whereas I don't think courier does, meaning I can't get SSL working properly with courier.

I do see some references to dovecot stuff there but nothing comprehensive about whether and how I can use it. Care to elaborate?

check whether dovecot scripts are in your server


ls /scripts|grep dovecot

You can use those scripts to convert to dovecot.

Hello,

I've got theses scripts :

builddovecotconf
convert2dovecot
dovecot_converter

But am not sure which one(s) to use ... Maybe I should wait for the next cpanel release !

i would wait until cpanel addresses it officially

they said they were shooting to have it fully supported for 11.24, current release tree is 11.23

That is correct. cPanel 11.24 is when full support for Dovecot and NSD arrives.

Hi Kenneth,

2 quick questions if you don't mind:

1. In regards to cPanel, are the dovecot and nsd implementations designed to completely phase out courier and bind? If so, is there any approximate idea of when? Will these changes be forced, or will customers have the option of converting to either of those 2 packages indefinitely?

2. What other major changes will be taking place in 11.24 in terms of new software being introduced (either to replace existing software, or as an enhancement to cPanel servers)? I've only heard about dovecot and nsd through these forums, and seen a little about dovecot on changelog.cpanel.net.

Thanks for your input.

Conversion is a manual process. We are in the process of preparing documentation for both Dovecot and NSD that will explain the process (along with other functions specific to either service). The documentation will be available when 11.24 is released.

Support for Courier and BIND will remain. There are no plans to deprecate either. In particular, BIND offers functionality that some may want and NSD cannot offer.

2. What other major changes will be taking place in 11.24 in terms of new software being introduced (either to replace existing software, or as an enhancement to cPanel servers)? I've only heard about dovecot and nsd through these forums, and seen a little about dovecot on changelog.cpanel.net.

Thanks for your input.
Aside from the requisite bug fixes, full support for Dovecot and NSD are the only major changes for 11.24. Introducing support for two new applications is disruptive enough! :)

Thanks very much for the detailed response! My main concerns were about being blind sided with something new (to some of us anyway :) and what preparation would need to be done in advance on our end in terms of educating ourselves. I applaud vendors who don't force drastic changes on their users, and to date cPanel hasn't ever really done anything like that that I can remember (mbox -> Maildir doesn't count due to the minimal amount of time it took to get familiar with how Maildir worked on cPanel servers). Your response has made any concerns I had completely vanish about as quickly as they appeared. Thanks again.

You are welcome. Feel free to ask other questions as they arise.

There is no process for migrating from Dovecot to Courier at this time.

As mentioned, full support for Dovecot arrives with cPanel 11.24 where at that time there will be a method for migrating from Dovecot to Courier.

If you desire help in sorting out the issues you are experiencing with Dovecot, please open a support ticket at https://tickets.cpanel.net/submit/

Thank you.

I converted a very high end vps on dovecot, and now i see that dovecot-auth is taking too much cpu. Killing dovecot, reduces the load.

Is there something i missed here ? I thought dovecot reduced cpu/memory usage because of the way it functioned. I have been using dovecot for several years now on non cpanel servers with mailboxes in range of 1-5GB, and dovecot doesn't cause any load on those servers.

Please provide the ticket ID number for this issue so I can have someone take a look at this.
