Маркет Writing the subdomain address instead of the e-mail domain

An email domain is written in an ad. But this is pretty useless. For example, it detects and writes each of 3 different domains belonging to firstmail as a domain. But it should write the main server address.

For example;

firstmail*ltd instead of fmailler*com
firstmail*ltd instead of fmaillerbox*net
or rambler*ru instead of ro*ru
hotmail*com instead of hotmail*edu*fr
hotmail*com instead of hotmail*es

(* To prevent url links from being created)
