I would like to know how we can change the domain of Sender Email Address. For instance, we have sender email address as "email@example.com" and we would like to change it to "firstname.lastname@example.org". Is this possible to change it in SMTP email settings in TM.
Or, if not, how can we set the from address in the delivery service? I tried changing the from address but i encountered an error:
"ERROR com.sun.mail.smtp.SMTPSendFailedException: 554 Message rejected: Email address is not verified. The following identities failed the check in region US-WEST-2"
