\"Star\"<\/a>In the coming weeks I’m going to be taking a, “Did you know?” approach to my blog as I keep running across items that are offered in our feature set that folks find surprising that we offer that would have saved them time had they known. These items are part of ExchangeDefender that folks don’t come across often but they are there. The first topic we\u2019ll touch are White listing and trusting senders. <\/p>\n

One of the more common inquiries that arise out of the Trusted Sender is why does it seem to not work consistently. Here\u2019s the logic behind the Trust Sender function in ExchangeDefender. Trust Sender will in essence white list that specific sender address to that specific recipient address. The times when folks over look these details and it turns into a problem are as follows: <\/p>\n

Domain administrators often \u201cTrust Sender\u201d from SPAM Czar under the assumption that the sender is being trusted for the domain, the feature set has not changed it will still white list that sender to that specific recipient. <\/p>\n

Senders that use disposable email addresses like carlos+is+cool+3425223@exchangedefender.com<\/a> work around the mechanism, since the from address is always different, so this type of sender is better suited for a domain level whitelist. <\/p>\n

That takes us to the options for whitelist formatting. ExchangeDefender will access the following types of entries: <\/p>\n

\n

user@domain.com Basic per user whitelist
domain.com Domain level whitelist
a.domain.com Third level domain whitelist
123.123.123.123 IP address whitelist
123.123.123 \/24 whitelist<\/p>\n<\/blockquote>\n

All this information can actually be found in our Knowledge Base inside of our support portal. <\/p>\n
