在SUSE 10.2上安装POSTFIX+CYRUS-IMAPD,用YAST2来调试真是方便.但正常配置后,局域网外发信会报错,监控25端口的通讯情况如下:
SMTP: 10:59:04 [tx] EHLO lenovo
SMTP: 10:59:04 [rx] 502 Error: command not implemented
SMTP: 10:59:04 [tx] HELO lenovo
SMTP: 10:59:04 [rx] 250 mail.xx.cn
SMTP: 10:59:04 [tx] MAIL FROM: < test@mail.xx.cn>
SMTP: 10:59:04 [rx] 250 Ok
SMTP: 10:59:04 [tx] RCPT TO: xx@mail.sina.com
SMTP: 10:59:04 [rx] 554 xx@mail.sina.com: Relay access denied
SMTP: 10:59:04 [tx] QUIT
SMTP: 10:59:04 [rx] 221 Bye
实际上SMTP已经配置支持认证,在局域网内也正常,经GOOGLE,原来是CISCO PIX防火墙的问题.
配置PIX:
NO fixup protocol smtp 25
.
问题解决!
