Unable to connect to mail store

[Jonathon -- Improov]

On a machine where I'm able to send emails out using `sendmail', can I do the same with OFBiz? Or 
does JavaMailContainer require some special SMTP setup?

I've tried entering into framework/common/config/general.properties values for properties 
"mail.smtp.relay.host", "mail.smtp.auth.user" and "mail.smtp.auth.password". I used values that I 
know should work (like the credentials of the SMTP server I am currently sending this email out 
with). Doesn't work.
