To disable them on SMTP level, simply tell sendmail you want to disable the
feature. Add noreceipts to confPRIVACY_FLAGS in sendmail.mc and reubuild
sendmail.cf from it. For example:
define(`confPRIVACY_FLAGS', `goaway,restrictqrun,noreceipts,noetrn')
Is this a good thing to do? I was thinking to enable this setting.
Thanks a lot to everybody for the feedback.
