IPv4 addresses are numbers (uint4 to be precise), dotted quad notation is
just the most-human-readable way to represent them. It is valid to
represent an IPv4 address as a 32-bit hex value.

You should look at your trusted_networks settings if this is a local
network client, and should consider using authenticated SMTP if it's a
remote trusted client.

Posting full headers from a sample message would help.
