Answer 1

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";

1. Parse a comma-separated list of email addresses. Be strict. Require comma separated list.

2. 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));
   

3. 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));
