I'm using
Mailjet 5.1.1
Spring Boot 2.4.3

This Spring App is Dockerized using:

FROM openjdk:8-jdk-alpine

This is how i create the mailjet Client:

ClientOptions options = ClientOptions.builder().apiKey(env.getProperty("MJ_APIKEY_PUBLIC"))
.apiSecretKey(env.getProperty("MJ_APIKEY_PRIVATE")).build();

MailjetClient client = new MailjetClient(options);

the Other code is like the exemple on the documentation here.

EDIT:

I tested from my Infra to nmap this is the result :

---

/var/www/html# nmap --script ssl-enum-ciphers -p 443 in-v3.mailjet.com
Starting Nmap 7.70 ( https://nmap.org ) at 2021-03-24 10:47 UTC
Nmap scan report for in-v3.mailjet.com (104.199.96.85)

PORT STATE SERVICE
443/tcp open https

Another Try on api.mailjet

nmap --script ssl-enum-ciphers -p 443 api.mailjet.com
Starting Nmap 7.70 ( https://nmap.org ) at 2021-03-24 11:03 UTC

No ssl-enum-ciphers: TLSv1.0 + ..... in the response.
