Not checked yet. Stuff probably breaks with whitespace in local parts. > Can this be checked by Lintian ? Lintian uses Email::Address::XS. That seems to allow Unicode (allowed by RFC 6532, but not by RFC 822), but also doesn't flag obsolete syntax (whitespace). It accepts the address `käse <"kä se"@example.com>`: perl -mEmail::Address::XS -E ' my $x = Email::Address::XS->parse(q{käse <"kä se"@example.com>}); say $x->is_valid(); ' So it is more generous than Policy either way.
