spring-integration

I need to handle emails from about 30 addresses. I implement this in a way where all emails going to one DirectChannel and after to Receiver . In Receiver I can understand from what address is message comes, to do this I create CustomMessageSource that wraps javax.mail.Message to my own type that contains javax.mail.Message and some Enum . Looks like this is not a good decision, cause I can use @Transformer , but how can I use it if I have only 1 channel? That was the first question. Second question: Should I use ONE channel and ONE receiver for all that addresses? Or better to have channel

I am novice in Spring and I don't like code duplication. I wrote one ImapAdapter that works fine: @Component public class GeneralImapAdapter { private Logger logger = LoggerFactory.getLogger(getClass()); @Autowired private EmailReceiverService emailReceiverService; @Bean @InboundChannelAdapter(value = "emailChannel", poller = @Poller(fixedDelay = "10000", taskExecutor = "asyncTaskExecutor")) public MessageSource<javax.mail.Message> mailMessageSource(MailReceiver imapMailReceiver) { return new MailReceivingMessageSource(imapMailReceiver); } @Bean @Value("imaps://<login>:<pass>@<url>:993/inbox")
