As the message is rejected in the protocol, it isn't retrievable from the Administration Console and must be resent once the issue is addressed. These SMTP codes and reasons are communicated to the sending MTA. The 550 error number means that this is a permanent error, so resending it later will have the same effect. Error numbers that are in the 400's are temporary errors and can usually be tried again at a later time. The message itself indicates that the email address that the message was sent to does not exist. The Contract Address 0xAdfeC93860DC452CC5dfa9b82A8D1E1e016D550D page allows users to view the source code, transactions, balances, and analytics for the contract. It's frustrating when you get an error after sending an email message. This topic describes what you can do if you see error code 550 5.1.0 or 5.1.0 in a non-delivery report (also known as an NDR, bounce message, delivery status notification, or DSN). Use the information in the NDR to help you decide how to fix the problem. Incoming E-mail works. Outgoing bounces back almost instantly. I'm using Comcast mail server for both incoming and outgoing mail. We don't have our own domain name. Here is the relevant part of the NDR <vfhserver1.VermeulenFuner alHome.loc al #5.1.0 smtp;550 5.1.0 <[email protected] lhome.loca l> sender rejected : invalid sender domain>. 550 invalid address; 550 user has too many messages on the server; 550 permanent failure for one or more recipients; ... If you don’t have this option, then there’s nothing else to do other than try the sending again later. If the recipient was only temporarily unavailable, then the new attempt could be successful.. These connections are rejected in the protocol, and, the connection is logged in the Rejection Viewer. As the message is rejected in the protocol, it isn't retrievable from the Administration Console and must be resent once the issue is addressed. These SMTP codes and reasons are communicated to the sending MTA. The rejection message is 550 Invalid Sender [502]". But it is totally random as to which user it happens to and when it happens. This seems to happen with a specific extension emails only .ae all other emails are working fine, what could have gone wrong all of a sudden?.
