Hardening a Lyris List Server

[<DonaldB () ecar org>]

Can anyone point me to any resources that you may have discovered
regarding properly securing a Lyris List Server? I realize I will have
to harden the box and keep tight FW rules, but I was hoping that someone
could point me toward resources that also consider Lyris specific
security concerns.

Thank you in advance!
