Hi, Im a bit new to linux, currently running two separate boxes, one for squid, which has now been up for 278 days !! and a newly installed Redhat 9 machine for use as a mail server. I run a small hom office.
I have a static public IP address, with A and MX records correctly set-up.
My firewalling is set-up to accept normal POP3, IMAP and SMTP ports, but i just need some help with the config of sendmail.
Im using Webmin to do most of my config, which based on my current machine is only running an FTP server and sendmail (POP,IMAP services running)
I can send mail, from say my hotmail account, my company account, ie to firstname.lastname@example.org
, and it arrives in the mailspool on my linux box, and using Webmin(localhost:10000, i can see the mail arrive, and check it locally on the linux box.
I can also read the mail from my win2000 machine on the same LAN (10.1.1.0) using outlook expre$$ or netscape.
The problem happens when i try to do a reply.
If i am logged in using the mail reader, such as outlook, i get the messge saying relaying not allowed, even though im on the same LAN as the linux box.
I want to be able to check my mail, when locally connected, say on my laptop that is on the 10.1.1.0 network, and also to be able to check my email and reply to messages, when i am say dialed in from a hotel with a different public ip address.
I know this is probably a simple one, but its got me stumped. I want to ensure i can reply, but not make my mailserver accessable to people trying to relay bad stuff.
Thanks in advance for any help
