SMTP

SMTP stands for Simple Mail Transfer Protocol. SMTP is used when email is delivered from an email client, such as Outlook Express, to an email server or when email is delivered from one email server to another. The port may be 25 or 587 depending on your SMTP.

IMAP

IMAP stands for Internet Message Access Protocol. It, too, is a protocol that an email client can use to download email from an email server. The IMAP protocol is designed to let users keep their email on the server. IMAP requires more disk space on the server and more CPU resources than POP3, as all emails are stored on the server. IMAP normally uses port 143.

In order to use the application to a full extent one must have existing domain details or they have to create a domain. Please create a domain of your own in any of the sites, there is a cost to create these domains which ranges from 99 cents onwards. Once you create a domain the next step is to set the mx value for that domain in the DNS settings. The vendor who provided the domain will give you access to the DNS settings through their console. Once you get this access set the public DNS name of the instance where you are running the Hmail server in the mx value and set the priority to 10.
