Email

The Email operators can automate tasks that are performed on messages and folders in an email server. Email operators communicate with your mail server remotely using one of the following protocols:

Post Office Protocol version 3 (POP3)

POP3, suitable for single-user access to a mailbox, allows you to download email messages to your local computer. By default, POP3 servers listen on TCP Port 110.

POP-SSL

By default, POP-SSL servers listen on TCP Port 995.

Internet Message Access Protocol (IMAP)

IMAP, suitable for multi-user access to a mailbox, allows simultaneous access by multiple clients. By default, IMAP servers listen on TCP Port 143.

IMAP-SSL

By default, IMAP-SSL servers listen on TCP Port 993.

The Email operators can communicate with your mail server only if it supports either IMAP or POP3. The Email operators perform actions such as get email counts. Both protocols support this type of action. Some actions, such as delete folder, are supported only by the IMAP protocol.
