Sendmail Questions

Sanjay Tailor — Mon, 29 Oct 2001 19:12:33 GMT

Hello,

I have sendmail running and want the server to reject all incoming mail from outside. Basically, I only want to send mail within the server. Can this be done? I do not have DNS running.

Thanks for your help,
Sanjay

If you're just sending mail, then you don't really need to have sendmail running. Your mail client should be able to connect to recipient machine.

Hope this helps.

Hi,

If I understood your question correctly then,

No need to run sendmail process for server internal mails.

Goodluck,

Santosh is correct, if you aren't using sendmail, shut it down for security reasons, because you don't need it to send mail.

And as for security issues, link to this, print it, and consider some of the options:

Hello,

Thank you for your answers. How do i safely turn off sendmail. I checked the man page and I found a sendmail -bk option which will kill the daemon. How do I set my startup files so that when I reboot, it will not turn on sendmail.

Thanks again,

Sanjay
