I would come up with the following (mind that I am just getting started with regexes as well): "/^\s*[a-z][a-z0-9]*(\.[a-z0-9][a-z0-9-]*)*(\+[a-z0-9]*)? @[a-z0-9][a-z0-9-]*(\.[a-z0-9][a-z0-9-]*)*\.[a-z]{2,6}\s*$/i" (added linebreak due to technical reasons problems with php.net) The only problem that still applies, is the dashes in the wrong places (though the only wrong place is right before a dot). Fixing this is tricky, I tried using lookbehind, but that did not work. You do have to keep in mind that there may only be one letter between two dots.
