just 5 minutes ago i send mail from two mail boxes.from userid-1 i have recive mail in gmail inbox, and then i send mail from userid-02 .i goes to Gmail spam folder.i don't know the reason behind it.

And one thing more,when i try to restart the spamassion server i receive this error

/etc/init.d/spamassassin restart
Stopping spamd: [ OK ]
Starting spamd: [11546] info: config: failed to parse line, skipping, in "/etc/mail/spamassassin/local.cf": use_dcc 1

comments always go at the start of the line

so where you see use_dcc 1, change that to

#use_dcc 1

as for your spam issue; there are lots of things to check

1. Make sure you are on static IP
2. If you are using SPF, make sure the IP you send from is the same as in your SPF entry.
3. Make sure your server's reverse-IP lookup points back to your domain name
4. When sending mail, make sure the users authenticate themselves.

Hi

Sender Policy Framework (SPF) is a method that will tell the recipient mail server who is authorized to send mails from the sender domain.

It does this by adding a TXT record to your DNS entries. I suspect that if you are ignorant about this, that you have not set this up. This is fine, as absence of SPF does not automatically put you on any blacklist.

To check what domain your IP address points to, you can use this page: http://remote.12dt.com/lookup.php

As for users authenticating themselves, you'd have to dig into the postfix documentation.

Check following things !!!

1. Visit http://www.openspf.org/ for creating SPF record for your domain. Add this record as a TXT record in your DNS zone file, where other MX, A, CNAME records are specified.

2. For checking Reverse IP, visit http://www.dnsreport.com/. Or alternatively you can use dig and nslookup commnads for the same.

3. Visit http://www.senderbase.org to check whether your IP is blacklisted or not.

Refer below link for my older post on getting ride of spam and blacklisting.
