我正在使用java邮件，并且在尝试从包含200多封邮件的电子邮件中获取收件人时收到MessagingException。
相同的代码适用于较少数量的收件人：
Address[] recipients = message.getRecipients(javax.mail.Message.RecipientType.TO);
例外：
javax.mail.MessagingException: Failed to load IMAP envelope
at com.sun.mail.imap.IMAPMessage.loadEnvelope(IMAPMessage.java:1274) ~[mail-1.4.7.jar:1.4.7]
at com.sun.mail.imap.IMAPMessage.getRecipients(IMAPMessage.java:298) ~[mail-1.4.7.jar:1.4.7]
IMAP追踪：
