Starting mysql and sendmail

[Paul Lemmons]

By default, sendmail is setup to only allow connections from the local
box. So, you are "spam safe" in that regard.

To change sendmail configuration you go to /etc/mail and edit the
sendmail.mc file. Then do a make and a make install. Then a service
sendmail restart.

A real easy test of sendmail is to use the:

   mail somebody at localdomain.com

command. It will pretty much only work on your local domain, though,
unless your machine has both a DNS and Reverse DNS pointer on the
internet. Most places validate that the sender is "real" before
accepting email from them. They do this by looking at your IP address
and doing a reverse lookup on it. If it finds you, you are let in. If
not then your message is rejected.

You can look at the status of messages that have not been sent
successfully by issuing the "mailq" command.

Thanks, Todd. I'm going to put a lot of what you suggested to work. I
just called my ISP and, no, port 25 is not blocked. How can I check
that I am sending mail through my localhost machine? In Kmail I smtp
into the server, so I hope that is not what you meant.

I need to set it up so that it will send mail only from this local
machine, so that I will not become a spam-acquaintance. I thought that
google would send me to loads of info on this, but so far I remain
stuck.
