Hi
Sendmail will do a reverse DNS lookup for the IP address of the
connection to put the name in the logs. Apparently this
doesn't work for the address you are testing from and you
wait for a timeout. Perhaps the delegated DNS server is
blocked by a firewall that drops the packets. Likewise there
is an IDENT query for the owner of the socket, but those
timeouts are usually faster.
It seems to happen with *everyone* who tries to connect outside of the
LAN.
Not from here it doesn't:

I have working reverse DNS though.
Paul.
I wind up putting the hosts into /etc/hosts, and that usually resolves
things with sendmail. HTH.
