SUMMARY

How to configure email clients to access HTTPMail.

DETAIL

The Professional and Enterprise Editions of MailEnable include an additional mail service called HTTPMail. HTTPMail allows access to mail from the server without downloading the mail (as is often the case with POP). HTTPMail provides similar functionality to IMAP, whereby Outlook Express, Outlook 2000/2002/2003/2007 (NOTE: Vista Windows Mail and Windows Live mail client do not support the HTTPMail protocol) clients can access and manage messages and folders on the server. Unlike IMAP, it does not require SMTP to send messages as it posts messages directly into the server mail queues where they are either locally delivered or dispatched through the SMTP Connector.

Another advantage that HTTPMail has over using POP and SMTP is that it can be configured to operate over Port 80, meaning that mail can be accessed through corporate firewalls.

If HTTPMail was installed during the installation process, the service is published on Port 8080 of the server.  This setting can be changed to an alternate port, but 8080 is the default so that the service does not conflict with any existing web services that may be running on the server. 

Using Outlook Express, Outlook 2000/2002/2003/2007 as a mail client, it is possible to select the mail protocol as HTTP and enter in the following details:

My incoming Mail Server is a HTTP server
My HTTP mail service provider is: Other
Incoming mail (POP3, IMAP or HTTP) server:
http:// Your Server:8080/MEHTTPMail

Since HTTPMail is an authenticated service, it requires the usual account credentials when prompted (e.g. mailbox@postofficename ).
