I haven't implemented postscreen yet, but plan to. So this question is for the postscreen experts here.
As I understand it from the documentation, postscreen protects postfix from having to deal with most attack vectors, including higher volume attacks. So, does it make sense to also use something like fail2ban to block IPs that postscreen (or postfix) logs repeatedly as offenders? Or is postscreen sufficient to protect posfix? Thanks much, Michael
