The server in question (from which I derived my example log) does not appear to have any virtual aliases configured: # postconf virtual_alias_maps virtual_alias_maps = $virtual_maps # postconf virtual_maps virtual_maps = # I've also been able to reproduce this problem on my personal mailserver, though admittedly I *do* use virtual aliases on that one. Perhaps I'll see about reproducing this on a fresh test server. In case it matters, I forgot to mention that I've been using the Postfix build shipped in Debian stable (8.x "jessie"), i.e. 2.11.3-1. Thanks, Daniel
