get phplists / email cert sorted so I can add my account to gmail via TLS + FTP Login

Job ID: 31688071

Budget: $14 – $30 NZD

Just changed sever not 100% sure what I am doing but I cant get a couple of things working:

When I test email on https://pingability.com/smtptest.jsp

Tick Use Try TLS connection

REsult: SunCertPathBuilderException: unable to find valid certification path to requested target

When I try to add the email imap to gmail it wont work via TLS

Also cannot send emails via PHPlists, I think its related?

+ cannot login to FTP VIA filezilla saying wrong login.
