How to relay outgoing emails through something like MailJet?

[cyl3x]

Is it possible to route all outgoing emails through MailJet? If not, how would i redirect the traffic to a smtp relay?

MailJet offers an SMTP relay service: https://www.mailjet.com/feature/smtp-relay/

To use it for all outbound traffic, replace target.remote in maddy.conf with target.smtp and configure it appropriately.
Example:

target.smtp outbound_delivery {
  targets tcp://in-v3.mailjet.com:25
  require_tls 
  auth plain USERNAME PASSWORD
}
