Denied due to spam list.

Hi
I am having an issue with unknown user bounce message, I have read the other post relating to this issue but the solutions do not to work, so unless I am missing something I am really stuck.

Whenever I send a message to unknow@mydomain.com I am expecting back a bounce like;

Hi Maria!

Did you restart smtpd using the commands below, if not do it now:

Code: Select all

omoff -wd 0 smtpd
omon smtpd

If you search this forum for "Denied due to spam list" you could find so many solutions, see
if it helps.

Thanks,
Subir

sounds a little unclear.....

is "myscalixserver.com" and "mydomain.com" one and the same?

are you using outlook or imap to send? if its outlook it should work, swa should also work. If its imap you need appropriate RELAY lines in smtpd.cfg

The error actually says YOU, or "unknown@mydomain.com" do not exist. This is usually due to a lack of a "RELAY accept mydomain.com" line in smtpd.cfg when you are using imap.

Make sure your smtpd.cfg is correct.

I have restarted the smtpd using omoff ... and omon. As I ahve allready mentioned I have been all theposts containing the words 'Denied due to spam list' I have still have not got anywhere hence posting this message.
But thanks for the response.

Thank you for the reply, when i say myScalixServer.com I am referring to the hostname of the server on the internal network. And myDomain.com is the domain to which the MX ties.

Curiously when I use the Scalix Web Access and send a message to an unknown users, I get no bounce message returned. Although when I send a mesage to an unknown user from my ntl email account I get the same 'Denied due to spam list' message returned.

As for which client, I am currently using Evolution 2.8 with Centos 5 with the Scalix Connector installed.

You said I must ensure that the smtpd/cfg file is correct, as Reverse DNS is not configured for this domain, surely all I would need in that file is the IP addresses?

All I want is for the unknown user bounce message to return Unknown User, instead of this 'Denied due to spam list' error.

you will definitely need

RELAY accept mydomain.com

in your smtpd.cfg. Restart smtpd after adding that and you'll get around the error.

It depends on the email client as to wheter you need to relay accept from hostnames or ip addresses or domain names. The connector uses domain names, imap uses ip addresses. SWA is completely different.

However you just opened up a can of worms for me...could be something i've configured on my system, but when i sent an email from scalix connect for outlook to aduduser@les-domain.com it actually got forwarded out via my smart host (to upstream isp smtp server), then back, then out, then back...etc...until it got too many hops and died in postmasters arms. It should have rejected straight away....go figure. I'll check that one out.

From what I have read so far, the output of hostname --fqdn should be in the smtpd.cfg file, I have also found that if I have incorrect entries in the smtpd file then of it goes hopping round and eventually replies with to many hops.

I am currently going for the trail and error approach,

I have noticed this in the return message, (bold and enlarged) Not sure if the . is causing or at least contributing to this error. I did read in another post that a . did at least contribute to this error but the solution there did not work in my case.

Do any of the scalix guys have any other idea's I feel like I am going in circles and getting no-where. This error is halting the rollout of the product.

I posted another topic because by investigating your issue i found another one.
viewtopic.php?t=7254&start=0&postdays=0&postorder=asc&highlight=


I just did a fresh install on a new machine. Default out of the box smtpd.cfg looks like...

# NB Authenticated RELAYs are always allowed
RELAY accept 127.0.0.1
RELAY accept .mydomain.com
RELAY Log_Reject ALL

# extra rules added to prevent open relay usage
RECIPIENT Log_Reject *@*@*
RECIPIENT Log_Reject *%*
RECIPIENT Log_Reject *!*
RECIPIENT Log_Reject *#*@*

...i have not heard of needing hostname --fqdn (which in my case would be mail.mydomain.com) in smtpd.cfg, and i never use it on any of my sites.
I always just leave the default as above, and if i need to do imap i relay allow the ip address range.

Where did you read that? in the docs? forum?

[mia]

I read that in one of the many psosts referring to this error.

thats not a problem. that's standard format.

Have you modified the smtpd.cfg and tested as i suggested?

i.e. please try this in your smtpd.cfg....

RELAY accept .mydomain.com

make sure you have a "." before your domain name. You can only stop going in circles if you try other things.

I have found a resolution to my other problem, and it will probably help you if you haven't got it already....

in order for sendmail to properly reject unknown internal users you will need your domain added to the /etc/mail/local-host-names

restart sendmail afterwards.

Hi Les
Thank you for your time on this;

Ok, I added the preceeding '.' to my domains in smtpd.cfg and after sending a test unknown user email some 10 inutes ago I suspect it has gone off to hop 25 times before failing.

Would you mind If I PM'd you my local-host-names file contents and also the smtpd.cfg file.

I had the domain names in local-host-names and I am still getting the error, It is extremely fustrating when you know it is somehting you have or have not done.
