I get no responde, but when I SSH to my vps using putty and use

Code:

telnet localhost 25

I get welcome message

Code:

220 m5-fedora4-04.myxen.com ESMTP Postfix

and I was able to send test email to yahoo account as instructed in above link

You didn't set myhostname and mydomain !!
Will never work !

And did you forward port 25 from your router to your box ?

micko_escalade · #4 30th January 2006, 04:47 PM

thanks for the reply,
so lets say my domain name is linuxfan.com
how those lines should look?

Code:

myorigin = $myhostname
myorigin = $mydomain

my VPS is a remote machine somewhere in the U.S.A
when I use tihis small app (angry ip) that scans ip for open ports and looks like port 25 is open
http://img81.imageshack.us/img81/4206/angry1yc.jpg

but when I use this site to scan for open port it says no service running on port 25 link

foobar47 · #5 31st January 2006, 09:04 AM

myhostname = mymailbox.linuxfan.com
mydomain = linuxfan.com
mynetworks = 10.1.11.0/24, 127.0.0.0/8 #depends on your network
myorigin = $mydomain
inet_interfaces = $myhostname, localhost

Did you forward the port 25 and 110 to your mail box ??

Actually, the ip you try to telnet use PHP 5 and the domain name have the Fedora Core Test Page available...

So i think you try to telnet a box which don't correspond !

Did you have a router ??

Edit : Hey man, have a look to your last link :

Quote:

The host 207.210.228.xx has a service running on port 25 (smtp).

Where is the problem ?

When i try to telent your domain name :

Code:

telnet garaxxx 25

here is the result :

Code:

220 m5-fedora4-04.myxen.com ESMTP Postfix

When i try to telnet to the ip :

Code:

telnet 207.210.228.xx 25

here is the result :

Code:

220 m5-fedora4-04.myxen.com ESMTP Postfix

Everything seems to be OK !!!

No ?

also you may be on a blackholed isp

add

relayhost = your ISP's smtp-server

I did change it but still can't send

I wasn't sure about this one,
my VPS (virtual private server) is remote machine in texas, not home network

I can recive now, so I don't think port is blocked

Quote:

telnet garaxxx 25

why I wasn't able to telnet was because APTR recordes didn't propagate at that time,
but when you tried they already did

this is error log from /var/log/maillog every time I try to send email

and the other thing that I don't understand is
before I didn't put m5-fedora4-04.myxen.com in local-host-names file in postfix
when I would send test email from yahoo, I would get instant bounce from my domain,
myxen.com is my host domain (I mean where my VPS is) and ip is different then my VPS ip,

I don't know if I should change it to one of my virtual domains ??

Code:

[root@m5-fedora4-04 ~]# hostname -f
m5-fedora4-04.myxen.com

Code:

[root@m5-fedora4-04 ~]# hostname
m5-fedora4-04

You should know what is your local ip network !!

Yeah, it takes about 24h to propagate...

Quote:

m5-fedora4-04.myxen.com

I recommand you to put a the domain linuxfan.com and not myxen.com...

Imagine you put mymailbox.microsoft.com and you send mail with it... do you think it can be possible than other received mail from a box microsoft.com which is not one ?

You should put the exact domain name !

Sorry for my poor english

Cheers

I added those lines to main.cf

Code:

smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated,reject_unauth_destination
smtpd_sasl_auth_enable=yes
smtpd_sasl_security_options = noanonymous
broken_sasl_auth_clients=yes

in /etc/postfix directory did

Code:

mkdir sasl
chown root:root sasl/
chmod 755 sasl/
cd sasl

then created smtpd.conf with this in it

Code:

pwcheck_method: saslauthd
mech_list: digest-md5 cram-md5 plain login
log_level: 3

then run this

Code:

chmod 644 smtpd.conf
chown root:root smtpd.conf

finally that error went away (when trying to send emails), but then re-login box keeps popping up and still can't send

I know I have right username and password because I use same to send/receive in SquirrelMail
