Signal remote host to release waiting mail
When it is time to process remote mail MDaemon can connect to any server on any port and send any string that you wish to send. This is useful when you need to signal a remote server to release your mail by sending some string to them. For example, ATRN, ETRN, or QSND. You can also use this feature when a FINGER or TELNET session is briefly required in order for your remote host or ISP to determine that you are online.
Host name or IP
This is the host that will be signaled to release your mail.
Port
Enter the port on which you wish to make the connection. The default is 25 (the SMTP port), which is appropriate for the ETRN or QSND signaling method. Port 366 is typically used for ATRN, and port 79 is used for FINGER.
Send this string of text to host (leave blank if merely connecting is enough)
This control is for specifying the text string that needs to be sent in order for your mail to be released. For example, the ETRN method requires the text "ETRN" followed by the domain name of the site being queued. Other methods require different text to be sent. Consult your ISP if you need more information on what to send to unlock your mail queue. If you have a choice of the method to use, we recommend using On-Domain Mail Relay (ODMR) whenever possible. ODMR requires the ATRN command to be used in this option.
Send signal once every [xx] times remote mail is processed (0=every time)
By default the dequeue signal will be sent each time that remote mail is processed. Entering a number into this control will prevent the dequeue signal from being sent every time. It will be sent every x number of times as designated. For example, setting this value to "3" would cause the signal to be sent every third time that remote mail is processed.
Send "EHLO" before sending the text string
If you enable this checkbox then you should be connecting to an SMTP server to signal release of your mail. This switch causes an SMTP session to be initiated with the specified host and allows the session to progress just beyond the SMTP "EHLO" stage before sending the unlock string.
Authenticate before sending the text string (required for ATRN)
As a security measure, some hosts or servers require clients to authenticate using ESMTP AUTH before releasing waiting messages. If this is the case for your mail host, click this checkbox and enter the required authentication credentials below.

Password

On-Demand Mail Relay (ODMR)
When you require a queue/dequeue method for hosting and releasing your email, we recommend using On-Demand Mail Relay (ODMR) whenever possible. This method is superior to ETRN and other methods in that in requires authentication before mail is released. Further, it utilizes an ESMTP command called ATRN that does not require the client to have a static IP address, because it immediately reverses the flow of data between the client and server, releasing the messages without having to make a new connection to do so (unlike ETRN).
MDaemon fully supports ODMR on the client side via using the ATRN command and authentication controls on the Mail Release screen, and on the server side using the Domain Gateways features on the Dequeuing screen of the Gateway Editor.
Some mail servers do not support ODMR, therefore you should check with your provider before attempting to use it.
