Vpopmail does not "rebuild" either rcpthosts or morercpthosts from its own
database. It simply add and removes lines as necessary. So, any changes
that you make to either should stick.
I patched vpopmail.c so that it would never add to rcpthosts and therefore
only add to morercpthosts. I did t
I'd personally edit the morercpthosts file. I think rcpthosts handles 50
domains (I'm probably wrong, but that's what my memory tells me) then after
than the morercpthosts file is created and added to.
I've never had an issue manually editing either rcpthosts or morercpthosts.
Hope that helps!
