Q: English terms for forwarded addresses

Hi!

Assume a forwarding recipe directs the MX server of example.com to 
forward all messages destined to alice(_at_)example(_dot_)com to bob(_at_)example(_dot_)org(_dot_) 
(Strictly speaking, it is not aliasing if the RFC2821.MailFrom is 
being changed, e.g. for SPF compliance, but rather a mailing list, 
although featuring a single fixed subscriber.) I often read the term 
"forwarded address" for alice(_at_)example(_dot_)com(_dot_) Then, what is the correct 
term for its counterpart bob(_at_)example(_dot_)org?
As I'm not a native English speaker, I'd prefer not to invent new 
terms. However, I haven't been able to spot the correct ones on the 
web. Grateful for any hint
TIA
