I have got a DSL from the ISP, having a static IP.
Can I run postfix with this IP for accepting email for my own domain?

If you've got a static IP and there's no games being played, it should

Fred and Richard are of course correct, but you are very likely to
have problems sending mail from a residential IP netblock. See if
you're on PBL:

If your ISP will set a custom PTR record for your IP address, you
can remove yourself from PBL. If not, you can possibly receive at
your home IP address, but you would have to relay outbound through
a VPS. Or, upgrade to business-class service from your ISP. Most
often a VPS is cheaper.
if an ISP is willing to set reverse DNS of statically assigned IP to
something customer wants, it should not be required.
so, look your reverse DNS (generic names are often blocked at many isps)
and optionally ask your ISP to change it to somethint that points to your
IP.
you'll want non-generic name like mail.example.com.
