IMAP (Internet Message Access Protocol) and POP (Post Office Protocol) are the two most prevailing methods or protocols for retrieving email from a mail server. Both of these protocols are supported by almost all popular mail client programs like Outlook, Thunderbird and Apple Mail. Similarly, Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (email) transmission. However, Simple Network Management Protocol (SNMP) is an “Internet-standard protocol for managing devices on IP networks”. Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and more. SNMP is widely used in network management systems to monitor networkattached devices for conditions that warrant administrative attention.
