Re: [Devil-Linux-discuss] [BULK] SMTP

Hi,

is the exchange server in LAN A? If so, i'd guess that the exchange server =
has=20
a wrong (short) netmask... In any case, run=20
tcpdump -i <name of the LAN interface> host <exch server>
on the DL closest to the exchange server. Then try the telnet form remote a=
nd=20
see what happens.=20
You could have netmask problems on the client side also, of course...
but we need more info to tell for sure.=20
Hth,
