As far as I can tell this is the ONLY addon that checks DNSBL's. I look forward to further developments. Would love to see some interaction with filtering/junk mail controls so that returns from DNSBL lookups can be used to determine spam or ham. In the meantime the DNSBL lookups on existing mail is certainly useful. Many thanks for the work so far.

This review is for a previous version of the add-on (1.0.2).

John, thank you for your review and feedback.

ThunderSec 1.1 introduces interaction with Junk Mail controls. There is now a button to "Mark as Junk" when a message fails DNSBL/DKIM or SPF checks. This is a manual process.

In addition to the manual process, there is also a setting in Preferences in Advanced Settings tab (disabled by default) that allows to automatically mark messages as Junk if they fail DNSBL, DKIM or SPF checks.
