Thanks for the suggestions. I know that I just must not have explained my
situation clearly. Apologies for that... Here is my situation: The people
who I want to allow access to my mail server are not in my domain. They do
have shell accounts in my domain, but they do not dial in. My one friend
has an MSN account that he uses for Internet access. He doesn't have a
static IP address from MSN, so I can't enter a static IP into the
/etc/mail/access file as I have done for my laptop (which is in my domain).
I am not comfortable with the idea of a script automatically entering each
new IP that MSN assigns him though. I have worked with Netscape's Messaging
server before. From my experience with that product, I know that I can
authenticate valid users against the local user list without the need for
the sender's IP to be within the domain. Is it possible to get sendmail to
do that? I have created local shell accounts for my friends on my box, but
they are still denied the ability to send mail through my SMTP. Basically,
I want to be able to provide complete POP3 and SMTP mail services to my
friends without screwing up security. I know I could allow anyone from the
aol.com or msn.com domains to relay, but that is what I want to avoid. I
only want users with a mail username and password to be able to use my POP3
and SMTP services. Does this make sense?
Thanks for any insight,
George
