  The index files are on NFS (home directory), ~/Mail/INBOX points to

 Is Dovecot running on more than one computer? That error message looks
 exactly like what would happen if Dovecot saw two different INBOXes but
 the same index files were tried to be used with both of them.

Our IMAP(s)/POP3(s) server is a single host so this should not happen.
 
 http://wiki.dovecot.org/MboxProblems anyway lists all the possible
 reasons for that problem.

I've now put the whole Mail directory of the user on a local filesystem
to see if that makes a difference.

 Is there a problem if an incoming message already contains an X-UID
 header? Might it be worthwhile to remove this header when mails are
 being delivered (e.g. with procmail)?

Yes, it's a good idea and it might fix this problem, but I don't know
any specific bugs that would cause invalid X-UID header to be used.

http://wiki.dovecot.org/MboxProblems has more information about this.
