Configure delivery settings delivery-settings

The delivery parameters must be configured in the serverConf.xml folder.

  • DNS configuration: specify the delivery domain and the IP addresses (or host) of the DNS servers used to respond to MX-type DNS queries made by the MTA module from the <dnsconfig> onwards.

    note note
    The nameServers parameter is essential for an installation in Windows. For an installation in Linux, it must be left empty.
    code language-none
    <dnsConfig localDomain="domain.com" nameServers=","/>

You can also carry out the following configurations depending on your needs and settings: configure a SMTP relay, adapt the number of MTA child processes, Manage outbound SMTP traffic.

SMTP relay smtp-relay

The MTA module acts as a native mail transfer agent for SMTP broadcast (port 25).

It is, however, possible to replace it by a relay server if your security policy requires it. In that case, the global throughput will be the relay one (provided that the relay server throughput is inferior to the Adobe Campaign one).

In this case, these parameters are set by configuring the SMTP server in the <relay> section. You must specify the IP address (or host) of the SMTP server used to transfer mail and its associated port (25 by default).

<relay address="" port="25"/>
This operating mode implies serious limitations on deliveries, as it can greatly reduce the throughput because of the relay server intrinsic performances (latency, bandwidth…). Moreover, the capacity to qualify synchronous delivery errors (detected by analyzing SMTP traffic) will be limited, and the sending will not be possible if the relay server is not available.

MTA child processes mta-child-processes

It is possible to control the number of child processes (maxSpareServers by default 2) in order to optimize broadcast performance according to the CPU power of the servers and the available network resources. This configuration is to be made in the <master> section of MTA configuration on each individual computer.

<master dataBasePoolPeriodSec="30" dataBaseRetryDelaySec="60" maxSpareServers="2" minSpareServers="0" startSpareServers="0">

Manage outbound SMTP traffic with affinities managing-outbound-smtp-traffic-with-affinities

The affinity configuration needs to be consistent from one server to another. We recommend that you contact Adobe for affinity configuration, as configuration changes should be replicated on all application servers running the MTA.

You can improve outbound SMTP traffic through affinities with IP addresses.

To do this, apply the following steps:

  1. Enter the affinities in the <ipaffinity> section of the serverConf.xml file.

    One affinity can have several different names: to separate them, use the ; character.


    code language-none
     IPAffinity name="mid.Server;WWserver;local.Server">
              <IP address="XX.XXX.XX.XX" heloHost="myserver.us.campaign.net" publicId="123" excludeDomains="neo.*" weight="5"/

    To view the relevant parameters, refer to the serverConf.xml file.

  2. To enable affinity selection in the drop-down lists, you need to add the affinity name(s) in the IPAffinity enumeration.

    note note
    Enumerations are detailed in this document.

    You can then select the affinity to be used, as shown below for typologies:
