Can you provide actual information about your bug report? You have mentioned there was an incorrect link but it's not clear what the link is, which makes it basically impossible for this bug to get fixed.
Was what you saw only "admin@" with no suffix?
Note that mIRC adds email addresses to the URLs list if you tell it-- if there was a suffix, this is a feature, not a bug. You can disable this in Alt+O -> IRC -> Catcher
