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?
