Email sending error because of too many connections

There were many reason of email sending error. One of them is because of too many connections to the server. This is the sample MDaemon email server logs of sending mail failure because of too many connections to the mail server.

Sender user is: user@mycompany.com
Recipient user is: theuser@telkom.net

In this log there is line:

Fri 2010-03-12 07:41:33: <-- 421 #4.4.5 Too many connections to this host Fri 2010-03-12 07:41:33: --> QUIT
Fri 2010-03-12 07:41:33: Socket connection closed by the other side (how rude!)

This mean the recipient mail server could not receive email from user@mycompany.com because in the same time the server receipt too many connection (may be from other email server) that could not be handled.

MDaemon server (Sender user mail server) will automatically resend the mail from user@mycompany.com to theuser@telkom.net next time depend on the setting of MDaemon mail server.

MDaemon Spam Filter system.

How spam filter works in MDaemon mail server system

1. MDaemon receipt mail from internet and then creates its files as tmp files
2. Massage was passed through Spam Filter and examine the content of email
3. Spam system will give score of content that suspected as spam content
4. If the score is more than setup score in MDaemon then the email will be refused

Here is the example of log SMTP process file generated by MDaemon Server.

MDaemon Mail Server

On this occasion I will discuss about MDaemon Email Server software.

MDaemon email server is software made by Alt-N technology. At this time (when I write this posting) the latest version is MDaemon version 10. MDaemon provides much convenience to the administrator of the mail server because the user interface using a graphical user interface is simple and easy to understand.

If you have trouble sending or receiving e-mail, you can see the status of an existing log file on the MDaemon. All events associated with the process of sending and receiving is fully recorded in the log files that can be arranged by us. Recording of the MDaemon log files can be set whether the log files recorded by day or by week. MDaemon can also separate the log data of the SMTP IN (receiving emails from users into MDaemon), SMTP OUT (sending email from MDaemon mail server to another), POP (taking email from MDaemon server by the user), Domain-POP (email retrieval POP by MDaemon from the POP server) and others.

Content Filter
Another important feature of MDaemon is the ability to perform filtering on incoming email. We can do it manually setting the filter on incoming email, for example, we do not want the incoming mail containing certain words in the message-body or in the email subject. To filter out emails containing the word 'buy' it we can set on content-filtering features of this.
In addition to filtering on the words, the process of filtering can also be done on an existing file attachment in an email received by MDaemon. We can filter out email based on the type of files on attachment file, for example to avoid the risk of virus from the executable file or script file; we can filter out emails with file attachments type .EXE or. VBS.

Spam Filter
Spam filter is a process that filters out email spam category. The process requires a spam filter that keeps the third-party spam databases. The process carried out by MDaemon spam filters by examining the contents of incoming email and then MDaemon will perform a check to a certain web site that keeps a database of spam, if the email contains the content sections listed in the database of email spam or not. Each component contains no spam then MDaemon will give a value or score that called SPAM SCORE. If the accumulated value of spam scores more than the allowed limitation then this email will be rejected or quarantined in accordance with the score obtained.

Antivirus
MDaemon provides the facility to scan incoming email whether or not containing the virus, but this feature is an add-on that must be installed into the MDaemon, so it is not directly active when we install MDaemon.
