I'm trying to set up internal aliases for local users via: echo firstname.lastname@example.org > /var/qmail/alias/.qmail-root echo email@example.com > /var/qmail/alias/.qmail-mailer-daemon chmod 644 /var/qmail/alias/.qmail* .. etc This works on other Qmail set up servers, just not my plesk server which is obviously using Qmail. And yes, I did use a real email address and not firstname.lastname@example.org. To test it, I ran "mail root" as a locla user. The email did not get through nor can I find anything in the maillogs. I ran "mail email@example.com" which worked perfectly. So it's something to do with the aliases, I just don't know what is different between the Plesk/Normal Qmail installations.
