WC32 does support SSL emails, like gmail, however, WC8 does not have code space to support SSL email. Many ISPs provide non-SSL email service for its network range, for example, if your ISP is COX, its plain SMTP port is 25 at smtp.cox.net without authentication. If your hosting company is bluehost or some other hosting company, they also support non-SSL email REQURIRE authentication, you will need to contact their support to find out port number and server name.
If anyone knows free public plain smtp server, please post here.
Socketlabs.com allows to have a free account sending 500 plain smtp email a month. It does require authentication, its port is 25, 2525, and 587. Some ISP blocks port 25 going outside their network, in that case, you will need to try port 2525 and 587.
