Internet Message Access Protocol (IMAP)

IMAP version 4 revision 1 ( IMAP4rev1 ) is the latest version of a very popular e-mail retrieving protocol, functioning over TCP/IP. Unlike POP3, IMAP keeps the e-mails on the server and only downloads them for viewing when requested by the client. The e-mails are never erased from the server unless requested by the client.

IMAP is a more resource demanding protocol for both the server and the client but this is offset by the many features it offers over POP3. Among them we have: flagging messages ( see which e-mails are read, unread, replied, forwarded ), organizing e-mails in folders, server-side e-mail searching and most importantly, preserving our messages and their structure regardless from which location we access it.

The IMAP4rev1 RFC can be found here

PolarisMail fully supports the IMAP protocol on port 143 for unencrypted communication and port 993 for the SSL version.

In order to not receive an SSL certificate warning when using the SSL version, you must use our servername , imap.emailarray.com ,in your e-mail client configuration
