We want to protect our users from emails containing spam, viruses, malicious coding, key-loggers and Trojans.
When your email server sends your email to our email servers, your server starts the delivery process by announcing its identity. Your server's identity could be something like:-
Our email server then, instantly, checks the identity given by your server is genuine. Our server also checks whether that identity is registered to the IP address used by your server.
If either of these security checks fail, our servers will normally refuse to accept your email. Its nothing personal, just good Internet security.
When our servers reject incoming emails, our servers always send a simple message in plain English describing the problem. If your email server is working correctly, your email server should always pass that message to you.
If the email servers you use are not 100% correctly set-up, there will be occasions when our servers, or another system's servers, will refuse to accept your emails. This is why it is so important that the mail servers you use always give you a copy of any rejection message.
Email servers using Microsoft Corporation of the USA software, regularly announce false or even non-existent identities. Microsoft itself is guilty, but because Microsoft is so big and rich, it arrogantly does not care how or what it does. However we do care about security and we will, and we certainly do, reject emails from any server, even those owned and operated by Microsoft. For example,
Host name : bay0-svm-s003.bay0.hotmail.com = 22.214.171.124
HELO / EHLO : BAY0-XMR-027.phx.gbl = No IP Address
These Microsoft email servers are known to issue false, and sometimes non-existent identities:-
In our professional experience, USA software corporation Microsoft makes bad software. It does not obey international Internet standards. Email servers using Microsoft
regularly have problems working with non-Microsoft email servers, because Microsoft does not use correct procedures.
The majority of professionally run email servers always use genuine identities. However some email servers ignore basic security issues, perhaps because their technical staff do not know very much about computer systems or because their technical staff do not care.
Our motto is:-
When in doubt, keep potential spam out !
Our security procedures, including other procedures not mentioned here, are good, fair and reasonable. We successfully protect our users from unwanted email junk and other email dangers. Consequently our users never normally receive spam, viruses or other nasty attachments.
Microsoft is often a nightmare. That is why we are never use Microsoft software. We use the superior and free Linux instead - why pay money for sub-standard software when you get get superior software and updates for free ? Do you really like wasting money ?
If you are using expensive Microsoft software which comes with free bugs, did you know clever and competent people use Unix-type software, for example BSD, Solaris, Linux etc., which are free. Yes, free including the virus checkers. As a bonus, Microsoft viruses do not work on BSD, Solaris or Linux.
Microsoft mail servers have basic technical defects including failing to recognise SMTP error code 550 (undeliverable email) and failing to alert the email's sender to the mail sending problem.
