open port 587 for smtp?

[techmanvt]

MS Exchange 2007 requires port 587 open for SMTP traffic - I see how to open non standard ports of my TZ 210, but nowhere can I find directions for allowing SMTP traffic through that port - SMTP is not one of the available protocols the Sonicwall will let me choose. Do I just open it for TCP/IP traffic and that will let SMTP through, or am I missing something here?

Thanks

In short yes. . SMTP is built on TCP/IP, being an aplication layer protocol.

SMTP over port 587 means you need TCP on port 587 allowed on the firewall.
