Thanks for your post. There seem to be two issues with UnrealIRCD's banlist changes here:
1) The ban list is meant to consist of non-case-sensitive addresses. So this will break case-insensitive handling throughout mIRC of anywhere that these addresses are used both by mIRC and scripts.
2) The "r:" prefix character will break use of these addresses if a client/script assumes that they consist of nick!user@host.
Basically, the ban list cannot be treated as a list of addresses any longer.
