- How did you hear about Mailcleaner: used to use it
I have imap clients that are configured to receive mail from their imap server (hosted at ISP) and configured to send outbound mail via the (offsite) mailcleaner server.
What is happening is that when one person in the office tries sending a mail to another person in the same office (Same email domain) they get a NDR reporting that :
SMTP Error 500. This domain does not accept mail from itself (spoofing)
Is there a way to configure Mailcleaner to allow internal users to send each other mail?
