Ubuntu Networking :: Cannot POST Http - Unable To Send Mail Via Squirrelmail

Nov 23, 2010

I have a really weird (but consistent) problem with my Kubuntu 10.10 install: I cannot post some HTTP forms.

First off, this is a client PC problem. My squirrelmail on the server works fine. I just use squirrelmail 1.4.17 to troubleshoot the ubuntu desktop problem

I used an old (07.04) Ubuntu install which worked fine. Then I wiped the disk and installed Kubuntu 10.10 on the same hardware. Everything works but **some** HTTP post does not work (I can log in but not send mail or save draft). I noticed I cannot log in to Yahoo, for example.

My webhosting account can display the apache access_log. When I hit the <Send> button the POST request never arrives to the web server.

I use a router (Dlink DL-604) behind a DSL modem and ooma box. There is a Windows 7 PC and a Kubuntu PC connected to the router. I can use squirrelmail just fine from the Windows PC.

I tried several steps:
- reinstalled Kubuntu
- installed Firefox and Chromium (on top of reconq)
- ran from a CD on my other (Windows 7) PC
- installed Wireshark and compared the traffic (but was unable to pinpoint a problem)

The result was the same: the <Send> button just keeps waiting; the POST request never makes it to the web server.

This sounds (and is) scary and suspect. The fact that the "demo" Kubuntu install (from the CD on my other Windows PC) using the reconq exhibits the same problem on a totally different hardware leads me to believe this may be related to Kubuntu. For example, I had to type this very message on the Windows PC as I could not post it on the forum from my Kubuntu box.

Ubuntu Servers :: Client Can't Connect To Mail Server / Get It To Work?

Nov 19, 2010

I followed this tutorial:
Minus the Quota for the mailboxes, since I don't really care about that. But I don't think that should cause any problems in the configuration.
The server is in my local network.

I tried to connect with Thunderbird and Kmail. Kmal brings up an error message eventually, saying something about a time-out.
Squirrelmail says code...

I searched everything & everywhere only to see that more people have that same error message come up with Squirrelmail. From my understanding some have fixed the issue but I couldn't actually find a solution to this.

Does anyone know how to fix this?

Fedora Servers :: Unable To Connect Apache / Postfix And Php Mail Script

Aug 12, 2009

I installed FC10, and configured everything to work with my static IP address [URL]. As far as email goes everything works except for the php script on my website. This script worked fine on my previous install, and it appears to actually submit the email as shown in the maillog:

Aug 12 14:21:02 myhome postfix/pickup[27581]: 37406BFDD9: uid=48 from=<apache>
Aug 12 14:21:02 myhome postfix/cleanup[27783]: 37406BFDD9: message-id=<20090812192102.37406BFDD9@www.myhome.com>


I also created the following php script to test

(mail ("test@myhome","Test message","this is a test"))

And I was able to send successfully with this script with the only difference being it was sent by root rather than apache. This leads me to believe it's some sort of rights issue with the apache user. I wouldn't be surprised is SELinux was behind it all. I spent days and days after installing wordpress trying to get it to connect to mysql, and that turned out to be a SELinux issue.

Ubuntu Servers :: Apache -> Squirrelmail Not Accessible From Internet

May 4, 2010

I set up a mail server today. Everything works except I can't access the damn squirrelmail web interface from the internet.

I followed this guide here: [URL]

I can access just fine from a computer on my local network.


When I access http://mywanip/squirrelmail, i get a connection timeout.

When I access http://mywanip, I get the standard Apache "IT WORKS!" Page. (Rules out port forwarding)

According to the guide, that should allow me to access squirrelmail from the internet on my server. Its as if Squirrelmail is only available on my local interface and not on my wan interface? How do I check?

Fedora Servers :: Squirrelmail: Can't Access Localhost

Jun 1, 2010

I'm running Fedora 12 on x86_64. I've installed squirrelmail, along with dovecot on my office server, and cannot access it through http://localhost/webmail. I have followed all the configuration steps I could find (including http://www.server-world.info/en/note...12&p=httpd&f=7).

I know that everything else is working (I can send and receive mail, access IMAP mailboxes, webserver is working), browsing to


just gives me

"Problem loading page"

in Firefox. Sometimes, however the message is "Unable to connect."

I will add that I already tried installing Squirrelmail on another (i686) machine and had exactly the same problem.

/var/log/httpd/error_log says:

File does not exist: /var/www/html/squirrelmail

This makes it seem like aliasing is not working somehow.

Ubuntu Servers :: Internal Only Webmail / Can't Get Authentication Setup With Squirrelmail?

Nov 7, 2010

What is the fastest setup to do this? All I want is an internally authenticated webmail server that other servers can send mail to for collection of test emails. Don't need LDAP or anything fancy, just a internal LAN only webmail server. I've got Squirrelmail setup on Ubuntu Server and can't get authentication setup with Squirrelmail and every tutorial I read is way over complicated or has nothing on how to authenticate Squirrelmail with internal, system users.

Ubuntu Servers :: HTML PHP Email Configuration / Squirrelmail Setup

Sep 1, 2011

I'm having problems with emails containing HTML content. When Google downloads the email messages via POP3 from my squirrelmail server, the message does not display using HTML. I'm not sure if this is Google's fault or Squirrelmail's fault, but I've never had problems before on other servers running the same script and using squirrelmail. If I login to squirrelmail, I have the option to download the email message as an attachment. The attachment, if opened by my local browser, shows up as HTML content, and it is properly formatted. However, I'm using Google to download my emails and file them under my Gmail account. After Gmail downloads the messages, it shows up like this:

To admin@domainRemoved.com
Date Sat, Jul 30, 2011 at 6:07 PM
Subject Pending Registration

Content-type: text/html; charset=iso-8859-1
From: Name Removed <admin@domainRemoved.com>
Message-Id: <20110730234302.6B6FEDC08BA@eric-desktop>
Date: Sat, 30 Jul 2011 17:43:02 -0600 (MDT)

<p><b> After registering your client via your server, please visit the following URL to send them confirmation: </b></p>

I really need it to show up properly once Gmail downloads the messages, as it takes a long time to login to Squirrel mail and download each message as an attachment. My PHP Code Headers Look like this:
$headers = 'MIME-Version: 1.0' . " ";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . " ";
$headers .= "From: $uname <$email>";

Someone suggested that I remove the from my script. I did, and now the email shows a from sender as www-data www-data@domain.com. Before, the from field showed up as empty. However, my PHP script is designed to change the sender's information to the clients that contact me. Thus, if customer A contacts me, the email should be from customer A <custa@whatever.com>. However, it's not being changed by the PHP script. It works on every other server but mine. I think my postfix configuration isn't setup properly? What needs to be configured on it?

Ubuntu Servers :: Install Postfix In Order To User Squirrelmail Or Roundcube?

Nov 20, 2010

I'm configuring a server but at this time I can't send mail. I tried using the PHP mail() function and it didn't work. Webmin says I have no mail configured. I'll be the only user and mail recipient. I've used Squirrelmail and Roundcube before and liked them.

Do I need to install Postfix in order to user Squirrelmail or Roundcube? How should I set up mail?

Here's my setup:

10.04 LTS Server edition
Webmin 1.520
Apache 2.x
MySQL 5.x

Ubuntu Servers :: Secondary Mail Server And A Mail Gateway/relay?

Aug 3, 2011

Our primary mail server is Exchange 2003 Standard on Windows Server 2003 Standard - don't shout at me; I inherited it already set up this way.I have a couple of hardware identical redundant servers (HP ML350 boxes), all with very fast 2 or 4 disk arrays, multiple core CPUs and plenty of memory, and I am looking at two potential new additions to the infrastructure.

A secondary mail server is high on my list of priories. I've been well and truly bitten by Exchange in the past and given that this particular box has been running four years straight and that it's mail store is dangerously large, having a secondary mail server in place suddenly makes a lot of sense.

A new Exchange 2010 box is currently being set up, but the secondary mail server will remain in place even when the new Exchange server is brought online, so this won't be a wasted exercise.... I also want a gateway box in place to filter and relay mail to the primary server, or to the secondary server if the primary is unavailable. Currently our outer perimeter is:

ISP supplied CISCO router
Draytek VigorPro 5510 UTM

Untangle running in bridged mode (primarily used for SPAM filtering, URL blacklisting, and very little else) Exchange 2003 sits behind the Untangle box. This is how I want to end up:

CISCO >> Draytek >> Ubuntu gateway >> Exchange/secondary mail server

I know I could replace/remove the Draytek but I want it to remain for several reasons, including lots of VPN dial-in users already configured and that it offers us an additional layer of email antivirus scanning before things hit the Exchange box. No point switching all of our remote workers over to new tunnels unnecessarily...

I have done some research and have started testing a pilot secondary mail server using Ubuntu/postfix DNS is properly set up and MX records and reverse PTR records are all present and correct, and things are looking encouraging so far. Before I go out over deep waters and start to flounder, has anyone who has done something like this got any obvious howlers I should be looking to avoid ?

Ubuntu :: Telnet: Unable To Connect To Remote Host: Connection Refused

Jul 16, 2010

when i try a telnet to a host like that: telnet 1234 i got this: telnet: Unable to connect to remote host: Connection refused.

1/ does this mean that the problem is not due to a firewall, but that the host doesn't listen on the port 1234? other way does this mean that my firewall is authorizing traffic on the port 1234?

and when i try a telnet on another port like that: telnet 1235 i get: Trying ...

in this case this

2/ does this mean that the firewall is blocking the traffic between my host and the on the port 1235?

Networking :: Socket Programming - Connect To Port Y On IP X With Telnet

Sep 16, 2010

I have a customer who is complaining that they can connect to prt y on IP x with telnet. They are seeing the following:

telnet x.x.x.x y
Trying x.x.x.x...
Connected to x.x.x.x.
Escape character is '^]'.

after some time the connection of course times out. Connection closed by foreign host. There is no telnet service running on this port so they cannot do anything, but they are complaining tht the fact that telnet "connects" is a security risk. I am having difficulty explaining why they are able to connect with telnet. I know it has to do with the socket layer API in Linux but I am having difficulty explaining this sufficiently. I also can't just say "this is the way linux works" to them. I am looking through "UNIX Network Programming" by W.
