Hi All,<o:p></o:p>
We have an Oracle ERP application which sends out bulk emails, I have created a separate receive connector for this , this application sends our bulk notification to all users, but we have found out after sending 10 to 20 emails it stops sending emails and throws our error<o:p></o:p>
On the oracle application this is the error which shows on logs <o:p></o:p>
SMTP transient error: 421 Service not available<o:p></o:p>
i am really confused of where to start from, is the problem from Oracle side or Exchange side? ,i feel it’s from the exchange side because the same application was working fine when we were in exchange 2010 now we have migrated to exchange 2013.<o:p></o:p>
