With regard to UUCP i've also looked at the parameter swap_bangpath and
tested with this enabled. However we don't need to rewrite the bang "!" to
"@".
So I don't think this is relevant here. (I could be wrong).

you haven't explained, why do you need special characters.
(did just someone do it or you'll get fired?)

... and I am still trying to find out, why do you need to allow "!" that can
be mistook for UUCP addressing and cause unexpected behaviour on some
systems (possibly including yours)

yes, because by adding IP to mynetworks, you usually allow the sending IP
to relay mail.

the ! has still special meaning as UUCP address.

do you really need UUCP addressing?
