JavaMail的发送问题

以前在自己电脑上装了一个邮件服务器，用以前的代码都可以收发。

今天准备把它和126，163，什么的连上，问题出现了，一运行就报错，晕死我了。

弄了半天原来126已经不支持SMTP/POP3了，后来弄了个QQ邮箱，并且开启了SMTP/POP3，总算发上去了。

 

把发送的代码发下

form:

<form action="Send" method="post" name="mail">
			<table border="1" align="left">
				<tr>
					<td>
						From:
					</td>
					<td>
						<input name="from">secret:<input name="secret">
					</td>
				</tr>
				<tr>
					<td>
						TO:
					</td>
					<td>
						<input name="to">
					</td>
				</tr>

				<tr>
					<td>
						Subject:
					</td>
					<td>
						<input name="subject">
					</td>
				</tr>

				<tr>
					<td>
						Context:
					</td>
					<td>
						<textarea rows="10" cols="60" name="context"></textarea>
					</td>
				</tr>
				<tr>
					<td colspan="2">
						<input type="submit">
					</td>
					<td>
				</tr>

			</table>
		</form>

 一定要开启了SMTP/POP3，不然你再牛也发布上去
