Hi,

search for null sender in INBOX for me is:

doveadm search -u USER mailbox INBOX HEADER Return-Path '<>'

because in my received mails the Header field "Return-Path" contains the envelop sender.

Other way is to search for MAILER-DAEMON in from field:

doveadm search -u USER mailbox INBOX from 'MAILER-DAEMON@DOMAIN'

Hi,

I tried to search for mailer daemon messages but can't find a syntax for the null sender.

all these does not work: doveadm -u xxx from "<>" doveadm -u xxx from <> doveadm -u xxx from ""

any ideas?

Thank you Daniel
