反正是有,我检查身份验证信息(用户名和放大器;密码和放大器;电子邮件地址),因为我需要检查所有SMTP信息是否有效?我之前问。
Is there anyway that i check authentication information (username & password & email address) as i need to check all smtp information is valid or not? that i asked before..
推荐答案
有一个在SMTP(参见RFC 821),没有用户名和密码,所以没有办法测试。 你可以使用一个MAIL FROM和RCPT TO序列中,但不发送任何数据,就看你会被允许发送邮件给定的信息,而不发送实际的邮件。
There's no username and password in SMTP (see rfc 821), so there's no way to test that. You could use a MAIL FROM and RCPT TO sequence, but not send any DATA, to see if you'll be allowed to send mail with the given information, without sending an actual mail.
