The expressions I create are used primarily with 'sieve' in conjunction with Dovecot. I am also thinking of possibly creating a few for use with Postfix. I believe dovecot simply uses the standard posix 'extended regular expression' syntax as seen in programs like grep(1). [See: http://ietfreport.isoc.org/idref/draft-ietf-sieve-regex ] In principle, this means you can write your test data into a file, and test it by running it through grep(1) using the -E flag: grep -E 'foo@(bar|baz)\.org' testdata.txt Postfix uses PCRE by default. You can do the same sort of trick there: just run 'pcregrep' rather than 'grep -E' However, note that the regexes in dovecot sieve scripts are subject to a level of shell expansion. (Not sure what happens with postfix.) This means various special characters are going to need to be escaped by preceding them with a *pair* of backslashes. So, in the example above, the bit that says '\.' (meaning override the usual meaning of '.' as a wildcard that will match any character, and instead match a literal '.') would have to be entered into your sieve script as '\\\.' If in doubt, simply pound on the backslash key a few more times...

What I need is one that I can write the expression in and then have it test the expression for both syntax and against example text that I enter.

Re: Regular Expression Editor
In general I think most people would use command line tools to test expressions. Although I favor command line tools for most of my work (if only, because it can work remotely, through a slow phone connection, across the world); I like The Regex Coach (GUI tool) because it highlights the various strings and substrings matched. Also I like it because the regex (as far as I have used it) have the exact syntax of Perl, so it is just a matter of cut paste: usefull to find a mistake in a long and intricated regex.
