Smtp Server Error 5.7.1

Core Operating System Division. Resolving SMTP error 550 5.7.1 Unable to relay for user@domain.com Error 0x800CCC79 ★★★★★★★★★★★★★★★ John Howard -MSFTOctober 11, 200515 Share 0 0 I was struggling with this error message today - everything I had found on the Internet suggested it related to security. Well, it does, of sorts, and a careful look at the configuration of your SMTP server without mis-interpreting a dialog box. If you open the properties for your SMTP server under IIS admin, select the Access Tab, and at the bottom, click "Relay", you will see a check-box at the bottom, which is by default selected, saying "Allow all computers which successfully authenticate to relay, regardless of the list above". In my head-scratching to work out the cause of the error, I had mis-read the message as "Allow all users which succ….". The answer therefore was simple, above that check-box on the relay restrictions tab, there is a options dialog which by default Only the list may relay. Simple as adding your server to the list, or selecting All except the list below. The first one is obviously more secure.

for error code 5.7.1 in Office 365 Applies To: Office 365 Admin More... Less Have you ever sent an email message in Outlook or Outlook Web app and received an Exchange NDR error message about why your email couldn't be sent? This topic will walk you through the steps of what to do if you get delivery status notification (DSN) error code 5.7.1 or Exchange NDR 5.7.1 in a non-delivery report (NDR). This information also applies to error codes 5.7.0 through 5.7.999 in Exchange Online and Office 365. There can be several causes for dsn error code 5.7.1, for which solutions are provided later in this topic. Email user help if you sent a message and then received Exchange NDR https://blogs.technet.microsoft.com/jhoward/2005/10/11/resolving-smtp-error-550-5-7-1-unable-to-relay-for-userdomain-com-error-0x800ccc79/ 5.7.1 or 5.7.0 through 5.7.999 There's reasons you might get these error messages. Generally, the error indicates that your organization has a security setting for emails that is preventing your message from reaching the recipient. It might be one of the following problems: You don’t have permission to send to the recipient. You don’t have permission to send to the distribution group or one of its subgroups. You don’t have permission to send email through an https://support.office.com/en-us/article/Fix-email-delivery-issues-for-error-code-5-7-1-in-Office-365-da1ff375-f88f-4a3e-b81f-06cdb6ecae3c email server that’s between you and the recipient. Your message was routed to the wrong email server. Tips for fixing the problem that is causing DSN error code 5.7.1 or 5.7.0 through 5.7.999 Most of the time, you probably won't be able to fix this problem on your own. Either the recipient or the recipient’s email administrator has to update their email settings. However, here are a few things you can try. If the recipient is outside of your organization    - Ask the recipient to ask their email administrator to set up the mailbox so that it accepts email from you. If you’re sending to an internal distribution group    - You might not have permission to send to the group or to one of its subgroups. In this case, the NDR includes the names of the restricted groups that you don’t have permission to send to. Ask the owner of the restricted group to grant you permission to send messages to it. If you don’t know the group’s owner, you can find it by doing the following in either Outlook Web App or Outlook. Select the NDR 5.7.1 message. In Outlook Web App, choose the group name located in the To line. In Outlook, double-click the group name. In Outlook Web App, from the pop-up dialog box, choose Owner. In Outlook, choose Contact.

Mailbox Recovery, Exchange Server Recovery No Comments While working on Exchange Server with MS Outlook, the users often bump across the following error message when they try to send emails outside their domain: “550 5.7.1 Unable to Relay” Cause: Error 550 occurs when emails are sent to a domain other than the user's. This error signifies that the outgoing mail server fails to recognize the sender. This means that the users are not authenticating to the server and hence, they are not allowed to send emails. The second possible reason could be the absence of the recipient policy for that domain in the user's department. Exchange Database (EDB) corruption is another factor that generates the above error. Resolution: The aforementioned error message can be resolved by these solutions: Solution1: Go to the Administrative Groups in the Exchange Server Manager. Select Administrative Group Name -> Server -> Server Name -> Protocols -> SMTP. Choose Properties option by right clicking on Default SMTP Virtual Server. Choose Access tab and click on Relay to select ‘only the list below‘. Now, add the IPs you want to relay and your domain. Finally check ‘Allow all computers which successfully authenticate to relay, regardless of the list above‘. Solution2: You can also figure out the various Exchange Server errors you encounter in the application event log and look for their resolve on-line. If the Exchange Error 550 is due to the result of database corruption, it can be repaired using Microsoft inbuilt utility Eseutil. In case after using the ESEUTIL utility the database is not repaired due to severe corruption then you need to devoir a third party Exchange Server Database recovery tool. Among the copious EDB repair tools available in the market, a reliable solution is “Stellar Phoenix Mailbox Exchange Server Recovery”. This powerful software is able to recover all the data fro
