Use Unix/Linux command diff … & grep for non-matching output & send that to a file & u will have all the unique email address .. excluding the ones u have in other file.

Assuming u have EMAIL1 file with all the bad email address, that also exist in the full email list known as EMAIL2 file. Than do the following

$ diff EMAILS1 EMAILS2 |grep @|sed ‘s/^< //’ > UNIQUE_EMAILS

UNIQUE_EMAILS will have only email addresses that will not be in EMAIL1 file (aka all good email addresses)

Excellent solution! :k: :k: - totally forgot about diff… arrggh! too much Windows for the last few years.
