Hi,
I have WIN98. I recently downloaded Javamail. Now i want to test my applications using JAvaMail. I need a SMTP server . Are there anything available for free/costeffective ?
For testing purposes i am still using ServletRunner only. Are ther any other free webservers that come with smtpserver also ?
Please help. Thanks

I found a big list of mail servers at:

I hope one or more of them will suit you.

You can try a few free or cost-effective SMTP servers like SMTPmart, Mailtrap, Gmail SMTP or SMTPget. These services are perfect for small-scale testing and should work well with your setup.

For a free web server that comes with an SMTP server, XAMPP is a good option.
