[Users] UAC behavior, specifically uac_replace_from

[Bogdan-Andrei Iancu]

Hi Keith,

I was not able to reproduce what you are describing. Do you do any other 
textops based operations on the From hdr?

the uac module adds the new URI exactly over the the old one. Actually 
it inserts two lumps: one do delete the original uri and attached to it 
another one to add the new URI.

any useful information from your side will be helpful to find the problem.

regards,
bogdan
