Have you got access rules on your f/w to allow this (or port translations if applicable) for smtp (TCP/25)

I cannot connect to 84.24.38.145 on port 25 so I suspect the access is not setup into the smtp svc on KMS

you are correct in what SMTP does. However it is better to say that SMTP transfers mails between SMTP servers until it reaches its destination SMTP server. Therefore it is very relavant in this situation.

if I do a telnet 84.24.38.145 25 whichshould connect to the smtp server running at that address then it fails. Therefore your SMTP server seems to be misconfigured, not running, or firewalled.

Actually it stands for Simple Mail Transfer Protocol!!

It has everything to do with it, SMTP is the way emails are delivered across the internet. (Sent and Received)

If your firewall and KMS were configured correctly I could connect to your IP on TCP25, I can't and therefore they are not.

Check your firewall config and the access controls on your KMS SMTP service and next time be prepared to listen to advice when you ask for it.

The firewall config looks OK to me (Assuming the KMS server is 192.168.2.114)

Can you connect to the KMS SMTP service locally?

From a PC on the LAN try typing "telnet 192.168.2.114 25" in a comamnd prompt. If your SMTP service is running on port 25 you should get a response like:

"220 mail.aolex.net Kerio MailServer 5.7.10 ESMTP ready"

If this works OK then the problem must be with access controls on the service. Does the SMTP service startup OK (Have you got anything else that could be running on port 25 to block it's startup

I can connect to the other services (IMAP etc) through the firewall so there is no problem with routing/gateways etc.

Hope this helps

i made the telnet thing and here is the answer :

220 cp250875-b Kerio MailServer 5.7.10 ESMTP ready


cp250875-b is my computer name . the other computer
in the network si cp250875-a ...

Have you looked at the SMTP IP Access Settings?

Click Services-SMTP-Edit & then Access Tab.

Are there any IP address groups associated with it.

Also have you looked in the warning/error logs to see if the connection attempts are being rejected.

Also you could set the debug log to log SMTP daemon related events and see what messages are generated on connection attempts

Hmmm, I am running out of ideas here...

Did you check the logs to see if connections are being rejected?

Is this a new install that has never worked or has something changed?

Interesting problem.

I could telnet into your POP server, but not your SMTP server, so I would lean towards your ISP blocking port 25 access (not unheard of).

Try using another port for SMTP. If this works, then the problem is definately your ISP. There are plenty of articles about ISP's blocking port 25 on the web if you need further info.
