Installed umbraco v 4.0.2.1 (Assembly version: 1.0.3441.17657) under Windows XP + IIS 5.1, and every thing is OK.

Setup IIS SMTP Service successfully.

Installed the Runway module, including the Contact Form.

The contact form is working properly, and the emails are being sent as expected.

The only problem is that if you setup the subject to a value like "This is a very long subject", the email are not being sent. Basically, no errors are reported, and nothing happens.

If I hard code the string value "This is a very long subject" inside the code-behind "Contact.ascx,cs" as follows:

umbraco.library.SendMail(tb_email.Text, yourEmail, "This is a very long subject", tb_msg.Text, true);

it works successfully, the the email is sent.

But, if I make it like this:

umbraco.library.SendMail(tb_email.Text, yourEmail, subject, tb_msg.Text, true);

nothing happens, no errors, and no email is being sent.

What is the problem ?

Reported this in codeplex: http://bit.ly/j0AMB.
