Error while sending mail.

[major]

I am getting the below error. This is working in dev region but is not working in another region. The SMTP server used here is working fine for other jobs. Please guide

What's different between dev region and other region? "Nothing" is not the correct answer.

The issue is resolved now.

there is an extra orphan word sneaked into the email to list.
We have removed that word and the sequence is running fine now
