sendmail in intranet

[Diego Pavón]

Hi.

I have one HPUX 11.00. This machine is in one intranet. I only know the proxy configuration but I can???t access to the mailserver. For this reason it is possible configure my sendmail to send and receive mail using the proxy configuration? I would like to send mail into Internet. Do I need some additional software to do this? Can I using POP3 or other protocol to send mail?.

Hi,

I need your name of your proxy software to plan the setup for your requirement.

Try this. In /etc/mail/sendmail.cf, look for the DS on a line by itself and type the name of the proxy server right next to the DS, no spaces. Then recycle sendmail and test.

#sendmail -v user@hostname.com
(return)
test
(return)
.
(return)

What is returned?

OK.

I did the following:

DSproxiserver # this is the name of proxy

I restarted my sendmail and do:

sendmail -v diego_pavon@yahoo.es and appear the following:

diego_pavon@yahoo.es... yahoo.es: Name server timeout
diego_pavon@yahoo.es... Transient parse error -- message queued for future delivery

In the /var/adm/syslog/mail.log I have lines like this:

Dec 11 15:19:44 CLLC_AC1 sendmail[9344]: PAA09344: to=diego.pavon@accenture.com, delay=00:00:27, mailer=relay, stat=queued

hi U.SivaKumar

The proxy software is NetApp and the HW is NetCache.

Hi,

Proxy will not relay the mail in that case. Better install unix in one machine and use the sendmail to relay mails from Internal machines to Internet

Setup will be like this.

public ip
(Internal)----|unixserver|---|Firewall|---(Internet)

use sendmail in the unixserver to relay mails from Internal network to Internet.

Put MX records in your DNS server pointing to
unixserver's public IP address ( interface connected to firewall )

open smtp port in firewall for unixserver both incoming and outgoing.
open DNS port in firewall for unixserver for outgoing only.
