There are, quite a few of them, and many others want you to register 
with them if you want to send SMPT mail directly. In fact it is getting 
to the stage where there _aren't_ plenty of ISPs who permit port 25 traffic.

Third-party email services will

Googlemail,Hotmail and other web-based email services will send SMPT 
emails for free, and there are several independent mail servers (eg 1&1 
run one) which charge about £10 per annum.


One question, when you send an email to a relaying mail server, perhaps 
operated by your ISP, where the mail server is the SMTP client rather 
than you, what port number does the communication between you and the 
mail server use?
