To complete the integration, you will need to set up the PowerMTA account file configuration and Logstash installation on the pmta server. We recommend version Logstash 8.17.0 or higher.
Supported Versions: PowerMTA™ v5.0r3 and above
Using your favorite editor open the configuration file located at /etc/pmta/config.
To allow EmailElement to send emails using your MTA, our IPs will need to be added as a source.
To accomplish this, please add the following IPs: 38.74.128.59, 64.62.168.6 and, 8.45.58.31 as sources:
<source 38.74.128.59>
always-allow-relaying yes # allow feeding from emailelement ip 38.74.128.59
process-x-virtual-mta yes # allow selection of virtual MTA
max-message-size unlimited
smtp-service yes # allow SMTP service
</source>
<source 64.62.168.6>
always-allow-relaying yes # allow feeding from emailelement ip 64.62.168.6
process-x-virtual-mta yes # allow selection of virtual MTA
max-message-size unlimited
smtp-service yes # allow SMTP service
</source>
<source 8.45.58.31>
always-allow-relaying yes # allow feeding from emailelement ip 8.45.58.31
process-x-virtual-mta yes # allow selection of virtual MTA
max-message-size unlimited
smtp-service yes # allow SMTP service
</source>
In order for EmailElement to track your deliveries, we will need to receive delivery events from your MTA.
To accomplish this, we will output the content a log file using the account files:
<acct-file /var/log/pmta/eelog.csv>
records b,d,t
record-fields b timeLogged,rcpt,dlvSourceIp,dlvDestinationIp,header_Message-Id,dsnDiag,bounceCat,timeQueued,orig
record-fields d timeLogged,rcpt,dlvSourceIp,dlvDestinationIp,header_Message-Id,dsnDiag,bounceCat,timeQueued,orig
record-fields t timeLogged,rcpt,dlvSourceIp,dlvDestinationIp,header_Message-Id,dsnDiag,bounceCat,timeQueued,orig
move-interval 2m
max-size 2M
world-readable true
</acct-file>
Next, we need to install Logstash to send the log file content's to EmailElement's webhook.
