RoadRunner email has been experiencing issues lately, and it has frustrated users in a way that you couldn’t possibly imagine. Road Runner Web Mail is a reliable service provider, but nothing can be said as to when it will malfunction. The problem that we will be discussing in this blog post is related to the error messages that an inbound sender will come across. Many people see these errors and get scared because they don’t know what it is and how to resolve it. Let us find out all those error codes and what they mean.

  1. 550 5.1.1: Invalid Mailbox: (Your Name) @ (Area).RR.com: This error appears when the address of the recipient does not exist in the error message or he/she doesn’t have any active account.
  2. 552 5.3.4: Rejected message due to its large size: This error appears when the message that you have send is larger than what needs to be sent. There is a limit of 30 MB on the inbound messages.
  3. 554 Virus detected.
  4. 550 5.7.1: Message rejected as it contains virus.
  5. 554 5.7.1: Not allowing null sender with too many recipients. Though RR com mail accept messages from Null senders, but it limits certain messages to a single recipient. The use of Null sender is to deliver status notifications and identical messages. Responding to other messages, DSNs are sent, and as the message can have just a single sender, it is important that DSN must also have a single recipient.
  6. 553 5.1.2: The www RR com email address of recipient is not local.
