我正在致力於一個電子郵件客戶端,它將連接到Gmail郵箱並檢索特定的電子郵件。IMAP響應限制的大小
現在我可以連接到我的郵箱,並且可以檢索部分電子郵件,而不是所有電子郵件,無論我的緩衝區有多大,我仍然只從我的電子郵件中獲得1400個字符,然後爲郵件正文的其餘部分填充空字符。
你可以找到一個截屏的電子郵件正文在這個環節提前

郵政編碼請。聽起來就像你只收到郵件的第一個數據包。 – Joe 2012-07-11 16:23:39

什麼是_imapClient,什麼是設置ReceiveBufferSize?我猜你必須根據其他事件/觸發反覆調用。 – Joe 2012-07-12 11:08:24
