Allen,
You said you have tried various masquerade but have you tried masqyerade as suggested by Greg?
MASQUERADE_AS(`my_domain.net')dnl
Just curious.

Hi Allen,
?
I believe you need to ask your ISP to add a DNS MX record for system.house.network.
?
Why don't you just change house.network to one of your registered domain? The reason it work is because BigDaddy.com created DNS MX records for those domains.
?
Hope it will help.

Hello:
? ? ? ? I need to know exactly what options need to be specified in
sendmail.mc to generate the proper sendmail.cf file so the domain name
my ISP sees is valid.
? ? ? ? Here is some information why this is needed. I have 2 Windows PC
and 1 Linux systems and several Home Automation, NAS, Media systems on a
home network. I have named running on the Linux system for a local
fictional domain called "house.network". I know network is longer than
the normal 3 character .com, .net, ..., but it works with no problems as
far as name lookup and what have you. I also chose the longer name so
there would be no conflict with a real domain name out in the real world
and thing on my local network would not get routed to it. I have some of
the special systems send email to the Linux system which then has
aliases to send certain emails to my ISP email and/or my work email.
This is where the problem starts.
? ? ? ? If the Linux host name is set to system. house.network, then
when it connects to the ISP I get error 550 Invalid sender domain. This
is because the domain cannot be looked up by the ISP and I can
understand why. If I set the Linux host name to system.my_domain.net it
works like it should. I registered 2 real domain names (my_domain.com
and my_domain.net) with BigDaddy.com partly for this. But when the Linux
host name is not in the same domain as the other systems on my local
network it cause some other problem.
? ? ? ? If I add the option in sendmail.mc to generate a sendmail.cf
file with Djmy_domain.net and have the Linux host name set to
system.house.network the ISP complains with basically the same 550
error. Looking at the returned email some of the header information
looks like:
Reporting-MTA: dns; my_domain.net
Received-From-MTA: DNS; system.house.network
Which indicates to me the value of the host name is what my ISP sees
that it tries to validate. I have looked at and tried various
configurations for masquerading, but have the same problem. It seems to
rewrite certain header entries that basically the user's client software
look at to display from and to and what have you, but does not change
the Received-From-MTA entry.
? ? ? ? So I hope someone has some good suggestions to help me resolve
this problem.

Thanks for the reply, but my ISP is NOT going to add anything to their DNS for my system. I am just one hundreds of thousands that get a dynamic IP address from them. The point of my question is to find suggestions on how to configure sendmail to work with an ISP that is not going to change anything, but validates the systems that connects to them to relay email. This is done to eliminate SPAMER.

Thanks for the reply.
I have already tried that and it does not work. When my system connects to the Comcast email server is tells it it's real name and the masqueraded name. Comcast tries to look up the real name which it cannot find and then refuses to relay the email. It returns the email stating it is an invalid domain.

Hi all,
I have a nfs server that I use to store my backups and in the client machine
I get a lot of messages like these:
Aug 31 09:03:47 SERVER kernel: nfs: server 192.168.1.111 not responding,
still trying
Aug 31 09:03:47 SERVER kernel: nfs: server 192.168.1.111 not responding,
still trying
Aug 31 09:03:48 SERVER kernel: nfs: server 192.168.1.111 not responding,
still trying
Aug 31 09:03:51 SERVER kernel: nfs: server 192.168.1.111 OK
I have mounted the export this way:
192.168.1.111:/nas/NASDisk-00002/share on /backup type nfs
(rw,noatime,noacl,rsize=8192,wsize=8192,hard,timeo=10,intr,addr=192.168.1.111)
which can be the problem? Is there any problem with de mount options?
I have tried with the soft option but with this option the server gives the
error and the backup process stops. (which is worse)
any idea?
Thank in advance

ESG,
That message simply implies that the client is unable to reach the NFS
server for some reason. This could be because of a network issue or a issue
on the NFS server side. What do the logs show on the server side? Also, it
may be useful to check this in realtime when the issue occurs from both the
client and the server to get a better assessment of the issue. - Dustin
