![如何阻止 Dovecot 记录到系统日志](https://linux22.com/image/1154067/%E5%A6%82%E4%BD%95%E9%98%BB%E6%AD%A2%20Dovecot%20%E8%AE%B0%E5%BD%95%E5%88%B0%E7%B3%BB%E7%BB%9F%E6%97%A5%E5%BF%97.png)
我运行的是 Ubuntu 16.04,其中安装了用于 imap 的 Dovecot 软件包和用于其 Web 界面的 Roundcube。一切都运行正常,只是我无法让 Dovecot 停止将 imap 登录和 imap 注销记录到 syslog。

没有帮助。
在 syslog 和 mail.log 中都会记录的内容以及我希望仅记录在 mail.log 中的内容:
Feb 22 10:00:31 n40l dovecot: imap-login: Login: user=<[email protected]>, method=PLAIN, rip=::1, lip=::1, mpid=16286, secured, session=<eg2dRsllCusAAAAAAAAAAAAAAAAAAAAB>
Feb 22 10:00:31 n40l dovecot: imap([email protected]): Logged out in=91 out=928
附注:cron 仍然坚持记录到 syslog,也无法停止。不确定是否有相同的原因。
问题:如何让 Dovecot 仅记录到邮件日志设备而不记录到系统日志?
答案1
通过以下方式创建完整配置:
doveconf -a > fullconfig.txt
在其中查找具有作为目的地的隐式日志记录选项= syslog
。
将所有不需要的更改为= /dev/null
。
答案2
老问题但答案可能仍然对某些人有帮助。
要停止记录到 /var/log/syslog,您应该将 mail.none(和 cron.none)添加到 rsyslog 行,使其变为:
*.*;auth;authpriv.none;mail.none;cron.none -/var/log/syslog
看https://superuser.com/questions/1060190/what-does-the-none-suffix-mean有关“无”后缀的详细信息
答案3
/var/log/mail.log
强制调试和信息消息仅登录,syslog
不再登录
# /etc/dovecot/conf.d/10-logging.conf
debug_log_path = /var/log/mail.log
info_log_path = /var/log/mail.log
