I installed the mailer extension on a Radiant installation (0.6.3 running on Nginx + Mongrel), and as soon as I submit a form I get a 500 error. This is a snippet from production log, can anyone figure out what’s the problem?

Giovanni, I had a similar issue with error 500 being thrown. Check to make sure you don’t have any “funky” things in your config part. My Subject: line contained brackets ([KangarooBox] Feedback) that really hosed it up. I removed those brackets and everything was fine. Later… Richard
