Question about forwarders to external mail

Hello, everybody.
I need to forward one of my mailcow email adress (aka comunity@mailcow.email) to several (15) external mail adresses (aka bob@gmail.com, john@yahoo.it, …).

I would like to ask you some advices on this:

Thank you in advance, moo,
Joseph

Recommended for forwarding to external addresses is by using a Sive filter.
But I don’t know what the difference is to forwarding by alias.

Well I don’t know the difference between aliases and sieve but I followed your advice.
I’ve set a sieve filter wich is working ok:

if anyof (address :contains "to" "comunity@mailcow.email") {
    redirect "bob@gmail.com,";
    redirect "john@yahoo.it";    
    keep;
}

Also find a good guide here: https://kb.vircom.com/Kbase/redirfile.asp?id=581&SID=
Thank you and have a nice day yall.

Is there any difference on using sieve filters and setting the forwarder on Sogo?

I am wondering the same?
