Set up PocketBase mail settings over SMTP

PocketBase sends verification, password reset, email change and OTP emails, and by default hands them to the server's `sendmail` command. Switch it to SMTP under **Settings → Mail settings** in the dashboard; the values are stored with your app's settings, so there's no file to edit. The TLS choice sits under **Show more options**: **Auto (StartTLS)** is for 587 and **Always** is for 465.

1. 1

   Create a send-only key

   In Unitpost, open Settings → SMTP and create a send-only key. PocketBase's Sender address must be on a verified domain.

2. 2

   Fill in Mail settings

   Turn on Use SMTP mail server, then click Show more options to reach the TLS setting.

   Sender name	Your app
   Sender address	no-reply@yourdomain.com
   SMTP server host	smtp.unitpost.com
   Port	587
   Username	unitpost
   Password	Your Unitpost API key
   TLS encryption	Auto (StartTLS)
   AUTH method	PLAIN (default)

   For port 465, set TLS encryption to Always.

3. 3

   Save and send a test

   Click Save changes, then Send test email. Pick a template such as Password reset and an auth collection, enter a To email address and click Send. The message shows up in Unitpost Emails.

4. 4

   If the test fails

   535 5.7.8 means Username isn't unitpost. 550 5.7.1 means Sender address isn't on a verified domain. A timeout on 465 means TLS encryption is still Auto (StartTLS).
