I need to forward one of my mailcow email adress (aka firstname.lastname@example.org) to several (15) external mail adresses (aka email@example.com, firstname.lastname@example.org, …).
I would like to ask you some advices on this:
- should I set aliases or a Sieve filter?
- is it safe (for the IP reputation) to do so?
- or is there is a better way to achieve this goal?
Thank you in advance, moo,
