《NetBSD指南-26.1.3.Using an alternative MTA》

[leo]

Starting from version 1.4 of NetBSD sendmail is not called directly:

代码: 全选

$ ls -l /usr/sbin/sendmail
lrwxr-xr-x  1 root  wheel  21 Nov  1 01:14 /usr/sbin/sendmail@ -> /usr/sbin/mailwrapper

The purpose of mailwrapper is to allow the usage of an alternative MTA instead of postfix (for example, sendmail). If you plan to use a different mailer I suggest that you read the mailwrapper(8) and the mailer.conf(5) manpages, which are very clear.
