Hi

I m stuck with RH 3.0 ENTERPRISE + postfix 2.0.16 + isvw 5.0

Here is the how postfix + issm + mail server is setup

internet > | postfix 25 > ISVW 10025 > ISVW 10024 > postfix 25 (via
Transport Mapping smtp:[127.0.0.1]:20025 ) > MAIL SERVER LISTENING ON
20025 |

Everything functions well till I change the postfix config with webmin.
I m getting this error ;

connect to 127.0.0.1[127.0.0.1]: server dropped connection without
sending the initial greeting

If I disable imss content filter by removing the line
imss:[127.0.0.1]:10025
in the file etc/postix/main.cf

Things function normally except that mails are not scanned since > ISVW
10025 > ISVW 10024 > is by passed

The only way to get around this was to reinstall all from crash.

Now that the server is in production I can not reinstall anymore.

Any will be "vitally" appreciated.

Thank you

tg

The message "server dropped connection without sending the initial greeting" is
indicating a Postfix error message in it's LMTP transport when Postfix tries to
connect to the ISVW service, and gets no response at all.


In your IMSS config file, for "smtp_allow_client_ip", did you include the address 127.0.0.1 ?

I'd try telneting from the same machine to your various service ports on 127.0.0.1 to make sure
they are responding. For example: telnet 127.0.0.1 10025

Hi Greg

imss is installed in /opt/trend/isvw/
but the file imss.ini is not there

it is located in /opt/trend/isvw/mail/

I checked the imss.ini file
"smtp_allow_client_ip" is commented as
# smtp_allow_client_ip=127.0.0.1

I guess when it is commented any host can connect.

I uncommented and rebooted.

I still have the same error. connect to 127.0.0.1[127.0.0.1]: server
dropped connection without sending the initial greeting

Any idea ?

Thank you

Did you try the "telnet" connectivity tests I suggested?

yes I did

[root@tigrou mail]# telnet 127.0.0.1 10025
Trying 127.0.0.1...
Connected to tigrou.mydomain.com (127.0.0.1).
Escape character is '^]'.

after this it is imposible to send any message withj SMPTP commands. ie
helo mail from etc...

same situation if I telnet on port 10026

[root@tigrou mail]# telnet 127.0.0.1 10026
Trying 127.0.0.1...
Connected to tigrou.mydomain.com (127.0.0.1).
Escape character is '^]'.

aimposible to send any message withj SMTP commands. ie
helo mail from etc...

It appears that you're connecting up to port 10025, but the trend daemon is not
putting out a welcome banner. I believe it should look similar to this:

% telnet localhost 10025
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220-InterScan Version 3.6-Build_1166 $Date: 04/24/2001 22:13:0052$: Ready
220 interscan.nid.co.jp ESMTP Postfix

What about telnet to Postfix port 20025; does that work ? Any clues in any log files ?

no such banner on telnet 10025

non postfix mail sever listens and responds perfectly on this port

logs are full of

connect to 127.0.0.1[127.0.0.1]: server dropped connection without
sending the initial greeting

messages

any idea ?

hello

I finally discoverd the error.

Basically there seems to be a bug in webmin Version 1.200

If I change postfix settings with webmin

in /etc/postfix/main.cf values

myhostname

and

mydomain

are commented like

# myhostname =
# mydomain =

Thats the reason why issm sevices refuses connections from localhost
since the hostname has changed

Thank you for all
