[Dovecot] Urgent - Inconsistent Inboxes

[Jakob Curdes]

Hi,

An urgent problem that I have :

runninng dc 0.99.14 w mbox on local ext3 , nothing special, no nfs, 
nothing.
For this machine we have a backup server rsyncing everything over. Now 
the main server went down and we started DC on the backup machine some 
day ago. Everything went well, besides one problem : people complained 
about missing mails that they had seen beforehand. When looking in the 
inbox, they were all there. After recreating the imap account (outlook 
express) or deleting the cache file (thunderbird .msf files) everything 
was well. But you can't really recreate all accounts after switching to 
the backup machine every time.... today we went back to the main server 
and in advance I deleted all .imap.index files hoping that they might 
have been the eventual cause of the problem, but no, same thing happens 
again. It now seems to me that this is a pure client issue, but 
nevertheless two questions :

a) who knows a way to tell the client (OE or TB in this case) to 
disregard all local information and get everything fresh from the server ?

b) Can this behavior be influenced from the server side? I know I'm 
behind with 0.99.14 but up to now there was no problem and "never change 
a running system". If upgrading could help, I would do it immediately.

Any hints welcome, especially fast ones as tomorrow morning I have to 
get the clients running.

Yours,
Jakob Curdes
