[Dovecot] Errors after moving to Maildir from mbox format

[Gabe Granger]

Hi All,

Over the weekend I bit the bullet and migrated my entire office from  
server to another and converted everything from MBOX to Maildir.   
Althought it took ages and their we're a few little problems along  
the way, the migration was a complete success with no users reporting  
any problems(Mbox used to always cause file lock ups) or even  
noticing anything had changed... Which is great!:)


I'm starting to see some issues currently only with my Mail.  In the  
log files I'm getting loads of the following for at lease 20  
different emails

Jul 19 12:12:27 server imap(Some-user): Error parsing IMAP envelope:  
"Tue, 27 May 2003 16:33:07 +0100" "Re: 2U rack cases + PSU" (("Some  
User" NIL "some-user" "somedomain.foo")) (("Some User" NIL "some- 
user" "somedomain.foo")) (("Some Userr" NIL "some-user"  
"somedomain.foo")) (("Some User" NIL "some-user" "some-other- 
domain.foo")) NIL NIL "<000f01c32462$699a7130$7264a8c0 at Microtech>" NIL

I did a find in my Mail.app on my mac and discovered that although my  
client can find the message based on Subject, it fails to locate its  
mailbox/mailfolder when I select the message I get the following  
response

The message from Some User <some=user at some-other-domain.foo>  
concerning “RE: 2U rack cases + PSU” has not been downloaded from the  
server. You need to take this account online in order to download it.

The account is fully online, does or has anyone here come across this  
error? I'm guessing there is a problem within the email file itself.

I'm using

ServerSide
Debian 3.1
Sendmail 8.13
Dovecot 0.99.14-1

ClientSide
OSX 10.4
Mail.app

Any help / pointers would be great.
