[Dovecot] Re-downloading mails after migrate server
Hi all,
first of all, I must say that I am pretty new to mailing lists, so please, if I do something wrong, just tell me.
Now, my problem. I'm migrating a mail service from a temporal to a definitive server. Both servers have the same versions (Postfix, Dovecot -1.0.7, POP3 & IMAP services-, MySQL) and it all works perfectly. The only problem is with the users that store their mail on the server; on the testing, when I check if there is new mail, I download the mail stored on the new server once more. After that, it works correctly (no more unwanted downloads), but I need to avoid that first download.
I have been investigating before writing to the list. I have checked that UIDL are the same on both servers, and the configuration is exactly the same except for the name of the server; I have seen in few places that it may be the cause for downloading thdovecote mail again, so I changed the name of the new server to the old's one, but it happened again.
I know that lots of servers are migrated every day, and never heard about those problems, so I suppose it must be a solution for this, or maybe a better way to configure the servers.
If you wanna take a look at the configuration of both servers, I have pasted them on here --> http://pastebin.ca/2051228
Please, let me now if you need any more information.
Thanks in advance

Happen to us as well. Seemed to be specific to certain email clients though. Thunderbird and Eudora did not download all the emails, Outlook did.
It appeared to also occur with users that POP3 using multiple clients (Outlook and smart phone for instance) as well as those that had Outlook set to "Leave a copy on server for x days".

I think a good try is update the new server to latest dovecot version. I migrate about 1.5M mailboxes from dovecot 1.0.X to Dovecot 2.0.X and no problems (and we have a lot of users with the "leave copy on server" option checked).

Hi all... again.
I have uploaded the new server to dovecot 2.0.12, and still having the same issue. I have even tried changing the hostname, and still the same. I have checked the site http://wiki2.dovecot.org/Migration at the "POP3 migration" section, and I can't see the problem. The UIDLs between hosts are still the same, and I am lost at what is making me download the mails saved on the server.
Any more ideas? They'd be highly appreciated. Thanks in advance

If you both old and new servers are connected to with the same hostname and the same username, and they give exactly the same output to UIDL and LIST commands, there's something wrong.
Thanks Timo, Yes, I suppose there must be something else wrong, but I am not sure what it could be.
