We have a business parther who developed a application server for us. This application server will able to send an email to internal user. The application for sending mail require below settings: SMTPSender Port Username Password Domain I'm created a new mailbox for this application as SMTP: Send.contoso.com Port:587 Username:SIS@contoso.com.my Password:xxxx Domain:contoso.com They will above information to their application settings. On Exchange part, I created a new RECEIVE Connector and add the application server IP address and Authentication as TLS and External Secured, Permission: Exchange servers group. When they did sent test email from the application, there was error generated: 5.7.3 authentication unsuccessful 5.7.4 unrecognized authentication type Please advice 5.7.3

Their application require information like this link:http://www.codemeit.com/not-working/redmine-email-504-574-unrecognized-authentication-type.html

Since we only discuss the Exchange issue on the pure Exchange product environment in this forum and we do not have any resource about the developed application server, it’s highly recommended to contact the Partner for further assistance. Thank you for your understanding. Regards,Novak Wu-MSFT

I understand but I just need know how to give correct permission to "RECEIVE CONNECTOR" since you have internal application which we trusted the IP address and on coding side, it just put as below, it able to use Exchange to relay email $this->smtpHost = 'send.contoso.com'; $this->smtpUser = ''; $this->smtpPass = ''; $this->smtpPort = '587'; $this->linkpath = 'http://ess-las_edited.contoso.com'; //test $this->sendmailPath = '/usr/lib/sendmail -ti'; $this->mailType = 'smtp'; $this->mailAddress = 'sis@contoso.com';///email address for ess-las //$this->smtpAuth = 'LOGIN'; $this->smtpAuth = 'NONE'; $this->smtpSecurity = 'NONE'; But if the developer use:, Exchange unable to replay the email.I need advice how permission should I assign so that the Exchange able to replay email for application that using SMTP settings which including username and password config.action_mailer.smtp_settings = { :address => "send.contoso.com", :port => 587, :domain => "contoso.com", :authentication => :login, :user_name => "SIS", :password => "sapura2010", } http://msexchangeteam.com/archive/2006/12/28/432013.aspx
