That's not what I said.  The phone mail opens the attachment but it looks 
terrible.  Sort of like what would happen if one of your MUAs knows what 
to do with reactions and another doesn't.

If you want to get rid of reactions or shunt them to a separate folder, 
the IETF-ish way to do that is SIEVE in the MDA.  But that's a separate 
issue.  Other than virus filtering my MDA doesn't look at attachments and 
lets the MUAs deal with them.

R's,
