[Fedora-i18n-list] Solution for "Can't communicate with IIIM server" error

[Lawrence Lim]

To all members,
If you have encountered the "Can't communicate with IIIM Server" error, 
please give Descender's solution a try, and if the feedback is positive, 
I'll put it up as an FAQ's solution. Also note that after making changes 
in the hosts.allow, restore the htt.conf file back to the original form 
and see if the error persists. I look forward to your feedback.

Great work Descender!


Thanks,
Lawrence
