Strip carriage returns (^M) when filtering emails

Browse source 
Presumably some email servers will transform newlines into carriage
return new lines to better support windows users. I can't prove this but
that's the best explanation I have for my hosted email provider
(fastmail).

Without this patch, I was seeing annoying `^M`s at the end of every
filtered line.
