No. You write little functions in a common language (python, perl,
java, rust, haskell?, php, C) and leave the rest up to a code

There is a useful distinction to be made between mail that is injected into the
system by an
A useful rubric to keep in mind is:
* There's no such thing as outbound mail,
all mail comes in, and then it goes out...

Don't expand the alias.

Is this a setting in postfix? Is this a default behavior?
You are expanding the alias, by configuring a virtual(5) alias table

Im confused by this situation. Two separate independent servers both
running same version of postfix and both setup the same way with
virtual users and alias address stored in SQL.

Im confused by this situation. Two separate independent servers both
running same version of postfix and both setup the same way with virtual
users and alias address stored in SQL.
