mail location change generates various errors

7 Nov 2014


      I have a sendmail/dovecot imap/pop3 system that has been running with
the following mail_location:
mail_location =
mbox:/var/empty:INBOX=/var/spool/mail/%u:INDEX=/var/indexes/%u
In order to reduce errors and simplify operation I removed imap and am
now only responding to pop3.  I'd like to also simplify the
mail_location to get rid of index errors since I don't need indexes:
mail_location = mbox:/var/spool/mail:INBOX=/var/spool/mail/%n
But when I applied the new mail_location I began to get the following
five errors:
Nov  6 23:17:24 sendmail dovecot: pop3(chayes): Warning: UIDVALIDITY

What do I need to do to transition to the new mail_location without the
errors?
Thanks in advance.
