IMAP by Zapier – retrieving emails from mail servers
Wikipedia (https://en.wikipedia.org/wiki/Internet_Message_Access_Protocol) defines Internet Message Access Protocol (IMAP) as "an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection." IMAP allows email client apps to retrieve emails from the server. If you are using an email server other than Gmail, Zoho Mail, or Microsoft Office 365, you can use IMAP by Zapier to retrieve emails from these mail servers. For example, these servers may include Rackspace, Zimbra, or Microsoft Exchange Server.
The following figure shows a list of a few common IMAP settings that will be useful when you set up your IMAP by Zapier app:
