User original : Samir3577!o-mmc-ca808ffbe@ (ident with 15 chars)
By typing this command on mIRC 7.58:
//echo -a $address(Samir3577,0),1,64)
He returns:
ident with 10 chars ???!!
The identity remains blocked at 10 characters but I configured UnrealIRCd 5.0.1 and Anope 2 up to "20 characters" but on mIRC it stops at 10.
