Postfix problem : read timeout
 
Hello,

i have a problem that i don't understand on my ispconfig server ISPConfig 2.1.1 released (Debian 3.1 perfect setup).

My server is ok and is in production since november 2005

I have mail in my postfix queue with "read timeout"

624D76043BB 91243 Wed Apr 19 11:23:25 simon@****.org
(connect to **.**.fr [192.**.**.**]: read timeout)
**.**@**.fr

When i test email address on E-Mail tester on http://www.dnsstuff.com/ the address seems to be ok !!!

I have this problem with several addresses.

Have you an idea ?

Thanks for your help and your great work ! :)

Seems the server isn't responding. What's the output of
Code:

telnet **.**.fr 25
(of course, you must replace **.**.fr appropriately)?

Code:

telnet **.**.fr 25
Trying **.**.****...
Connected to **.**.fr.
Escape character is '^]'.

Then the remote server isn't responding properly...

DarkBen 19th April 2006 15:11

Ok,

i tested another domain where i have a "read timeout"

Code:

telnet **.**.net 25
Trying ***.***.***.***...
Connected to **.net.
Escape character is '^]'.
ehlo localhost

It seems to be ok but i can't "Logout" and i have not answer from the server when i type ehlo command.

It seems that the remote server is not ok ?

DarkBen 19th April 2006 16:35

I test another domain on which I have this probleme :

Code:

telnet ***.***.fr 25
Trying 192.***.***.***...
Connected to ***.***.fr.
Escape character is '^]'.
ehlo localhost
220 ***.***.fr ESMTP Postfix
250-***.***.fr
250-PIPELINING
250-SIZE 12582912
250-VRFY
250-ETRN
250 8BITMIME
VRFY sebastien.***@***.fr
252 sebastien.***@***.fr
quit
221 Bye

I don't understand why the mail is "deferred" with "read timeout" ...

Can you help me ?

falko 19th April 2006 21:55

Maybe it's some kind of firewall problem...

DarkBen 20th April 2006 11:15

Ok,

this morning the message which server is responding to telnet is gone :D

But the others are again deferred but i can't connect to the remote servers with telnet (but ping, traceroute and DNS check are ok). The telnet connection on port 25 is it always possible when a remote server is ok ?

Thanks for your answers

I'm sure that i have a problem on my server now !

i tested telnet connection on 2 others servers running ISPConfig (on the same lan) and it is ok !

my server isn't connecting on remote server then on the others ISPConfig i can do it !

Server 1 :
Code:

telnet ***.***.***.***.fr 25
Trying ***.***.***.***...
Connected to ***.***.***.***.fr.
Escape character is '^]'.

Server 2 and 3 :

Code:

telnet ***.***.***.***.fr 25
Trying ***.***.***.***...
Connected to ***.***.***.***.fr.
Escape character is '^]'.
220 ***.***.***.***.fr ESMTP Service Ready
ehlo localhost
250-***.***.***.***.fr
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250 8BITMIME
quit
221 Bye
Connection closed by foreign host.


What can i doing ???

falko 20th April 2006 16:26

The servers that you can connect to (ISPConfig) are in your local network, and the others are outside your local network? Maybe it's a router problem. A customer of us once had the same problem until he found out it was caused by his router. What make is your router?
