The reverse DNS for domain

A particular sender domain can't send out an email to us. From their finding, it says that our domain abc.com don't have any A record.

Is it necessary to register our email domain abc.com to a IP address ? Should I set the A record for abc.com to our antispam gateway ?  Please note that the antispam gateway will receive public email before forwarding to our exchange server.

Thx

Many mail filters will reject messages if they can not confirm the sending server using a reverse DNS lookup.  

If you are the sending party then you need to work with your public DNS provider to ensure your DNS has the proper revers lookup zone as well as reverse lookup records for your MX records.  Your DNS provider can help with this.

If you are the receiving party you should ask the sender to check their reverse lookup or you can white list them in your spam filter.

I can not provide exact instructions on how to do either as these depend on the service/ provider.

You need to ask your ISP to setup appropriate reverse DNS for your IP addresses.

Unless your ISP is also your DNS hosting provider, your DNS hosting provider is not able to configure reverse DNS for you.

Arne is correct, because your IP addresses belong to your ISP, it is they who need to create the rDNS record.

Try using http://www.mail-tester.com as it can identify many issues from your side of things.

the A record for the domain should point to he primary web server for the domain, it does not need to point to the MX record

The only records that need reverse DNS are the IP addresses associated with the A records for your mail server(s). Although these are usually your MX records, they do not have to be, you can send and receive on different hosts.
