The ETRN command is an SMTP extension that signals a server storing mail for a particular domain that it is time to begin spooling the mail. When MDaemon receives an ETRN request for a domain, it will immediately begin spooling the stored mail for delivery using subsequent SMTP transactions. Please note that the SMTP session that issues an ETRN request will not be the one that receives any stored mail. MDaemon will use subsequent independent SMTP transactions to send any mail it has stored for the domain. This preserves the message envelope and is more secure. Also note that the host to which MDaemon will spool any stored mail may not immediately begin reception of these messages. ETRN only guarantees that any stored mail is <\/span><span style=\"font-family: Arial,Helvetica,sans-serif; font-style: italic; color: #010100;\">spooled <\/span><span class=\"f_ControlIndent\">for delivery. The actual <\/span><span style=\"font-family: Arial,Helvetica,sans-serif; font-style: italic; color: #010100;\">process<\/span><span class=\"f_ControlIndent\"> of delivery is subject to other administrator-imposed restrictions and may have to wait in the outbound mail queue for the next scheduled remote mail processing event to take place. Because of these limitations we recommend using <a href=\"mail-release_odmr.html\" class=\"topiclink\">On-Demand Mail Relay (ODMR)<\/a> and its ATRN command rather than ETRN. This method is not supported by all clients and servers, however, and will therefore only be available to client domains using a server that does so. MDaemon fully supports ODMR on both the client and server side.<\/span><\/p>\n\r<div style=\"text-align: left; text-indent: 0; padding: 0 0 0 0; margin: 0 3.0625rem 0.8750rem 3.0000rem;\"><table style=\"background-color:#ffffe6; border:solid thin #000000; border-spacing:0;\">\n\r<tr>\n\r<td style=\"vertical-align:top; width:3.1250rem; height:3.1250rem; padding:0.3125rem; border:none\"><p class=\"p_NoFormat\"><img style=\"margin:0;width:3.1250rem;height:3.1250rem;border:none\" src=\".\/images\/lightbulb_on_50_yback.gif\"\/><\/p>\n\r<\/td>\n\r<td style=\"vertical-align:top; padding:0.3125rem; border:none\"><p class=\"p_Notes\"><span class=\"f_Notes\">By default MDaemon requires that the connecting host issuing the ETRN request first authenticate itself via ESMTP AUTH using the <\/span><span class=\"f_Notes\" style=\"font-style: italic;\"><a href=\"gateway_gateway.html\" class=\"topiclink\">Domain name<\/a><\/span><span class=\"f_Notes\"> and Gateway <\/span><span class=\"f_Notes\" style=\"font-style: italic;\">ATRN password<\/span><span class=\"f_Notes\"> as its login credentials.

It is superior to ETRN and other methods in that in requires authentication before mail is dequeued and does not require a static IP address. A static IP address isn\'t required because the flow of data between MDaemon and the client domain is immediately reversed and the messages are de-spooled without having to make a new connection, unlike <\/span><span style=\"font-family: \'Courier New\',Courier,monospace; color: #010100;\">ETRN<\/span><span class=\"f_ControlIndent\">, which uses a separate connection after the <\/span><span style=\"font-family: \'Courier New\',Courier,monospace; color: #010100;\">ETRN<\/span><span class=\"f_ControlIndent\"> command is sent. This enables client domains with a dynamic (non-static) IP address to collect their messages without having to use POP3 or DomainPOP, because the original SMTP envelope is preserved.<\/span><\/p>\n\r<div style=\"text-align: left; text-indent: 0; padding: 0 0 0 0; margin: 0 3.0625rem 0.8750rem 3.0000rem;\"><table style=\"background-color:#ffffe6; border:solid thin #000000; border-spacing:0;\">\n\r<tr>\n\r<td style=\"vertical-align:top; width:3.1250rem; height:3.1250rem; padding:0.3125rem; border:none\"><p class=\"p_NoFormat\"><img style=\"margin:0;width:3.1250rem;height:3.1250rem;border:none\" src=\".\/images\/lightbulb_on_50_yback.gif\"\/><\/p>\n\r<\/td>\n\r<td style=\"vertical-align:top; padding:0.3125rem; border:none\"><p class=\"p_Notes\"><span class=\"f_Notes\">ATRN requires a session using the AUTH command.
