TLS Email certificate Has Expired

So I am working on a script on my server and that has came up with some errors - and in searching the problem seems to be with a certificate error. The script is access the email server tls. I get the error stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed in Running ssl test I get an error saying SSLVersion in use: TLSv1_2 Cipher in use: ECDHE-RSA-AES128-GCM-SHA256 EXPIRED: Certificate 1 of 1 in chain: Cert VALIDATION ERROR(S): self signed certificate; certificate has expired So email is encrypted but the recipient domain is not verified Cert Hostname DOES NOT VERIFY (hostname.com != host.hostname.com) So email is encrypted but the host is not verified Ideas on how to fix this. I have gone into the Manage SSL Hosts and everything is fine, even went into Manage Service SSL certificates and looks fine, I have Exim and Dovecot current. I must be missing something, been searching for a while now on this and finally came to ask. thanks
