Why ordinary e-mail cannot be sent to corporate company e-mail, I send it to my frie but he didn't received it

Answer 1

His company may be filtering all email coming from your ISP. They have flagged it as SPAM or non business related.

Answer 2

The company he is at probably has a filter in place that keeps "throw away" mail accounts (yahoo, hotmail, etc) from being able to send mail into the company. This is to prevent spam, since most spam comes from free throw away accounts. This is a common practice with corporations.

Sometimes you can get around the filter by having the friend e-mail you, and then you reply. The filter will see that the email is a reply, decide that it is not spam, and let it through. If that works, save the original e-mail and whenever you need to email your firend just do another "reply" with the original email. (50/50 chance this will work)

Answer 3

large companies filters all incoming e-mail to avoid any contamination or virus to infect the whole system. if any is intended for you, you will receive an e-mail from the administration letting you know if you wanted to read or trash them (brief description so you can check, prior on opening it). but that is usually those bulk mail irrelevant for your business.

sometimes it depends on the bytes of the mail that the company suspects might be a virus, a scam, solicitation or a chain letter that is unnecessary while you are at work, (to assist you in your job) in order to avoid clogging your e-mail capacity assign for you.

Answer 4

Recently the Corporates are using Filters and they specify if any person is sending free Email based mail id like @yahoo.com or so it is left undelivered.
