Introduction

BLP is a command introduced with MSNP2.

It is a Notification Server command, without either a request or response payload.

It modifies if messages sent to you by users not on your Allow List (AL) are allowed to be received.

Client/Request

BLP TrID [ AL | BL ]

Server/Response

BLP TrID {list-version} [ AL | BL ]

Where list-version is the new List Version. Removed since MSNP10 in ABCHMigrated: 1 mode.

Examples

Setting to AL (Allow messages by default)

C: BLP 1 AL
S: BLP 1 256 AL

Setting to BL (Block messages by default)

C: BLP 2 BL
S: BLP 2 257 BL
