uline_nickhost

You're probably familiar with the idea of having to do /msg NickServ@services.my.net as opposed to just /msg NickServ. This can be helpful to counter bots that try to auto-reg their nicks to join channels with +R set. ;]

Simply load the module and everyone will have to address all U-Lines with the above format. So if your services link's name is baste.my.hams you'll have to use /msg NickServ@baste.my.hams. This goes for both PRIVMSG and NOTICE (also includes CTCP as that's just PRIVMSG wrapped in special characters).
