## Task 1 - Basic MX

Packages are installed from repository.

For some reason, sendng email from mac client didn't work but from ubuntu worked fine.

    echo "From my machine" | mail -s subject postmaster@10.90.138.124

Updated in postfix config:

    allow_min_user=yes
    resolve_numeric_domain=yes
