dovecot - May 2010 - looking for feedbacks on courier to dovecot

Manao ahoana, Hello, Bonjour,

We currently run courier POP .
We would like to switch to Dovecot.

I encounter problems when migrating the UIDL because we have big
Maildirs and POP re-downlading the data is not possible for most of the
users.

I tried the http://www.dovecot.org/tools/courier-dovecot-migrate.pl
script but I still have the re-downloading event.

What are your stories and advices about courier-to-dovecot move?

Misaotra, Thanks, Merci.

Hi,

When moving my users from courier to dovecot I used the imapsync tool, which I 
then made a script for.

Some info on imapsync http://freshmeat.net/projects/imapsync/

This worked great, and as it preserves flags users did not have to re-download 
mail. You might want to tune some of the parameters like wheter to subscribe 
to folders or not.

No, I only had maybe 100 accounts to move, so I don't know how well it
stacks
up with moving large amounts between servers.

Cheers,

Arne

My current proble is UIDL, just for POP:

On courier:               On Dovecot:           
UIDL                      UIDL                  
[...]                     [...]                 
252 UID436864-1244045323  252 UID4452-1272985490
253 UID436865-1244045323  253 UID4453-1272985490
254 UID436866-1244045323  254 UID4454-1272985490
255 UID436867-1244045323  255 UID4455-1272985490
256 UID436868-1244045323  256 UID4456-1272985490
257 UID436869-1244045323  257 UID4457-1272985490
258 UID436870-1244045323  258 UID4458-1272985490
259 UID436871-1244045323  259 UID4459-1272985490
260 UID436872-1244045323  260 UID4460-1272985490
261 UID436873-1244045323  261 UID4461-1272985490

They dont match at all (from 1 to 261)...
All is leny based, so:
- courier-pop    0.60   on one side
- dovecot-pop3d  1.0.15 on the other side

I used then the
http://www.dovecot.org/tools/courier-dovecot-migrate-1.0.pl (old one)
convert script.

What are your suggestions?
