Have you checked if there are any errors in Dovecot logs? There are some reasons why Dovecot might give a new UID to an existing mail. dovecot -n output might also be useful.
thanks for the reply. I just checked and the file names are correct
for the mails to be ordered chronologically, so nothing weird going on
there that would cause a prob. I can't see any errors relating to this in the logs, but my logs a
several thousand lines per day so is there any particular error
message I should be looking for? A grep -i err doesn't show anything
interesting...
Try grepping for "Warning" also. I usually put error logs to a different file. That file should stay empty (except for Dovecot stop messages).
mail_location = maildir:/var/spool/mail/%d/%u mail_nfs_index = yes mail_nfs_storage = yes
Are you using NFS? With just one server or more? What NFS server?
