We found that the aliases based on beehive groups did not suffice for
us: actually we need lots of aliases, and some of those should not be
visible in the GAL (mainly the technical affines, one prominent
example being the postmaster address required for RFC 822 compliance,
see also Re: E-Mail sender verification and hiding items in the gal.
To implement this, we thought of the aliases file that comes with a
fronted postfix, but this file will not work, as postfix as a fronted
MTA is only routing, not delivering into beehive.
Oracle support recommended to use the /etc/postfix/virtual file: this
can serve to rewrite envelopes in a way that is what we needed.
One example to implement the abovementioned postmaster address:
Is there a way to create an email address for business purposes? For example, we use online software that requires us to use an email address. Currently we are listed as our legacy company, but want to change it to something like email@example.com. Can someone help with that?
