At first, we set everyone’s mailbox to a very low spam protection setting. Starting on Feb 1, 2018 and then the first work-day of each month thereafter, until we reach the highest protoction protocol, we will be increasing the Anti-Spam protection setting by one step. We have 5 steps to take us to the maximum protection level. You will see more mail going to your spambox as we increase these protocols. This slow increase of protection will give you time to build your whitelist so that you don't miss any important email.
These settings are for all @netonecom.net mailboxes. We cannot tailor this to individual email accounts. They affect everyone as a whole.
Teaching the filter what is or is not spam.
IMPORTANT NOTE: you must use the Roundcube version of webmail for the report and it's features to work properly. SquirrelMail and Horde are not compatible with this functionality. They look like they work, but do not send the proper pieces to be processed so the email will not get whitelisted like you want.
If ASSP thinks an email MAY be spam, the system sends an “allow through” response message back to the sender that looks like a bounced email message. The email will contain a code at the end of the message. If the sender re-sends the same email with this code added in the subject, the email will be allowed through the filter. This happens frequently with new senders that include attachements until the system learns who you trust.
Please note that the system updates the spam and whitelist entries immediately but the not-spam is only processed once a day. Once an email domain or address gets onto the spam list, you may need to whitelist and/or not-spam it several times to get it to clear. It will depend on the severity of the ‘spam’ value for that email address or domain. The higher the score the harder it is to clear. The whitelist method should clear it up right away, but may still take 24 hours before it fully clears it due to the not-spam processing.
