Dear Experts

CRM system work flow triggers emails to the prospect email account as and when the prospect statues changes via the SMTP server ( without password that is without authentication as it is Relay server hosted locally-office 365 mail protection ). We could see the connection to the email server getting established but no packets sent/received , but through telnet we can send and receive mails by making use of from and to email commands through the telnet session, can you help where the things are going wrong. following SL2 cases it works but SL3 it does not work.
1. though telnet to the smtp server with FROM and TO commands it works that is mail is delivered to the TO addressed account.
2. though CRM system configure email settings with email account, smtp and port without the SMTP authentication mail is getting delivered to the To account.
3. CRM system through workflow trigger email on each status changes mail is not getting delivered instead we can see connection is ESTABLISHED to the smtp server
