[Dovecot] 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.

The null envelope sender is used for very specific reasons
he does not talk about the null envelope
he tries to send back to the not relevant from-header and ignore the envelope-sender which is not much better
do not violate SMTP
there is a reason that the return path exists
instead break RFCs please do yourself and any other mailuser on this earth which maybe randomly affected by your misconfigurations a favour and read documentations
mailservers are a dangerous playground
