SMTP & API Email Fix on VPS
Budget: £20 – £250 GBP
I need an expert to resolve email delivery issues on my Contabo VPS (Ubuntu 24.04). We use a Python script to send daily CSV files via email using Resend API and Gmail SMTP as a fallback. Currently, emails are not being received.
Key Tasks:
• Unblock SMTP ports (587/465) if blocked
• Configure Resend.com API to send emails with CSV attachment
• Set up Gmail SMTP (via app password) as fallback relay with TLS
• Ensure correct MIME headers and content boundaries
• Verify email receipt with correct attachment
• Log all steps (Python logs + system mail logs)
Ideal Skills & Experience:
• Proficiency in Linux (Ubuntu)
• Experience with Resend API and Gmail SMTP
• Knowledge of Python scripting and email protocols
• Familiarity with email delivery troubleshooting
