Hi,
i just finished installing iRedMail and hooking it up to my AD domain (LDAP). I have a question about lists. At the moment i can make a group (lets say team1 for example, with two members, test1 and test2) and when i send a mail to team1@mydomain.com, everything works just fine... they both get the letter.

There are two things however that bother me. First is that i have used mailman thus far for mailing list and I find it very good that it adds [List_Name] at the beginning of every letter (that comes from list) making the "list letters" very easy to identify. I was wondering is it possible to make something like that to my current setup as well?

Second problem  is that at the moment anyone (from my domain at least) can send mails to the list, but i'd like to set it so, that only members of the team1 group can send mail into that list.

PS: Ofc one possibility would be to install mailman, but i'm not sure how to make it work with my current setup (because i changed quite a lot of stuff following this guide)
