I am having a few problems with configuring Sendmail on a fresh install of CentOS 5.6 32Bit and was after some help.
I have a couple of CentOS boxes installed and want them to send Emails to my domain account via our existing internal Lotus Domino SMTP server. I have followed a lot of online documents about how to configure this (such as http://cri.ch/linux/docs/sk0009.html
) but when I try am not even getting anything in my SMTP servers logs for a connection.
What I have basically done is uncomment the following:
and added the IP address of my SMTP server (have tried FQDN as well). The SMTP server doesn't require authentication so I assume I don't need to do anything else than above. I have then completed the following:
m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
and then restarted sendmail. When I then try "sendmail -bv firstname.lastname@example.org
" I get the following:
... deliverable: mailer relay, host 172.29.1.76, user email@example.com
which looks hopeful. However, now when I run "sendmail firstname.lastname@example.org
" I don't get anything delivered. I have telnet'd (on port 25) into the SMTP server with no problems from the CentOS box so it isn't an access issue.
