POP3 (Post Office Protocol 3.0) is the traditional protocol for fetching e-mail from an Internet mail server.
POP3 (Post Office Protocol 3.0) is the traditional protocol for fetching e-mail from an Internet mail server. Any e-mail client (any e-mail program you use) should work with a standards-compliant POP3 mailserver. The EServer fully supports POP3 e-mail accounts for its members, level 3 and above.
If you have an EServer e-mail account, set your favorite e-mail client to use "eserver.org" as its POP3 server. You can use your own Internet service provider's SMTP server for outgoing mail, or can use eserver.org if you provide APOP or SSL authentication; the EServer won't serve outgoing mail unless you provide your username and password to establish you're a senior EServer member (in order to prevent spam relaying).
POP3 has largely been replaced by a newer protocol, one with many newer features, called IMAP4. Newer e-mail clients support IMAP servers, which tend to be somewhat faster and easier to use from multiple computers. (There's no actualy difference in the sort of e-mail messages sent or received--those are all the same from either protocol.) The EServer supports both standards; if you have an e-mail client that supports IMAP, you'll probably prefer to set your e-mail client to use IMAP instead (again, set your client to use "eserver.org"). Our webmail software is open to EServer members who have EServer e-mail accounts, is based upon IMAP.
