It is best practice to route emails through an existing exchange server or a 3rd party mail server. However, you can route messages via the SMTP SIGNL4 server, i.e. connect your SMTP email client directly with the SIGNL4 mail server. This is called direct SMTP.
Server Details and supported methods:
mail.signl4.com
Port 25 - Unsecured transmission and optionally STARTTLS to switch to a secured connection
Port 587 - Unsecured transmission and optionally STARTTLS to switch to a secured connection
Port 465 - TLS only (and command sent via an unsecured connection results in an error)
You can send plain text emails and HTML emails. Image and sound attachments are also supported and will be displayed in the app. Example scenarios are after hour voice box notifications.
To parameterize your Signls, use the "parameter: value" schema. Below is an example:
Title: Critical problem
Message: Database system XA4 reported error 49918.
Severity: 16
X-S4-Service: Database
Here are some additional info on secure ports:
Port 465 is for SMTPS
SSL encryption is started automatically before any SMTP level communication.
Port 587 is for MSA
It is almost like standard SMTP port. MSA should accept email after authentication (e.g. after SMTP AUTH). It helps to stop outgoing spam when netmasters of DUL ranges can block outgoing connections to SMTP port (port 25).
SSL encryption may be started by STARTTLS command at SMTP level.
