SUMMARY

How to configure email clients to access MailEnable's POP or SMTP.

DETAIL

Ensure the correct credentials are being used to authenticate against MailEnable. MailEnable services require that credentials be in the following format MailboxName@PostofficeName . MailEnable can also be configured to assume a default post office name as part of the username. This means that any user credentials without the @PostofficeName suffix will use the {@DefaultPostofficeName} suffix. The default post office can be configured under the properties of "localhost" in the MailEnable administration program.

Please this article for more information on MailEnable credentials: Article ME020068

When entering the incoming and outbound server name (for POP and SMTP) use either a domain name which resolved to the IP address of the mail server, or the IP address itself. These domain names determined by what has been created in the DNS for the domain (e.g. you can only use pop.domain.com if you have actually configured this in your DNS).

If using POP or SMTP to access MailEnable, ensure that the mail client does not have Secure Password Authentication or Authentication enabled over SSL. The following screen capture of Outlook Express outlines the correct settings (the mail servers and account name will be your own). This screenshot also shows that the email client is configured for SMTP authentication because the 'My server requires authentication' checkbox is selected. This is required if the server has been configured for SMTP authentication by having the 'Allow relay for authenticated senders' checkbox enabled in the SMTP Relay Properties.

Also ensure that mail client settings are not configured to use SSL. The settings for Outlook Express should be as outlined in the following screen capture:
