[Dovecot] 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

That's about IMAP switch. Thank you. What about any POP experience?

I have used courier-dovecot-migrate.pl. You have to use a recent version of dovecot (>=1.1) and set the uidl format in the pop3 configuration. I.e. in "protocol pop3" section, add following:
pop3_uidl_format = %08Xu%08Xv

I encounter problems when migrating the UIDL
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?

If you have advices, feel free to speak :-)

Please always send output of dovecot -n, not copy/pastes from dovecot.conf...
protocol pop3 { pop3_uidl_format = UID%u-%v }

My advice is - and no offense is intended, but - if you are going to ask for advice, it might help if you actually listened and tried the suggestions already offered:

So - you need to:
UPGRADE Dovecot (1.0.15 is OLD - latest versions available from backports), and
Adjust the pop3_uidl_format per above...
