I’m using Dovecot via LMTP for local delivery. I thought that postfix would receive information about non-existent users via that protocol, but I guess it doesn’t and ends up just accepting everything. So… is dovecot actually the thing that is generating the emails from mailer-daemon? Is there a way to get this setup to do the Right Thing? If not, why is LMTP even supported, because it seems to me that anyone who uses it will have this problem. (FYI, the reason I want to use LMTP is that I’m using sqlite for my user db, but postfix does not play well with sqlite when other programs are trying to access the same DB. I didn’t want to duplicate the user DB (I’m a big believer in the DRY principle) so I wanted to localize DB access to a single process, and that process has to be Dovecot.) rg
