Hello,

I am running a docker version of Apache James on AWS and I can connect to the 
server using IMAP but not SMTP and this is the error I am getting:

javax.mail.SendFailedException: Invalid Addresses;  nested exception is: 
com.sun.mail.smtp.SMTPAddressFailedException: 530 5.7.1 Authentication Required

I am using Spring Boot version 2.5.4 and deploying my application using 
Kubernetes. Interestingly, when I run Apache James on my laptop the code works 
fine, but not when deployed on AWS.

This is my mail properties:

spring:
  mail:
    host: apachejames
    port: 25
    properties.mail.smtp.auth: false
    properties.mail.smtp.starttls.enable: false
    properties.mail.imap.host: apachejames
    properties.mail.imap.port: 143
    properties.mail.imap.starttls.enable: false




I’ve been stuck on this issue for several days, so all help welcome 😊

Thanks in advance,
Sean
