Heh... I totally forgot about Repeatstring()...
<cfscript>
function maskemail(email)
{
name = listfirst(email, '@');
tld = listlast(email, '.');
maskedemail = name & '@' & repeatstring('*',
len(replace(replace(email, name, ''), tld, ''))-2) & '.' & tld;
return maskedemail;
}
</cfscript>
<cfoutput>#maskemail('[EMAIL PROTECTED]')#</cfoutput>
....and this one actually uses the variables I set hehe

Subject: Re: Need regular expression in REReplace for email
Hi Karl
My regular expressions are very rusty to say the least.. but I had a
go using string manipulation which you could put in to a UDF.... seems
to work ok with a variety of emails and may at least get you started.
I am sure that there is a better/easier way probably using regular
expressions...
<cffunction name="emailStars" returntype="string">
<cfargument name="email" required="yes" type="string">
<cfset atPosition = find("@",email)>
<cfset lastPeriod = Len(listLast(email, ".")) + 1>
<cfset starlength = Len(email) - (lastPeriod) - atPosition>
<cfset stars = repeatstring("*",starlength)>
<cfset emailStar = left(email,atPosition) & stars & "." &
listLast(email, ".")>
<cfreturn emailStar>
</cffunction>
<cfset Email = "[EMAIL PROTECTED]">
<cfset newEmail = emailStars(email)>
<cfdump var="#variables#">
<cfoutput>#email# (original)<br />#newEmail# (stars)</cfoutput>
