Rated 4 out of 5 stars

Since yesterday i have some problems with your Thunderbird extension.
For each mail i receive, sender verification shows:

Error: Could not get SPF info: DNS server occams.info:9053 refused a TCP connection

Is there any idea what has happened?

Regards
Michael

This review is for a previous version of the add-on (0.9.0.1). 

This was fixed shortly after the review was submitted. Clearly bug reports are best sent to the developer directly (unless they aren't fixed)!
