==Introductions and Apologies==

VISTA Mailman is standards compliant email server; it can send and receive emails. However, it does not comply with the newer standards (e.g. ESMTP).
 +
 +
Before you start doing anything, you need to make sure that Taskman is running and that the VISTA Background Mail Filer is running. I won't show you how to start Taskman (way way off topic), but I will show up how to check the filer.

First you need to set-up an Email Server that accepts unauthenticated email via SMTP and relays it to the outside world. If you have an old style smtp relay server from your ISP, that will suffice. If you, like me, have a server that will only accept TLS encyrpted and Authenticated SMTP, you can't send email directly from VISTA. Instead, you need to send it to a relay that will forward your email. I have had pretty good luck with postfix.
 +
 
 +
I saw this article for setting up Postfix as a relay server for email; and that's what I used to get postfix to authenticate against my company's smtp server that uses STARTTLS. http://www.marksanborn.net/linux/send-mail-postfix-through-gmails-smtp-on-a-ubuntu-lts-server/
 +
 
 +
Before, doing anything with VISTA, make sure you can send emails from the VISTA machine using roll and scroll. Easiest way is to telnet into your mail server smtp port and send a message using SMTP (vide http://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol).
 +
 
 +
Here's an example:
 +
 
 +
<pre style="padding:1em;border:1px dashed #2f6fab;color:black;background-color:#f9f9f9;line-height:1.1em">
 +
sam@sam-desktop:~/pocn-moh$ telnet localhost 10025
 +
Trying ::1...
 +
Trying 127.0.0.1...
 +
Connected to localhost.
 +
Escape character is '^]'.
 +

 +

 +

 +

 +

 +

 +

 +

 +
 
 +

 +

 +

 +

 +
</pre>
 +
 
 +
Now you would check your email to see if you have gotten any mail. If you did, we are in business.
 +
 
 +
If you have an unauthenticated SMTP, make an new entry in the Domain file like this, assuming that your SMTP is smtp.example.com.
 +
 
 +
<pre style="padding:1em;border:1px dashed #2f6fab;color:black;background-color:#f9f9f9;line-height:1.1em">

These synonyms turn out to be important. VISTA will look for the email domain suffix, and match it against a domain. By default, VISTA will send email to your parent domain if it can't match the domain suffix.
 +
 
 +
Now, what if you don't have an unencrypted unauthenticated SMTP server to send to? Well, in that case, you need to send your emails to a relay mail agent who logs in and encrypts data on your behalf.
 +
 
 +
In that case, your domain will look like this (I setup postfix on my localhost, so postfix is located at 127.0.0.1. If your postfix or other relay server is else where, put the correct ip address).
 +

While you can expose your VISTA system to the outside world, it is better to have email go through your own mail server and then be relayed to VISTA. Either way, the VISTA set-up is the same.

I have a domain name that is linked to my ip address through dynamic DNS. So I opened port 25 on my router and had it forwarded to the machine hosting VISTA on port 25 on the machine. So if I send email to my domain from Gmail, it reaches VISTA.
  
 
Set-up a xinetd listener to forward requests on port 25 (or another port, if you are forwarding email to VISTA from a mail server) to a script that sets up GT.M and calls <code>GTMLNX^XMRUCX</code>.

Now, to actually send an email message. First, find a real email address in VISTA. I do that by going to my Mailman account on VISTA and see what my address is.

Good. So now we have it. Bear in mind though that in real life, you need to tell email coming from Google or Yahoo that @EXAMPLE.COM needs to go to a specific IP address through an MX Domain [[Record~|Record]]. Also, you need to tell VISTA that its Domain is EXAMPLE.COM so it receives the messages instead of tossing them away.

Introductions and Apologies

VISTA Mailman is standards compliant email server; it can send and receive emails. However, it does not comply with the newer standards (e.g. ESMTP).

Before you start doing anything, you need to make sure that Taskman is running and that the VISTA Background Mail Filer is running. I won't show you how to start Taskman (way way off topic), but I will show up how to check the filer.

Sending

Most people want to send email to the outside world from VISTA. So we will start with that.

First you need to set-up an Email Server that accepts unauthenticated email via SMTP and relays it to the outside world. If you have an old style smtp relay server from your ISP, that will suffice. If you, like me, have a server that will only accept TLS encyrpted and Authenticated SMTP, you can't send email directly from VISTA. Instead, you need to send it to a relay that will forward your email. I have had pretty good luck with postfix.

I saw this article for setting up Postfix as a relay server for email; and that's what I used to get postfix to authenticate against my company's smtp server that uses STARTTLS. http://www.marksanborn.net/linux/send-mail-postfix-through-gmails-smtp-on-a-ubuntu-lts-server/

Before, doing anything with VISTA, make sure you can send emails from the VISTA machine using roll and scroll. Easiest way is to telnet into your mail server smtp port and send a message using SMTP (vide http://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol).

Here's an example: 

sam@sam-desktop:~/pocn-moh$ telnet localhost 10025
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 sam-desktop ESMTP Postfix (Ubuntu)
HELO relay.example.org
250 sam-desktop
MAIL FROM:<sam@example.org>
250 2.1.0 Ok
RCPT TO:<sam@example.org>
250 2.1.5 Ok
DATA
354 End data with <CR><LF>.<CR><LF>
From: "Bob Example" <bob@example.org>
To: "Alice Example" <alice@example.com>
Date: Tue, 15 Jan 2008 16:02:43 -0500
Subject: Test message

Hello Alice. Bye Alice.
.
250 2.0.0 Ok: queued as 62184840557
QUIT
221 2.0.0 Bye
Connection closed by foreign host.

Now you would check your email to see if you have gotten any mail. If you did, we are in business.

If you have an unauthenticated SMTP, make an new entry in the Domain file like this, assuming that your SMTP is smtp.example.com. 

NAME: smtp.example.com                  FLAGS: S
  MAILMAN HOST: smtp.example.com        DISABLE TURN COMMAND: YES
TRANSMISSION SCRIPT: TOMYSMTP           PRIORITY: 1
  NUMBER OF ATTEMPTS: 4                 TYPE: TCP/IP Channel
  PHYSICAL LINK / DEVICE: NULL
  NETWORK ADDRESS (MAILMAN HOST): smtp.example.com
 TEXT:
 O H="smtp.example.com",P=TCP/GTM
 C TCPCHAN-SOCKET25/GTM
SYNONYM: NET
SYNONYM: COM
SYNONYM: ORG
SYNONYM: JO

These synonyms turn out to be important. VISTA will look for the email domain suffix, and match it against a domain. By default, VISTA will send email to your parent domain if it can't match the domain suffix.

Now, what if you don't have an unencrypted unauthenticated SMTP server to send to? Well, in that case, you need to send your emails to a relay mail agent who logs in and encrypts data on your behalf.

In that case, your domain will look like this (I setup postfix on my localhost, so postfix is located at 127.0.0.1. If your postfix or other relay server is else where, put the correct ip address). 

NAME: 127.0.0.1                         FLAGS: S
  MAILMAN HOST: 127.0.0.1               DISABLE TURN COMMAND: YES
TRANSMISSION SCRIPT: TOGMAIL            PRIORITY: 1
  NUMBER OF ATTEMPTS: 4                 TYPE: TCP/IP Channel
  PHYSICAL LINK / DEVICE: NULL
  NETWORK ADDRESS (MAILMAN HOST): 127.0.0.1
 TEXT:
 O H="127.0.0.1",P=TCP/GTM
 C TCPCHAN-SOCKET25/GTM
SYNONYM: NET
SYNONYM: COM
SYNONYM: ORG
SYNONYM: JO

You have to try to see if your settings have worked:

We can see that the script played a complete smtp send. So we know stuff worked.

Turn your background filer on and enjoy sending emails from VISTA!

Receiving

While you can expose your VISTA system to the outside world, it is better to have email go through your own mail server and then be relayed to VISTA. Either way, the VISTA set-up is the same.

I have a domain name that is linked to my ip address through dynamic DNS. So I opened port 25 on my router and had it forwarded to the machine hosting VISTA on port 25 on the machine. So if I send email to my domain from Gmail, it reaches VISTA.

Set-up a xinetd listener to forward requests on port 25 (or another port, if you are forwarding email to VISTA from a mail server) to a script that sets up GT.M and calls GTMLNX^XMRUCX. 

sudo cat vista_pocn-moh_mm_port25
service vista-mm
        {
        disable = no
        port = 25
        socket_type = stream
        protocol = tcp
        user = sam
        server = /bin/bash
        groups = yes
        server_args = /home/sam/pocn-moh/mm_rpcproc
        type = UNLISTED
        wait = no
        }

sam@sam-desktop:~/pocn-moh$ cat mm_rpcproc
#!/bin/bash
#
cd /home/sam/pocn-moh
export gtm_dist=/opt/fis-gtm/V5.4-002A/utf8/
export gtmroutines="uo(routines) $gtm_dist"
export gtmgbldir=mumps.gld
export PATH=$PATH:$gtm_dist
export gtm_chset=utf-8
export gtm_icu_version=4.2
export gtm_badchar=0
date>>rpc_log.log
$gtm_dist/mumps -run GTMLNX^XMRUCX 2>> rpc_log.log
exit 0

Stop xinetd and start it in debug mode: 

sam@sam-desktop:/etc/xinetd.d$ sudo service xinetd stop

Make sure you see this line to indicate that your service started.

Check netstat -tnlp to see that your port is open.

Now, to actually send an email message. First, find a real email address in VISTA. I do that by going to my Mailman account on VISTA and see what my address is.

So my email address is HABIEL.SAM_M@MOH.AMMAN.JO. Nice. Let's see if I can send myself an email. Text in bold are my commands to VISTA.

You should see this in xinetd:

11/5/18@13:17:27: DEBUG: 6623 {main_loop} active_services = 7

Here's the message in VISTA:

Good. So now we have it. Bear in mind though that in real life, you need to tell email coming from Google or Yahoo that @EXAMPLE.COM needs to go to a specific IP address through an MX Domain Record. Also, you need to tell VISTA that its Domain is EXAMPLE.COM so it receives the messages instead of tossing them away.
