sendmail accept mail from only 1 ip-address ?

[Jesper Sivertsen]

Hi

I have a spam-box to receive my mails and check them for spam and virus.
So now i want my HP-UX to only accept mail from my spam-box.
I am using sendmail on HP-UX 11.11
I have changed my MX record to point to the spam-box, byt i still get spam-mail on my HP-UX box.
Howe can i block all incomming mail but the spam-box ?

Best regards
Jesper Sivertsen

The easy way is to block all the connections to the port 25 on your HP-UX box, and only accept the conections from your SPAM-box.

This can be done configuring the inetd.sec

You can do this with access.db

cd /etc/mail
vi access

ip-of-spam-box relay
1 reject
2 reject
.
.
.
254 reject

tab between ip and relay or reject

makemap hash /etc/mail/access
restart sendmail....

Hi again

I can not use inetd.conf because sendmail is not started from inetd but from rc.

I will try the other solution that seems right !

I think Geoff is right

inetd.conf controls how different serives on the system work and allows you to restrict services as Geoff has shown you. hopee this clarifies the inetd.conf for you.
