SMTPtg
Forked from simplylizz/smtp_to_telegram package.
smtptg is a small program which listens for SMTP and sends
all incoming Email messages to Telegram.
Say you have a software which can send Email notifications via SMTP.
You may use smtptg as an SMTP server so
the notification mail would be sent to the chosen Telegram chats.
Getting started
Run:
docker run --rm -p 25:25 -e ST_TELEGRAM_BOT_TOKEN=XXXXXXXXXXX -e ST_TELEGRAM_CHAT_IDS=XXXXXXXXX ghcr.io/muratovas/smtptg:latest
Request to check the service:
curl \
--url 'smtp://localhost:25' \
--mail-from sender@test.test \
--mail-rcpt user@test.test --mail-rcpt user1@test.test \
-H "Subject: Test smtptg" -F '=(;type=multipart/mixed' -F "=This message came via smtp;type=text/plain" -F '=)'
Sending personal messages is supported. Instead of email, enter an entry like 000000000@telegram.org. Where 000000000 is chat id.
Classic emails will still be sent to the ID specified in ST_TELEGRAM_CHAT_IDS.
Options
A custom format might be specified as well:
ST_TELEGRAM_BOT_TOKEN=<BOT_TOKEN>
ST_TELEGRAM_CHAT_IDS=<CHAT_ID1>,<CHAT_ID2> # optional
ST_TELEGRAM_MESSAGE_TEMPLATE="Subject: {subject}\\n\\n{body}" # optional
ST_SMTP_ALLOWED_HOSTS=cvzilla.net,example.com # optional
The default Telegram message format is:
From: {from}\\nTo: {to}\\nSubject: {subject}\\n\\n{body}\\n\\n{attachments_details}
