Hello, I am new user of the Sendmail on RH 8.0. I am trying to configure the Sendmail on my Linux Laptop to send mails over LAN using SMTP and use the LAN server to route mails and receive mails over the internet. I have read the instructions in the Linux System Administrator's guide and did some changes in the sendmail.mc file and then using the m4 macro processor created a new sendmail.cf file. After this I tried to send mail to myself, that is to root, I checked response by looking at the -v options response. It always says thta connecting to the LAN server (mladelhi.mine) root... Connecting to mladelhi.mine.nu. via relay... root... Deferred: Connection refused by mladelhi.mine.nu.
I am not getting the normal message of message delivered. What should be the change in configuration for atleast make it work for local delivery atleast? Please help me in this regards,

Do you have a local mailer set up in your sendmail.mc? Also, have you stated which hosts are local (in Cw or sendmail.cw?)
Thanks for the quick response. Well, I think I have the local mailer setup. I am sending you my sendmail.mc file
# Following is my sendmail.mc file
divert(-1) dnl This is the sendmail macro config file.

Please do not Cc me on replies. Also, put your reply *below*, or interleaved with the original post (see how I do it), not above it. It took me 2 minutes to figure out why this mail was in my inbox.
FEATURE(use_cw_file)dnl
This will use sendmail.cw
Cwlocalhost.localdomain
So you can put additional entries there.
I think the Cw sets it to the localhost.
You'll also have to add all aliases (localhost, any other host name that you have for it, etc.)
