Firewall Requirements for SendGrid Connector using Tibco Scribe Online

If you use the SendGrid Connector and you have a restrictive firewall, here are the endpoints/ports that need to be opened on the on-premise agent to allow email to be sent using SendGrid:

 

Open ports 80 and 443 to:

  • *.sendgrid.com
  • smtp.sendgrid.net

 

Open ports 25, 465, 587, 2525 to:

  • smtp.sendgrid.net

 

Allow the traffic to api.sendgrid.com and smtp.sendgrid.net regardless of the destination IP address.

 

For Palo Alto Firewalls: Allow application identification for SendGrid. Add a custom URL category with these two domains - *.sendgrid.com and smtp.sendgrid.net
