Topic: mail from outside (user unknown)

[Michiel de Jager]

Hello,

I have a problem when sending mail to my server.
When I sent mail from a pc within the same network to the server there's no problem.
But when I sent a message from an other pc on the internet to my sme-server
I get the following error in a return mail to the sending computer.

 ----- The following addresses had permanent fatal errors -----


   ----- Transcript of session follows -----
... while talking to madern.mine.nu.:
>>> RCPT To:
<<< 553 Requested action not taken: mailbox name not allowed
550 ... User unknown


What can I do about this?

[robert]

Try sending to michiel@mine.nu or even michiel@mail.mine.nu

[Michiel de Jager]

But my domain name is madern.mine.nu
the sever name is webmail

so complete name of server is webmail.madern.mine.nu

but when i sent to that address I get a message that the host doesn't exist.

[Bob]

Shouldn't you send it to michiel.de.jager@madern.mine.nu?

Because in SME/E-Smith your username is michiel, but usually your email
address is FIRSTNAME.LASTNAME@DOMAIN_NAME.

[Michiel de Jager]

When I sent from a pc within the internal network it works, so the mailaddress is good.

The name on the mailbox is "username" as well. SME automatically sets up pseudonyms for firstname.lastname and firstname_lastname, which forward to the username. Just FYI...

[Michiel de Jager]

Nope

Could it be a DNS issue? Maybe the server mail is getting directed to from outside is at your ISP or something, but internally it's resolving it ok? Just guessing here.

[Tom Carroll]

Are you using pop3 mail or doing this through the webmail panel?

[Ruusvuu]

In order for my users to be able to SEND mail through my server via OE or something - not webmail/IMP - I need to add their IP as a local network.  They can receive ok without this, but they con only SEND if they are listed as a local network.

You should check out Nathan Fowlers pop-before-smtp.  It may be what you are looking for.

There is a pretty good thread about it's security here:

Hello Guys,

SENDING MAIL IS NO PROBLEM.
The problem is that I can't receive any mail from the internet.
And it isn't a DNS problem.

Maybe this helps?
This is the connection to my mailserver.
As you can see, the connection is oke, but the mail can't be send.
When I try it from a pc within my network I have no problem.

Please help me, I ran out of ideas.

Maybe interesting;

I am behind a router and a firewall.
I use NAT to translate my local ip to a public ip.
All required ports are open (pop,http,https,smtp)

Looks similar to the problem I and a number of others have queried. Appears to be a problem with 5.1.2. SME sometimes will accept mail and sometimes won't. I can get 3 e-mails in a row with identical addresses and one is bounced.

I have basically given up on SME for mail and am currently building a sendmail based mail server. I know that will work.

Regards
kevin

[Michiel de Jager]

Well,

It isn't the same problem, for I have it with 5.1.2 and with 5.5b9
and it hasn't worked one time.

Tom!

I did this - everything seemed to go as outlined.
I don't know what's going on for some folks, but I do not have a problem that I know of.

[Nathan Fowler]

I have seen issues where the smtpd_check_rules file was corrupt and it did cause some odd behavior.  If you are willing to send /var/spool/smtpd/etc/smtpd_check_rules I could look it over and hopefully isolate the problem.

Hope this helped,
Nathan

[Michiel de Jager]

But I don't have such a file, I have just a basic e-smith installation.

If you don't have the file /var/spool/smtpd/etc/smtpd_check_rules then that would be why you are unable to receive incoming mail.

[Michiel de Jager]

How can I fix this?

I also dont have the smtpd/etc/ directory in my var/spool directory

[Dan Brown]

Yes, you do have such a file, it's part of the basic installation.

[Nathan Fowler]

/sbin/e-smith/expand-template /var/spool/smtpd/etc/smtpd_check_rules

ls -la /var/spool/smtpd/etc/|grep smtpd_check_rules

And, yes Dan is correct, this is part of the default installation and you should have this file.

[Michiel de Jager]

I have installed it on two machines, several times, and never had that file.

I also have a pc where I have no problems and there isn't the file either

When I do that I get the message: no templates where found for ........

I think I don't need this file at all

If you want your SMTPD to receive incoming mail, you need this file.  If you don't have this file, you have either a buggy installation of E-Smith, or you have deleted the template directory or the file itself.

What version of E-Smith do you have?  I recommend you reinstall...

[Michiel de Jager]

At he moment I am running 5.5b9 but a have the same with 5.1.2

[Nathan Fowler]

I have no idea why you don't have this file, you should.  I'm 4.1.2 and I have this file.  5.5 folks have this file as well.  Not having this file is your problem.

[Michiel de Jager]

I must call it a day today, I'll mail again tomorrow.
Have a nice day.

Then ignore what others have said about requiring smtpd_check_rules as this beta doesn't include obtuse smtpd. Instead try and gather as much info as you can and potentially post a bug report to Mitel. If your going to run a beta ensure you read the release notes and change logs. I can't seem to find a page on the Mitel development site that lists changes between releases and betas, you'd assume it exists right?

I wouldn't be so quick to dismiss the possiblity that it's an MX issue. The only extract I saw was a client session, which may or may not have actually been on your e-smith server. Post the corresponding session logs from your server.

I did some tests again and found that it works great at home on a laptop, but the same laptop didn't recieve mail at work.
The only difference is that at home I use a standard ADSL line with a draytek vigor2200E router.
And at work we have a bigger adsl line with 16-IP-Addresses.
And At home I have to use a mailrelay server from my provider, and at work I don't.
I Have redirected the following ports "smtp-pop-http-https" and as you can see there is communication between the sender and the sme-server.

Maybe this is helpfull to somebody?

Problem solved,

It was my watchguard firebox that stopped the mail from entering my domain.

Thanks for all your help.
