Hi Tom, Let me suggest a scenario where you might not want your domain names as part of the user name. Let's say you've happily been using LOCAL-GUYS ISP for the past umpteen years with your @lguys.net addresses. Along comes NATIONAL-ISP and gobbles up LOCAL-GUYS, getting all their customers in the bargain, and telling you they will discontinue the use of lguys.net, and all of your e-mail address belongs to us......I mean, you must now use @hugeco.com. Same thing applies if you work for mycompany.com and they get bought by bigco.com. Been there, done that, a couple of times now. Think more of the user name entries being 'unique keys' as opposed to 'user names' or e-mail addresses. Also, postfix is quite happy about validating against the aliases for receipt validation. I have arbitrary user names, and store the actual e-mail addresses as aliases. --Keith
