I grouped an email into one mailing list:
group name : department
email : email@example.com
here is the problem:
when i send an email to firstname.lastname@example.org and cc:email@example.com, at firstname.lastname@example.org's end, email@example.com will look like firstname.lastname@example.org. therefore, when email@example.com replies, the email will never get to firstname.lastname@example.org.
