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)?
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 ?
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 ?
Ok, this morning the message which server is responding to telnet is gone 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 ???
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?
My 3 ispconfig servers are on the same LAN. And when i do a telnet connection on the remote server (on which i can't send a mail) i have two differents results : The ispconfig where the mail is deferred can't connect with telnet My 2 others servers can do it ! My router is a Cisco and each one of my 3 servers have a static ip 195.101... ... On my 3 servers i have the same config : Debian Sarge perfect setup install + ISPConfig
Well, i tested telnet connection on all my others servers in my lan and this is ok except on one (the server on which mails are deferred) ! i don't understand... My firewall have the sames rules .... And i tested with firewall stoped and it is the same result In fact i have an answer of the remote server but it takes 10 or 15 minutes !!! telnet ***.***.***.***.fr 25 Trying ***.***.***.***... Connected to ***.***.***.***.***. Escape character is '^]'. 220 ***.***.***.***.fr ESMTP Service Ready 421 ***.***.***.***.fr Error: timeout exceeded What can i do ?
No, but today, it is ok e-mails were sent ! I made no change on my server but all is ok now... Telnet connection on the remote server on which i had a problem is faster ! ... I have no explanation except a problem on the remote server or on the router... Thanks a lot for your help !
