Is there any possibility to disable returning message to sender, if email delivery failed? I have a few emails per day "This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. [error description]".
It is a bit annoying. Because I have 13k users, someone always has damage the e-mail server or problem with email address or quota limit etc. and e-mails are returned to the sender address, that is my forum address, because the forum sends notifications about new posts, PM, etc. So I have to regular clean email box. I know, it is not phpBB problem but is there any possibility to disable it?
