Our ISP is requiring us to switch our SMTP traffic from port 25 to port 587.  I wanted to permit this on my firewall, so I simply mimicked the configuration for port 25.  Would this work?

access-list 101 extended permit tcp any host eq smtp
static (inside,outside) tcp interface smtp smtp netmask

access-list 101 extended permit tcp any host eq 587
static (inside,outside) tcp interface 587 587 netmask
