Thumbs down Mails from my domain going to spam


Hi,
When we are sending mails, they are going to spam box of other account. We are using postfix. What might be the problem. Is my domain in any black list, if so how to check?

You can check your ip is whether blacklisted or not using the following links.

Also watch your mail log in /var/log/maillog, you will get some clues

Code:
Jun 26 01:57:19 plain postfix/smtp[7722]: D766569E5DE: to=<user@example.com>, relay=mail.example.com[xxx.xxx.xxx.xxx]:25, delay=8.9, delays=0.05/0/6.3/2.6, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as B940C72400C)
This is what i found in my /var/log/maillog. Mail has been sent, but it is reported as spam on the other end. I am not understanding what to do, What else to do?

Any way of checking how the other end classifies spam?? It will be in the mail headers on the other side.
Are you on a static ip?
Can you send mail anywhere else? Say to another of your own mail accounts?
Do you have a PTR record for the sending domain?
Does the PTR map to the forward address??

PHP Code:
Are you on a static ip?
Can you send mail anywhere else? Say to another of your own mail accounts?
Do 
you have a PTR record for the sending domain?
Does the PTR map to the forward address?? 
Yeh we are using static IP and it is a dedicated server. We have PTR record . This mail server is used to send mails. But any mails sent to this server will be redirected to google accounts.

You will need to check server logs and mail headers to see how the mail is being classified

ISPs hate spam as much as we do (it clogs up their bandwidth and their servers).

ISPs are getting smarter at detecting spam, and blocking it.

Sometimes they get a bit too smart. LQ was (incorrectly) blacklisted recently:
http://www.linuxquestions.org/questi...topped-729895/

You have some checking to do to determine exactly where the problem lies. The above link may help you, and centosboy has given you a good hint as to where to start.
