Ah, but that seem to be the case now. I do not have the destination for that user in "smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd" yet it attempts to deliver to the correct destination and attempts to authenticate. yet when "smtp_sender_dependent_authentication = no" it makes no attempt to authenticate to the very same target server. > > It is possible to separate the per-sender and other email streams, > but that is a bit more complicated, because most people don't have > your requireents. > > This uses sender_dependent_default_transport_maps, where all > per-sender default transports share a customized Postfix SMTP cient > with its own smtp_sasl_passwd_maps setting in master.cf, which has > all the per-sender entries. > > The other email streams use the 'normal' Postfix SMTP client with > only per-destination entries in smtp_sasl_passwd_maps. > > Wietse This does look a bit complicated and I hesitate to hack at it without further eyeballing. Not sure I see how this helps "coax" postfix to not authenticate on this one inbound user. Perhaps I just need to think about it more. joe a.
