The two approaches solve different problems. Keep in mind that
- virtual-alias expansion is implemented in the cleanup daemon,
- the smtpd daemon reads the virtual-alias table to decide if a
recipient address may be invalid.
If you use different virtual-alias tables in different places,
then you can expect problems with recipient address validation.
I recommend doing all the virtual-alias exansion in one place, and
not complicating the configuration with different virtual-alias
tables.
