Hello, I have configured a standalone server where the e-mail server is a hMailServer. When I try to test the SMTP connection, it fails with a 501 error, because the K2 server is sending the commando EHLO without a server name. Is there any place where I must configure this server name?
Best regards
SMTP can be quite tricky, it took me a while to get SMTP and Exchange SMart Actions to work on the same server.
For starters. the SMTP magic all happens in the connectionstringeditor, have you set that up correctly?
Hello, yes, I think I have the connection string well configured. In fact, I can connect with the SMTP server. The problem is that K2 isn't following the protocol, because it is sending the EHLO command without the domain name:
