I'm running a small IRCd on a vps. No firewall. When users register their nicks, a confirmation email is sent out to them by Sendmail to the email address they entered during registration. All but Gmail users get email. I found this and made an spf record using my IP address and placed it my MX record:
"v=spf1 ip4:168.235.75.84 include:_spf.google.com ~all"
But Gmail emails still aren't received. Here's some text from /var/mail/root

For what it's worth, I have an IPv6 address set up for my domain.
I'm out of my league on this and don't know what I'm doing wrong here? If I need to post more information, please advise. Thanks.
Your SPF record should include your IPv6 address.

I'm getting this bounce email only when sending to .de domains, can anyone point me on how to fix this ?
Are you getting this issues only from your account ? Please try to send test mail from free mail provider.(Gmail, Hotmail). I think recipient e-mail domain is not setup correctly and that is the reason you are getting this issues.
I find out my server is sending a spam. Spam is sent by postfix server. It has large queue of emails, that are going to be sent without my help. I cant understand which script is added these emails to postfix queue.
Now I have these questions:
How to determine what script is adding mails to postfix queue?
How to clear postfix queue from spam? (all emails are spam, there are no emails sent by me)

Googling gives no result.
My google search queries could be wrong, but I really need to fix this problem.
So any help is appreciated.
If I can provide more useful information please ask it in comments.
P.S. Server is hosting magento and wordpress sites.
P.S.S. 74.218.214.24 - is IP of my dedicated server, not original. It was changed in this post due to security reason.

It looks like one service or software triggering this mails. You can block all outgoing mails frompostfix by using the mail relaying options for external domains, this is possible if you don't want to send any mails from your machine.
You can check the maillog file inside /var/log - that will give the more details, also check the command mailq to see how many mails are pending.
Update:-
Do you allowed any of other people in your network to send mail through your machine ?, then you can suspect that case. Few things I can notice from the log is that -
The mail being rejected by the receiver end saying your public IP is flooding mails.
If these mails are coming periodically and not from any of other machines in your network, then you have to find out which process or application doing this. For that you have to use the tcpdump and monitor for the TCP packets. From that you can see that, the mail client first pushing the mail to your local postfix server, then that's being forwarded to the target mail server.
This is the way I can see to find out which application sending mails from your computer.
Hope this will help you to figure out the culprit.

I found the answer!
sendmail server uses Hostname setting and host setting
so make sure your setting is correct
/etc/hosts
/etc/sysconfig/network
and it works fine!
