    Two things:

    You need to create an A record for mailserver01.abc.com.

    Did you use private IP addresses for your records? If so, your hosts will be accessible only in your LAN, not from outside.

    You must point your DNS records to your router's public IP address and configure your router to forward all needed ports (like 25 for SMTP, 80 for HTTP, 110 for POP3) to your internal servers.
