Your must have reliable Email to do business on the Internet To be successful in doing business on the Internet, you must be vigilant to ensure that your emails are getting delivered. When you send a message and hope for a reply, ensure that your message asks for a reply. If you do not get a reply, you need to investigate. The Bad News
Fortunately, it is possible to take positive action to discover, report and then get email problems fixed. Following is a description of some of the tools you can use to discover the reason for the problem. How can you have email problems when you didn't do anything wrong? Internet Service Providers provide email services that are shared by hundreds or thousands of users. If one of those users misbehaves or is a spammer, then the entire mail server is blacklisted because it is recognized as a source of spam. How do I determine my email server?
If you send email via a web mail service with your web browser then you probably did not configure your mail server. In this case, it is probably easiest to simply send an email message to yourself and then look at the email header where you will find the email server details. Most web mail systems provide some mechanism for you to view the header information that accompanies each mail message. You will need to study your web mail system to discover how you can display the email header information. At the top of the header you will find a message identifying your email server as in the following message examples: Received: from mail.yourhostingservice.com [19.24.24.88] by yourhostingservice.com Received: from web32906.mail.mud.yahoo.com [209.191.69.83] by yourserver.com Received: from bay0-omc2-s9.bay0.hotmail.com [65.54.246.145] by yourserver.com Received: from hs-out-2122.google.com [64.233.178.240] by yourserver.com How can I view the email header? Each email program has its own way of viewing
the email header information that is part of each email message. How do I determine the IP address of my mail server? If you have checked your email header you will find an address like 64.233.178.240 in the example above. Otherwise, go to http://www.mxtoolbox.com, enter the domain name of your mail server, e.g. rogers.com, and then press the MX LOOKUP button and the address will be displayed.

your mail server

The root cause for email unreliability is that unwanted spam email is so intrusive that many varied uncoordinated and imperfect solutions have been implemented to try to fix the spam problem. The consequence is that you may be unable to successfully send some messages. (1) You may find it difficult to determine that a failure has occurred. (2) If you do recognize that your messages are not being received, you may find it difficult to determine why your messages on not being received. The most common cause of this problem is that the mail server that you are sending to, is blocking your messages because your mail server is on a black list. Your mail server is a computer managed by your ISP Internet Service Provider who must be made aware of the problem so that they can fix it. In many cases, when your ISP investigates they will discover and report that they forwarded the message correctly and the problem must be at the other end. At the other end, the mail server of you client may be blocking your messages because your server is on a black list. You and your ISP have no control on your clients server and will find it difficult or impossible to determine which black list is the problem. Many ISPs are not very helpful in finding the reason for the problem and if that is the case then you should; (1) stop doing business with your ISP and get another more reliable and reasonable ISP or else (2) become knowledgeable and identify the problem yourself. Unfortunately in most cases, you will be unable to fix the problem, but if you can show your ISP that their server is on a black list, you should be able to get them to correct that situation by encouraging them to get themselves removed from the blacklist. Some of the providers of blacklists have websites that provide status information on the mail servers that are included on these black lists. If you find your mail server on one of these black lists, report it to your ISP and get them to take action to remove their server from the black list. Most black lists have a procedure where the ISP must prove that they have taken action to fix the problem. Example website to check follow: (1) Go to http://www.five-ten-sg.com and then go to the blackholes.five-ten-sg.com link where you can enter an IP address to determine if it has a problem. (2) Go to http://spamcannibal.org where you can check an IP address to see if has been a source of spam. (3) Go to http://www.uceprotect.net where you can check to see if an IP address is on the blacklist.
