如何logging整个SMTP会话，包括与后缀的数据？

我正在使用postifx 2.11.3-1运行Debian 8.5，并且尝试将包括DATA在内的整个smtp会话logging到mail.log 。

可以通过在master.cf的smtpd中添加-vvv来增加详细信息来查看部分数据（参见下面的整个文件），但是我不可能获得完整的数据，只有前10个字符正在被logging。

mail.log

 --- snip --- Sep 18 18:22:03 vagrant postfix/smtpd[9220]: rec_put: type T len 17 data 1474215723 Sep 18 18:22:03 vagrant postfix/smtpd[9220]: rec_put: type A len 18 data log_ident= Sep 18 18:22:03 vagrant postfix/smtpd[9220]: rec_put: type A len 21 data rewrite_co Sep 18 18:22:03 vagrant postfix/smtpd[9220]: rec_put: type S len 23 data foo@exampl Sep 18 18:22:03 vagrant postfix/smtpd[9220]: rec_put: type A len 25 data log_client --- snip --- 

还通过增加冗长的后缀真的logging了很多。 有没有更好的办法，而不是提高冗长度？

• 服务器向root / postmaster发送无法控制的电子邮件数量
• Postfix忽略Google Apps的MXlogging
• Ubuntu与Postfix邮件转发，DNSlogging（MX，SPF，DKIM）需要？
• nginx / php-fpm – 405错误提交电子邮件联系表单
• 从VPS转发邮件

据我发现它只能使用tcpdump或whireshark真正只loggingsmtp会话，我看到这个正确的？

我想要login的例子smtp会话：

 telnet www.sample.com 25 Server Response: 220 www.sample.com ESMTP Postfix Client Sending : HELO domain.com Server Response: 250 Hello domain.com Client Sending : MAIL FROM: <[email protected]> Server Response: 250 Ok Client Sending : RCPT TO: <[email protected]> Server Response: 250 Ok Client Sending : DATA Server Response: 354 End data with <CR><LF>.<CR><LF> Client Sending : Subject: Example Message Client Sending : From: [email protected] Client Sending : To: [email protected] Client Sending : Client Sending : Yo, Client Sending : Client Sending : Sending a test message. Client Sending : Client Sending : Later, Client Sending : Carl Client Sending : . Server Response: 250 Ok: queued as 45334 Client Sending : QUIT Server Response: 221 Bye
