Thanks for your email, Patrick.   Has this behavior changed in IMP4?   
Is there a need to sanity check the To line for trailing dots, commas, 
mismatched <>s, etc? 

(I'm willing to create  a patched by extending what you did, but would 
like one of the development team to comment on the issue - I wouldn't 
want to patch the code if I'm just missing a configuration issue or if 
another workaround/solution is available).

Thanks again Patrick.
