MacMail Issue
2012-03-31

MacMail does not seem to handle SSL connection very well. So, if you are having problem communication with email server using MacMail, you might want to turn off (uncheck) SSL connection.
This picture shows the SSL connection being checked. To get to this screen, select Mail Menu Preference --- Select Account --- Advanced Tab
This SSL connection issue is specific to MacMail software. There is no connection issue that we know about iPhone or iPad Mail software.
