Emails sometimes not sending
Hi, i'm using Appwrite self hosted (v 1.4.13) and I have SMTP configured. When we try to login we don't always receive the login email. Sometimes it works, sometimes it doesn't. We are using AWS SES (sandbox mode) to send the emails.
Sometimes it works so I don't think its the configuration itself. It looks like a connection issue between the Appwrite container and SES but I can't pinpoint what it is. Could it be that Appwrite creates a connection, tries to do some logic which takes time and then tries to send the email? Because it looks like the connection is open for too long, no data is received so the connection is closed again.
The errors in the "worker-mails" container are:

TL;DR
The user is having issues with emails sometimes not sending in Appwrite self-hosted version 1.4.13. They have SMTP configured with AWS SES in sandbox mode. They suspect a connection issue between the Appwrite container and SES. The error messages in the "worker-mails" container indicate SMTP errors: "SMTP Error: data not accepted" and "MAIL FROM command failed, Timeout waiting for data from client".
Solution: It's possible that Appwrite creates a connection, performs some logic, and then tries to send the email, which may take too long and result in a closed connection. To resolve the issue, the user
