I wrote a maildroprc:

\
( /^From:.*user2.*/ ) \
) \
)
{
to /mail/junk/Maildir
}
-----------------------------------------
Now the maildroprc regex above means:
If an email is being sent to "all" and is coming from either
"user1" or "user2", treat is as junk.
My question is, how do you negate the maildroprc regex? How do you
turn it around so that if the email is NOT from "user1" and NOT
from "user2", then treat it as junk.
I think it would be this (line-continuation characters and redundant
parens removed for readability):
if
(
/^To:.*all.*/
&&
! /^From:.*user1.*/
&&
! /^From:.*user2.*/
)
That's wrong. The negation of A && B && C is !A || !B || !C.
Easier changing can be achieved by negating the whole, i.e. !(A && B
&& C), or by using an else clause.
Yes, but that's not what was specified. The original regex (aside
from the apparent typo in the middle) was:
A && ( B || C)
And based on my reading of his question, he just wanted to negate the
second part. So that goes like this:
A && !( B || C)
or
A && !B && !C
Ooops, yes, you're right...
I beg your pardon for my outwitted post.
