Re: Exchange connector setup
Thank you all for your help, guys. For me, the solution was the following: A connector response with error 5.7.54 SMTP means an identification error. On the Security tab of this connector, set the following options Authentication: Externally secured and Permission groups: Exchange servers and Anonymous.2.1KViews0likes0CommentsExchange connector setup
Hello, dear colleagues. My organization has deployed Exchange version 15.1 Hybrid, which works perfectly. My job is to configure it to provide email notifications from the local Webcon server. In the current configuration, notices are successfully sent only to addresses within our domain, but you need to configure exchange also to send to external addresses. At this point, exchange reports an error for any external domains in this way: System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: 5.7.54 SMTP; Unable to relay recipient in non-accepted domain at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, Boolean allowUnicode, SmtpFailedRecipientException& exception) at System.Net.Mail.SmtpClient.Send(MailMessage message) at WebCon.WorkFlow.Service.AttachmentsProcessing.Helpers.EmailsSender.Send(SmtpClient client, MailMessage mail, Int32 probe) at WebCon.WorkFlow.Service.WCFService.WCFService.TestMailSend(TestMailSendArgs args) I tried to configure the Inbound connector as follows: Role - Front-End-Transport Type - Internet Remote Network Settings - Webcon´s Local IP Address Network adapter bindings - All IP4Addresses, Port 25 On the "Security" tab, I only marked Anonym user. Judging by the server logs, mail passes through a connector I created, but the error message remains the same. Please tell me how I can correctly configure the connector to forward mail to external domains. Thank you so much in advance.Solved2.1KViews0likes1Comment
