I get a lot of spam where the "Sent" field in Mailwasher is blank.
The Sent field is normally right above the "From" line in the Header, and looks like this:
Date: Sat, 23 May 2009
I tried to create a filter where if there was no "Date:" found in the header, to set flag the email for deletion.
Unfortunately, the 3rd line of every email also has this line:
Delivery-date: Sat, 23 May 2009 17:08:07 -0600
...Which also has "date:" in the header. Any ideas on how to set a filter that successfully blocks an empty "Sent" field?
Thanks in advance.
