 * Hi guys,
 * Short question here regarding your **communications security**.
 * Is SSL (port 465) limited to a Mailjet premium version?
 * I’m testing the free version and selecting port 465 SSL returns an error:
    `Your
   settings have been saved, but your port and SSL settings were changed to ensure
   delivery`
 * Thank you,
    Andrei

 * Hello,
 * SSL is not limited in any way. All free and paid accounts can use it.
    Please
   check with your hosting provider if they are blocking the port.
 * Kind regards,
    Martin

 * Hy Martin,
 * After further testing I see that the only port I can select & save is port 80.
   
   So this is an issue related to my hosting provider?
 * Thank you,
    Andrei

 * Hi, usually this is the case. Hosting providers block most ports for security
   reasons. Sometimes they agree to unblock ports on user request, so it is worth
   to check with their support.

 * Hi Martin,
 * Due to “_security reasons_” my Namecheap hosting provider has all ports closed
   by default. Upon my request they opened port 587.
 * Thank you,
    Andrei
