Whitelist blacklist email address
A whitelist and blacklist are lists of email addresses or domains that are either allowed or blocked from sending or receiving emails.
Whitelist:
A whitelist is a list of email addresses or domains that are allowed to send or receive emails. When an email address is added to a whitelist, it means that the email server or email client will accept emails from that address without flagging them as spam or blocking them.
Whitelisting is often used to:
- Allow specific senders to send emails to a particular email address or domain
- Allow emails from specific domains or IP addresses to bypass spam filters
- Allow emails from specific senders to be delivered to a specific folder or label
Blacklist:
A blacklist is a list of email addresses or domains that are blocked from sending or receiving emails. When an email address is added to a blacklist, it means that the email server or email client will block or flag emails from that address as spam.
Blacklisting is often used to:
- Block spam emails from known spammers or malicious senders
- Block emails from known phishing or malware senders
- Block emails from unknown or unverified senders
Examples of Whitelists and Blacklists:
- Spam filters like SpamAssassin or SpamFilter use blacklists to block spam emails
- Email providers like Gmail or Outlook use whitelists to allow emails from specific senders or domains
- Some companies use whitelists to allow emails from specific customers or partners
- Some countries or organizations use blacklists to block emails from specific countries or domains
How to Whitelist or Blacklist an Email Address:
To whitelist or blacklist an email address, you typically need to:
- Check your email provider's settings or configuration
- Look for options to add or remove email addresses from the whitelist or blacklist
- Enter the email address or domain you want to whitelist or blacklist
- Save the changes
Note that whitelisting and blacklisting can be complex and may require technical expertise. It's also important to ensure that you're not blocking legitimate emails or allowing spam emails to pass through.
