Send SMTP Email

Use this skill when the task is to send a simple email through SMTP with a mailbox account.

Embedded SMTP Config

If the runtime environment does not support .env, use the following embedded configuration block. The sending script can fall back to this block when the env file is missing.

# Provider preset: 126, qq, sina, aliyun, custom
EMAIL_PROVIDER=126

# If EMAIL_PROVIDER=custom, fill these yourself.
SMTP_HOST=smtp.126.com
SMTP_PORT=465

# true for SMTPS on port 465, false for STARTTLS on port 587.
SMTP_USE_SSL=true
