how to reproduce:

1) configure an auto response (absense notification)
for a mail account in bejy

2) spammer sends a mail to this account with invalid
sender address (user part invalid, domain valid)

3) bejy sends sends an auto response to the wrong sender
(i.e. microsoft.com)

4) postmaster@microsoft.com bounces this mail as
undeliverable back to bejy

5) bejy sends the next auto response for the bounced mail

6) back to 4)

Possible solutions:

- bejy should count the sent auto responses per sender
- auto responses should not be sent if sender is postmaster

 - bejy should count the sent auto responses per sender


I guess this would require to much state information.

 - auto responses should not be sent if sender is postmaster


Could be easily implemented.

But
  spammer sends a mail to this account with invalid
sender address (user part invalid, domain valid)


Preferred solution is to enable the "validateSender" option, to avoid incoming mails from invalid mail accounts.
