In my first message I included an example URL from an Amtrak ticket notification that it fired on.

That same message also fired on URI_HEX, URIBL_RHS_DOB, STYLE_GIBBERISH, and
MPART_ALT_DIFF which were enough to overcome the BAYES_00 and cause an FP.

Another potential change is to have URI_HEX exclude purely-numeric strings:

before:

uri URI_HEX m%^https?://[^/?]*\b(?![0-9a-f]{0,12}[a-f]{3})[0-9a-f]{6,}\b%i

after (perhaps):

uri URI_HEX 
m%^https?://[^/?]*\b(?![0-9a-f]{0,12}[a-f]{3}|[0-9]{6,}\b)[0-9a-f]{6,}\b%i
