Lotus/Domino 6 mask

Hi All,

I'm trying to crack some Lotus notes 6 hashes (-m 8700) but I'm not quite sure what mask I should be using. Is it the same as Domino 8? (-m 9100):
-a 3 ha?l?l?l?l?l

I've tried this and I haven't had any luck. Maybe some other issue?

They're discussing the topic here but I couldn't quite figure it out for myself:
https://hashcat.net/forum/thread-3550.html

Since that thread is super old I figured I'd make a new post about it

Thanks for the help!
