I seem to just love looking like a fool on this ML; and after reading RFC
(2)822 I see that strictly speaking SA is doing the right thing ("Unfolding is
accomplished by simply removing any CRLF that is immediately followed by
WSP.").
IRL, however, I see unfolding done in a s/(\n\s*(?=\s\S)/\ /g-ish way (take a
look at A.5. in 2822); and I'm getting e-mails where the subject's been folded
with added whitespace (basically indenting the second line the length of the
name of the header + 2).
AFAIK these added whitespaces are not shown in most mailreaders.
Based on a blurry "I'm pretty sure"-ish feeling I can't check due to me
messing with all the headers before they're saved, I think that the
SUBJ_HAS_SPACES rule would benefit from ignoring "indenting" WSP
("/(?<=\S)(?:\s{4,}|\t)/"?).
Would it be possible to set up an environment where you can test changed/new
rules against a set number of spam and non-spam, preferably the same ones used
for the current GA-scores?
