[Dovecot] uw-imap and gnu-pop3d to dovecot transition/replacement
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.)

I'm assuming you're using a test1.0-xx version?

From my understanding of the 1.0 config files, you should be able to put a "listen" line inside the "protocol imap {" section. Also, a "ssl_listen" option could go in there.
Someone else on the list want to double check me on this?

There is a section of the documentation Wiki covering migration from UW-IMAP. There should be no reason for symlinks - dovecot can be told where to find mail boxes, if you haven't set/got the mail env in the user db.

In future, it often helps to remember to mention your OS version and Dovecot version when asking for help. In the case of this query, there were config file format changes between 0.99 and 1.0... but with more involved bugs, it can matter a great deal more.
Other than that, most people seem to find Dovecot a whole lot faster than UW-IMAP, though I have no basis for comparison - Dovecot is the first IMAP server I've installed, and I've seen no reason to wander...

Yeah, would be nice to hear that too, I've tried this and result was that it it listens Unencrypted (non-SSL) IMAP on both ports. I've also tried to make protocol imaps {} but it complains about invalid protocol.

Yeah, these instructions I've followed so far, but problems are with making Dovecot to listen on different ports (and SSL on those alternate ports).

Yes, funny.. I thought I also putted these details in but I guess I missed them afterall.

Yeah, well I am running corporate mailserver so I don't do anything without testing and comparing it first. Dovecot has been tested on another similiar server for (alot faster then uw-imap)speed, now all thats pending is getting it tested on production use (in different TCP port) - testing machine doesn't have all those troublesome mailboxes in it.. and finally just removing old software and switching dovecot's ports so that it runs on production use.
