A: 以root用户身份 postfix reload，postfix 并没用restart笔者也不建议你使用restart,reboot,restart这是一个坏习惯
A: 你可以在postfix的主要配置文件/etc/postifx/main.cf中修改下列参数:
queue_run_delay (默认值 1000秒) 设置多长时间队列管理进程去扫描无法投递的邮件
Maximal_queue_lifetime (默认值 5天) 设置邮件在队列里的最长时间
Minimal_backoff_time (默认值 1000秒) 在这个时间内，邮件不能够被锁定
Maximal_backoff_time (默认值 4000秒) 在这个时间之后，如果邮件仍然没有被投递，就认为是无法投递
qmgr_message_recipient_limit (默认值 1000) |
A: 以root用户身份登录 postconf -e disable_client_dns_lookup = 1 postfix reload
A: James S. Seymour用perl写了一个叫pflogsumm.pl的脚本，可以到这里下载：http://jimsun.linxnet.com/postfix_contrib.html,然后可以在crontab中添加下面的内容： 0 2 * * * /path/to/pflogsumm.pl -d today /var/log/maillog | mail -s "Mail Report" [email protected] 定时把分析报告寄给你,其它的一些使用参数可以看pflogsumm.pl里的信息。

A: 如果你安装了amavis它可以完成拒收.默认是弹回.如果你不想安装它,可以使用postfix的mime_header_checks
debian:~# postconf -e 'mime_header_checks=pcre:/etc/postfix/body_checks' |
创建body_checks文件内容如下：
debian:~# vi /etc/postfix/body_checks /^((Content-(Disposition: attachment;|Type:).*|\ +)| *)(file)?name\ *=\ *"?.*\.(lnk|asd|hlp|ocx|reg|bat|c[ho]m|cmd|exe|dll|vxd|pif|scr|hta|jse?|sh[mbs]|vb[esx]|ws[fh]|wmf)"?\ *$/ REJECT attachment type not allowed |
reload
