tSendMail Can't send command to SMTP host

[KrupalGharat]

Hi,

I am trying to send mail using tSendMail component, but getting the following error:

[FATAL]: projectname.jobname - tSendMail Can't send command to SMTP host

Following is the error stack:

[INFO ]: projectname.jobname - talendStats_CONSOLE - Printed row count: 1.
Exception in component tSendMail

Hi
Which SMTP provider do you use? Take a look at a similar issue on stackoverflow, have a try to check the 'STARTTLS Support' box on tSendMail component.
