When tracking this down (72_active.cf), it looks like this:
meta SCC_BODY_URI_ONLY T_SCC_BODY_TEXT_LINE < 2 && __HAS_ANY_URI
&& !__SMIME_MESSAGE
meta T_SCC_BODY_TEXT_LINE __SCC_BODY_TEXT_LINE_FULL -
__SCC_SUBJECT_HAS_NON_SPACE
tflags T_SCC_BODY_TEXT_LINE nice
body __SCC_BODY_TEXT_LINE_FULL /^\s*\S/
tflags __SCC_BODY_TEXT_LINE_FULL multiple maxhits=3
header __SCC_SUBJECT_HAS_NON_SPACE Subject =~ /\S/
uri __HAS_ANY_URI /^\w+:\/\//
Astonishingly, __HAS_ANY_URI matches, and replacing "example.net" by
"exampleXnet" no longer leads to a match. Aside, I'm not really sure why
T_SCC_BODY_TEXT_LINE is lower than 2, given the e-mail has multiple lines (I
somehow remember that body lines are concatenated first, then body rules are
applied?).
Why does __HAS_ANY_URI match a non-URI (according to my understanding of RFC
3986), such as example.net?
