How do I allow traffic through my firewall to my mail server?
Techmail, firewalls, whitelisting
Instead of whitelisting by IP on your firewall:
- Write a function that allows whitelist by domain. Many routers may allow whitelisting by domain with advanced configuration options. Work with your router/firewall vendor to write the function. For mail servers only the *.rightnowtech.com domain needs to be white listed.
However, if your policies do not allow a wildcard you may whitelist only the servers which pull mail. Use "utilXX.rightnowtech.com" where XX is pod name or "utilXX.cx.usd.oraclecloud.com" for restricted pods. If you do not know your pod name please Ask Technical Support.
- Use SMTP forwarding. A simple and permanent solution to whitelisting problems would be to SMTP forward mail from your pop accounts into pop accounts on our servers. Then techmail would not have to pull from your mail servers and traverse your network.
Server IP addresses on our infrastructure may change without notice. Although a customer may be informed in advance of a pod migration, they will not be given advance notice of a disaster recovery event or mail server change. Therefore our environmental configuration guide suggests several domains to be whitelisted.
