Also, an IP is not "dynamic" for email purposes if it has a valid
HELO (i.e. looking up the alleged hostname matches the connect IP).
Many ISPs will not (or the process is inordinately expensive timewise)
assign rDNS for small static IP allocations, even for business accounts.
The whole point of HELO is to provide a verifiable hostname for exactly
this situation.
