Hi, I am using Appian 7.3 and trying to send email using SendEmailAct

Hi,

I am using Appian 7.3 and trying to send email using SendEmailActivity. Although i have used the same configuration that i used for Appian 7.2 But this time its giving error. I have tried to configure two mailboxes( One external to the appian server and one internal to the appian server -- James). But for the server its giving me an error which is attached for your reference.
Please see if anyone could provide any solution....
