sending e mail

[arpit singla]

I am developing a shopping cart, i want to inform buyer of the tracking number by sending an email as soon as they check out the material.
If somebody could suggest me a way....
I know i will have to use smtp...but i dont know if there is a way of doing this without using smtp. I looked into JavaMail but it also requires smtp server. correct me if i am wrong.
I have tomcat as my webserver, has cloudscape as an embedded database in tomcat on W2K.
I tried to use PostCast smtp server, freeware but couldn't make it work. Please suggest me a way.
thanks for the help

Do you mind if I ask, what's the problem with using an SMTP server? It just seems like a curious requirement, that you're building a servlet app but can't use an SMTP server.

no problem using smtp server except that i couldn't get smtp server working. So was wondering if i could do without using smtp...
please let me know if there are any free available smtp server online which actually work.
thanks
