Email

Whilst most readers and writers are file-based, it is also possible to retrieve and send emails using the following:

• get-email - retrieve emails from an IMAP folder, FROM and SUBJECT can be stored in placeholders
• send-email - send emails via SMTP, the from/to/subject/body options automatically expand placeholders

The connection parameters are obtained through environment variables that are stored in .env files.

The following pipeline uses the get-email reader to poll the images folder for new messages with JPG attachments every 5 seconds. These images get downloaded and then forwarded to the send-email writer that attaches the images and then sends an email to the specified email address:

idc-convert -l INFO \
  get-email \
    -l INFO \
    -f images \
    -o {TMP} \
    -r ".*\.(jpg|JPG)" \
    -w 5 \
    --only_unseen \
    --mark_as_read \
    --from_placeholder FROM \
    --subject_placeholder SUBJECT \
  send-email \
    -l INFO \
    -f [email protected] \
    -t [email protected] \
    -s {SUBJECT} \
    -b "Message from: {FROM}"
