I'm getting a server error when trying to send an email to members in a recordset.This is triggered by an update transaction which works fine.
I've checked the email addresses are valid Also tried with the default server settings in in the control panel and with my smtp details.
Can't think of anything else!
Email to user: was not sent. Error returned: E-mail couldn't be sent. Error returned: Failed to add recipient: @localhost [SMTP: Invalid response code received from server (code: 501, response: <@localhost>: no local part)]. (EMAIL_FAILED)
