it mean? This error sent: 530 smtp authentication is required. message is not from your Exchange but from another email 530 smtp authentication is required gmail server installed on your local system: hMailServer. Don't confuse it with the similar worded "530 https://www.hmailserver.com/documentation/v5.5/?page=reference_error_messages_smtp 5.7.1 Client was not authenticated" message - that one IS from Exchange. If it is indeed "530 SMTP authentication is required" then POPcon tries to reach your Exchange Server on IP http://www.servolutions.com/support/articles/530SMTPauthenticationisre.htm port 25 (SMTP) but instead this other mail server answers with this particular error message. You need to either remove hMailServer from the system and restart Exchange or move one of the two servers to a different local IP port since both can't coexist on port 25. You can select the IP port that POPcon tries to reach on the EXCHANGE configuration page in the POPcon configuration.

They have a couple of domains where mail follows a slightly weird path: Users connect to an Exchange server to send e-mail The exchange server relays the message to an ISP-owned SMTP server as a smart host The ISPs server delivers the mail to the mail exchanger specified in DNS The mail exchanger is another server that runs hMailServer The Exchange server connects to the hMail server via POP3 and retrieves the messages. The problem arises when they send mail between addresses in the same domain, or two addresses that are present on the hMail server. hMail requires SMTP authentication when sending from local to local addresses, so the messages don't arrive. Removing SMTP authentication isn't really an option, as the server has been the target of spam being sent from spoofed local addresses. SMTP authentication prevents this. It is possible to add the ISP's mail server as an IP range with specific rules, but this seems inelegant. Bearing in mind I only have access to the hMail server and not the Exchange server, is there a better way of going about this? windows smtp share|improve this question asked Apr 12 '12 at 13:19 toryan 1761315 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote Are the users sending mail via an Exc
