mpsn Posted February 26, 2012 Share Posted February 26, 2012 Hi, I would just like to clarify: SMTP is currently the only outgoing mail server (so when an email client like GMail or Outlook Express where user sends an email) Then on recipient end, that person uses either POP3 or IMAP to retrieve the message from the email server that was sent and stored by SMTP protocol. And IMAP is better than POP3 b/c it keeps your email in your server even after user deletes from inbox in their email client. Is that right?

requinix Posted February 26, 2012 Share Posted February 26, 2012 Not really. SMTP is a protocol for moving emails between servers. Programs use this protocol to send (and thus receive) email. There are many programs that handle either/both sides of that transaction. POP3 and IMAP are protocols for accessing stored emails. Both allow for retrieving email without deleting, both can keep or delete emails after the user has "deleted" them. IMAP is "better" because it has more features and fewer limitations.
