Why are you listing all recipients on one line.

The Postfix aliases(5) manual page says:

:include:/file/name
Mail is sent to the destinations listed in the named file.
Lines in :include: files have the same syntax as the right-hand
side of alias entries.

It says LINES, i.e. plural. It does not say LINE, i.e. singular.

Postfix will not permit arbitrarily long lines in :include: files
(or for the same reason, in .forward files). Such files are often
maintained by untrusted software or users. Untrusted software or
users MUST NOT control how much memory a Postfix daemon processes
will use.
