Turning off firewalls not recommended
I've been on the internet far before the invention of the hypertext. And it's still astonishing to see how many mis-conception about it. First of all SMTP never use IDENT. Second of all, for all paranoid people, stop all your crap about been hacked behind a NAT. Even if there is some port open on OSX, it can't be access from other computer, and in the case that you have enable some sharing stuff on your computer, the built-in firewall configuration in Jaguar will unfilter this port.

Of course SMTP never uses ident, they're two different protocols. But that doesn't mean that SMTP servers never make use of ident.
When I posted that first comment I'd never come across an SMTP server that made ident requests, but it seems sendmail for one has the ability to do so. Try using Google (like I did) before dismissing a possible solution out of hand. And I can't see anywhere that anyone has claimed you can be hacked through NAT without some further compromise - at least that's how I interpret sben's line 'compromise of the primary firewall' |
