Hi, I have installed the hotfix-7496 for resolving IE 11 UI issues in our application(PRPC v6.2 SP2). After the hotfixes installation, we got issues in sending emails. We raised a SR and from support team we got another hotfix 6029. We installed this hotfix in Development and QA servers. Now the email issue is resolved. But in the description of the hotfix 6029, it was mentioned like, we should not install this hotfix in Production server as it will lower the security levels. We raised this concren to Support team and they replied back saying "Please configure corresponding application server's trust store to work correctly such that STARTTLS-enabled Email Infrastructure. This requires one populating the application server's trust store to accept the SMTP server's security certificate." In tomcat application server, we can able to register the certificate. Can anyone tell us how to link this with Pega application's Key store and hot to resolve this email issue ?
