How would that help? Their clients do not use SMTP AUTH but rather send
usual mail. From e.g. ships via satellite without SMTP proxies. Or
managing directors sending important mail from dynamic IPs etc. If I
tell our client to not accept that mail and teach his/her customers to
finally setup a correct mail service they will fire me right away since
they need those mails and it is not really considered good style to
"educate" your customer...
