SMTP error with mail client

[glinux]

hey all,

here's my situation. I'm using sympatico as my ISP/e-mail provider.
I have a linux box using Kontact via Rogers account.

I have configured Kontact to work properly while connected directly to the Symaptico DSL modem.
Now that I have this linux box working off a Rogers modem, I can no longer send any emails.

I get the following error:

Sending failed:
Could not connect to host smtp1.sympatico.ca.
The message will stay in the 'outbox' folder until you either fix the problem (e.g. a broken address) or remove the message from the 'outbox' folder.
The following transport protocol was used:
Proietto

Some quick facts:
No ports are blocked
No firewall being used -- other than router, but nothing restricted
No proxy server being used
Usernames and passwords are verified and working

Any suggestions ?

I never used Kontact and dont know what it is but all email systems are working in the same way so I give it a try. Your problem seems to be something to do with dns name resolution
------------
Are you using standard port 110 to d/l mail and port 25 to send mail?
firstly try >nslookup smtp1.sympatico.ca
does it resolve this name to IP?
you should get something like below...if not then something to do with your dns setting in the ip configuration section.
[root@frontend ~]# nslookup smtp1.sympatico.ca
Server: 61.9.133.193
Address: 61.9.133.193#53

Non-authoritative answer:
Name: smtp1.sympatico.ca
Address: 209.226.175.63


Secondly try to telnet to the mail server on port 25 to test communication, you should get something like below.
--[root@frontend ~]# telnet 209.226.175.63 25
Trying 209.226.175.63...
Connected to smtp1.sympatico.ca (209.226.175.63).

Let us know then we can go from there...

Something to do with the connection then, you need to be able to connect to your ISP mail server on port 25/TCP inorder to send mail


This is what I get from my end, it means connection has established.

It seems I not even able to ping the smtp server at sympatico.

Ping just times out.
Do you think sympatico is blocking this ?

Ping uses icmp-type 8 for ping reply, most of the time they are blocking this some where in the router firewall.

If sending mail, the port it need is 25 TCP, I could telnet to that port from my computer so your ISP is not blocking it...except they are blocking you only.

Do you have you TCP/IP settings right?..ie default gateway address
What IP do you have? On your machine?
If you are using private IP behind router, does your router support NAT?
Double check to see if your firewall/router is blocking outgoing traffic

[glinux]

I have already checked my router settings.
No ports have been blocked.

Keep in mind that i am on a different domain.

Whenever I connect my linux connect directly to my symatico connection.....everything works.

When I connect my linux box to the internet via an alternate provider (Rogers) .....I unable to connect to my smtp server, nor telnet into it.

I have been told that sympatico blocks port 25 ??????????

I'm trying to verify this, and awaiting there response, unless someone been there or has gone through this already.

It sounds more like "Rogers" is blocking port 25 rather than your mail server (or it could be your mail server is blocking incoming mail from Rogers IP range). To test it out do the following to get the whole list of yahoo smtp servers.
>nslookup <enter>
>set type=mx <enter>
>yahoo.com<enter>
that should give you the whole list of yahoo mail servers.

Then telnet to a few of them on to see if you can establish connection though port 25. You should get something like below if everything goes right

[root@frontend ~]# nslookup
> set type=mx
> yahoo.com
Server: 61.9.133.193
Address: 61.9.133.193#53
