ETRN Last modified: Friday, May 16, 2003
Short for Extended Turn, an extension to the SMTP mail delivery protocol that allows an SMTP server to request from another SMTP server any e-mail messages it has for a specific domain. ETRN typically is used to retrieve e-mail messages from a mail server that does not have a dedicated connection to the Internet. ETRN can only be used in conjunction with an ISP that supports ETRN.
RFC 1985 This RFC explains the details of ETRN.	Related Categories Electronic Mail Internet Protocols Related Terms e-mail IMAP ISP ODMR POP SMTP
