[exim] Partial matching for *.test@domain.tld

Hello,

is it possible to do matching for "*.test@???" ?

I would like all mails to "*.ob@???" go to one mailbox,
and all mails to "*.af@???" to another (so I can't use
"catch all").

I try partial matching, but Exim said :
"partial" is not permitted for lookup type "lsearch@"

But maybe I made an error too...


Thanks,
Olivier
