I understand it can't send it anywhere (at least in my case, if the relayhost rejects the message, there's nowhere to send the message and/or the bounce), but can't it save the email in some local file, at least? Especially when the email originated locally (i.e. was not received via SMTP but via /usr/sbin/sendmail)? >> PS: Seeing now how postfix-users is happy to drop email on the floor, >> I'm starting the feel like maybe Postfix will also be happy to silently >> drop email on the floor, although that would make me wonder why it'd go >> through so much trouble to fsync things to stable storage, then. > The mailing list returns a message about unacceptable mail to the sender.

Could be, tho given the amount of email I have received and sent during the days that I sent messages to postfix-users, it seems hard to explain. Stefan
