Outbox Properties

Options | Outgoing Mail

Remote Mail Server Tab
This tab appears on the Outbox Properties dialog and is used to describe the remote and backup mail servers to which outbound mail is delivered by default if Static Routing Table rules have not been configured or if the mail cannot be delivered to the mail host(s) specified in those routes.

Local users
Messages to local users (mailboxes created on your Mailtraq) are routed direct to the user's mailbox. They do not pass through the Outbox.

Mailtraq uses the Domain and Domain Alias settings at Options | Server to determine which domains are local, so it is important that correctly reflects your domain.
Messages that are determined as local but for which there is no user-mailbox will follow the Undelivered mail rule.

Default setting
Mailtraq will send outgoing messages by direct delivery using MX Resolution on Port 25 direct to the recipient's mail server. This is the most efficient and secure way to send email messages. No additional configuration is required.

To another mail server (SmartHost)
Some ISPs limit the use of Port 25 to prevent MX Resolution on some types of account  - in which case Mailtraq allows you to send mail to your ISP's mail server - also known as its 'SmartHost' - on the Port, sometimes 587, they specify. See Configuration Tip below.

Custom Routes
Mailtraq also allows you to configure Custom Routes, so that you can send some messages via one route and other messages via another.



Option 1 - Deliver all mail to these Smart Hosts

Primary Mail Server
Enter the host name of the remote mail server into the edit box, for example:  The correct value for this service is provided by your ISP.  An IP address may be specified instead of a host name but it is not usual practice. 

You may also be able to use Gmail as your Smart Host...

You may enter the IP address of the remote mail server. (e.g.

Mailtraq will attempt connections to remote mail servers on port 25 by default. 

If you have a working email account with an ISP for your email client (e.g. Outlook)
use the same SMTP settings here.

If another port must be used then you should enter that port number in the box provided.
(For older dialog see below).

Backup Mail Server
Enter the name of the backup mail server into the edit box.  Note: The backup mail server has the same requirements as the Primary Domain Server defined above.

SMTP Authentication & SSL or TLS Connection
 If your ISP also requires Authentication you can add the username and password, and select SSL/TLS at the small  padlock symbol. Read more ...

Option 2 - Use MX Resolution using the DNS servers below

This is the Default Option.
MX Resolution is used to deliver mail to the most appropriate mail server for any given recipient. Mailtraq queries your DNS servers to determine the location of the recipient's mail
server by 'looking up' (resolving) their MX records. 

The DNS server(s) listed are automatically detected by the mail server from the DNS server entered in the machine's NIC (network card).

Custom DNS Servers
You may specify different DNS servers by selecting the DNS-icon which will open the
 Options | Server | Lan-tab dialog (as shown).
Changes are set next time Mailtraq starts.

Which DNS servers should I use?
You can use Google's Public DNS servers, the ones recommended by your ISP or choose your own. These free software packages: DNS Benchmark  or  Namebench - can analyze the best DNS responding servers for your location.

Mail doesn't get delivered - how do I solve this?
Solving outgoing mail problems is explained in this FAQ - Mail will not send out.

Option 3 - Use Custom Routing Table

This option allows the user to define the static route the outgoing mail should take.  Options include defining Static Routing Table, Dynamic Routing Table and the Domain Name Cache. Multiple routes can be created. Read about Custom Routing Table here ...


Working with older Mailtraq consoles


Older Mailtraq consoles do not allow direct entry of non-standard ports. 
All non standard configuration must be done using a Custom Route.

Some ISPs require you to use a 'secure' or 'non-standard' port when using their smarthost: Port 587 is common. As you cannot enter a specific port into the simple dialog box shown above - you need to use the Custom Routing Table which gives you advanced control over how mail is sent.
Use of the Custom Routing Table is explained more fully here:  Custom Routing Table

Below are the simple setting adjustments you will need to make to set a specific port for the SMTP smarthost.

[x] Use Custom Routing Table, then click [Edit Table]

At the Table create a route

Click on Add
Select the new default entry in the list box
Enter the required route details:

Address Spec: * (enter a single asterisk: ALT+0042)
Mail Hosts:

  If your ISP also requires Authentication you can add the username and password at the small  padlock symbol.

Position the new entry (if there are existing entries in the list box) by clicking repeatedly on Move Up or Move Down as required. 
and [OK] back to the Console.

The route will become active when the Outbound Router becomes idle.
