我的 ubuntu 服务器出了问题。有人在某处添加了他的电子邮件，我的服务器试图向他发送电子邮件。我使用 grep 进行了搜索：
/var/log # grep -n "[email protected]" *
并得到这个：
syslog.1:6538:Aug 21 03:39:54 lovecakes postfix/smtp[24625]: A49A315A951: to=<[email protected]>, relay=gmail-smtp-in.l.google.com[64.233.165.27]:25, delay=2.9, delays=1.2/0/0.46/1.2, dsn=2.0.0, status=sent (250 2.0.0 OK 1408585194 wr8si36296852lbc.79 - gsmtp)

我的别名是干净的：
# vim /etc/aliases
我不知道在哪里找到他的条目并将其删除，以便我的服务器停止尝试向他发送电子邮件。
答案1
root@myserver /home # grep -r 'guys_name' /etc
Binary file /etc/postfix/transport.db matches
Binary file /etc/postfix/recipient_bcc.db matches
在那里找到了他。
