[rhn-users] My sendmail could not send email

[John Paul C. Orpilla]

I was setting up a local mailserver to get all messages from
mail.amellar.com using RHEL 4 AS, sendmail-8.13.1-2, dovecot-0.99.11-2.EL4.1,
fetchmail-5.9.0-1. Im using outlook express as mail client I have no problem
popping all the messages from the remote mail server but when I used outlook
express to send email to yahoo or gmail all the emails went to bulk or spam
while the others cannot be send.  I had read the knowledgebase and googled
but still unsuccessful here are my configuration.

Dovecot.conf

protocols = pop3
imap_listen = [::]
pop3_listen = [::]
login_dir = /var/run/dovecot-login
login = imap
login = pop3
mbox_locks = fcntl
auth = default
auth_mechanisms = plain
auth_userdb = passwd
auth_passdb = pam
auth_user = root
