[ISPConfig] Can't send and recieve emails

[name]

Hello,

I have installed ISPConfig and it seems like everything is working.

But I can't send (and receive) mails.

//edit: Update: now I actually CAN recieve mails (the problem was that I had added the line: home_maildir = Maildir/ in the main.cf, while ISPConfig has to manage it, so after deleting this line it works... Nevertheless, I can't send mails, although it works with the webmailer(!). Look at some of the newer posts if you want to see what has been done. thx

I tried:
telnet MYSERVER 25
220 MYSERVER ESMTP Postfix (Debian/GNU)
mail from:test@MYSERVER.tld
250 2.1.0 Ok
rcpt to:mail@domain.tld
554 5.7.1 <mail@domail.tld>: Relay access denied

I also cant recieve mails.

Here is postconf -n:

The mail.err doesn't show up any errors...

Perhaps someone can help me? Would be really great!!

Just testet the following:

telnet LOCALHOST(!) 25
helo localhost
.......

and send a mail just by connecting to the server via localhost instead of using the "gloabal" server-domainname.

This actually works and I get a mail with the correct sender (something@mydomain.tld).

Perhaps this is a clue?

thx,

Can the problem be, that my Servers IP is missing a Reverse DNS Entry?

Perhaps this would explain that it SENDS mails when connecting to "localhost" via telnet, but won't send mails (Relaya acces denied for any mail-adress I want to send a mail to) when connecting to the IP or Domain name?!


Hope someone can help me

Try an email client like Outlook or Thunderbird and make sure that you enable "Server requires authentication".

hi,

no I also can't send mails with thunderbird. It is just saying:
"The SMTP-Server isn't available or is refusing the connection"...

What I have tried so far:

Successfully sending a mail to mail@address.de via telnet localhost 25:
server:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 server.example.de ESMTP Postfix (Debian/GNU)
helo localhost
250 server.example.de
mail from:test@example.de
250 2.1.0 Ok
rcpt to:email@addresse.de
250 2.1.5 Ok
data
354 End data with <CR><LF>.<CR><LF>
subject:testmail
test
.
250 2.0.0 Ok: queued as 8E97E2C234
quit
221 2.0.0 Bye
Connection closed by foreign host.


But when I try to connect to my address server.example.de nothing happens:
server:~# telnet server.example.de 25
Trying 0.0.0.0... (0.0.0.0 ist natürlich in Wirklichkeit die korrekte IP)
helo server.example.de

And it is just like halted....


Sending a mail from mail@address.de to web7test@server.example.de doesn't work and I get the following error MSG:
Reporting-MTA: dns; server.example.de
X-Postfix-Queue-ID: 25F252C235
X-Postfix-Sender: rfc822; email@addresse.de

Original-Recipient: rfc822;web7test@server.example.de

Nevertheless i CAN connect to my Server via POP3 and IMAP, so when I place a "fake-mail-file" in the Maildir of mr. web7test in /var/www/web7/usr/web7user/Maildir/new/ it DOES show up in Thunderbird(!)


I even can't send mails to myself in my network:
server:~# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 server.example.de ESMTP Postfix (Debian/GNU)

Verifying to see if web7user exist is possitive:
mache ich ein verify erscheint folgendes:
vrfy web7test
252 2.0.0 web7test


Here is the maillog after sending a mail from myself via telnet localhost 25 to myself web7user@server.example.de:

Actually I forgot to post my /etc/postfix/local-host-names last time:

I have made a little change in the main.cf and just REMOVED the last line saying home_mailbox = Maildir/
because actually I want ISPConfig/Procmail to make all this with Maildir and now I can RECIEVE(!) Mails, but I cant send...


Thx for reading(!), as said the problem still is, that I can't SEND mails

Name

[name]

Ok,

I hope this is the last "update" before everything works as it should

Because when I use the ISPConfig-Webmailer, it sends the mails as it should!!!


Nevertheless I cant get Thunderbird (and probably also Outlook, etc.) to work.

I have tried to send WITHOUT tls, WITH tls when its AVAILABLE, WITH tls and WITH ssl, everything brings up the same error-msg, that the SMTP either isn't available or refuses the connection.....

Perhaps this brings enough light into the darkness?

Hope so...

thx,

[till]

Please post the output of the command:

iptables -L

[name]

The output of "iptables -L":

server:~# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination


There is really nothing, I don't think this is good?

Hi again,

my it be, that although you can see there is no rule for the firewall, it is impossible to connect to the SMTP-Server of postfix from the OUTSIDE (you know, if it isn't a connection from localhost to localhost)?

Because as said, I even can't connect to server.example.de with telnet (wich isn't bad).
But if it is also impossible to get a connection to server.example.de's SMTP from e.g. Thunderbird, that would be a problem.

I don't know how to check it and I even don't know where to change the configs (of postfix) to accept "OUTSIDE" SMTP-Connections.


Perhaps someone can help me?

Thx

[name]

Also it seems like noone can really help me and I don't want to "spam" too much, I have decided to give you a bit more info.


I now can login via telnet to my domain:

This mail does also arrive at my@ddress.de....

So why I can't connect to the SMTP via Thunderbord, Sylpheed Claws, etc...(!!!!!!!)???

Please please help

Does it just have something to do with the mail-clients setting or something else wrong?!


OK, i think the problem was, that thunderbird etc. was blocked by my pc :S

thx
