Android Mail – Outgoing SMTP Setup for mySMTP (2025)

Use this guide to send emails using your mySMTP SMTP server from any Android device. You can leave incoming mail settings as-is if you’re only using SMTP for sending (e.g., newsletter or notification replies).

Step-by-Step: Outgoing SMTP Configuration

Open the Mail or Gmail app on your Android device
Go to Settings > choose the email account to configure (or add a new one if needed)
Scroll to the Outgoing server settings section
Enter the following values:

Setting	Value
SMTP Server	relayxx.xx.xxx (from setup email)
Port	587
Security Type	STARTTLS or TLS
Require sign-in	Enabled
Username	Your mySMTP username
Password	Your mySMTP password

Tap Next and finish the setup. Gmail may perform a connection test.

Important Notes

Do not use SSL/port 465 — mySMTP requires TLS/port 587

Make sure the From address belongs to a domain with proper SPF/DKIM/DMARC
If you’re only sending, incoming server fields can be skipped or set to dummy value
