Only allow mail from 1 server

Not really. Sendmail will accept mail generally from any box as long as
the mail is destined for that server. Firewalling is the best route to
go.

Hi

 

I have a machine running Mailscanner/Sendmail where users also pop there
mail off.

 

I want to move MailScanner to a couple of machines that scan the mail
then forward onto the box where the users actually pop there mail off.

 

Ill get rid of the current MX record for the POP machine and create MX
records for the 2 MailScanner Machines. I want to ensure the POP machine
can only recieve mail from the 2 front end MailScanner Machines. I guess
I can use a firewall to only allowing incomming connections from the 2
machines but is there a way you can achieve this within sendmail?

 

Thanks


Paul
