Your IdentD contains 'X'. Try changing to all lowercase, or taking the X out of it. You can access this in mIRC options: ALT+O
next to the 'User ID' box.
You can also change it via the /identd command, use /identd on IdentHere
- make sure it doesn't have 'X' inside it though.
Once you've changed it, send them an email with your IP. Connect to another server and type //echo -a $ip
, and send that one. For a contact email, check any other parts of that message, or go to the network's website and look for an email address.
Remember, mIRC has nothing to do with bans from IRC servers or networks. You may wish to see this post
