Rob,

could you provide me a sample message (feel free to mail me directly and 
possibly as compressed attachment if you deem it sensitive) where you 
see that 1.3.0.rc1 creates massively more tokens than 1.2.5 did?


I don't see a massive change in tokens (maybe 1%) or run-time (maybe 15% 
less time needed), but it seems that one of the fixes I made may have 
undesirable side effects, namely, 
https://gitlab.com/bogofilter/bogofilter/-/commit/71bf5854db4379f48adc0920ae93fced8af87f17 
- that will want fixing because it misinterprets body tokens as headers.

Regards,
Matthias
