Greylisting
Your box uses a technique called greylisting to cut down on spam. Greylisting works by initially rejecting mail from people you haven’t received mail from before. Legitimate mail servers will attempt redelivery shortly afterwards, but the vast majority of spam gets tricked by this. If you are waiting for an email from someone new, such as if you are registering on a new website and are waiting for an email confirmation, please be aware there will be a minimum of 3 minutes delay, depending how soon the remote server attempts redelivery.
+tag addresses
Every incoming email address also receives mail for +tag
addresses. If your email address is you@yourdomain.com
, you’ll also automatically get mail sent to you+anythinghere@yourdomain.com
. Use this as a fast way to segment incoming mail for your own filtering rules without having to create aliases in this control panel.
Use only this box to send as you
Your box sets strict email sending policies for your domain names to make it harder for spam and other fraudulent mail to claim to be you. Only this machine is authorized to send email on behalf of your domain names. If you use any other service to send email as you, it will likely get spam filtered by recipients.
