[mlmmj] replacing the address

[Alexei Babich <a.babich@xxxxxx>]

Hello all,
I'm trying to organize a mailing list based on mlmmj+postfix.
And required functionality of the mlmmj+postfix: requires that recipients of letters from mailing list not seen the real address of the sender, but the mailing list address instead. 
For example, in this letter, in my case, everything would have seen not Alexei Babich <a.babich@xxxxxx>, but Alexei Babich <mlmmj@xxxxxxxxx>.
Is it possible to do such a thing?

Thank you.
