Maybe the firewall is blocking or permissions issues.

Please refer this article https://www.ptc.com/en/support/article?n=CS236135

Yes Vibhuti. I can able connect the mail server via telnet. But not able send email with service.

Hello,

465 is an SMTPS port, so make sure you select "Use TLS" checkbox.

Showing error "Unable to Invoke Service SendMessage on MailServerThing : Exception reading response".

We made "Use TLS and Use SSL" both are true by that scenario facing an error link "

 Unable to Invoke Service SendMessage on MailServerThing : Could not connect to SMTP host: secure.emailsrvr.com, port: 465" 

Thanks.

@Sathishkumar_C Did you try "Use SSL" and "Use TLS" in all 4 possible combinations? Still the same error?

[Sathishkumar_C]

Hi Constantine,

I have attached the errors of possible combinations of  SSL and TLS. Email server is reachable which i have confirmed with telnet command.

SSL - true / TLS - true -> Unable to Invoke Service SendMessage on MailServerThing : Could not connect to SMTP host: secure.emailsrvr.com, port: 465

SSL - true / TLS - false -> Unable to Invoke Service SendMessage on MailServerThing : Could not connect to SMTP host: secure.emailsrvr.com, port: 465

SSL - false / TLS - false -> Unable to Invoke Service SendMessage on MailServerThing : Exception reading response

SSL - false / TLS - true -> Unable to Invoke Service SendMessage on MailServerThing : Exception reading response

Does it work for you when you configure some desktop client (e.g. Outlook, Thunderbird, etc.) with the same settings? Maybe your server blocks SMTP traffic or uses another port?..
