Makes sense.  I'm not a dovecot expert, but in terms of RHEL, have you
checkd that the yum update didn't change file permissions, or enable
selinux or do something like that?

Can you see the mail using none IMAP based tools?  What do the dovecot
and postfix logs show?  And what about squirrelmail?  Check all your
logs for permissions issues.  

What else got updated when you did the yum update?

doveadm log errors

might give you some hints.
