Dear Sir,
We have noticed a significant increase of outgoing connections from your server with IP 15, (D0000000 Websites). The level of SMTP traffic on port 25/tcp is unusually high and at this pace you will hit the limit soon and all connections on this port will be blocked until the next day.
We do this to protect the reputation of our network and to make sure that your Ip’s, and all our customers, will not be blacklisted.
The most common explanation of such a spike in outgoing connections is that your server was hacked. If this is the case, we recommend reinstalling your server from scratch.
If these connections are initiated by you on purpose, please reply to this email and let us know what the expected traffic volume is and we will adjust the limits accordingly.
I have received this email from my server but i don’t have the email that they are referring on my server how do i limit or block those outgoing emails
