And it may also be the case that in order to prevent the propogation of spam and other nasty stuff, your ISP blocks you (and its other customers) from sending to port 25 of any machine except its own mail relay. The it can enforce some kind of control, perhaps rate limiting, perhaps content inspection (as some governments are now getting more aggressive about demanding of ISPs) but certainly stopping you using some other 'open relay' host.
IIRC, lynn was somewhere in Spain. ISPs here, to my knowledge, do not block port 25, because they also do not allow you to send with a from address not belonging to their servers. IE, even after password ID, they don't do relay for their own customers. But then again, that school might use a transparent VPN to connect to the rest of the school system. Some do here. You get out via proxy set by the state IT staff. There is a *lot* of variance here. As often as not, the schools are provided with Linux machines which are then reformatted with pirated copies of Windows by the teachers, because nobody thought to train teachers in Linux first. Or not enough. Or because the IT staff on call takes days or weeks to come. - -- Cheers, Carlos E. R.
