T.S.
I installed PostfixAdmin with postfix and mariadb. After PostfixAdmin
set up the database, I populated it with adding domains and users
through the PostfixAdmin web interface. It seemed to write all the data
required to all the tables except the alias_domain table which is empty.
Does Postfix use this table? Is it Postfix that populates this table or
did PostfixAdmin not do this when it should have? The alias table looks
like it is used for all the user name and domain name mapping.
