خطای سرور exchange بعد از نصب ssl wildcard

سلام دوستان، من بعد از نصب سرتیفیکیت ssl wildcard روی سرور exchange، در ارسال ایمیل به خارج از دامنه خودم مشکل دارم و با خطاهای زیر روبرو می شوم:

1) 

mx.google.com gave this error:
Your email has been blocked because the sender is unauthenticated. Gmail requires all senders to authenticate with either SPF or DKIM. Authentication results: DKIM = did not pass SPF [lpaco.ir] with ip: [185.171.52.147] = did not pass For instructions on setting up authentication, go to https://support.google.com/mail/answer/81126#authentication ffacd0b85a97d-37cd56b1818si1758927f8f.303 - gsmtp

2) 

mx.google.com gave this error:
[185.171.52.147] The IP address sending this message does not have a PTR record setup, or the corresponding forward DNS entry does not match the sending IP. As a policy, Gmail does not accept messages from IPs with missing PTR records.

کسی تا به حال با این مشکل مواجه شده؟
