Sender Whitelist/Blacklist
This refers to lists of email addresses / domains of people who are sending mail to the SpamExperts user.
Sender Whitelist (normally available at domain level)
All filtering checks are disabled for whitelisted senders. You can whitelist a specific sending email address, or a full sending domain. We recommend only using the sender whitelist if the system would otherwise wrongly block email from a certain sender. Spammers often use fake senders matching the recipient domain, or domains the recipient may have received emails from before, to try and bypass the filtering in that way. In addition, if the system is generally wrongly blocking a sender, you can always contact our customer support so we can research what problem is causing the rejection and resolve that issue.
Sender Blacklist (normally available at domain level)
Emails from senders listed on the blacklist will be automatically rejected. The messages are NOT quarantined. The messages are rejected with a 5xx SMTP error code, so legitimate sending SMTP servers will generate a bounce message to the sender.
Special Usage
You can whitelist/blacklist a specific sending email address, or a full sending domain. To whitelist/blacklist all senders from a domain, you should only enter the domain (without *@).
Recipient Whitelist/Blacklist
This refers to lists of email addresses / domains of people (SpamExperts users) to whom mail is sent.
Recipient Whitelist (normally available at domain level and email level)
Filter checks are disabled for listed addresses; Email directed to whitelisted recipients will bypass all filters. Recommendation is to use only for exceptional cases such as abuse@ or postmaster@.
Recipient Blacklist (normally available at domain level)
Emails to recipients listed on the recipient blacklist will be automatically rejected. The messages are NOT quarantined. The messages are rejected with a 5xx SMTP error code, so legitimate sending SMTP servers will generate a bounce message to the sender.
Special Usage
To whitelist/blacklist a specific recipient address, the local part of the address should be entered. For example if your domain is mydomain.com and you add ‘nofilter’ to the recipient whitelist, all emails sent tonofilter@mydomain.com will not be scanned for spam. To whitelist/blacklist all recipients for a domain (so all emails sent to the domain are not scanned/blocked), you can enter the wildcard * for the local part.
