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.
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 000000000@telegram.org \
-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.
A custom format might be specified as well:
ST_TELEGRAM_BOT_TOKEN=<BOT_TOKEN>
ST_TELEGRAM_CHAT_IDS=[to@email.com:]<CHAT_ID1>,[to@email.com:]<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}
