Experimental Winlink RMS Relay

The experimental Winlink RMS Relay serves as a Network Post Office (NPO) speaking the Winlink protocols.  It allows users to send ham radio e-mail messages to one another within our mesh, using the Winlink Express messaging application.  It's also possible to use a regular e-mail client such as Outlook, Thunderbird, Pine, etc., using the SMTP, POP3, and IMAP protocols.

To connect to the RMS Gateway using Winlink Express, open a new Telnet Winlink session and click Settings.  Configure the Telnet Properties dialog as shown below:

  • Use RMS Relay:  Yes
  • TCP/IP path to the RMS Relay site:  W4RAT-VPM-GW
  • Port to connect to:  8772
  • Connect to RMS Relay local message database rather than a CMS:  No
  • Telnet Session AutoConnect Time:  (as desired)
  • Automatic Background Monitoring and Message Uploading:  (as desired)

Click the Start Button.  You should notice the telnet session is with W4RAT-VPM-GW.  You are now communicating with the RMS-Relay and can begin sending and receiving messages from other users on our AREDN system.  The mail system supports local messages with attachments up to 5 megabytes in size.


Connectivity to the rest of the Winlink network is a planned future enhancement.

To return to normal Winlink CMS telnet function, return to the Telnet Properties dialog and un-check the "Use RMS Relay" box.

SMTP, IMAP, POP3 and Webmail access to the Winlink NPO

To request access via SMTP, IMAP, and POP3, send an e-mail to techcomm-chair@rats.net and allow up to 7 days for provisioning.  Once configured, use the following servers:

  • Outgoing mail server:  W4RAT-VPM-GW, SMTP port 25
  • Incoming mail server:  W4RAT-VPM-GW, POP3 port 110 or IMAP port 143

Once enabled for SMTP, IMAP, and POP3 service, you may access the Winlink NPO through an experimental webmail interface at http://kg4peq-gw/webmail using the credentials issued by RATS.

Network Time Services

There are now two ways to obtain a reasonably accurate time using standard Network Time Protocol (NTP) on UDP port 123:

Server
Time Source
W4RAT-VPM-GW.local.mesh
w32tm - Win32 ntpd running on-site.  Dependent on system clock.  Host PC syncs w/NTP pool via WAN.
KG4PEQ-GW.local.mesh
Direct forward to time.nist.gov via WAN

Ideally, a GPS-based time source will eventually be deployed on the mesh.
