The recipient address is not a valid RFC-5321
Question
Email

Hi,

I am encountering Error:-  118: 553-5.1.3 The recipient address <smtp.gmail.com> is not a valid RFC-5321 

I checked the TO parameter in the Send Email Object and I know that I entered the correct email address.

Any advice on this?

Thank you

This looks like an SMTP server error. How did you configure your SMTP?

Once you try this 

or

The fully qualified domain name of the SMTP service is smtp-relay.gmail.com. Configuration options include: Port 25 or 465
