Not receiving email after setting MX records

Question

I have domain on Bluehost named example.com and I am hosting it on AWS. I have setup an email account on Bluehost and added its MX record in AWS:

"example.com" "0 mail.example.com"

But still I am not able to receive any email on my account but I am able to send it. What are the points I have ignored?

Where is the DNS for the domain hosted? it is there that you need to edit the records. It also takes between 1-48 hours for it to take effect. — Simon Hayter♦, Jan 9 '17 at 10:36
DNS are hosted on AWS Route53 and my domain is present on bluehost — Ishan Sharma, Jan 9 '17 at 11:11

Check that:

The mail.example.com address points to your mailserver IP address. (You can look up the IP at https://www.whatsmydns.net/ by searching for the A record for that domain.)

If you see no IP address for that domain, you'll have to add an A record for your mail.example.com address that points to your mailserver's IP address, or a CNAME that points to Bluehost's email domain. Bluehost should provide the mailserver IP or domain in your email setup instructions.
Your CNAME and MX records have propagated. A search at https://www.whatsmydns.net/ for the MX record of example.com should return your mail.example.com address worldwide. You should also see the mailserver IPs when you search for the A record for mail.example.com.
Confirm that Bluehost have completed setup of your mail account.

Nick, I have done it in the same way as you mentioned like:- 1. Created a new MX Record like 10 @ mail.example.com 14400 2. I have created a new MX record in AWS Route 53 with domain example.com and added MX record as above. Still there is no luck ? – Ishan Sharma Jan 9 '17 at 12:03
@IshanSharma Have you confirmed that mail.example.com points to your mailserver IP? – Nick Jan 9 '17 at 12:29
I have pointed *.example.com as A record to instance IP of AWS, Is it correct ? – Ishan Sharma Jan 9 '17 at 12:43

That is correct if your subdomains are also hosted with AWS. But your mail.example.com domain needs to point to your mailserver with Bluehost if that is where your email is hosted. You can either: (a) set the A record for mail.example.com to point to the Bluehost mailserver IP and leave your current MX record unaltered, or (b) set your MX records to point to the Bluehost mail server address directly instead of to mail.example.com. Personally I would choose option (b) and set your MX records to whatever mail domain Bluehost recommends that you use. – Nick Jan 9 '17 at 12:53
