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@xxxxxxxxxxxxxxx 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. -----Original Message----- From: fedora-list-bounces@xxxxxxxxxx [mailto:fedora-list-bounces@xxxxxxxxxx] On Behalf Of Dotan Cohen Sent: Tuesday, August 23, 2005 3:33 PM To: For users of Fedora Core releases Subject: Re: Starting mysql and sendmail On 8/24/05, Todd Nine <todd.nine@xxxxxxxxx> wrote: > 3.

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.
