One or more recipient addresses do not receive emails from Appian via the Send Email node. The SMTP logs show the following error:
<IP_address> is not allowed to send mail from <domain> (in reply to RCPT TO command))
The SMTP server that is configured with Appian is not on the allowed list for the recipient’s email server.
The recipient’s email server needs to be configured to allow emails from Appian’s SMTP server. Alternately, emails from Appian can be rerouted to an SMTP server that is on the allowed list for the recipient’s email server.
This article applies to all versions of Appian.
