I have a droplet (virtual private server) configured in DigitalOcean (Ubuntu 22.x) and I have set up a domain and have even obtained an SSL certificate for the domain. DigitalOcean, in one of their correspondences with me, indicated that they have completely blocked SMTP in their service. They hinted that they have provided SendGrid for mail authentication and mail service needs of their clients. In this regard, I would like to know how to set up SendGrid for mail service for my droplet or vps in DigitalOcean. Thanks
