邮件发不出

yongsc

我的邮件服务器若通过ADSL直接拨号上网，收发邮都没问题，<br>
但是通过ZYWAL2防火墙上网就发不出邮件，有以下提示：<br>
Attempting to send message to gateway.<br>Attempting SMTP connection to [xxx.xxx.xx.xxx : 25]<br>Waiting for socket connection...<br>220 domain.com ESMTP MDaemon 6.7.9; Sat, 07 Feb 2004 19:15:58 +0800<br>EHLO domain.com<br>Socket connection established<br>Waiting for protocol initiation...<br>250-domain.com Hello domain.com, pleased to meet you<br>250-ETRN<br>250-AUTH=LOGIN<br>250-AUTH LOGIN CRAM-MD5<br>250-8BITMIME<br>250 SIZE 0<br>MAIL From:<aaa@domail.com> SIZE=1445<br>550 Sorry, <aaa@domain.com> is not allowed access from your location<br>QUIT<br>
请赐教！<br>

撕裂的肺

这是什么防火墙？硬件的吗？

是硬件防火墙，这个提示是MD的提示。
