Management tools for Postfix or Sendmail

[Budi Febrianto]

Tried webmin, and I think its works. Thanks.
I think I remember trying this tools before, but because I want to learn
linux so I stick with console text.

Sure, that mailq command still works in sendmail. But for daily
administration is bad.

First, I just want tools to monitor all pending emails, but know I can do
more.

Question: for configuring postfix or sendmail. Is that recommended to use
webmin? Or should I use text editor instead?
