Reportportal: Unable to set up email integration with service account as username [v5]

[andrzej-kodify]

Describe the bug
Try setting setting up e.g. AWS SMTP server where username is service account (i.e. not a valid email address)
Since as far as I understand the code tries to send email to that username here
https://github.com/reportportal/service-api/blob/a256236df4f9687775429f25cda0a816bf6a4c29/src/main/java/com/epam/ta/reportportal/core/integration/util/EmailServerIntegrationService.java#L131
it obviously fails with

An error occurred while connecting to server: Email server is not configured or configuration is incorrect. Unable to send connection test email. Failed messages: javax.mail.SendFailedException: Invalid Addresses;
  nested exception is:
    com.sun.mail.smtp.SMTPAddressFailedException: 501 Invalid RCPT TO address provided

As a workaround it seems that connection test is not invoked when you add new email integration first without auth enabled, edit it and then change configuration 🙄

For now we do not support integration with the AWS e-mail server.
We have added it the backlog
