Cant telnet to local host - ISPConfig 3

[zogthegreat]

Hi everyone,

Seems I have another problem with ISPConfig 3.

When I try to telnet to local host, after about a 5 min pause, I get the following:

[root@server1 ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 server1.example.com ESMTP Postfix
421 4.4.2 server1.example.com Error: timeout exceeded
Connection closed by foreign host.

The same when I try form another machine:

[bill@phoenix~]# telnet 70.XXX.XXX.148 25
Trying 70.XXX.XXX.148...
Connected to 70.XXX.XXX.148.
Escape character is '^]'.
220 server1.example.com ESMTP Postfix
421 4.4.2 server1.example.com Error: timeout exceeded
Connection closed by foreign host.

Here is the output of nmap localhost:

[root@server1 ~]# nmap localhost

I have also downloaded the vmware image here: http://www.howtoforge.com/download.php?id=5374_0 and had the same results.

Any suggestions?

Thats the correct and expected output. The telnet prompt waits for input and as you did not enter something, it quits after 5 minutes automatically.

If you like to get the status codes from the smtp server, you have to type:

ehlo localhost

and then hit return after you opened the telnet connection.

Hi till,

This is what I got:

[root@server1 ~]# ehlo localhost
-bash: ehlo: command not found

You have to type this after you opened the telnet session to the mailserver.

Hi till,

That`s my problem, I can`t telnet into the localhost

[root@server1 ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 server1.example.com ESMTP Postfix

Hi till,

I reread what you posted and got this:

[root@server1 ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 server1.example.com ESMTP Postfix

250-STARTTLS
250-AUTH PLAIN LOGIN

250-ENHANCEDSTATUSCODES

The reason why I needed to know about telnet is that I needed to verify that STARTTLS was working.

I am trying to send a test message to gmail and I am getting this in my error log:

I am googling right now, however, if you have any suggestions, please let me know.

The reason why I needed to know about telnet is that I needed to verify that STARTTLS was working.

Then you should have asked this as question

Yes, starttls is working fine on your system but the ssl certificate from postfix seems to be corrupted. you might want to create a new ssl cert for postfix.

hi till,

Thanks for your patience, sorry about the lack of clarity, doing to many things at once again.

I created to SSL certificate. However, there is still this error:

May 31 10:10:11 server1 postfix/smtp[8042]: 322CAF05B6: to=<william.YYY@gmail.com>, relay=smtphm.sympatico.ca[65.55.172.251]:25, delay=0.7, delays=0.02/0.03/0.47/0.19, dsn=5.7.0, status=bounced (host smtphm.sympatico.ca[65.55.172.251] said: 530 5.7.0 Must issue a STARTTLS command first (in reply to MAIL FROM command))

I have been googling and digging around in the control panel, but have found nothing on STARTTLS. Do you know how I get the server to issue the "STARTTLS command first"?

Thanks
