Mail lookup settings

Mail lookup settings refer to the configurations that determine how email addresses are looked up and resolved in an email system. Here are some common mail lookup settings:

  1. DNS Lookup: This setting determines how the email system looks up the IP address of a domain name. Common DNS lookup settings include:
    • MX Record: Looks up the Mail Exchanger (MX) record for a domain, which specifies the mail server responsible for receiving email for that domain.
    • A Record: Looks up the IP address associated with a domain name.
    • CNAME Record: Looks up the canonical name (CNAME) record for a domain, which specifies an alias for a domain.
  2. Mail Server Settings: These settings determine which mail server to use for sending and receiving email. Common mail server settings include:
    • SMTP Server: The mail server used for sending email.
    • POP3/IMAP Server: The mail server used for receiving email.
    • Authentication: The method used to authenticate with the mail server, such as username/password or SSL/TLS.
  3. Email Address Resolution: This setting determines how the email system resolves email addresses. Common email address resolution settings include:
    • Local Delivery: The email system checks if the email address is local (i.e., on the same server or domain) and delivers the email locally.
    • Remote Delivery: The email system sends the email to a remote mail server for delivery.
    • Forwarding: The email system forwards the email to a different email address.
  4. Spam and Virus Protection: These settings determine how the email system handles spam and viruses. Common spam and virus protection settings include:
    • Spam Filtering: The email system checks incoming email for spam and viruses and blocks or quarantines suspicious emails.
    • Virus Scanning: The email system scans incoming email for viruses and blocks or quarantines infected emails.
  5. Email Routing: This setting determines how the email system routes email messages. Common email routing settings include:
    • Domain Routing: The email system routes email messages based on the domain name of the sender or recipient.
    • User Routing: The email system routes email messages based on the email address of the sender or recipient.
  6. Email Authentication: This setting determines how the email system authenticates email messages. Common email authentication settings include:
    • SPF (Sender Policy Framework): The email system checks if the sender's IP address is authorized to send email for a particular domain.
    • DKIM (DomainKeys Identified Mail): The email system checks if the sender's domain is authorized to send email with a particular digital signature.
    • DMARC (Domain-based Message Authentication, Reporting, and Conformance): The email system checks if the sender's domain is authorized to send email with a particular digital signature and reports any unauthorized emails.

These are just some of the common mail lookup settings that can be configured in an email system. The specific settings and options may vary depending on the email system and its configuration.
