Feature: SMTP sending with mixed case address
  Background:
    Given there exists an account with username "user@pm.me" and password "password"
    And there exists an account with username "bridgetest@protonmail.com" and password "password"
    And bridge starts
    And the user logs in with username "user@pm.me" and password "password"
    And user "user@pm.me" connects and authenticates SMTP client "1"

  Scenario: Mixed sender case in sender address
    When SMTP client "1" sends the following message from "user@pm.me" to "bridgetest@protonmail.com":
      """
      From: Bridge Test <USER@pm.me>
      To: Internal Bridge <bridgetest@protonmail.com>

      hello

      """
    Then it succeeds
    When user "user@pm.me" connects and authenticates IMAP client "1"
    Then IMAP client "1" eventually sees the following messages in "Sent":
      | from       | to                        | subject |
      | user@pm.me | bridgetest@protonmail.com |         |
    And the body in the "POST" request to "/mail/v4/messages" is:
      """
      {
        "Message": {
          "Subject": "",
          "Sender": {
            "Name": "Bridge Test",
            "Address": "user@pm.me"
