---------------------------------------------------
2008-03-31

If your default cert expires and you are tired of clicking continue everytime
you open mail.app on your OSX client machine.

1.  In case you screw up, make some backups of these files first!
	a. /usr/share/doc/dovecot-0.99.11/dovecot-openssl.cnf
	b. /usr/share/ssl/private/dovecot.pem
	c. /usr/share/ssl/certs/dovecot.pem
	d. /usr/share/doc/dovecot-0.99.11/mkcert.sh

2.  vi /usr/share/doc/dovecot-0.99.11/mkcert.sh
	set the filenames imapd.pem to dovecot.pem and save the change

3.  vi /usr/share/doc/dovecot-0.99.11/dovecot-openssl.cnf
	set the C, ST, L, O, OU, CN and emailAddress to your desired settings

4.  chmod +x /usr/share/doc/dovecot-0.99.11/mkcert.sh

5.  run mkcert.sh
	make sure you have a dovecot.pem in the private and certs dirs

6.  service dovecot stop

7.  service dovecot start

8.  Make a copy of the dovecot.pem from the certs directory in a place where
	your OSX client can access it.  Double-click the file and it will
	import into your Keychain.  Choose X509Anchor.

9.  launch Mail.app and you should go directly to your email, no need to click
	continue on your expired cert.
