aaPanel_Kern aaP_sktattoo Shows that authentication failed. Check if the email address and password are correct?
aaPanel_Kern aaP_sktattoo can send from the sending interface on the mail server without a password. The mail client needs to set the account password
aaP_sktattoo aaPanel_Kern 客户端需要设置 现在问题是邮件服务器上也发布出去，之前能发，突然就发不出去了，我问你，你说可能是密码错误，但是邮件服务器发送不需要密码，就自然没有密码错误的这个问题了。那又是什么问题发件失败呢？
aaPanel_Kern aaP_sktattoo The mail server does not need a password because the user data is directly obtained. The erp system (that is, the client) needs the correct password to log in to send mail.
aaP_sktattoo aaPanel_Kern 我现在就没有使用erp，也没有使用客户端，就是在宝塔后台正常发送，也发送失败，强调，没有使用客户端没有使用erp，就是在宝塔后台面板里发不出去宝塔后台面板里发不出去
