dovecot - Feb 2014 - Use header from instead envelope sender - quota exceed

Hi,

i want use dovecot and plugin quota to inform users about exceeded space. I
also configure postfix to rewrite envelope_sender so
envelope_sender<>header: from. Dovecot sent mail with information about
exceeded space to email in envelope_sender. It is possible to configure that
dovecot sent mail to header from address? I need use sender_canonical_maps
in postfix because i want also relay mail outgoing.

Thanks for helping me,
Piotr

Not sure I understand this, but if you are saying what I think you are 
saying, why on earth would you do this? This totally BREAKS smtp.

The null envelope sender is used for very specific reasons, and  you 
simply should NEVER rewrite it, unless you have a very special use case 
and know precisely what you are doing and why.
