Problem with echolot 2.1

I just started seeing problems with echolot pings from other pingers to my remailer.

Mixmaster (on Linux) is reporting these error messages now (when it didn't before Echolot 
2.1 was released):

Notice: Blocked header line: From: Echolot Pinger <estragon@remailer.frell.eu.org> matches 
/^From:/

The pinger changes, so I know it's not just Frell. Mixmaster said this about my own pinger 
when I upgraded to 2.1.

Do I have a misconfiguration somewhere or is there a bug in Echolot 2.1?

Thanks.
