port 26 FTW!
in all seriousness, most isp's (consumer provider folk) today do some
form of blocking of port 25, if you are 'smart' enough to evade this
sort of thing, then you can still do email/blah. 99.999% of users are:
1) not interested in bypassing it
2) not clued into what's going on
3) using webmail
Why is this debate still ongoing??
