all i did was creating both NS ns1.domain.ro. ns2.domain.ro. i enablesd the website mail.domain.ro , of course i changed the alias directory directly to squirrelmail folder, and now it s ok

thanks anyway for the advice, the problem is that for the 2 older domains i have everything is ok, only for the last domain it wasn t working.
now it s working fine .. i really dont understand where the problem was ...
thanks anyway, as allways very quick reply
