Unable to Connect to SMTP using TLS from Siebel
Hi Folks,
We are unable to connect to SMTP server (Microsoft Exchange 2010 SP3 Rollup 26) which uses TLSv1.2. Attached the IMAP SMTP log after the enabling log debug.
Following are the troubleshooting steps already performed. Any input is greatly appreciated.
1) Able to connect to the same SMTP server and send an email from the Siebel Server machine using OpenSSL.
2) Able to connect to the same SMTP server and send an email from Java using JavaMail API.
3) SSEP is installed and the sslcnapi128.dll from SSEP folder is copied to BIN folder and renamed to sslcnapi.dll.
4) Able to connect to the same Exchange server and retrieve messages using the IMAP protocol.
