If what you were looking for is a Gmail checker, then you can use this script I've whipped up:

/*

Usage: /checkgmail <email>

Example: /checkgmail johndoe@gmail.com

Requirements: mIRC 6.14 or higher

*/

Code:
 [color:red]  [/color] 
alias checkgmail {
  var %e = echo -ac info * Gmail checker:
  if (!$0) { %e you must specify an email address. | return }
  set %gmail.email $1
  if (!$($+(%,gmail_,$1,_cookie),2)) gmail_getcookie 
  else {
    if (!$window(@gmail)) window -h @gmail
    %e checking for unread emails on account $1...
    sockclose gmail
    sockopen gmail mail.google.com 80
  }
}
