This is an updated F-10 desktop computer, my ISP is a satellite service,
wildblue.net who quit providing mail servers and switched to gmail about
a year ago.
Recently I have been observing a continuous stream of blocked port 25
connections from this box 192.168.1.9 in the Firestarter log. The normal
SMTP port is 465. They appear to be directed at a google name server
although /etc/resolv.conf shows
[bobg@box9 ~]$ cat /etc/resolv.conf
nameserver 208.67.220.220
nameserver 208.67.222.222
# nameserver 12/189.32.61
And I see the following logged:
/var/log/messages

I guess it's not hurting anything but I would feel better if I didn't
see all this activity apparently going nowhere. I don't know how to find
what's causing it, at least I haven't found it yet.
Any suggestions?
