I investigated the thing a bit further. Postfix doesn't generally
disallow the usage of "/". It's just the local-daemon, responsible for
the local delivery of the message to a mailbox that can't handle it. 
I can perfectly relay a message containing a / in the local part of the
email address but if the delivery agent is running postfix with the
local daemon then I get the following logfile entry:

postfix/local[9934]: warning: 4D2052000F3: address with illegal
extension: srs0+uer/=bz=hilotec.net=jps
postfix/local[9934]: 4D2052000F3:
to=<srs0+uer/[email protected]>, relay=local,
delay=21, status=bounced (unknown user: "srs0+uer/=bz=hilotec.net=jps")

Wietse explains it here:

So I guess I'll have to switch to lmtp or something else if I want to
ensure the delivery of bounced forwarded messages to my own users.

Regards.
