CentOS sendmail


Hi,

1.I have configured a Sendmail on my local server, created 2 domains at /etc/mail/local-host-names

2.created 4 users for eg: testuser1@xxxx.com and user1@yyyy.com
both users able to send emails from each other

3. Issue1: one of user unable to receive the emails - 3rd user, but able to send.

4. Issue2: whenever I send emails to any users I am getting a copy into root- Y?

5. Now I want to send emails to another domain for eg: mail.google.com

for this what are the prerequisites I should have?

for your Info, I have a DNS server with Public IP, created A, MX records I don't know the creation is correct or not..!!

6. I want to forward all emails to one email account, is it possible if yes- How?

3. Check the logs (usually /var/log/maillog)

4. Read this or this

5 If your public IP is resolved to a valid hostname, most likely you can send out mail. You can check your MX record here
If you can't send mail, then most likely your ISP is blocking outbound traffic to port 25. In this case maybe you'll need to use their smtp as a smarthost

6. See #4 above
