[exim] Questions/Comments about Upgrading to 4.43

Question:
    There's an updated exiscan patch, but doesn't seem to be an updated 
sa-exim patch
    Anyone using sa-exim on a 4.43?  Or has everyone migrated to exiscan 
for all this stuff?

Comment:
    4.43 is out , but not on the US mirrors.  I don't know who to tell 
about this.
