I am against port blocking as much as the next guy, I just see port 587 as a disaster waiting to happen. ISP provided email credentials are universally transmitted in plain text. If an (insert any ISP here) employee can be arrested for selling email addresses to spammers, what keeps them from collecting and selling 587 credentials?
If you limit port 587 sending to let's say 1000 email per day you probably cover 99.9% of all normal users, and you're very likely to catch the spammers abusing an account. -- Mikael Abrahamsson email: swmike@swm.pp.se
