Hello All,

I wish to set up my home pc to retrieve mail from my local Internet
Service Provider, I am using Linux and I know little about how to do
this. My ISP uses PoP3 protocol and I tried to set up my sendmail.cf 
file by replacing it with one that was supposed to work.When I ran my
script to start sendmail and popclient, my screen was filled with 
error messages refering to the sendmail.cf file?
I know I have not given very specific infomation but could someone
point me in the right direction to get things up and running.

Thanks in advance,   Richard Ashton. mailto:[email-masked]

Hi!

Is there a reason you want to use POP services _and_ sendmail?  I must
assume that you are not online 24x7 and need a place to store your
mail while you are not online.

A POP3 client is used to get mail from a POP3 server (daemon) on the
mail server where you messages are stored.  Presumably on your ISP's
E-mail server.  Sendmail simply allows you to keep your mail account
on your local machine by having the ISP's E-mail server route mail
directly to your sendmail daemon.

It seems you are trying to mold the two together . . . Why??
Why would you want to mix the two??

Perhaps you should go strictly POP3 and take sendmail out of your rc.M
file.  That will make sure that it does not come up when rebooting your
system.

On the other hand, you may want to get rid of the POP client and go
strictly sendmail.  This assumes that you are online 24x7 (like me) and
can accept mail at any time.  If not, talk with you ISP to get
alternatives.

The following is my sendmail config.  Modify the Cw line for your own
fully qualified domain name and or your own domain (like I have).  Also,
make sure your ISP have these things configures in their sendmail.cf and
in their DNS:
