UNKLINE

Usage: UNKLINE <ident@host>
Will remove a kline from your server. You can NOT use wildcards to erase multiple klines at one time, the mask specified must be an exact match.
Examples:
/unkline *@*.aol.com
This undoes the KLINE command. It is generally good to remove klines periodically. Klines will often ban people who did not do anything wrong, and people will often start behaving when given a second chance. It's a good idea to keep track of anyone who is being repeatedly klined so that stronger measures can be taken or the kline can be kept.
