Mail application timing out

Ok, I thought I could handle my way around a Linux system somewhat well enough, but I am beginning to think otherwise at the moment.

I have a client on a dedicated server (yes, my infamous Fedora Core 2 dedicated server) and recently he told me that he is not getting any web mails in his mailbox. I did some testing, and sure enough, mail is not sending from the server. So I did a little searching around and found my mail log and reviewed them. Apparently on every attempt to send, the connection to the SMTP server is timing out. What does that mean and how do I begin to look for fixes? I am not mail wizard whatsoever so this is all new to me. All help as always is much appreciated.

Here is the last few lines of my mail log:

Can you SSH to your server and try:

telnet 64.202.166.12 25

Does it connect (if it does, type "quit") and say?

Code: Select all

d11wtq@w3style:~$ telnet 64.202.166.12 25
Trying 64.202.166.12...
Connected to 64.202.166.12.

Connection closed by foreign host.

EDIT | That's where it's timing out and I'm just wondering if you have a routing issue (locally). Do "ifconfig" and "route -n"

Can you ping 68.178.207.254 ?

Now I'm no expert but I would have thought your routing table should look like:

Code: Select all

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
68.178.207.0     0.0.0.0         255.255.255.0     U     0      0        0 eth0
0.0.0.0         68.178.207.254  0.0.0.0         UG    0      0        0 eth0 
0.0.0.0         68.178.207.254  0.0.0.0         UG    0      0        0 eth0 
0.0.0.0         68.178.207.254  0.0.0.0         UG    0      0        0 eth0

Yes, I can ping that IP.

Posted: Mon Dec 18, 2006 12:21 pm

That IP is supposed to be routing outgoing traffic for you since it's your default gateway address (apart from on 68.x.x.x addresses). Something's wrong there.

Has anybody tweaked any network settings lately?

Not that I am aware of. Hell, I don't even know how to change network settings yet.

Any luck?

I realized that a lot of my clients business operates during the daytime. I figured that if something went haywire on reboot, it would be best to happen at a time when it wouldn't impact their businesses too much, so I am going to wait until later tonight, my time.

By the time I get around to screwing with this it will be 7 to 8 AM over there. So it's all good.
