I offered Sam a patch for 1.3.8.mumble and for 1.3.9 to overcome this and return EX_NOUSER instead, but never got a reply. Before I offered the patch, I had been told to not accept mail for unknown users, but on some MTAs, "unknown user" rejection won't work depending on how mail comes in (SMTP vs. sendmail) and how maildrop is integrated.

Sam?

Not sure if it still applies to 1.4. Unpack your source, save this mail, cd to the source directory, apply the patch with

patch -p1 <where-you-saved-this-mail

and recompile and reinstall maildrop. Reusing an existing unpacked maildrop source tree and patching that should also be fine.

This fixes your problem for me, but make sure that you reject mail for unknown users at your SMTP port as well, to avoid unnecessary mail + bounce traffic.
