SMTP

Send notifications via SMTP (email and SMS)

Simple Mail Transfer Protocol (SMTP) is a protocol to send and relay emails. In addition it can be used as a tool to send SMS messages via email (i.e. email -> phone) as well — though see the important caveat under Sending SMS messages before relying on that path.

This document describes how to initiate the SMTP service on AnyLog and how to use it.

Setting up SMTP

Enables email and SMS notifications triggered by the scheduler or rule engine. See Alerts and Monitoring for how to configure notification rules.

run smtp client where
  host = [host] and port = [port] and
  email = [address] and password = [password] and
  ssl = [true/false]
Option Description Default
host SMTP server URL smtp.gmail.com
port SMTP server port  
email Sender email address  
password Sender email password  
ssl Use secure SMTP connection false

Example:

run smtp client where email = anylog.iot@gmail.com and password = [password]

Sending a message

To facilitate messages, declare the SMTP client process. Details are available at Background Processes (see the Services overview table — run smtp client).

Sending an email

Usage:

email to [receiver email] where subject = [message subject] and message = [message text]

Command Options:

Option Explanation Default
receiver email The destination address  
message subject Any text AnyLog Alert
message text Any text AnyLog Network Alert from Node: [node name]

Example:

email to my_name@my_company.com

Multiple message texts on the command line, like the example below, will be represented as multiple lines in the email message:

email to my_name@my_company.com  where subject = "anylog alert" and message = "Value of Heater sensor is above threshold" and message = "Reporting node: 24.23.250.144 (Operator SF)"

Sending SMS messages

Important — carrier gateways are largely deprecated as of 2026. The sms to command below works by emailing a carrier’s free “email-to-SMS” gateway address (e.g. [number]@txt.att.net), a mechanism most major US carriers have now shut down or are actively winding down due to spam abuse. Before depending on this for anything operationally important (alerting, monitoring, incident response), see the status table below and consider using the rest post based notification pattern documented in Notification Services instead (Telegram, Pushover, Slack, or a dedicated SMS API such as Twilio) — those go through a real, maintained API rather than a side-channel carriers are actively closing.

Usage:

sms to [receiver phone] where gateway = [sms gateway] and subject = [message subject] and message = [message text]

Command Options:

Option Explanation Default
receiver phone The destination phone number  
gateway The SMS carrier gateway  
message subject Any text AnyLog Alert
message text Any text AnyLog Network Alert from Node: [node name]

Example with T-Mobile as a carrier (see status note below — this gateway no longer works):

sms to 4155550123 where gateway = tmomail.net

Carrier gateway status (as of 2026)

Gateway addresses for the major USA carriers, along with their current known status. Verify independently before depending on any of these — this space has been changing quickly and carriers have shut gateways down with no notice.

Carrier Gateway Status (2026)
AT&T txt.att.net Dead — shut down June 17, 2025
Sprint messaging.sprintpcs.com Dead — shut down 2022; carrier absorbed into T-Mobile
T-Mobile tmomail.net Dead — stopped working by December 2024
Verizon vtext.com Degrading — increasingly unreliable, full shutdown announced for March 2027
Boost Mobile myboostmobile.com Dead — no longer delivering
Metro PCS mymetropcs.com Likely dead — Metro PCS has been a T-Mobile-owned brand since 2013
Tracfone mmst5.tracfone.com Unreliable — rides on whichever underlying network (AT&T/T-Mobile/Verizon) the plan uses
U.S. Cellular email.uscc.net Reportedly still working, but U.S. Cellular’s wireless business was acquired by T-Mobile in August 2025 — treat as at-risk
Virgin Mobile vmobl.com Dead — Virgin Mobile USA is defunct; folded into Boost, whose new owner (Dish) shut the gateway down
