I got this problem just before New Year. I checked with my domain host but according to them NTC already blocked port 25 for sending emails. They gave me a new smtp server for sending emails but this is now on SSL. My problem is that I got an error message everytime I send email. The error - "Unable to establish a secure connection to xxxx.xxxx.com (smtp server) because the correct root certificate is not installed. If you continue, the information you view and send will be encrypted, but will not be secure" So, anybody who can help me resolve this error. Thanks in advance.
