E-mail forwarding don't work

[joximu]

ok, I think you need to find the error by deactivating som extensions (amavis eg) temporarly...

you have enough infos to check the relevant parts...

ah - maybe "receive_override_options = no_address_mappings"

this prevents the alias thing....

but only should be set before the content filtering - afterwards this should not be set.

see
http://www.postfix.org/FILTER_README.html

I think this may be the problem....

how does the master.cf look like?
