There is a network claiming to be a security company, however the
activity appears to be a little more malicious, and appears to be
attempting buffer overflows against POP-SSL services.. (and other attacks).

Just thought it would be worth mentioning, you might want to keep an eye
out for traffic from this company...
Might want to make up your own mind, or maybe someone has more
information, but enough of a red flag, that thought it warranted posting
on the list.
Not sure yet if it is Dovecot, or the SSL libraries they are attempting
to break, but using a variety of SSL/TLS methods and connections...
Anyone with more information?
