Denied due to spam list 550

[erancx]

Hey guys,

I installed Scalix yasterday on CentOS server 4.5.
everything is working perfect except I cannot send an email through outlook.
As you probably guess, I get
"Denied due to spam list 550"

I searched in the forum for the problem,

my smtpd.cfg contains:

Code: Select all

AUTH_SUCCESS Accept ALL
RELAY accept 127.0.0.1
RELAY accept .domain.com
RELAY Log_Reject ALL

RECIPIENT Log_Reject *@*@*
RECIPIENT Log_Reject *%*
RECIPIENT Log_Reject *!*
RECIPIENT Log_Reject *#*@*


I restarted smtpd with:

Code: Select all

omoff -d0 -w smtpd
omon -w smtpd


and I enabled 'My server requires autehentication'.

and when I telnet localhost 25 everything is working good.

Code: Select all

[root@zmail ~]# telnet localhost 25

What am I doing wrong?

Do your tests telnetting ip address of server instead of 127.0.0.1 (localhost).
You should receive a welcome message like : ESMTP Scalix

194.90.256.256 ???
194.90.257.257 ???

Have you masquerade the IP addresses or these are the real ones ? If the latter there is something wrong.

[erancx]

no dude,

I changed it..

[BaldBoy]

When you say "I can't send emails from Outlook" you need to clarify: have you installed Outlook Connector for Scalix or are you using Outlook as an IMAP client ? If the latter have you enabled SMTP authentication on Outlook ? Are you using the right credentials ?

More ...

Code: Select all

RELAY accept .domain.com


Is .domain.com the domain associated to your *local* network ? Or is it your email domain ? That row should report your localdomain as that rule means "accept and relay every email coming from computers bound to <domain>".

Looking at your logs I can see "localhost" is bound to "localdomain": therefore RELAY rule in smtpd.cfg should report localdomain as an acceptable source.

If you're not sure about which is your "local" domain try replacing that rule with:

Code: Select all

RELAY accept 192.168.0.0/255.255.255.0


assuming you'r local network is a C class for 192.168.0

Always restart service after this change.

[erancx]

ah!

I didn't know about that Outlook Connector.
It's working great now!


thanks buddy!

I would however urge you to make sure understand what baldboy has been telling you about the relay controls in smtpd.cfg & check & test your config from other clients also.

It'll bite you some other time if not.

Hi,

Do you have a Cisco firewall? I ask because of the **** in the banner, instead of the Scalix. If so, and you have SMTP/ESMTP inspection on in the firewall, it breaks SMTP authentication (especially in pre 7.0 releases of the firewall). I always turn this feature off, in 7.0 plus it is called ESMTP inspection, in pre 7.0 it is called fixupprotocol.

Hi We have also encountered that problem with Outlook. What we did is
you open your outlook then go to Tools->Email Accounts->View or Change existing email account. then Click "Change" . then click the "More Settings" button the Organization and Reply Email should be filled up.
