It is my experience that it is both easier to read one expression, up to a point, and more efficient for procmail because it is running fewer instances of tests. The only time these are not true is when the long expression is REALLY long. I would say that the moment the line becomes difficult to read through on one screen, without scrolling back and forth, then split it into more than one.

Thanks,

When i want to match on multiple addresses with the TO_ macro, is it more efficient to match on One Big Regex:

:0:
* ^TO_([EMAIL PROTECTED]|[EMAIL PROTECTED]|[EMAIL PROTECTED])
destination-folder

or to match on Several Smaller Regexes:

:0:
* [EMAIL PROTECTED]
destination-folder

:0:
* [EMAIL PROTECTED]
destination-folder

:0:
* [EMAIL PROTECTED]
destination-folder

Is one method better than the other?
