Well, I tryed to define smtp_bind_address=y.y.y.y but that didn't work, maybe because I had the same default router for both IP (x.x.x.x and y.y.y.y). Or maybe the nat rule in iptables is causing the redirection to x.x.x.x. Anyway, I'll test again without iptables. -- Sin otro particular se despide, Gabriel Möll Ibacache Ingeniero Civil en Computación
