echo prueba |sendmail -v amezquita.erick@bellsouth.com.gt
amezquita.erick@bellsouth.com.gt... bellsouth.com.gt: Name server timeout

Eric:

If you are using your Exchange server to route outgoing email (aka "Smart relay host") from your system, go into /etc/sendmail.cf and edit the 'DS' parameter to include the host name of your Exchange server. For example, if the /etc/hosts entry for the exchange server is:

192.168.4.4 mailserver

Change

DS

to:

DSmailserver

in /etc/sendmail.cf and restart your sendmail process. All emails not going to your local system will automatically be routed to the Exchange server for delivery.

I hope this helps,

Sendmail relies on DNS - make sure your /etc/resolv.conf file is configured correctly and that it points to a DNS server that "knows" about bellsouth.com.gt or has a forwarders statement configured.

If the machine you want to mail to is loacl, then yes, set your DS macro to the server name of the exchange server. You might also need to set the DM macro to bellsouth.com.gt

Does the message go out later?

If you are running 8.11.1, first make sure you have the latest web download installed. If so, and you still have the problem, then increase the timeout parameter in the .cf file:

#O Timeout.resolver.retrans=5s

change this to something like 5000 ( this is in miliseconds), uncomment, restart the sendmail daemon and see if that works.

If the message never goes out.

It's DNS or mail relay server.

nslookup yahoo.com

Does it resolve. If not, check /etc/nsswitch.conf how resolution occurrs, then /etc/resolv.conf to see if those entries are actually name servers.

If you are already using the DS parameter noted earlier in the thread it could be your mail relay server rejecting your mail.

Usually those servers authorize relay one IP at a time and the admin needs to do that.

Diagnostic test:
/usr/sbin/sendmail -v -d8.99 -d38.99 stevenprotter@juf.org

Replace my email address with a real one please.

after using the command line, type a line of text and then

Then a dot(period) . the

You'll get plenty of diagnostics and go down the right road toward resolution.
