SMTP Not Working Properly On IIS
Jan 15, 2008
I set up my own SMTP server on IIS.
Most of the time it sends and recieves the email OK.
From time to time, the mails bounce. For example if I send to someone at Hanmail (major korean provider) then it always bounces. Similarly, sometimes people say they sent an email to the server and it bounced back to them.
I guess something is not set up right, maybe MX record or some other mysterious thing. How can I troubleshoot/solve this?
I MUST fix this so I will be back to check on this thread often,

I am using SSL on my site but am having trouble in getting it to work correctly. I want to make it mandatory that the sections in <webaddress>/members and <webaddress>/admin are protected by SSL. I currently have the following in the httpd.conf file:
SSLEngine on
SSLCertificateFile /usr/local/home/pm42/finalcert.pem
SSLCertificateKeyFile /usr/local/home/pm42/privkey.pem
SSLCertificateChainFile /usr/local/home/pm42/finalcert.pem
but I dont know what to do next.

I have a slight problem with a cron job I have setup.
I wanted to save a copy of iptables every hour to a folder, so I created a script... here it is:
Code:
varDate=`date +%y%m%d`
varTime=`date +%H%M`
filename="IPtablesBackup-$varDate-$varTime"
iptables-save -c > /etc/IPtablesBackup/$filename
and called is Backup-Script.sh
Now if I just execute the script will in root ./Backup-Script.sh I get a new file with the correct filename and iptables info is saved ! Great ! So then I thought, how can I setup this automatically every hour.
Which leads me on to my problem. I inputted "crontab -e" added this line
Code:
59 * * * * /etc/IPtablesBackup/Backup-Script.sh
The problem is the script is run, I know because it creates a new file with the correct time and date, however the file is empty?
I have set Backup-Script.sh to 777 and owner and group are both root?

Added this in the httpd.conf but it is still pointing to the main domain xxxx.com
--------------
<VirtualHost *:80>
DocumentRoot /xxx/xxx/webmail
ServerName webmail.xxxxx.com
</VirtualHost>
-----------------
whenever i type webmail.xxxxx.com, it will see the content of xxxxx.com.

I am looking for a replacement to my existing ISPConfig 3.x installation and have heard a lot of good things about Plesk, so I decided to put up a test server with a trial version of Plesk 12.The server is running Centos 6.5 64-bit minimal install with all system updates applied before installing Plesk. After installing Plesk I used the commands from the attached text-file.After compiling PHP 5.5.20 with no errors displayed on screen I created a new subscription plan as a copy of the #default domain" plan and changed the name to "PHP 5.5 website" and in the Hosting Parameters I changed PHP to run still run as a FastCGI application but use my compiled PHP 5.5.20 instead of the OS vendors PHP 5.3.3.The configure options used are the same as I did use for my ISPConfig 3.x servers.I also tried the configure options shown here: [URL]... But the command ends with a "configure: WARNING: unrecopgnized options: --enable-fastcgi"
If I compile with the attached script I get a HTTP 500 error when visiting the selected website (which is a clean installation of Drupal 7.34) and in the error_log for my test site I get this:
"
[Sun Dec 28 18:51:48 2014] [warn] [client x.x.x.x] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[Sun Dec 28 18:51:48 2014] [error] [client x.x.x.x] Premature end of script headers: index.php
"
x.x.x.x is the internal IP of my router/firewall.I have also looked in the Plesk Administrator GuideIs there a known issue with Plesk 12 and CentOS 6.5 64-bit when wanting to use multiple versions of PHP, since both the version compiled using the KB article above and my own attached script worked fine on my ISPConfig 3.x servers.

We can no longer create a working subscription
Microsoft Windows Server 2012 R2
12.0.18 Update #26
After the creation of a subscription, DNS does not work properly.
The last successful subcription was created Sept 26, 2014.
I thought something ontoward had happened at first so attempted to delete the subscription and re-create.
On attempting to delete the subscription the following error is given
Error: Some of the selected subscriptions were not removed.
Unable to remove domain: Error during domain.com removeZone: dnsmng failed: Unknown error 0x80131509 (COM Interop Error 80131509, Description: System.InvalidOperationException: Operation is not valid due to the current state of the object. at System.Management.ManagementObject.Delete(DeleteOptions options) at System.Management.ManagementObject.Delete() at WMIMsDNS.Provider.DeleteRecordsByType(String zone, String type) at WMIMsDNS.Provider.DeleteZone(String zone, UInt32& serial)) at removeZone ZoneName = 'domain.com'Click to expand...

I'm not a pro when it comes to networking, so I was hoping someone could help me out here.
Sending email via CDONTS on my desktop machine used to work fine but has recently stopped. In my event log there is a warning from source SMTPSVC with the details.
Message delivery to the remote domain 'domain.co.uk' failed. The error message is 'An SMTP protocol error occurred.
'. The SMTP verb which caused the error is 'RCPT'. The response from the remote server is '504 <williams-pc>: Helo command rejected: need fully-qualified hostname
I've heard people mention DNS suffix and putting your domain in places. However, my computer is not on a complex network, it isn't part of a intranet or any other corporate IT setup, its just a single computer connecting to the internet on a modem.

I have been having great trouble sending mails from my local Thunderbird/Windows client to my Debian/Exim-server via TLS/SMTP.
I am no expert on TLS and SMTP, but I managed to create a server certificate and set up a secure (TLS) connection more than a year ago, and it has been working fine until it suddenly stopped working a couple of weeks ago.
Sending to external addresses from web pages still works fine, the problem seems to be in the SMTP connection. If I try to "telnet xxx.xxx.xxx.xxx 25" I get no reply whatsoever (it seems to connect but it just gives me a blank screen with a blinking cursor) and I am wondering if there is a firewall issue or if I am simply not running the right daemon to listening for incoming SMTP connections...
POP continues to work fine with teapop/stunnel enabled.
I am running Exim 4.63-17 on Debian Etch. I configured Exim to be of the type "internet site; mail is sent and received directly using SMTP"
==============================
Firewall shouldn't be a problem (?):
debian:~# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
==============================
I really don't know what to do. I have tried running:
tail -f /var/log/daemon.log
Which responds when I access my mail using POP but not when I try to send using SMTP.

I have just purchased a dedicated server running Windows Server 2003 (IIS).
I have a website with a contact form - which I know works because it was working when I had it hosted somewhere else.
My question is how do I set-up my server so that the contact form will work. I know it's something to do with SMTP -- But i honestly have not idea what i am meant to do.
I wish there was a SLOW step-by-step guide on how to setup the SMTP on the server to send emails.!

I'm using a 1blu.de vServer. On my VPS is Plesk 11.5 with centOS 6 installed. I created my Webspace [URL] .... and removed the Mail Services and activated the MSMTP plugin because I'm using the webserver from the hoster 1blu.de.
I activated the Firewall with the "allow any connection" rule.
In Plesk Tools & Settings > External SMTP Server I filled in the server informations smtp.1blu.de password & username. I checked all three boxes -> SMTP needs auth, allow user scripts ...
I installed Wordpress 3.9.2 with a Theme that uses PHP Mail function. The contact form is not sending any messages out. So I tried other php mail scripts but it doesn't work.
[URL] ....
Code:
<html>
<head><title>PHP Mail() test</title></head>
<body>
This form will attempt to send a test email. Please enter where this test should be sent to
<br><p>
<form action = "sendmail.php" method = "post" name="sendmail">
Enter an email address: <input type = "text" name = "to"><br>
<input type="submit" value="Send" name="submit"><input type="reset" value="Reset" name="reset"><br><p>
[URL] ....
Where can I find the log file that could give me information?
I just want to use php mail for my wordpress contact form and for a project application.

I need to block a specific IP:
93.6.224.242
It adds fine when I do:
iptables -A INPUT -s 93.6.224.242 -j DROP
However, the IP is still accessing files and pages on the site according to Apache:
When I ban other IP's they are blocked from accessing anything on the server (e.g. it wouldn't even reach Apache level because of firewall), but this IP just isn't banning properly.

I installed VNC on my VPS using a guide I found here. I installed KDE. It all works but when I view the VPS through VNC on my windows PC the text on the screen appears to be squares as if its a non supported language.

I've uploaded a screenshot to better help you understand what I mean.

As title suggests I'm looking to make sure my hosting is set up to respond with valid PTR information so my server generated emails aren't flagged as spam.
I have full SSH access to the machine at root level.
Running a CentOS machine but there are also other virtual hosts using a shared ip.

A client recently moved one of their domains to one&one (night mare I know) he then asked us to repoint the domain name to our servers using out name servers.
We have done this and it is not resolving to our server.
The problem is that the site is no longer showing and their emails are down.
I used a domain dossier and the DNS record looks like it should be changed but I'd like some confirmation on this.

how I can verify that my mail server is configured properly?
This is the problem:
I can send out mail without a problem, but I cannot receive mail from external domains (eg: google or hotmail).
Some of the message have weird bounce backs like:
PERM_FAILURE: SMTP Error (state 13): 550 No Such User Here
But the user does exist... I am logged into it right now.

There has been a recent rash of Windows 2003 customers being hacked and having "UTorrent" installed, as well as having their Administrator password changed, rendering the server inaccessible.
At the moment, we have yet to determine the vulnerability in Windows allowing the hackers to breach the systems however we believe it is related to RDP.
We highly suggest you are complying with the following, to lessen your risk of having your server compromised:
1) Run RDP on a non-standard port
[url]
2) Run a software firewall on your machine, blocking ALL unnecessary ports on your server. You should only have the bare minimum open.
3) Limit any non-public access to your IP and trusted IP's only. This will prevent any other outside networks or servers from reaching your machine through ports which are not meant to be public (http for example)
4) Ensure you have FULL updates for your Windows O/S, immediately.
5) Ensure any 3rd party software you are running, has also been fully updated to the latest version including any patches.
Please make sure these suggestions are implemented immediately to lessen you risk of being hacked by the current wave of exploits.

I am in the process of upgrading from apache 2.2.21 to apache 2.4.3. I'm using apache lounge's compiled 2.4.3 by the way. I'm working on a windows 7 SP1 64 bit workstation.
My old 2.2.21 was configured to use ssl with client pki authentication. When I configure 2.4.3 with the ssl options and move the CAs, private key and server certificate from my old 2.2.21 instance I get the following error.
