Thank you for your feedback. I'm sorry to hear you're experiencing timeout issues with the app. I'm not entirely sure what might be causing this problem on your end. The app has been thoroughly tested against multiple SMTP servers and is working as intended. However, I understand how frustrating this must be for you. To help us identify and resolve this issue, could you please provide some additional details about your setup? This might include: - Which SMTP server/email provider you're using - Any specific error messages you're seeing - Your device and OS version - Network environment (corporate, home, etc.) I'm committed to getting this working properly for you and would be happy to work together on finding a solution. Once we resolve this, I'd greatly appreciate if you could consider updating your review. Please reach out to me directly at dorian@borovina.com with the additional details, and I'll prioritize getting this fixed for you. Thank you for your patience, and I look forward to hearing from you soon.
