I having a problem sending email using sendmail running on CentOS 5.6. I get the message that the mail was sent, but it remains in the queue.

[root@localhost mail]# /usr/sbin/sendmail -v -qR mwhall@charter.net

I'm getting a message Deferred: 421 ... connection refused

Hi,

Maybe you need masquerading, to change localhost.localdomain to a real domain name. Many mailservers reject, or mark as spam mail from such domains,
