Can you ping the antispam device from the firewall? Can you ping it from the SMTP server? In the configuration you described the switch will not do any packet forwarding between VLANs, the antispam box has to do IP forwarding/routing in this case.

 Thanks Marco for your reply, 



This configuration work ok in 3300 with vlan1 default and vlan2 antispam, but when I change to 4400 with the similar vlans vlan1 and vlan2 it's not work and I don't understand, why work in 3300 and not in 4400?



In 4400 I have ping the antispam from firewall and the SMTP server don't ping to antispam. In 3300 is OK

And you not only have configured the VLANs as such but also assigned them to the appropriate ports where your antispam device and mailserver is plugged in?

 Hello Marco, the switch was out of order, I change it and all is Ok, thanks. I don't like 4400 model, I had tried  with 3 items to found one which work OK.
