Our mail server utilizes an anti-spam technique (among many others) called Greylisting which helps prevent upwards of 90% of all spam from being delivered to your Inbox. If the sender’s email address seems otherwise okay but our mail server does not recognize the sender as either a Trusted Sender or as having sent email to you in the past 288 days (10 months), then we ask the sender’s mail server to please try again in 120 seconds. This waiting period is called Greylisting and is really effective at stopping spam because  most spammers do not attempt redelivery, whereas legitimate mail servers are required to attempt redelivery a minimum of 4 times. A two minute waiting period for an email from an unrecognized sender might seem to be an inconvenience but Greylisting can be 90% effective at reducing spam as spammers have more than plenty Junk E-Mail to deliver elsewhere to bother returning 120 seconds later to deliver just to you.

Some sender’s mail servers may not attempt redelivery right away, and may wait for 5, 10, 15, or even 20 minutes before the next retry, causing a more noticeable delay in delivery.

You can circumvent Greylisting on a specific email sender or sender’s entire domain by logging in to your web-based mail account at https://smartermail.scarabmedia.com and adding them to your Trusted Senders list under the Settings section.

Greylisting can be also be entirely disabled on your account, if you desire (although it is not recommended). To do so, log in to your web-based mail account at https://smartermail.scarabmedia.com and go to Account Settings under the Settings section and enable the checkbox “Disable Greylisting“. Be sure to click on the [SAVE] button to retain your changes.
