[Dovecot] XUIDL Migration problems
Hello All,
I am new to Dovecot and the Dovecot mailing list.
I am trying to migrate an existing Exim + qpopper - mbox (pop3 only) installation over to Exim + Dovecot using mdir (pop3 and imap) And am running into problems with preserving the XUIDL headers.
I am running Dovecot 2.0.14
I have used the mb2md.pl script : http://dovecot.org/tools/mb2md.pl from this page http://wiki2.dovecot.org/Migration/MailFormat to migrate and import the mboxes And have the following pop3 uidl settings in my configuration .
pop3_reuse_xuidl = yes pop3_save_uidl = yes protocols = imap pop3 service imap-login { inet_listener imaps { port = 993 ssl = yes } } service pop3-login { inet_listener pop3 { port = 110 } inet_listener pop3s { port = 995 ssl = yes } protocol pop3 { pop3_reuse_xuidl = yes pop3_save_uidl = yes pop3_uidl_format = %08Xu%08Xv }
The problem specifically is that when I test the migration and import a mailbox, I am able to connect via IMAP using Thunderbird and Outlook 2007 and the Read / Unread status is preserved. However when I connect via POP3 the Read/Unread status is not preserved.
I am probably missing something simple, but have been unable to find anything that seems relevant on the Dovecot wiki or searching the mailing lists. Any suggestions would be appreciated.

Are you sure the UIDLs are the problem? Did you connect to old and new POP3 server and compare their UIDL lists?
However when I connect via POP3 the Read/Unread status is not preserved.
Another possibility would be simply that if you changed the hostname in the client config, it might have thought that it's a completely different server.
Hi Timo,
Thanks for the quick reply.

No not 100% sure that the UIDLs are the issue; but running into dead ends with what I have tried. I will compare the UIDL lists from the old / new server and report back.

The new server is a completely different host and currently had a different IP, but it will end up with the same name and IP as the existing host when we cut over. At this time I have manually adjusted my lost hosts file to point towards the new host for testing.
Would this be a problem even though the IMAP appears to be working were as the POP is not.??
I'll report back on the UIDLs
Regards, Steven
