Ovo ne moze ovako. Ti si izabrao da ti lokalni IIS SMTP procesira mail, a dao si host pretpostavljam exchange servera. Ne znam zasto ti McAfee blokira (i ne mogu da verujem da neko jos to koristi dobrovljno

), ali jednostavan nacin da proveris mail kod je da posmatras IIS mail dump folder (obicno c:\inetpub\mailroot\drop) i vidi da li se u njemu napravi mail fajl, ako da onda nije nista do tvog .net koda i onda bi resenje lakse nasao u nekom drugom forumu.
