The javax.mail.internet.Address class returns an address exception when some of the email addresses contain a blank. For example, email@example.com is OK, but this type of address, John Smith/City/COMP/@COMPUS, will cause the address exception. This is a valid address format, so why doesn't the java class handle it? Do any Java experts out there have a solution to avoid this problem? Your help would be greatly appreciated. Thank you.
