We have a server running qmail that collects mail for several domains. The problem is that once a specific username is taken by one of the domains, none of the others can use it.
So for example if we setup email@example.com, then we are unable to also set up firstname.lastname@example.org
We need qmail configured so that we can use any username with any domain. We manage our accounts through qmailadmin and so once the configuration to qmail is made, qmailadmin will need to allow us to setup the email accounts with the same username.
This should be a very quick and easy fix for someone. Please don't bid unless you are able to start on this immediately.
