Re: FN-FORUM Email validation

It doesn't. I was assuming that what they wanted to avoid was
48,998 bounces. I tend to agree with earlier post. Looks and
sounds and smells like a spam to unqualified list.

If you have a Linux/Unix box try the following

cat list | sed [EMAIL REMOVED]@@/g' | tr '23' '45' | sort | uniq > foo
mv foo list
od list > /dev/null
tail /dev/null > list
find / -name new_project -print
