//your code here...The code examples below show how to connect to an IMAP mailbox and get messages that have the string "Newsletter" in the subject and were sent today. ExchangeClient client = new ExchangeClient("http://MachineName/exchange/Username","username", "password", "domain"); SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss"); // Query building by means of ExchangeQueryBuilder class ExchangeQueryBuilder builder = new ExchangeQueryBuilder(); // Subject contains "Newsletter" builder.getSubject().contains("Newsletter"); // Emails that arrived today try {builder.getInternalDate().on(sdf.parse("10/05/2015 10:00:00"));} catch (ParseException e) {e.printStackTrace(); } // Build the query MailQuery query = builder.getQuery(); // Get list of messages ExchangeMessageInfoCollection messages = client.listMessages(client.getMailboxInfo().getInboxUri(), query, false); System.out.println("Imap: " + messages.size()+ " message(s) found."); IEWClient can also be used for this purpose as shown below: // Create instance of IEWSClient class by giving credentials IEWSClient client = EWSClient.getEWSClient("https://outlook.office365.com/ews/exchange.asmx", "testUser", "pwd", "domain"); SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss"); // Query building by means of ExchangeQueryBuilder class ExchangeQueryBuilder builder = new ExchangeQueryBuilder(); // Subject contains "Newsletter" builder.getSubject().contains("Newsletter"); // Emails that arrived today try {builder.getInternalDate().on(sdf.parse("10/05/2015 10:00:00"));} catch (ParseException e) {e.printStackTrace(); } // Build the query MailQuery query = builder.getQuery(); // Get list of messages ExchangeMessageInfoCollection messages = client.listMessages(client.getMailboxInfo().getInboxUri(), query, false); System.out.println("Imap: " + messages.size()+ " message(s) found."); Get Messages that Meet Specific Criteria //Code Samples: Today's Date // Emails that arrived today MailQueryBuilder builder = new MailQueryBuilder(); builder.getInternalDate().on(new Date()); //Code Samples: Date Range builder.getInternalDate().beforeOrEqual(new Date()); builder.getInternalDate().since(new Date(new Date().getTime() + TimeUnit.DAYS.toDays(1))); //Code Samples: Specific Sender // Get emails from specific sender builder.getFrom().contains("saqib.razzaq@127.0.0.1"); //Code Samples: Specific Domain // Get emails from specific domain builder.getFrom().contains("SpecificHost.com"); //Code Samples: Specific Recipient // Get emails sent to specific recipient builder.getTo().contains("recipient"); //Code Samples: By MessageID // Get email delivery notifications builder.getMessageId().equals("MessageID"); //Code Samples: Combining Queries with AND MailQueryBuilder builder = new MailQueryBuilder(); // Emails from specific host builder.getFrom().contains("SpecificHost.com"); // AND all emails that arrived before today builder.getInternalDate().before(new Date()); // AND all emails that arrived since 7 days ago builder.getInternalDate().since(new Date(new Date().getTime() + TimeUnit.DAYS.toDays(-7))); //Case-Sensitive Email Filtering //IgnoreCase is True MailQueryBuilder builder1 = new MailQueryBuilder(); builder1.getFrom().contains("tesT", true); MailQuery query1 = builder1.getQuery();
