CreateRecovery using Flutter results in no email received (self-hosted) Error: Could not authenticate.

### 👟 Reproduction steps When I run this: ``` var token = account!.createRecovery( email: 'richard@hyperbook.co.uk', url: 'https://intelvid.co.uk/#/change_password' ).then((ok){ print('(SMTP1)${ok.userId}++++${ok.$id}===${ok.$createdAt}****${ok.phrase}^^^^${ok.secret}'); }).onError((e, t){ print('(SMTP2)${e}++++${t}'); }); ``` I think I have set everything up OK. I can send an email from the Appwrite console. ### 👍 Expected behavior I should receive an email at richard@hyperbook.co.uk ### 👎 Actual Behavior Nothing received No error indicated to F;utter app. This is the console: (SMTP1)68b990d8001d421b49ec++++68b9a6f573cfea2bcd36===2025-09-04T14:49:25.474+00:00****^^^^ I ran this on the server: ``` docker compose logs -f appwrite-worker-mails ``` and got this: ``` appwrite-worker-mails | [Error] Type: Exception appwrite-worker-mails | [Error] Message: Error sending mail: SMTP Error: Could not authenticate. appwrite-worker-mails | [Error] File: /usr/src/code/src/Appwrite/Platform/Workers/Mails.php appwrite-worker-mails | [Error] Line: 145 appwrite-worker-mails | [Job] Received Job (68b9a5fa0aac07.45553342). appwrite-worker-mails | [Job] (68b9a5fa0aac07.45553342) failed to run. appwrite-worker-mails | [Job] (68b9a5fa0aac07.45553342) Error sending mail: SMTP Error: Could not authenticate. ``` ### 🎲 Appwrite version Different version (specify in environment) ### 💻 Operating system Linux ### 🧱 Your Environment When I type appwrite -v I get 6.2.2 ### 👀 Have you spent some time to check if this issue has been raised before? - [x] I checked and didn't find similar issue ### 🏢 Have you read the Code of Conduct? - [x] I have read the [Code of Conduct](https://github.com/appwrite/.github/blob/main/CODE_OF_CONDUCT.md)
