I cannot send an email or respond to a hotmail account
I tried to respond to a friend's email from a week ago and I get a Mail Delivery Failure notice. It said that Hotmail is on a blocked list. How do I get it unblocked? Thank you.
Additional System Details
- Shockwave Flash 32.0 r0
- User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:64.0) Gecko/20100101 Firefox/64.0
can you post a screen shot?

Microsoft either has blocked your IP address, or a whole block of IP addresses representing your ISP, or they have blocked the mail service https://www.zimbra.com/
I can't tell exactly who is blocked. It has nothing to do with Mozilla. You could try to get around the problem by using a VPN, which will replace your personal IP address with that of the VPN server. If that fails, you will not be able to use the Zimbra mail servers.
Once a mail server is blocked, it is extremely difficult to get it unblocked because there are countless independent blacklists out there. Removing the block from every blacklist is hardly possible.
Can you please clarify if you are using Thunderbird or Firefox with a web-based email system?
