Hi Everyone
I know this is off-topic seeing as how it's about sendmail but I was
hoping someone could help out.
I have a machine with two ethernet cards in - previously these sat on
two different networks to take email from inside and deliver it to the
smarthost externally. Now that the network has been changed to 192.168
arrangement we don't need both ethernet connections, but I have noticed
a distinct delay on the other ethernet card to get a connection,
sometimes over a minute.
What is the second ethernet card connected to?
I assume that you havn't connected both network cards
to the same network (this will give an answer to your problems).
What is the output of ifconfig?

The next questions is, what's the output of "route"? Just a guess at
this point but sendmail may be trying to send on the NIC with the public
IP or do DNS look-ups. Either way, its going to time-out before it goes
to the 192.168 NIC. You may also need to check sendmail.cf to see if it
still has references to when the box had the public IP address.
Some things to try on your sendmail box:
1) route
2) dig any <smarthost>
3) dig any `hostname`
Cheers,
Dave
