Subject: RE: [brluglist] Smtp connection
Hot diggity dog! I had all the options but the -H, once I added that option
it worked fine. Can you explain to me what that -H option does, or point me
out to where I can find further information on it?
Thank you.
Chuck

Also if you are starting with TCPSERVER - check and see if you have -R -H -l
0 in your options. That turns of reverse lookup and self lookup.

Sounds like you're having a problem with reverse DNS. Make sure the
computer can do reverse lookups on IP addresses, and make any necessary
corrections to the nameserver entries in /etc/resolv.conf. If they're
all internal PC trying to connect, and they don't have real internet
hostnames, you may consider adding them to /etc/hosts.
