▪ Google Internet Authority G2
▪ GeoTrust Global CA
▪ Equifax Secure Certificate Authority
▪
Each certificate's content is located between the line of "BEGIN
CERTIFICATE" and the line of "END CERTIFICATE".
▪
The topmost certificate is the server certificate.
4. The section titled "Server certificate" indicates that the issuer (CA) Google
Internet Authority G2 issues the server certificate.
5. As the server has the server certificate and two intermediate certificates,
we conclude that this server sends a partial certificate chain to the
receiver.
6. Check whether the issuer "Equifax Secure Certificate Authority" is the root
CA.
▪
If yes, you only need to upload the root certificate self-signed by
Equifax Secure Certificate Authority to PX3TS.
▪
If not, you need to find all missing issuer certificates, including the root
certificate, and upload them to PX3TS.
Step 2 -- Find and download the content of missing issuer certificate(s):
1. View the name of the issuer (CA) at the bottom. In this example, this issuer
is 'Equifax Secure Certificate Authority'.
2. Use the issuer's name 'Equifax Secure Certificate Authority' to search for its
certificate on the Internet, and then download or copy the content from an
authentic source, which is usually its official website.
Important: To prevent the downloaded certificate from being modified or
manipulated, you must secure the download with TLS via a trusted
certificate.
3. As it is found the Equifax Secure Certificate Authority's certificate is self
signed by 'Equifax Secure Certificate Authority', which indicates it is the
root CA, there are no more missing certificates to search for.
Step 3 -- Upload the missing certificate(s) to PX3TS:
1. Paste the root certificate's content into a plain text file that will be
uploaded to PX3TS.
▪
Content copying must include the lines of "BEGIN CERTIFICATE" and
"END CERTIFICATE".
2. Save that file as a .pem, .crt or .cer file. In this example, it is named as
"my-root.pem."
3. Upload the file "my-root.pem" to PX3TS for using the GMAIL SMTP service.
