[16] HOW TO FIX THE SCARY CERTIFICATE MESSAGES FOR EMAIL (MACOS)

SDF uses self signed certificates which are just fine.  They
do tend to cause scary messages about the fact that they are
not signed by one of the Big Certificate authorities.  Well
that costs money and isn't necessary if you import.

To import the certificate on Macos 10.9:

Run this command on sdf, save the output into a file:

openssl s_client -showcerts -connect ol.sdf.org:587 -starttls
smtp > ol.cert
D

Copy ol.cert over to your mac then,

Applications > Utilities > Keychain Access

File > Import Items...

open the file you created above (ol.cert)

search for ol.sdf

open each ol.sdf.org certificate

open Trust

set "When using this certificate" to Always Trust
