Inbox is Full
If the bounce back message indicates something similar to, "Inbox is full" or "Quota exceeded", then you've sent an email to someone whose email account is full. That receiving user will need to resolve that issue with their email provider. Deleting old emails or increasing the inbox quota will usually resolve this.
Email Account/User Does not exist
If you receive an error stating the email account (may be referred to as user) you sent to does not exist, double check your spelling of the email address as misspellings are common.
IP Address is Blacklisted/Blocked
The bounce back message will typically refer to an IP address being blocked and will usually provide a url with more information as well. We ask that these types of bounce back messages be forwarded to us by placing a ticket to our support dept at : http://portal.myresellerhome.com/submitticket.php?step=2&deptid=1
so that we can assist you in resolving this issue. You can also confirm whether your IP address or domain name is blocked by using our free online blacklist checker.
Greylisting/Message Deferred
Typical messages due to greylisting will usually refer to an email message being "deferred." Greylisting is a methodology utilized by some mail servers to deter spam. If you send a message to a server that uses greylisting and you are not on that server's whitelist the receiving server will "temporarily reject" that message and will often return a message that is formatted very similar to a bounce back but will list the error as temporary instead of permanent. The sending server will attempt to resend the message at a later time, but the recipient will experience a delay in receiving the message. The best way to avoid greylisting is to ask anyone who uses greylisting on their server to add you to their whitelist so they can receive messages from you without delay.
Send Limit Exceeded
On all of our servers, the number of emails that can be sent per hour is limited to 300 per hour If you attempt to exceed that amount you will receive a bounce back that will say something similar to: "Domain domain.com has exceeded the max emails per hour (300) allowed.
