It didn't work, Robert, because you didn't have the "$" modifier on the
condition line to make procmail substitute variables in the first place.
Without it, an unescaped dollar sign later in the line represents a newline,
so what you have there is searching for the following:
1. An expression that matches the expansion of the ^TO token (which is
anchored to the start of a line by its definition), followed by
2. A newline, followed at the start of the next line by
3. "foo(_at_)bar" [the backslash escapes the f, which didn't need escaping],
followed by
4. any character that is not a newline (the period is unescaped), and finally
5. "com".
Try this instead:
:0:
* $ ^TO$\foo(_at_)bar\(_dot_)com
foo
In fact, to avoid matches to things like
$foo(_at_)bar(_dot_)community(_dot_)edu, you might
want to do it this way:
:0:
* $ ^TO$\foo(_at_)bar\(_dot_)com\>
foo
