Question
In linux, SMTP protocal is used by mail client to send outgoing mail to target server, while IMAP/POP3 is used by mail client to reteive incoming emails from server. What is main difference between IMAP vs POP3?
Answer
IMAP (Internet Message Access Protocal) is newer and with this protocal email is kept on the server (until explicitly deleted) so it is ideal for retreiving email on multiple devies (PC, mobile, etc). While POP3 (Post Office Protocal 3) is older and with this protocal email is downloaded from server by first device that accesses it, and thereafter automatically deleted (so not ideal for retreiving email on multiple devices).
