un tā tālāk, visam pa vidu smuka bilde  - kā nu kuro reizi - ar visādiem erotiskiem medikamentiem utt.

Varbūt kāds var paskaidrot, kā tā lieta darbojas, jo katru reizi it kā no citas personas un cita e-pasta nāk, bet pēc satura redzams, ka laikam autors ir viens un tas pats (laikam jau kāds automāts uzlikts) Vai var kaut kā noteikt īsto adresi, no kurienes tas nāk?
