*Correction:* "So it seems postfix can accept special characters, I'm just not sure how to allow this for every *recipient*"
It allows special characters in senders local part of a email address It allows special characters in the recipients local part of a email address when the senders ip is in mynetworks. (I think postfix sees it as a internal/local mail) It does not allow special character for recipients when the senders ip is not in mynetworks.
