I have issues using postfix on my digitalocean droplet (they block the smtp port). Is it possible to setup using SendGrid for the email verification and notifications ?

      you can define it as environment variables in https://github.com/LemmyNet/lemmy-ansible/blob/main/templates/docker-compose.yml i.e mine contains these lines:

        postfix:
    image: mwader/postfix-relay
    environment:
      - POSTFIX_myhostname=group.lt
      - POSTFIX_inet_protocols=ipv4
      - POSTFIX_smtp_sasl_auth_enable=yes
      - POSTFIX_smtp_sasl_password_maps=static:smtp_username:smtp_password
      - POSTFIX_smtp_tls_security_level=may
      - POSTFIX_smtp_sasl_security_options=noanonymous
      - POSTFIX_relayhost=sendgridsmtpserver:serverport
      - OPENDKIM_DOMAINS=group.lt
    restart: "always"

        thanks! got it working now. In SendGrip generated an api key, at - POSTFIX_smtp_sasl_password_maps=static:smtp_username:smtp_password filled in apikey:[theapikey] and relayhost=smtp.sendgrid.net:587

        also add a verified From address in SendGrid, which is added in your lemmy.hjson email.smtp_from_address

          Thank you for sharing!

          I’m trying to figure this out and I’m stuck at creating the file to save the API key. Where did you put the file in the lemmy-ansible setup?

          Now you need to specify your credentials (use apikey as username and an API Key as password) in the separate file /etc/postfix/sasl_passwd (you’ll likely need to create it):

            after installing with ansible, change the docker-compose.yml file on you server passing the api in the ENV variable:

            the postfix section now looks like this

              postfix:
    image: mwader/postfix-relay
    environment:
      - POSTFIX_myhostname=[yourdomain.tld]
      - POSTFIX_inet_protocols=ipv4
      - POSTFIX_smtp_sasl_auth_enable=yes
      - POSTFIX_smtp_sasl_password_maps=static:apikey:[api-key]
      - POSTFIX_smtp_tls_security_level=may
      - POSTFIX_smtp_sasl_security_options=noanonymous
      - POSTFIX_relayhost=smtp.sendgrid.net:587
      - OPENDKIM_DOMAINS=[yourdomain.tld]
    restart: "always"
