[pfx] local_recipient_maps does not apply to local mail submission

[Étienne Miret via Postfix-users]

Hello,


 - be rejected for mail received from the Internet,
 - still get mails from the sendmail commnd and



I found this behavior surprising.




<https://www.postfix.org/postconf.5.html#local_recipient_maps>
and <https://www.postfix.org/LOCAL_RECIPIENT_README.html>.

I did find it specified on an old message to this list:
<https://www.mail-archive.com/postfix-users@postfix.org/msg71295.html>.
so I guess it’s not a bug. But why is Postfix working like that?

After troubleshooting an issue on my Postfix server, I found out that the local_recipient_maps parameter is ignored for locally submitted emails. That is, a recipient not listed there will: - still get mails sent from Internet to some other address that is aliased to them. For one thing, I find odd to have Postfix behave differently for local domains depending on the origin. Obviously, that’s a strong requirement for the default domain class, but for the others? And second, this behavior isn’t really documented. I saw no mention about it looking at Also, in case it is better to keep this behavior, could it be specified in <https://www.postfix.o/postconf.5.html#local_recipient_maps>?

Regards,
