Hi,
I have a strange networking problem relating to Sendmail, SMTP &
PPP. Here's a brief discription:
All of our E Mail to & from the internet is sent through our mail hub
(a Linux Box which connects to our mail provider using UUCP). This
is good.
However, here's the rub. When I connect to our ISP using ppp, all of
our Internet E Mail gets routed to the ISP rather than the UUCP host.
E Mail for the whole company should be entirely routed through the
UUCP host. I don't know if this is how its intented to work &
generally I'd say its a pleasant boon, however, I need to have mail
routed to the UUCP host.
I can't remove the TCP/IP section of sendmail because we use SMTP on
many computers which all use the single Linux Box as the mail hub.
Since we are only dealing with one ISP can I block out all SMTP
activity to that one domain?? Or do I have to block out the connects
at the sendmail level??
I have a linux box running 2.0.15, ppp-2.0.7f. Sendmail
5.67b/IDA-1.5 (yes I know about the broken flock() emulation).
I also use IP Masquerading (IPFWADM 3.0).\
Thanks in advance for any help,
