Is it a need to register the reversed IP address ? My existing design is

Exchange --> Smart Host --> Internet

Exchange has been registered with

mail.abc.com   1.2.3.4

Suppose the smart host is using 5.6.7.8, in this case, should I only need to register reverse IP 1.2.3.4 to mail.abc.com, or 5.6.7.8 to smart host, or both ??

To fight the spam world it would be best to register both. You can use DNS Stuff to verify your settings once you are complete.

Is the Smart Host something you control? If not, you won't be able to register that anyway.

Changes like this are, in most cases, done through your ISP as they look after your network connection and therefore have responsibility for the reverse lookup zone in DNS.

If all mail flows out through the Smart Host then you do not need to register a PTR (Reverse Lookup record) at all. It might still be a good idea to do so for consistency though.
