Sorry but I disagree with Per. ISPs have a duty to prevent email Spam which is a terrible curse for us all. If they decide that blocking port 25 outbound will help then they should do it.
If you are a user, why can't you use the ISPs relay server? If you are a provider you ought to have your own mail server on a fixed IP address.
Of course, one day we need a better protocol than SMTP (*Simple* Mail Transfer Protocol) which was never meant as a global email solution. But until then we have to do something to stop people abusing it.
Just my 2p worth

Wouldn't that make customers go to another comany for service?
Most probably. About three years ago, prior to us becoming a service provider ourselves, we were "just" a customer, and had to sack our provider when they decided to reduce their service by blocking port 25.
Personally, I believe any and all restrictions on an internet connection must be be very clearly and very obviously stated in the product/ service description, and that is something many ISPs neglect to do.
