How to know mail server of a domain

There are a few ways to find the mail server of a domain:

  1. MX Record Lookup: You can use a DNS lookup tool or a website like MXToolbox or WhatIsMyMXRecord to look up the MX records for a domain. MX records contain information about the mail servers responsible for receiving email for a domain. You can enter the domain name and the tool will return the MX records, including the mail server names and their priority levels.
  2. WHOIS Lookup: You can perform a WHOIS lookup on the domain name to find the domain's registration information, which may include the mail server information. You can use a WHOIS lookup tool or website like Whois.net or DomainTools.
  3. Email Header Analysis: When you receive an email from a domain, you can analyze the email header to find the mail server information. The email header will contain information about the mail servers that handled the email, including the mail server names and IP addresses.
  4. Contact the Domain Owner: If you have a legitimate reason to know the mail server information, you can contact the domain owner or administrator directly and ask for the information.
  5. Check the Domain's DNS Records: You can check the domain's DNS records to find the mail server information. The DNS records may include the mail server names and their IP addresses.
