InternetAddress Parse is going to be your friend   See the worked example below      String to    med joe com  maz frank com  jezz jam com   String toCommaAndSpaces    med joe com maz frank com  jezz jam com      Parse a comma-separated list of email addresses  Be strict  Require comma separated list   If strict is true  many  but not all  of the RFC822 syntax rules for emails are enforced    msg setRecipients Message RecipientType CC  InternetAddress parse to  true     Parse comma space-separated list  Cut some slack  We allow spaces seperated list as well  plus invalid email formats   msg setRecipients Message RecipientType BCC  InternetAddress parse toCommaAndSpaces  false

If you invoke addRecipient multiple times it will add the given recipient to the list of recipients of the given time  TO  CC  BCC   For example   message addRecipient Message RecipientType CC  InternetAddress parse  abc abc com     message addRecipient Message RecipientType CC  InternetAddress parse  abc def com     message addRecipient Message RecipientType CC  InternetAddress parse  ghi abc com       Will add the 3 addresses to CC    If you wish to add all addresses at once you should use setRecipients or addRecipients and provide it with an array of addresses  Address   cc   new Address    InternetAddress parse  abc abc com                                   InternetAddress parse  abc def com                                    InternetAddress parse  ghi abc com     message addRecipients Message RecipientType CC  cc       You can also use InternetAddress parse to parse a list of addresses  message addRecipients Message RecipientType CC                         InternetAddress parse  abc abc com abc def com ghi abc com
