I am having some problems with e-mail and I hope somebody could explain me on which side is the problem. Last 14 days I received 2 rejected messages. I am not sure if the problem is on my hosting side or recipient.

First message:

Hi. This is the qmail-send program at sipuk.myhosting.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

Remote host said: 554 5.7.1 <lizg@domainname.com>: Recipient address rejected: 421 MY_WEBSITE_IP greylisted by CYREN GlobalView IP reputation
Giving up on RECIPIENT_IP.


Which IP is greylisted, sender or recipient?

Second e-mail:

I am also not sure here, is the problem on my hosting or recipient?

Tnx!
