There are a couple of ways to do it. If you know that the numbers are 1-9, you could do this: header __LOCAL_MAILENGINE ALL =~ /mailengine[1-9]\.com/i (this is matching a single character. You could NOT do [1-12]) If you just want to allow for a number, you could do this: header __LOCAL_MAILENGINE ALL =~ /mailengine\d+\.com/i This one matches a number of any length. For more information, do a search for Perl regular expressions. -- Bowie
