Not just that one, but the /8 is also too wide:

relay_from_hosts = 127.0.0.1 :\
                   ::::1 :\
                   10.1.0.0/16 :\
                   80.206.221.208/28 :
                   87.28.92.152/0 :\   ### <- THE WHOLE IPv4 space!
                   82.90.193.0/8 :\    ### <- 82.0.0.0/8!
                   80.86.144.0/22


So there are two "netblocks" there which need some serious correcting.
As they are not delegated (at LIR level or in terms of reverse DNS), and
are both part of a /16 block (in LIR terms), the netmasks need to be
*much* smaller.
