Hi,

I got a:

<aviad.krawczyk@huawei.com>: host huawei.com[103.218.216.136] said: 550
5.1.1 Error: invalid recipients is found from 80.12.242.127

However, MAINTAINERS has:
   HUAWEI ETHERNET DRIVER
   M:	Aviad Krawczyk <aviad.krawczyk@huawei.com>
   L:	netdev@vger.kernel.org
   S:	Supported
   F:	Documentation/networking/hinic.txt
   F:	drivers/net/ethernet/huawei/hinic/

I don't know how this should be fixed (neither if it should be...), so if s.o. knows, please do.

Best regards,
Christophe Jaillet
