replace this:
// setting email addressess user wants send message message.setrecipients(message.recipienttype.bcc, getemailslist(emails)); with this:
// setting email addressess user wants send message (string emailbcc : emails) { message.addrecipient(message.recipienttype.bcc, new internetaddress(emailbcc)); } i've had problems setrecipients() before, never addrecipient().
if keep having issues, we'll need stacktrace exact error / exception you're getting.
