How do write a script
which will send to /dev/null all e-mail
which have an empty 'To:' field ?
Let's rephrase that: Send to Dave Null all email which doesn't have a
To: field with something alphanumeric in it:
:0
* ! ^To: .*[a-z]
/dev/null
Do note that mail can validly have a more or less empty To: field and
instead specify the recipients in Cc:, and that you can easily
masquerade an empty To: field by putting some unimportant comment
there, like
To: recipient list not shown:;
or
To: Recipients of the Procmail mailing list <nobody(_at_)example(_dot_)com>
In fact, I don't think I have ever seen a message with a To: field
which was there but which was empty. Perhaps you are actually looking
for something else? Could you tell us what you are trying to
accomplish?
