Esteemed Colleagues,
I recently set up a mailman mailing list to help facilitate communication about the Icarus project. <shameless plug>The Icarus project is a semi-official BYU high-altitude ballooning project. More information can be found at http://icarus.byu.edu. We are encouraging anybody who as an interest to get involved to help the project progress. </shameless plug>
In looking over the postfix logs, I've noticed several entries like this:
Aug 3 01:01:15 icarus postfix/smtpd[573]: connect from unknown[222.183.140.102]Aug 3 01:01:17 icarus postfix/smtpd[573]: lost connection after EHLO from unknown[222.183.140.102]
Aug 3 01:01:17 icarus postfix/smtpd[573]: disconnect from unknown[222.183.140.102]
Now, to my untrained eye, it looks as if someone is trying to reply mail^H^H^H^Hspam through the icarus mailserver. I think that I've gotten everything locked down to prevent that, but just in case, are there any other precautions I can/should take?
Thanks, -Hyrum
