See the advice in Perl FAQ #9 "How do I check a valid mail address?" The command 'perldoc -q address' will get you that entry. Synopsis: it is difficult to write a regular expression to parse and validate an email address. The modules Email::Valid and RFC::RFC822::Address might help. I usually just check to see if the string contains the '@' character. I might also delete any character that is not in [a-zA-Z0-9.:;_@<>-] (but see the longer RE in the FAQ). -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
