Thanks Rick,

I did check and my IP is not listed. Actually I can send to some domains like the shupp.org. I think some other domains may have implemented policy to block my domain automatically.
Do I need to check my server? or others?

Regards,

Kenneth

Hi all,

My email server has been working very well for a while.

However, it started to have problem in sending email yesterday. I test it with my hotmail account and found that: 1. I cannot send new email to hotmail account but I can reply the email sent by hotmail account. 2. Not just to hotmail, this problem also applies to other domains in different places.
3. I can receive email from anyone without any problem
4. Within the LAN, it still works very well.
5. I can send email to the toaster@shupp.org

Could anyone give me a hand?


Hi,

Have you checked to see if your IP is listed in some RBL ?
