I've got a problem with outgoing mail for a single user. Her synonym, as all of mine are, is setup as her first initial and lastname, e.g. email@example.com it's just that her last name is hyphenated. firstname.lastname@example.org Mercury's refusing to allow her to send mail, indicating an "invalid from address". I thought periods "." and hyphens "-" where OK in addresses. Is it just that they can't BOTH be used in a single address?
