What's keeping huawei.com from an A

Fix or remove the AAAA record for huawei.com
Something published an IPv6 address but nothing answers on it, so IPv6 visitors wait for a timeout first. Either make the server listen on IPv6 (and allow ports 443/80 through its firewall), or delete the AAAA record until it does.
Mail servers without IPv6
mx7.huawei.com, mx5.huawei.com, mx8.his.huawei.com, mx9.his.huawei.com have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
