For a few months now, starting in March / April and happening every day, someone has been sending 16 emails
from webtestx.com & the same from techn-site.net. They always originate in these subnets:
220.127.116.11/29 & 18.104.22.168/29 (which I have blocked). The peculiar thing is that each email has one
of the 2 domains but a different sender username and they are always sent to a different (invalid)
email@example.com. They appear to be just making up the names on both ends & trying
to send the email - which of course always fails.
Why do you think they are probing like this? The success rate is 0% yet they persist in sending to 32 unique
usernames from 32 unique usernames every night. Seems somewhat bizarre to me. Any thoughts or opinions
Here are some real examples:
