If you have a static IP from Charter or Comcast it is probably *not* on
the black lists;  these networks separate their dynamic and static
ranges and publish those ranges appropriately.

If you are attempting to host *anything* on a dynamic IP - don't.

There isn't anything special;  a static IP should be able to receive
connections on port TCP/25 without any issues.  I do this on static
Comcast customers,  don't recall if I've done so on Charter.   Otherwise
if the last-mile network is a concern SMTP is trivial to host on
something like a Linnode or you can get excellent hosting on Open
[standard compliant] from companies like FastMail.fm
