Is there a reason that headers are left with leading spaces?
I’ve noticed that I have to write rules as:
Subject =~ /^ Great [Jj]ob [Oo]pportunity/
because of the leading space… Given the text of RFC-2822:
NO-WS-CTL = %d1-8 / ; US-ASCII control characters
%d11 / ; that do not include the
%d12 / ; carriage return, line feed,
%d14-31 / ; and white space characters
%d127
text = %d1-9 / ; Characters excluding CR and LF
%d11 /
%d12 /
%d14-127 /
obs-text
FWS = ([*WSP CRLF] 1*WSP) / ; Folding white space
obs-FWS
obs-FWS = 1*WSP *(CRLF 1*WSP)
utext = NO-WS-CTL / ; Non white space controls
%d33-126 / ; The rest of US-ASCII
obs-utext
unstructured = *([FWS] utext) [FWS]
subject = "Subject:" unstructured CRLF
Might we consider dropping the first instance of “FWS” preceding the first
instance of “utext” in “unstructured”?
