Is this your *outgoing* mail host?  mail.navigationbd.com with IP address of
202.53.168.75?

If so, it seems your server is being blocked from sending "spam".

The IP address of 202.53.168.75 blocked from sending to RoadRunner servers.  See
http://postmaster.rr.com/mail_blocks#directspam

hotmail is also rejecting mails from that server since it has too many addresses in
the RCPT commands of the SMTP protocol.  This is another indication of your system
sending out SPAM.

So, is your question....  What can I do to make my system send out SPAM in a better way?

Or, am I misreading what you think you are asking?

[Rafiqul Islam]

My question is too many unknown user sending mail using my MTA(Postfix) so
that hotmail,google reject mail from my domain(mail.navigation.com and
IP:202.53.168.75)  and i don't know how to stop this unexpected outgoing
mail.

I see....

In that case it sounds as if your MTA isn't properly configured to prevent "relaying".

I don't use Postfix, but maybe this link will help you to check your configuration to
prevent unauthorized relaying.  Also, it seems your host is being marked as sending
SPAM and that you'll have to request it to be dropped from the list of the various
organizations that have flagged your host.

http://www.postfix.org/SMTPD_ACCESS_README.html   may help....

Or, wait for someone that knows Postfix to give you a better answer.

ouch i did not see the "unknown user sending mail using my MTA"
shutdown you server NOW or at least make it unacessable
from the internet before you have a working mail-configuration

with this ip-address you are known as spammer and will not
be able the next time to provide any trustful mailservice

anybody out there must not open port 25 from the internet
becuase he was able to type "yum install postfix", that may
sound rude but nobody needs more spamservers maintained
by people missing the knowledge to maintain mailservices

to not be a open-relay is the first and most important basic task

From the other posts I take it your postfix server is not properly 
configured and is an open relay.

Steps to fix:

1) realize that your postfix mail server is an *open* relay (=BAD!). So 
you did not configure the postfix server in the proper way

2) stop your mail server right now

3) do NOT turn the mail server on until you know reasonably sure that 
you have fixed the problem. You can test your mailserver here: 
http://www.abuse.net/relay.html

4) go to postfix.org and read the documentation and properly configure 
your mail server to NOT be an open relay. If you can't find how to do it 
then read all the information again and again and perhaps use Google

5) if you can not figure out how to fix this problem then either hire a 
consultant who can fix it for you or ask on the postfix mailing list

I hope you realize that your IP address & domain may now be considered a 
spam origin in several spam block lists and that a lot of mail hosts 
will not accept mail from you even if you solve the open relay problem 
with your mail server.

Next time you want to activate a service it is probably a good idea to 
spend more time on understanding how the service works and what the 
proper configuration is...

Close incoming Port 25 and tell sendmail to accept mail only from 
127.0.0.0.  HTH, HAND.

First of all, he has already stated that he is using Postfix, not sendmail.

Second, you should not assume that closing port 25 is an option.   Indeed, if you
would do a little research you'd see....

[egreshko@meimei ~]$ host 202.53.168.75
75.168.53.202.in-addr.arpa domain name pointer mail.navigationbd.com.
[egreshko@meimei ~]$ host -t mx navigationbd.com
navigationbd.com mail is handled by 10 mail.navigationbd.com.

So, it would seem that this system is going to be accepting incoming mails from the
internet for at least one domain......  In that case it would be bad advice to simply
close port 25.

Patrick gave a nice summary as to the the step the OP needs to take.

In this case, one must indeed have opened port 25 manually, since "yum
install postfix" does not install any postfix configuration which has
port 25 opened by default.

Not if he uses smtpauth on port 587.  Granted, telling him only to 
accept mail from 127.0.0.0 was a tad excessive, but I was in the mood 
for a bit of overkill.  <snicker>

please do not advise people about topics you

Port 587 does not help you in the case of a MX
MX servers always needs Port 25 open but properly configured

i forgot the <sarcasm> tags

yes it is easy to remove the # in "master.cf" after "yum install"
but if this is all somebody does after install a MTA and make
him listening on WAN interfaces he should stop what ever doing
amnd reading many manuals before or outsource the task to
people knwong how to setup public mailservers

there is no single excuse for a open relay these days
not for a single second ona wan interface

public servers have to be tested and secured before
they see the first time internet connections and by
the hugeh damage open relays are doing all over the
world this is the most important rule for mailservices

I have, a few times, considered setting up a mailserver of my own for my 
domain so that even when I was away from home all mail went through it. 
  Every time I have, I've decided against it for exactly that reason. 
If more people did the same, we'd not have as many open relays spamming 
the world.

Setting up a mailserver is not a real problem, all the "big"
mailservers come with good documentation. However, they are complex
beasts, and "time" seems to be the real important factor. Getting
blacklisted because you build an open relay is stupid, but nothing
changes practice more and faster than adverse anecdote :-)

yes, time is the problem for most people

i built my first production mailserver with port 25 open
on WAN in 2009, started the implentation of a web-backend
and depending postfix/dovecot/dbmail-configs on a blank
machine and after two months i was finally sure that
this all is clean and secure enough to give it a public IP

and even after two months working day and night there were
enough troubles with clients relying on auth-mechs not
provided in the firt place after migrate some hundret mail
accounts with ariund 200.000 messages this time

so in my opinion if someone thinks "hey, i read some howtos
and in two weeks my server is production ready" he makes
a terrible mistake

this belongs to all types of servers, but no other type
can produce so much damage as a mailserver ina very short
time (excption: a webserver with php poorly configured
and with danergous scripts which can be used to bypass
attacks on 3rd oarty servers and generate spam via
unsafe forms)

if someone has not the time and willing to learn how to
deal with security and maintenance (not only for the first
setup) he should hire professionals who knows how to do so

Yup!  I'm retired, so time isn't the issue.  However, as there are only 
three people with email addresses at this domain there's no real reason 
for me to do it except personal satisfaction and if I've that much time 
on my hands, it's better spent finishing the final edit of my first 
novel[1] so that I can self-publish it and (maybe) get some extra 
income.  And, for that matter, I've gotten sendmail to use my hosting 
company's smtp server as a smarthost because my ISP blocks outgoing Port 
25, so even if I did set up my own server, my email would go from it to 
my hosting company and then get delivered.  Personally, I can't see much 
point to it.

[1]I have three novels from NaNoWriMo that I've finished and three 
sitting at somewhere over 50,000 words each that still need the first 
draft brought to a proper conclusion.  I'm going to get all of them out 
there, RSN...

Back in the day there was an outfit in Australia that would send you 
nasty griefing email if you had an open relay. Sendmail was JUST coming 
out with the means to prevent being an open relay, so there was a mad 
scramble to update quickly. And that was over 10 years ago. I agree, if 
you cannot comprehend email setup, best not to do it. I took a 5 day 
course in setting up sendmail and still failed the replay part of the 
final. So, I don't run a sendmail server today. <grins> Ric

This reminds me of something that happened over a dozen years ago, when 
I was doing tech support for an ISP.  I took a call from a man who 
wanted to know if he could use Windows Personal Webserver to host a 
website from his home computer.  Now, to me at least, the answer was 
obvious but it was also clear that if the caller had to ask, he probably 
wasn't ready to be doing it.  Instead of just answering his question, I 
tried to start out by advising him of the hazards involved.

"Don't tell me about what can go wrong," he told me.  "I can find that 
out for myself by doing it.  Just tell me if it's possible."

After a moment's thought, I did what was possibly the nastiest, cruelest 
thing I ever did as a tech support rep: I told him that he could do what 
he wanted, wished him a good day and ended the call.

You seem to have 0 knowledge of how server to server email works.  Please do some
work to understand what actually transpires before you advise people.

I'm talking about closing incoming connections from the Internet on Port 
25, not outbound.  Of course, depending on your ISP you might not be 
able to connect to other servers on Port 25 when sending mail, but 
that's not what I was referring to.

boah - unbelieveable
you still do not understand the topic

if you are runnaing an MX you MUST accept incoming port 25
from the internet or how do you imagine you receive new mails
from the world?

YOU MUST OPEN PORT 25
there is nof if and when

BUT you have to secure your configuration that you only
accept incoming mails for domains you are resposnible
and every relay needs authentication

and not, authentication is not limited to 587
you can configure every port for smtp/tls/sasl

If you're only running an SMTP server, that's not an issue.  If, and 
only if you're providing POP3 or IMAP, I'd agree with you.  In my case 
if I were to run a server, I'd only be using it for SMTP, as my hosting 
company does the rest.

wrong - your definition of server is broken
what you are speaking about is more a smtp-client

read postfix docs to get the difference between smtp_* and smtpd_*

jesus christ POP3 and IMAp has really nothing to do with
postfix and SMTP. really NOTHING

postfix doe snot speak any of them
postfix is a MTA

but the topic is not about your home machine
the topic is about a mailserver (the ones receive emails for their users)

please come back only to this thread after you realized how
email works at all (the whole life-cycle from MUA to Inbox)
including MX records/DNS

MUA -> MTA -> DNS -> MTA -> MDA -> Inbox -> Enduser

Wow, you *really* don't know anything about how to run an email *server* to service
*incoming* email for domains.  Please listen to Reindl, go study...then when you
think you understand, go study again.

Also study ESMTP, including the common capabilities of STARTTLS, ETRN, and PIPELINING.

Yes, but I was thinking in terms of an SMTP server, not a complete mail 
server.  That's why I was making the suggestions I did.  That doesn't 
mean that I was right, because I'm mature enough to know that everybody, 
including both of us, makes mistakes, it's an explanation of why I made 
the mistake I did.

Which is why I've no intention of running one.

It is an issue if it is a open mail relay.

Yes, I've known what an open relay is for at least fifteen years. 
That's why I suggested closing incoming Port 25 and using SMTPauth in 
the first place.  Please, try to keep up and avoid quoting people out of 
context.

And why it has been suggested that you refrain from trying to help those who are
setting up such servers.
